Pharmacology of Drugs Acting on Cardiovascular System Questions
Question 1 of 5
The health care provider is planning to discontinue a patient’s beta blocker. Which instruction will the nurse give the patient regarding the beta blocker?
Correct Answer: B
Rationale: The correct answer is B because abruptly stopping a beta blocker can lead to rebound hypertension, angina, or arrhythmias due to sudden withdrawal of the medication. Tapering down the dose gradually allows the body to adjust and reduces the risk of adverse effects. Choice A is incorrect because abruptly stopping a beta blocker can be harmful. Choice C is incorrect as it suggests maintaining the dose while taking another antianginal medication, which may not be necessary. Choice D is incorrect as halving the dose without proper guidance can lead to inadequate therapeutic effect or withdrawal symptoms.
Question 2 of 5
A patient who is prescribed an antidepressant medication tells a nurse, “I’ve been getting dizzy in the morning when I wake up ever since I started this drug. Do you think I should stop taking it?” Which communication would reflect the most therapeutic nursing intervention on the basis of the patient’s problem?
Correct Answer: A
Rationale: The correct answer is A because it provides the patient with appropriate education on how to manage the dizziness related to orthostatic hypotension, a common side effect of antidepressants. Changing positions slowly and dangling feet can prevent sudden drops in blood pressure upon standing. Choice B is incorrect as stopping driving may not be necessary, and napping may not directly address the dizziness. Choice C is incorrect as it dismisses the patient's symptoms and does not provide practical advice on managing the dizziness. Choice D is incorrect as abruptly stopping the medication without consulting the doctor can be dangerous and does not address the underlying issue of orthostatic hypotension.
Question 3 of 5
An 18-year-old basketball player fell and twisted his ankle during a game. The nurse will expect to administer which type of analgesic?
Correct Answer: D
Rationale: The correct answer is D: Nonopioid analgesic, such as indomethacin (Indocin). Given the ankle injury, nonopioid analgesics like indomethacin are appropriate for managing pain as they target inflammation and reduce pain without the risk of opioid-related side effects. Synthetic opioids (A) and opium alkaloids (B) are not typically indicated for mild to moderate pain like an ankle twist. Opioid antagonists (C) like naloxone are used to reverse opioid overdose, not for pain relief. In this case, the nonopioid analgesic is the most suitable choice for managing the player's pain effectively.
Question 4 of 5
The nurse is reviewing the food choices of a patient who is taking a monoamine oxidase inhibitor (MAOI). Which food choice would indicate the need for additional teaching?
Correct Answer: C
Rationale: The correct answer is C: Salami and Swiss cheese sandwich. This is because salami and Swiss cheese are high in tyramine, which can cause a hypertensive crisis in patients taking MAOIs due to their inhibitory effect on monoamine oxidase. Orange juice (A) does not contain tyramine. Fried eggs over-easy (B) and biscuits with honey (D) are also safe choices as they do not contain high levels of tyramine. Therefore, the need for additional teaching is indicated by the selection of foods high in tyramine like salami and Swiss cheese.
Question 5 of 5
A patient will be discharged on quinidine sulfate (Quinidex) extended-release tablets for the treatment of ventricular ectopy. The nurse will include which information in the teaching plan?
Correct Answer: B
Rationale: The correct answer is B: Signs of cinchonism, such as tinnitus, loss of hearing, or slight blurring of vision, may occur. Cinchonism is a potential side effect of quinidine sulfate, characterized by symptoms like tinnitus, loss of hearing, and blurred vision. It is essential for the nurse to educate the patient about these potential adverse effects to ensure early recognition and prompt reporting to the healthcare provider. This information is crucial for monitoring the patient's response to the medication and preventing further complications. Incorrect choices: A: The medication should not be stopped abruptly, and it is important to complete the prescribed course even if symptoms subside to prevent recurrence. C: While photosensitivity can be a side effect of some medications, it is not specifically associated with quinidine sulfate. It is not a priority teaching point for this medication. D: Seeing the tablet in the stool does not necessarily indicate treatment failure or danger. It is more likely due to the extended
