Question

A nurse is educating a client about the action of aspirin during cardiac events. Which of the following statements by the nurse should be included in the teaching?

Answer 1

Correct Answers:

Taking aspirin will prevent platelet aggregation

Rationale :

🔷Aspirin acts as an antiplatelet agent by irreversibly inhibiting cyclooxygenase (COX-1 and COX-2), which decreases thromboxane A2, a substance responsible for platelet aggregation.

🔷 By preventing platelets from clumping together, aspirin helps to reduce thrombus formation in coronary arteries, particularly during acute coronary syndromes (ACS) like myocardial infarction.

🔷This action helps restore blood flow and reduce infarct size.

🔷 It does not significantly affect blood pressure, oxygen demand, or heart rate.

Answer 2

Correct Answers:

Maintain a BMI less than 25.

Rationale :

🔷Maintaining a body mass index (BMI) under 25 is a vital strategy in clients with cardiomyopathy to

Reduce cardiovascular workload,
Control hypertension,
Improve lipid profiles
Lower the risk for anginal episodes

🔷Obesity increases myocardial oxygen demand, making angina more likely.

🔷Lifestyle changes, including healthy weight maintenance, play a key role in preventing ischemic symptoms and enhancing cardiac function.

Answer 3

Correct Answers:

Report any dark urine after starting the medication.

Rationale :

🔶Simvastatin, like other statins, can cause myopathy or rhabdomyolysis, which leads to muscle breakdown.

🔶One of the earliest signs is dark, tea-colored urine, indicating the presence of myoglobin, a muscle protein that can cause acute kidney injury.

🔶Clients should be taught to report this symptom immediately.

🔶Statins do not typically affect heart rate, cause black stools, or result in orthostatic hypotension.

Answer 4

Correct Answers:

The client has a history of bronchial asthma.

Rationale :

♦️Atenolol is a beta-1 selective blocker, but at higher doses, it may also block beta-2 receptors, leading to bronchoconstriction.

♦️It is contraindicated in clients with bronchial asthma or other obstructive airway diseases, as it may precipitate bronchospasm.

♦️Alternatives should be considered for clients with asthma to prevent exacerbation of respiratory symptoms.

Answer 5

Correct Answers:

Complete an electrocardiogram.

Rationale :

🔹In a client presenting with chest pain, the first and most immediate priority is to perform a 12-lead ECG to assess for ischemia, arrhythmias, or myocardial infarction.

🔹 Time-sensitive identification of ST-segment elevation or depression allows for rapid triage and intervention.

🔹Although labs and imaging are important, the ECG is the fastest way to determine the need for reperfusion therapy and should be completed within 10 minutes of arrival.

Answer 6

Correct Answers:

Diabetes is a risk factor.
Inactivity is a risk factor.
Diet is a risk factor.

Rationale :

✅ Diabetes is a risk factor

Hyperglycemia accelerates atherosclerotic plaque formation and contributes to endothelial dysfunction, increasing the risk of cardiovascular disease.

✅ Inactivity is a risk factor

Physical inactivity contributes to obesity, insulin resistance, and dyslipidemia, all of which exacerbate atherosclerosis.

✅ Diet is a risk factor

A diet high in saturated fats, trans fats, and cholesterol increases low-density lipoprotein (LDL) levels and promotes plaque accumulation within arterial walls.

Answer 7

Correct Answers:

PT/INR level.

Rationale :

🔹Warfarin is monitored using the prothrombin time (PT) and international normalized ratio (INR).

🔹These tests measure the effectiveness of warfarin’s anticoagulant effect by assessing how long it takes for blood to clot.

🔹 A supratherapeutic INR indicates an increased risk of bleeding, which aligns with the client showing signs of hemorrhage.

🔹 PTT is used for heparin; vitamin K levels are not standard monitoring labs.

Answer 8

Correct Answers:

The test will detect abnormal rhythms.

Rationale :

✍️An electrocardiogram (ECG) is a non-invasive test that records the electrical activity of the heart, allowing detection of;

Arrhythmias,
Ischemia,
Conduction blocks,
Previous myocardial infarctions.

✍️ It does not assess ejection fraction (which is done via echocardiogram), nor does it evaluate blood flow visualization.

✍️ It’s essential for diagnosing rhythm disorders and acute coronary events.

Answer 9

Correct Answers:

Heparin and warfarin work together to prevent future clots from forming.

Rationale :

📗Heparin (immediate-acting) and warfarin (delayed onset) are often used together at the beginning of anticoagulation therapy because warfarin takes several days to achieve therapeutic levels.

📗Heparin bridges this gap to prevent new clot formation.

📗Once warfarin reaches a therapeutic INR, heparin can be discontinued.

📗These medications prevent clot propagation and recurrence but do not dissolve existing clots.

Answer 10

Correct Answers:

I should take one tablet at the first indication of chest pain.

Rationale :

🔶Sublingual nitroglycerin should be taken immediately at the onset of chest pain or anginal symptoms to achieve rapid vasodilation and improve oxygen delivery to the myocardium.

🔶The client may repeat the dose every 5 minutes, up to three times, if pain persists, and should seek emergency help if pain is unrelieved after the first dose.

🔶Timing and prompt use are crucial for effective angina management and MI prevention.
