Cardiovascular Practice Questions Questions
Question 1 of 5
Adverse reactions from non-cardio-selective beta blockers include which of the following? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Increases heart rate. Non-cardio-selective beta blockers block beta-1 and beta-2 receptors, leading to unopposed alpha receptor activity, which can result in increased heart rate. Choice A is incorrect because beta blockers typically lower blood pressure. Choice C is incorrect as beta blockers can cause sinus bradycardia, not increase it. Choice D is incorrect because non-cardio-selective beta blockers can exacerbate asthma due to blocking beta-2 receptors, not because they increase heart rate.
Question 2 of 5
The client has developed neutropenia from a medication. What medication might this be?
Correct Answer: B
Rationale: Neutropenia is a known side effect of captopril, an ACE inhibitor. Captopril can lead to a decrease in white blood cells, including neutrophils. Metoprolol, Lisinopril, and Guanfacine are not associated with causing neutropenia. Metoprolol is a beta-blocker, Lisinopril is another ACE inhibitor, and Guanfacine is an alpha-2 adrenergic agonist. It is crucial to identify captopril as the likely medication causing neutropenia based on its pharmacological profile and known adverse effects.
Question 3 of 5
The client is on low molecular weight heparin. A priority nursing intervention is what?
Correct Answer: C
Rationale: The correct answer is C: Monitor for hemorrhage. This is a priority nursing intervention because low molecular weight heparin can increase the risk of bleeding. Monitoring for signs of bleeding such as bruising, petechiae, or blood in stool is crucial to prevent serious complications. A: Monitoring heparin levels is not necessary for low molecular weight heparin as it does not require routine monitoring. B: Monitoring aPTT is not necessary for low molecular weight heparin as it primarily affects unfractionated heparin levels. D: Monitoring blood sugar is unrelated to low molecular weight heparin therapy and is not a priority intervention. In summary, monitoring for hemorrhage is essential to ensure patient safety when on low molecular weight heparin, making it the correct priority nursing intervention.
Question 4 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: The correct answer is C. Thrombotic thrombocytopenic purpura (TTP) is a rare but serious adverse effect associated with ADP receptor blockers, characterized by microangiopathic hemolytic anemia, thrombocytopenia, fever, renal dysfunction, and neurological abnormalities. The development of hemorrhaging and low platelet count in this client suggests TTP, not a typical reaction to ADP receptor blockers (choice A), not necessarily due to concomitant aspirin use (choice B), and not necessarily indicative of taking too much of the medication (choice D). TTP requires immediate medical intervention to prevent serious complications.
Question 5 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 due to potential additive effects on muscle toxicity. 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 typically have significant drug-drug interactions with niacin. It is important to be cautious when combining niacin with statins to minimize the risk of adverse effects.
