When a patient has chest pain and the etiology is not likely to be cardiac ischemia, a GI disorder such as GERD is the likely cause. Other common GI disorders associated with chest pain are ulcer disease, cholelithiasis, duodenitis, and gastritis. If a woman, age 48,has chest pain with no risk factors, ischemic heart disease is unlikely<br \/>\nto be the cause. By age 55\u201360, however, the protective effect of menstruation and naturally-occurring estrogen has worn off, and the rates of CAD will at least equal the rates in men.

Immediate high\u2011quality CPR and prompt defibrillation (unsynchronized shock) are the priority, followed by advanced cardiac life support measures (epinephrine, antiarrhythmics such as amiodarone or lidocaine as indicated).<\/h5>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"flex\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n                        <\/div>\n                        <div class='ays_questtion_explanation' style='display:none'>\n                            \n                        <\/div>\n                        <div class='ays-quiz-additonal-box'>\n                            \n                        <\/div>   \n                        \n                        \n                    <\/div>\n                <\/div><div class='step ' data-question-id='187' data-type='radio'>\n                    \n                    \n                    <p class='ays-question-counter animated'>170 \/ 236<\/p>\n                    <div class='ays-abs-fs'>\n                        \n                        <div class='ays_quiz_question'>\n                                <h4>An elderly patient presents to the ER with tachycardia.

Choice of rate-control agent (beta\u2011blocker vs nondihydropyridine calcium\u2011channel blocker vs digoxin) depends on comorbidities (e.g., heart failure, bronchospasm).<\/h5>\n<\/li>\n<\/ul>\n\n                        <\/div>\n                        <div class='ays_questtion_explanation' style='display:none'>\n                            \n                        <\/div>\n                        <div class='ays-quiz-additonal-box'>\n                            \n                        <\/div>   \n                        \n                        \n                    <\/div>\n                <\/div><div class='step ' data-question-id='179' data-type='radio'>\n                    \n                    \n                    <p class='ays-question-counter animated'>178 \/ 236<\/p>\n                    <div class='ays-abs-fs'>\n                        \n                        <div class='ays_quiz_question'>\n                                <h4>A patient with chest pain has T-wave inversion and ST changes on ECG.

Tachycardia raises cardiac workload and oxygen demand but shortens diastole (when most coronary perfusion occurs) and does not reliably increase myocardial blood supply; excessive tachycardia can even reduce coronary perfusion.<\/h5>\n\n                        <\/div>\n                        <div class='ays_questtion_explanation' style='display:none'>\n                            \n                        <\/div>\n                        <div class='ays-quiz-additonal-box'>\n                            \n                        <\/div>   \n                        \n                        \n                    <\/div>\n                <\/div><div class='step ' data-question-id='176' data-type='radio'>\n                    \n                    \n                    <p class='ays-question-counter animated'>181 \/ 236<\/p>\n                    <div class='ays-abs-fs'>\n                        \n                        <div class='ays_quiz_question'>\n                                <h4>The question asks to identify the best anti-hypertensive (HTN) drug for patients who have both hyperaldosteronism and hypertension.<\/h4>\n\n                            <\/div>\n                            \n                        <div class='ays-quiz-answers ays_list_view_container  '>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-176]' id='ays-answer-733-2' value='733'\/>\n\n                <label for='ays-answer-733-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Spironolactone<\/label><label for='ays-answer-733-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-176]' id='ays-answer-734-2' value='734'\/>\n\n                <label for='ays-answer-734-2' class='  ays_position_initial  ays-quiz-keyboard-label'>ACEI (Angiotensin-Converting Enzyme Inhibitor)<\/label><label for='ays-answer-734-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-176]' id='ays-answer-735-2' value='735'\/>\n\n                <label for='ays-answer-735-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Beta Blocker<\/label><label for='ays-answer-735-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div><script>\n            if(typeof window.quizOptions_2 === 'undefined'){\n                window.quizOptions_2 = [];\n            }\n            window.quizOptions_2['176'] = 'W10=';<\/script><\/div>                        \n                        \n                        \n                        <div class='ays_buttons_div'>\n                        \n                        <i class=\"ays_fa ays_fa_arrow_left ays_previous action-button ays_arrow ays-quiz-keyboard-active ays_display_none\" tabindex='0'><\/i>\n                        <input type='button' class='ays_previous action-button ays-quiz-keyboard-active ' value='Prev' \/>\n                        \n                        <i class=\"ays_fa ays_fa_arrow_right ays_next action-button ays_arrow ays_next_arrow ays-quiz-keyboard-active ays_display_none\" tabindex='0'><\/i>\n                        <input type='button' class='ays_next action-button ays-quiz-keyboard-active ' value='Next' \/>\n                    <\/div>\n                        \n                        <div class='wrong_answer_text ' style='display:none'>\n                            <h5>Spironolactone is an aldosterone antagonist.

