Cardiovascular Test Bank Questions
Question 1 of 5
The client is experiencing a drug-drug reaction by taking aspirin with what other drug?
Correct Answer: C
Rationale: The correct answer is C: Heparin. Aspirin and Heparin can interact leading to increased risk of bleeding due to both drugs affecting blood clotting mechanisms. Aspirin inhibits platelet aggregation while Heparin inhibits clotting factors. Choices A, B, and D do not have a significant drug-drug interaction with aspirin in terms of increased bleeding risk.
Question 2 of 5
The client has a resting heart rate of 80 and a regular rhythm. What is the likely source of electrical activity in this client?
Correct Answer: A
Rationale: The correct answer is A: The sino-atrial node. The SA node is the primary pacemaker of the heart, responsible for initiating the electrical impulses that regulate the heart rate. It is located in the right atrium and typically generates a resting heart rate of around 60-100 beats per minute. In this scenario, with a resting heart rate of 80 and a regular rhythm, the SA node is most likely the source of electrical activity. The other choices (B: AV node, C: Purkinje fibers, D: Bundle of His) are involved in the conduction of electrical impulses within the heart but are not responsible for the initiation of the heartbeat at rest.
Question 3 of 5
The client has a heart rate of 70 and a P wave that comes early and is malformed. What is the likely cause of this?
Correct Answer: B
Rationale: The correct answer is B: Premature atrial contractions. This is because the client's heart rate is normal (70 bpm) and the P wave is early and malformed, which are classic signs of premature atrial contractions. These occur when the electrical impulse in the atria depolarizes prematurely, causing an early P wave on the ECG. Other choices are incorrect because: A: Normal sinus rhythm would not have an early and malformed P wave. C: Frequent PVCs present with a wide QRS complex, not a malformed P wave. D: Ventricular escape rhythm would have a slow heart rate and not an early P wave.
Question 4 of 5
The client is being fitted for a Holter Monitor. What does the nurse tell the client in preparation for the test?
Correct Answer: D
Rationale: The correct answer is D because the client should record the time of any palpable events, such as palpitations, during the Holter Monitor test to provide valuable information to healthcare providers. This step is crucial for correlating symptoms with the recorded heart activity. Choice A is incorrect because clients are encouraged to continue their normal activities during the test. Choice B is incorrect as clients can bathe while wearing the monitor. Choice C is incorrect as the Holter Monitor test typically lasts for 24-48 hours, not just 30 minutes.
Question 5 of 5
Diltiazem (Cardizem) is ordered for a patient with newly diagnosed Prinzmetal’s (variant) angina. When teaching the patient, the nurse will include the information that diltiazem will
Correct Answer: C
Rationale: Step 1: Prinzmetal's angina is caused by coronary artery spasms. Step 2: Diltiazem is a calcium channel blocker that helps relax coronary arteries. Step 3: Relaxing coronary arteries helps decrease spasms. Step 4: Therefore, the correct answer is C: decrease coronary artery spasms. Summary: A is incorrect because diltiazem does not directly affect heart palpitations. B is incorrect because it does not target plaque. D is incorrect because diltiazem does not increase contractile force.
