Cardiovascular System Test Questions and Answers | Latest Version | 2025/2026 | Correct & Verified
What is the primary purpose of angiotensin-converting enzyme (ACE) inhibitors in treating cardiovascular diseases?✔✔ACE inhibitors help to relax blood vessels, lower blood pressure, and improve heart function.
What is the most common side effect of beta-blockers?✔✔Bradycardia, or slow heart rate, is the most common side effect of beta-blockers.
What should a nurse monitor closely when administering digoxin to a patient with heart failure?✔✔The nurse should monitor the patient’s heart rate and potassium levels, as digoxin toxicity can occur with low potassium levels or irregular heart rates.
How do calcium channel blockers work to treat hypertension?✔✔Calcium channel blockers relax blood vessels and reduce the workload on the heart, thereby lowering blood pressure. 1 / 3
2
What is the primary action of nitrates in patients with angina?✔✔Nitrates relax and dilate blood vessels, improving blood flow to the heart and reducing the heart's oxygen demand.
Which lab value is most important to check before administering a diuretic to a patient with heart failure?✔✔Serum potassium levels should be monitored, as diuretics can cause potassium imbalances.
What should a nurse educate a patient about when taking anticoagulants such as warfarin?✔✔The nurse should educate the patient about the importance of monitoring for signs of bleeding, avoiding injury, and maintaining consistent vitamin K intake.
Why is monitoring blood pressure crucial when a patient is taking ACE inhibitors?✔✔ACE inhibitors can cause a significant drop in blood pressure, especially after the first dose, so blood pressure should be closely monitored.
What is a potential complication of using high doses of beta-blockers?✔✔High doses of beta-blockers can lead to heart block or severe bradycardia. 2 / 3
3
How does atorvastatin (a statin) help in managing cardiovascular disease?✔✔Atorvastatin reduces cholesterol levels, specifically low-density lipoprotein (LDL), thus lowering the risk of heart attack and stroke.
What is a common side effect of nitrates that nurses should inform patients about?✔✔A common side effect of nitrates is a headache due to the vasodilation effect.
What should a nurse do if a patient taking anticoagulants experiences an injury or bleeding?✔✔The nurse should immediately assess the extent of the injury and notify the healthcare provider, as excessive bleeding is a potential complication.
How do diuretics help patients with hypertension?✔✔Diuretics help by reducing fluid volume in the body, lowering blood pressure by decreasing the workload on the heart.
What is the primary reason for using a vasodilator like hydralazine in heart failure patients?✔✔Hydralazine helps to relax the blood vessels, reducing the resistance against which the heart has to pump, thus improving heart function.