Atrial septal defect (ASD)<\/strong>\u00a0(correct)<\/h5>\n<ul>\n<li>\n<h5>Most ASDs (e.g., secundum, sinus venosus) produce a left\u2011to\u2011right shunt at the atrial level that preferentially increases right atrial and right ventricular volumes and pulmonary blood flow. The left atrium typically does\u00a0<strong>not<\/strong>\u00a0receive an increased volume load from the ASD itself (and may even be normal or small in size).

However, the classic drug most notorious for causing a hypertensive crisis on abrupt cessation is clonidine.

      <h5><strong>Explanation:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>Cardiac Troponins (specifically Troponin I and Troponin T)<\/strong>\u00a0are the\u00a0<strong>gold standard biomarkers<\/strong>\u00a0for diagnosing acute myocardial infarction (AMI). They are also crucial for\u00a0<strong>risk stratification and prognosis<\/strong>\u00a0in patients with AMI and acute coronary syndromes.<\/h5>\n<\/li>\n<li>\n<h5>The degree of troponin elevation is directly correlated with the size of myocardial necrosis and, consequently, with the patient's prognosis (higher levels often indicate a worse prognosis).<\/h5>\n<\/li>\n<\/ul>\n<h5><strong>Why Troponin is the best answer for assessing risk\/prognosis:<\/strong><\/h5>\n<ol>\n<li>\n<h5><strong>Sensitivity and Specificity:<\/strong>\u00a0Troponins are highly sensitive and specific for myocardial injury.<\/h5>\n<\/li>\n<li>\n<h5><strong>Duration of Elevation:<\/strong>\u00a0Unlike CK-MB, troponins remain elevated for a longer period (1-2 weeks), which allows for diagnosis even if a patient presents several days after the onset of symptoms. This prolonged elevation also makes them superior for assessing the extent of damage over time and thus, long-term prognosis.<\/h5>\n<\/li>\n<li>\n<h5><strong>Prognostic Value:<\/strong>\u00a0Elevated troponin levels, even without overt AMI, are associated with an increased risk of adverse cardiac events in various cardiac conditions. In AMI, higher peak troponin levels correlate with larger infarct size, greater ventricular dysfunction, and worse clinical outcomes (e.g., increased mortality, reinfarction, heart failure).<\/h5>\n<\/li>\n<\/ol>\n<h5><strong>Why other options are less suitable for assessing risk\/prognosis:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>A. CK-MB (Creatine Kinase-MB):<\/strong>\u00a0While CK-MB is also used to diagnose AMI, its elevation is more transient (returns to normal within 2-3 days). This makes it less ideal for assessing long-term risk or prognosis compared to troponin. However, its faster return to normal makes it useful for detecting reinfarction that occurs days after the initial event when troponin levels might still be elevated from the first event.<\/h5>\n<\/li>\n<li>\n<h5><strong>B. Myoglobin:<\/strong>\u00a0Myoglobin is an early marker of myocardial injury but lacks cardiac specificity (can be elevated due to skeletal muscle injury) and its levels return to normal very quickly.

