Question

Identify the rhythm below

Answer 1

Correct Answers:

Atrial Fibrillation

Rationale :

🔵 Atrial fibrillation is characterized by irregularly irregular rhythm with no visible P waves on ECG.

🔵 The baseline appears chaotic or fibrillatory, due to rapid atrial activity.

🔵 The ventricular response is irregular, depending on AV node conduction.

🔵 It is a common arrhythmia in elderly clients or those with cardiac conditions.

🔵 Atrial fibrillation increases risk for stroke due to clot formation in the atria.

Answer 2

Correct Answers:

Morphine

Rationale :

🔴 Morphine helps relieve ischemic chest pain unrelieved by nitrates.

🔴 It also reduces preload and afterload, decreasing myocardial oxygen demand.

🔴 It acts as an anxiolytic, helping reduce stress-induced sympathetic drive.

🔴 Morphine can relieve pulmonary congestion by redistributing blood flow.

🔴 It is used cautiously due to respiratory depression and hypotension risk.

Answer 3

Correct Answers:

Do not wear tight clothing over the insertion area
Count your pulse for 1 min each morning.
Request to be scanned with a handheld metal detector when in the airport.

Rationale :

🟡 Do not wear tight clothing over the insertion area – prevents pressure and irritation at the site.

🟡 Count your pulse for 1 min each morning – to detect pacemaker malfunction (bradycardia, loss of capture).

🟡 Request to be scanned with a handheld metal detector – safer than arch scanners; prolonged exposure to full-body scanners can affect function.

Answer 4

Correct Answers:

Evaluating the client for nausea, vomiting, and anorexia

Rationale :

🟢 These are early signs of digoxin toxicity and must be evaluated before administration.

🟢 Digoxin has a narrow therapeutic range, and toxicity can lead to fatal arrhythmias.

🟢 Toxicity risk increases with hypokalemia, common in heart failure clients on diuretics.

🟢 Apical pulse should be taken for a full 60 seconds, not 30.

🟢 Potassium should not be restricted, as low levels increase toxicity risk.

Answer 5

Correct Answers:

Eat foods that contain plenty of potassium.

Rationale :

🔷 Furosemide is a loop diuretic that causes potassium loss via the kidneys.

🔷 Low potassium can lead to muscle cramps, weakness, and dysrhythmias.

🔷 Clients should be taught to eat foods like bananas, oranges, and spinach.

🔷 Taking the drug at bedtime increases nocturia, so it's better taken in the morning.

🔷 Swelling should reduce, not increase, with diuretic therapy.

Answer 6

Correct Answers:

Troponin I
CPK
Myoglobin
Troponin T

Rationale :

🔶 Troponin I and T – most specific cardiac markers, appear 4–6 hrs post-MI, peak at 12–24 hrs.

🔶 CPK (especially CK-MB) – rises within 4–8 hrs, though less specific than troponin.

🔶 Myoglobin – rises early (2–3 hrs) but is non-specific; useful for early detection.

Answer 7

Correct Answers:

Obtain a 12-lead ECG.

Rationale :

🔵 A level of 6.8 mEq/L is severe hyperkalemia, which can cause fatal arrhythmias.

🔵 ECG changes include peaked T waves, widened QRS, and potentially asystole.

🔵 Monitoring cardiac status is the priority, even before lab confirmation.

🔵 Salt substitutes contain potassium chloride and are contraindicated.

🔵 Citrus fruits and bananas are high in potassium, not advised.

Answer 8

Correct Answers:

Leg pain at rest

Rationale :

🟣 Rest pain indicates progression from intermittent claudication to critical limb ischemia.

🟣 It occurs when blood flow is inadequate even without activity.

🟣 Clients often report pain when elevating legs, and relief when legs are dependent.

🟣 Other expected findings include hair loss, shiny skin, thick nails, not flushed legs.

🟣 Legs are typically cool and pale, not warm or red unless dependent.

Answer 9

Correct Answers:

Exertion and anxiety can trigger the pain.

Rationale :

🔴 Stable angina is triggered by increased myocardial oxygen demand—from exercise, stress, or emotion.

🔴 Pain is usually relieved by rest or nitroglycerin, not persistent.

🔴 It typically lasts <15 minutes, not >20 min (that suggests MI).

🔴 Sitting up may help with dyspnea, not necessarily anginal relief.

Answer 10

Correct Answers:

“I must stop smoking"
“I am limiting my intake of fast foods"
“I will stop consuming alcohol."
“I need to monitor my weight."

Rationale :

🟢 Stop smoking – smoking accelerates atherosclerosis and platelet aggregation.

🟢 Limit fast foods – reduces saturated fat and LDL cholesterol intake.

🟢 Stop alcohol – excessive intake increases BP and triglycerides.

🟢 Monitor weight – obesity is a modifiable risk factor for CAD.
