Cardiovascular Practice Questions Questions
Question 1 of 5
The client has developed neutropenia from a medication. What medication might this be?
Correct Answer: B
Rationale: The correct answer is B: Captopril. Captopril is an ACE inhibitor that can cause neutropenia as a rare side effect by suppressing bone marrow function. Metoprolol (A) is a beta-blocker and does not typically cause neutropenia. Lisinopril (C) is also an ACE inhibitor, but it is less likely to cause neutropenia compared to captopril. Guanfacine (D) is an alpha-2 adrenergic agonist and is not associated with neutropenia. Therefore, based on the mechanism of action and side effect profile, captopril is the most likely medication to have caused neutropenia in the client.
Question 2 of 5
The client is on an ADP receptor blocker for the prevention of recurrent myocardial infarction. What does the nurse expect when the client develops hemorrhaging and a low platelet count?
Correct Answer: C
Rationale: Rationale for Correct Answer (C): The client developing hemorrhaging and a low platelet count while on an ADP receptor blocker suggests thrombotic thrombocytopenia. Thrombotic thrombocytopenia is a rare but serious adverse effect characterized by the formation of blood clots and a decrease in platelet count. This condition can lead to both bleeding and clotting issues, explaining the hemorrhaging and low platelet count in the client. Summary of Incorrect Choices: A: The low platelet count is not an anticipated reaction to taking an ADP receptor blocker. While some antiplatelet medications can cause decreased platelet count, thrombotic thrombocytopenia is a more specific and severe condition. B: The combination of ADP receptor blockers with aspirin is a common therapy for preventing cardiovascular events but does not directly explain the development of thrombotic thrombocytopenia. D: Simply taking too much of the ADP receptor blocker
Question 3 of 5
The client is experiencing a drug-drug interaction with niacin. Which drug has a drug-drug interaction with niacin?
Correct Answer: B
Rationale: The correct answer is B: Statin drugs. Niacin can increase the risk of myopathy when used with statins. Statins are known to cause muscle-related side effects, and combining them with niacin can further exacerbate this risk. Aspirin (A), Theophylline (C), and Digoxin (D) do not have significant drug-drug interactions with niacin. Therefore, the correct choice is B based on the known interaction between niacin and statin drugs leading to an increased risk of myopathy.
Question 4 of 5
The client has been found to have a normal cardiac output. What value represents a normal cardiac output?
Correct Answer: C
Rationale: The correct answer is C (4 l/min) as it represents the normal cardiac output value for an average adult at rest. Cardiac output is the volume of blood pumped by the heart per minute. Normal cardiac output ranges from 4-8 liters per minute in adults. Options A, B, and D are incorrect as they fall below or exceed the normal range, indicating either insufficient or excessive blood being pumped by the heart, which can lead to health issues.
Question 5 of 5
The client has atrial fibrillation. The treatment of choice to convert to normal sinus rhythm is what?
Correct Answer: B
Rationale: The correct answer is B: Cardioversion. Cardioversion is the treatment of choice to electrically or pharmacologically convert atrial fibrillation to normal sinus rhythm. Digoxin (A) is used for rate control, not rhythm conversion. Metoprolol (C) is a beta-blocker that helps control heart rate but does not convert rhythm. Verapamil (D) is a calcium channel blocker that can worsen atrial fibrillation and is contraindicated for rhythm conversion.