They are also crucial for\u00a0<strong>risk stratification and prognosis<\/strong>\u00a0in patients with AMI and acute coronary syndromes.<\/h5>\n<\/li>\n<li>\n<h5>The degree of troponin elevation is directly correlated with the size of myocardial necrosis and, consequently, with the patient's prognosis (higher levels often indicate a worse prognosis).<\/h5>\n<\/li>\n<\/ul>\n<h5><strong>Why Troponin is the best answer for assessing risk\/prognosis:<\/strong><\/h5>\n<ol>\n<li>\n<h5><strong>Sensitivity and Specificity:<\/strong>\u00a0Troponins are highly sensitive and specific for myocardial injury.<\/h5>\n<\/li>\n<li>\n<h5><strong>Duration of Elevation:<\/strong>\u00a0Unlike CK-MB, troponins remain elevated for a longer period (1-2 weeks), which allows for diagnosis even if a patient presents several days after the onset of symptoms. This prolonged elevation also makes them superior for assessing the extent of damage over time and thus, long-term prognosis.<\/h5>\n<\/li>\n<li>\n<h5><strong>Prognostic Value:<\/strong>\u00a0Elevated troponin levels, even without overt AMI, are associated with an increased risk of adverse cardiac events in various cardiac conditions. In AMI, higher peak troponin levels correlate with larger infarct size, greater ventricular dysfunction, and worse clinical outcomes (e.g., increased mortality, reinfarction, heart failure).<\/h5>\n<\/li>\n<\/ol>\n<h5><strong>Why other options are less suitable for assessing risk\/prognosis:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>A. CK-MB (Creatine Kinase-MB):<\/strong>\u00a0While CK-MB is also used to diagnose AMI, its elevation is more transient (returns to normal within 2-3 days). This makes it less ideal for assessing long-term risk or prognosis compared to troponin. However, its faster return to normal makes it useful for detecting reinfarction that occurs days after the initial event when troponin levels might still be elevated from the first event.<\/h5>\n<\/li>\n<li>\n<h5><strong>B. Myoglobin:<\/strong>\u00a0Myoglobin is an early marker of myocardial injury but lacks cardiac specificity (can be elevated due to skeletal muscle injury) and its levels return to normal very quickly.

      <h5><strong>Explanation:<\/strong><br \/>\nThe question specifically asks which\u00a0<em>single<\/em>\u00a0drug from the given options improves survival in congestive heart failure (CHF).<\/h5>\n<ul>\n<li>\n<h5><strong>Spironolactone<\/strong>\u00a0is a mineralocorticoid receptor antagonist (MRA) that has been shown to significantly improve survival and reduce hospitalizations in patients with heart failure with reduced ejection fraction (HFrEF), particularly in moderate to severe stages (NYHA Class II-IV). It achieves this by blocking the harmful effects of aldosterone on the heart and kidneys, such as fibrosis, remodeling, and potassium wasting.<\/h5>\n<\/li>\n<\/ul>\n<h5><strong>Why other options are not the primary answer for improving survival:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>A. Digoxin:<\/strong>\u00a0Digoxin is a cardiac glycoside that improves symptoms and reduces hospitalizations for heart failure, but it\u00a0<strong>does not improve overall survival<\/strong>\u00a0in heart failure patients. It primarily acts by increasing cardiac contractility and slowing heart rate.<\/h5>\n<\/li>\n<li>\n<h5><strong>B. Hydralazine:<\/strong>\u00a0While hydralazine (often combined with isosorbide dinitrate) has been shown to improve survival in specific subgroups of heart failure patients, particularly African Americans with HFrEF or those who cannot tolerate ACE inhibitors\/ARBs, it is not considered a first-line agent for\u00a0<em>general<\/em>\u00a0survival benefit across all CHF patients in the same way that MRAs (like spironolactone), ACE inhibitors\/ARBs, and beta-blockers are. If \"hydralazine-isosorbide dinitrate combination\" was an option, it would be a stronger contender for survival benefit in specific cases, but hydralazine alone is typically used for symptom relief and afterload reduction.<\/h5>\n<\/li>\n<\/ul>\n<h5>The explanation provided in the image reinforces this: \"The single most important fact about the 'further management' of CHF is that mortality is decreased by ACE\/ ARB, beta-blockers, and spironolactone. Digoxin decreases symptoms but does not lower mortality.\" It also notes: \"Spironolactone has been shown to decrease mortality in such patients who are New York Heart Association class IV.\"<\/h5>\n<h5>Therefore, among the given single-drug options,\u00a0<strong>Spironolactone<\/strong>\u00a0is the correct answer for improving survival in CHF.<\/h5>\n\n                        <\/div>\n                        <div class='right_answer_text ' style='display:none'>\n                            <h5><strong>Explanation:<\/strong><br \/>\nThe question specifically asks which\u00a0<em>single<\/em>\u00a0drug from the given options improves survival in congestive heart failure (CHF).<\/h5>\n<ul>\n<li>\n<h5><strong>Spironolactone<\/strong>\u00a0is a mineralocorticoid receptor antagonist (MRA) that has been shown to significantly improve survival and reduce hospitalizations in patients with heart failure with reduced ejection fraction (HFrEF), particularly in moderate to severe stages (NYHA Class II-IV).

Digoxin decreases symptoms but does not lower mortality.\" It also notes: \"Spironolactone has been shown to decrease mortality in such patients who are New York Heart Association class IV.\"<\/h5>\n<h5>Therefore, among the given single-drug options,\u00a0<strong>Spironolactone<\/strong>\u00a0is the correct answer for improving survival in CHF.<\/h5>\n\n                        <\/div>\n                        <div class='ays_questtion_explanation' style='display:none'>\n                            \n                        <\/div>\n                        <div class='ays-quiz-additonal-box'>\n                            \n                        <\/div>   \n                        \n                        \n                    <\/div>\n                <\/div><div class='step ' data-question-id='222' data-type='radio'>\n                    \n                    \n                    <p class='ays-question-counter animated'>213 \/ 236<\/p>\n                    <div class='ays-abs-fs'>\n                        \n                        <div class='ays_quiz_question'>\n                                <h4>Common cause of secondary hypertension in young female?<\/h4>\n\n                            <\/div>\n                            \n                        <div class='ays-quiz-answers ays_list_view_container  '>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-222]' id='ays-answer-926-2' value='926'\/>\n\n                <label for='ays-answer-926-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Pheochromocytoma<\/label><label for='ays-answer-926-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-222]' id='ays-answer-927-2' value='927'\/>\n\n                <label for='ays-answer-927-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Cushing disease<\/label><label for='ays-answer-927-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-222]' id='ays-answer-928-2' value='928'\/>\n\n                <label for='ays-answer-928-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Renal artery stenosis<\/label><label for='ays-answer-928-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-222]' id='ays-answer-929-2' value='929'\/>\n\n                <label for='ays-answer-929-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Renal parenchymal disease<\/label><label for='ays-answer-929-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div><script>\n            if(typeof window.quizOptions_2 === 'undefined'){\n                window.quizOptions_2 = [];\n            }\n            window.quizOptions_2['222'] = 'W10=';<\/script><\/div>                        \n                        \n                        \n                        <div class='ays_buttons_div'>\n                        \n                        <i class=\"ays_fa ays_fa_arrow_left ays_previous action-button ays_arrow ays-quiz-keyboard-active ays_display_none\" tabindex='0'><\/i>\n                        <input type='button' class='ays_previous action-button ays-quiz-keyboard-active ' value='Prev' \/>\n                        \n                        <i class=\"ays_fa ays_fa_arrow_right ays_next action-button ays_arrow ays_next_arrow ays-quiz-keyboard-active ays_display_none\" tabindex='0'><\/i>\n                        <input type='button' class='ays_next action-button ays-quiz-keyboard-active ' value='Next' \/>\n                    <\/div>\n                        \n                        <div class='wrong_answer_text ' style='display:none'>\n                            <h5><strong>Explanation:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>Secondary hypertension<\/strong>\u00a0is high blood pressure caused by an identifiable underlying condition.

In such cases, if the patient presents early enough (typically within 12 hours of symptom onset) and has no contraindications, thrombolytic therapy becomes the preferred reperfusion strategy to initiate reperfusion quickly. The question context implies a GP decision, which often occurs in settings where a cath lab is not immediately accessible.<\/h5>\n<h5><strong>Why other options are incorrect:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>A. More than 12 hours have elapsed since the onset of pain:<\/strong>\u00a0Thrombolytic therapy is most effective when administered early, typically within the first 6-12 hours of symptom onset. Beyond 12 hours, the benefit significantly diminishes, and primary PCI becomes the preferred strategy if feasible, or conservative management is often pursued. So, administering thrombolytics\u00a0<em>after<\/em>\u00a012 hours is generally not indicated and carries more risk than benefit.<\/h5>\n<\/li>\n<li>\n<h5><strong>B. Clinical suspicion remains despite a normal ECG:<\/strong>\u00a0Thrombolytics are indicated for\u00a0<em>ST-segment elevation<\/em>\u00a0MI (STEMI). A normal ECG (without ST elevation or new LBBB) would rule out STEMI, making thrombolytic therapy inappropriate as it targets the thrombus causing the ST elevation.

However, intramuscular injections are generally avoided in patients who may receive thrombolytics due to the risk of hematoma formation. The route of opiate administration does not dictate the choice of reperfusion strategy.<\/h5>\n<\/li>\n<\/ul>\n<h5>Therefore, the critical factor for opting for thrombolysis, especially in a setting where a GP might be making the initial decision, is the inability to achieve timely primary PCI (i.e., exceeding the 90-minute door-to-balloon time for PCI).<\/h5>\n\n                        <\/div>\n                        <div class='right_answer_text ' style='display:none'>\n                            <h5><strong>Explanation:<\/strong><br \/>\nThis question pertains to the crucial decision-making in the early management of ST-segment elevation myocardial infarction (STEMI), where reperfusion therapy is paramount.

The route of opiate administration does not dictate the choice of reperfusion strategy.<\/h5>\n<\/li>\n<\/ul>\n<h5>Therefore, the critical factor for opting for thrombolysis, especially in a setting where a GP might be making the initial decision, is the inability to achieve timely primary PCI (i.e., exceeding the 90-minute door-to-balloon time for PCI).<\/h5>\n\n                        <\/div>\n                        <div class='ays_questtion_explanation' style='display:none'>\n                            \n                        <\/div>\n                        <div class='ays-quiz-additonal-box'>\n                            \n                        <\/div>   \n                        \n                        \n                    <\/div>\n                <\/div><div class='step ' data-question-id='228' data-type='radio'>\n                    \n                    \n                    <p class='ays-question-counter animated'>217 \/ 236<\/p>\n                    <div class='ays-abs-fs'>\n                        \n                        <div class='ays_quiz_question'>\n                                <h4>Sudden cardiac arrest means that the heart<\/h4>\n\n                            <\/div>\n                            \n                        <div class='ays-quiz-answers ays_list_view_container  '>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-228]' id='ays-answer-950-2' value='950'\/>\n\n                <label for='ays-answer-950-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Stops beating<\/label><label for='ays-answer-950-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-228]' id='ays-answer-951-2' value='951'\/>\n\n                <label for='ays-answer-951-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Beats dangerously slow<\/label><label for='ays-answer-951-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-228]' id='ays-answer-952-2' value='952'\/>\n\n                <label for='ays-answer-952-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Has a cycle of beating and stopping<\/label><label for='ays-answer-952-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div>\n            <div class='ays-field ays_list_view_item ays-quiz-keyboard-active' tabindex='0' >\n                <input type='hidden' name='ays_answer_correct[]' value='0'\/>\n\n                <input type='radio' name='ays_questions[ays-question-228]' id='ays-answer-953-2' value='953'\/>\n\n                <label for='ays-answer-953-2' class='  ays_position_initial  ays-quiz-keyboard-label'>Skips beats<\/label><label for='ays-answer-953-2' class='ays_answer_image ays_answer_image_class ays_empty_before_content'><\/label>\n\n            <\/div><script>\n            if(typeof window.quizOptions_2 === 'undefined'){\n                window.quizOptions_2 = [];\n            }\n            window.quizOptions_2['228'] = 'W10=';<\/script><\/div>                        \n                        \n                        \n                        <div class='ays_buttons_div'>\n                        \n                        <i class=\"ays_fa ays_fa_arrow_left ays_previous action-button ays_arrow ays-quiz-keyboard-active ays_display_none\" tabindex='0'><\/i>\n                        <input type='button' class='ays_previous action-button ays-quiz-keyboard-active ' value='Prev' \/>\n                        \n                        <i class=\"ays_fa ays_fa_arrow_right ays_next action-button ays_arrow ays_next_arrow ays-quiz-keyboard-active ays_display_none\" tabindex='0'><\/i>\n                        <input type='button' class='ays_next action-button ays-quiz-keyboard-active ' value='Next' \/>\n                    <\/div>\n                        \n                        <div class='wrong_answer_text ' style='display:none'>\n                            <h5><strong>Explanation:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>Sudden cardiac arrest (SCA)<\/strong>\u00a0is a medical emergency in which the heart abruptly and unexpectedly stops beating, or beats so inefficiently that it cannot pump blood to the brain and other vital organs.

If he asks, tell him it's okay because he is an apprehensive personality:<\/strong>\u00a0This is also unethical and irresponsible.

<h5><strong>Explanation:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>A. The older we get, the greater is our risk to develop high blood pressure.<\/strong>\u00a0This statement is\u00a0<strong>true<\/strong>. As people age, blood vessels naturally become stiffer and less elastic, which contributes to an increase in blood pressure. This is a well-established risk factor for hypertension.<\/h5>\n<\/li>\n<li>\n<h5><strong>B. Hypertension shows symptoms in most people.<\/strong>\u00a0This statement is\u00a0<strong>false<\/strong>. Hypertension is often called the \"silent killer\" because it typically has no obvious symptoms, even when blood pressure reaches dangerously high levels. Symptoms only appear in severe cases or when target organ damage has occurred.<\/h5>\n<\/li>\n<li>\n<h5><strong>C. Hypertension is inherited so the best way is to take medicines.<\/strong>\u00a0This statement is\u00a0<strong>false<\/strong>. While there is a genetic predisposition to hypertension (it can \"run in families\"), it is not solely inherited. Lifestyle factors (diet, exercise, stress, etc.) play a significant role. Furthermore, medication is one way to manage it, but lifestyle modifications are also crucial and often the first line of treatment or an essential adjunct.<\/h5>\n<\/li>\n<li>\n<h5><strong>D. Sea salt contains lots of mineral so it is good for hypertension.<\/strong>\u00a0This statement is\u00a0<strong>false<\/strong>. Sea salt contains similar amounts of sodium chloride as table salt. While it may contain trace minerals, the sodium content is the primary concern for blood pressure. High sodium intake is a major contributor to hypertension, regardless of whether it comes from table salt or sea salt.<\/h5>\n<\/li>\n<li>\n<h5><strong>E. Being overweight is not related to hypertension.<\/strong>\u00a0This statement is\u00a0<strong>false<\/strong>. Being overweight or obese is a significant and well-documented risk factor for hypertension. Excess weight increases blood volume, puts more strain on the heart, and can contribute to insulin resistance, all of which can elevate blood pressure.<\/h5>\n<\/li>\n<\/ul>\n<hr \/>\n<h5><strong>Summary:<\/strong><br \/>\nThe most accurate statement is that the risk of developing high blood pressure increases with age due to natural changes in the cardiovascular system.<\/h5>\n\n                        <\/div>\n                        <div class='right_answer_text ' style='display:none'>\n                            <h5><strong>Explanation:<\/strong><\/h5>\n<ul>\n<li>\n<h5><strong>A.

While there is a genetic predisposition to hypertension (it can \"run in families\"), it is not solely inherited. Lifestyle factors (diet, exercise, stress, etc.) play a significant role. Furthermore, medication is one way to manage it, but lifestyle modifications are also crucial and often the first line of treatment or an essential adjunct.<\/h5>\n<\/li>\n<li>\n<h5><strong>D. Sea salt contains lots of mineral so it is good for hypertension.<\/strong>\u00a0This statement is\u00a0<strong>false<\/strong>. Sea salt contains similar amounts of sodium chloride as table salt. While it may contain trace minerals, the sodium content is the primary concern for blood pressure. High sodium intake is a major contributor to hypertension, regardless of whether it comes from table salt or sea salt.<\/h5>\n<\/li>\n<li>\n<h5><strong>E. Being overweight is not related to hypertension.<\/strong>\u00a0This statement is\u00a0<strong>false<\/strong>. Being overweight or obese is a significant and well-documented risk factor for hypertension. Excess weight increases blood volume, puts more strain on the heart, and can contribute to insulin resistance, all of which can elevate blood pressure.<\/h5>\n<\/li>\n<\/ul>\n<hr \/>\n<h5><strong>Summary:<\/strong><br \/>\nThe most accurate statement is that the risk of developing high blood pressure increases with age due to natural changes in the cardiovascular system.<\/h5>\n\n                        <\/div>\n                        <div class='ays_questtion_explanation' style='display:none'>\n                            \n                        <\/div>\n                        <div class='ays-quiz-additonal-box'>\n                            \n                        <\/div>   \n                        \n                        \n                    <\/div>\n                <\/div><div class='step ' data-question-id='232' data-type='radio'>\n                    \n                    \n                    <p class='ays-question-counter animated'>223 \/ 236<\/p>\n                    <div class='ays-abs-fs'>\n                        \n                        <div class='ays_quiz_question'>\n                                <h4>A 70-year-old man with diabetes, hyperlipidemia, and tobacco use presents with chest pain (radiating to jaw, nausea, diaphoresis, relieved by nitroglycerin until now) and is found to have a blood pressure of 90\/50 mmHg and a heart rate of 95.
