Correct Answer: A

Rationale: The correct answer is A: 'It can cause drowsiness.' Gabapentin is known to cause drowsiness, and clients should be warned about this side effect. Choice B is incorrect because gabapentin, like any medication, can have side effects. Choice C is incorrect because although gabapentin is used for pain management, it is not classified as a pain reliever. Choice D is incorrect because gabapentin should be taken as prescribed by the healthcare provider, and specific instructions regarding food intake should be provided based on individual needs.

Correct Answer: D

Rationale: Amiodarone is known to potentially affect liver function, potassium levels, and blood pressure. Monitoring all these parameters regularly is crucial to detect any adverse effects early on. Liver function tests are necessary as amiodarone can cause hepatotoxicity. Serum potassium levels should be monitored due to the risk of hypokalemia or hyperkalemia with amiodarone use. Blood pressure monitoring is essential as amiodarone can cause hypotension or hypertension. Choosing 'All of the above' is the correct answer because all these parameters should be monitored to ensure the client's safety and well-being. Monitoring only one or two of these parameters may lead to missing important signs of adverse effects.

Correct Answer: C

Rationale: The correct answer is to give enoxaparin in the abdomen. Enoxaparin is usually administered subcutaneously in the abdomen to avoid muscle irritation. Choice A is incorrect because enoxaparin should not be administered intramuscularly. Choice B is incorrect as monitoring APTT levels is not directly related to administering enoxaparin. Choice D is incorrect as enoxaparin should be administered slowly to prevent bruising or bleeding at the injection site.

Correct Answer: B

Rationale: The correct answer is B: 'Take the medication at the same time every day.' Clients should take digoxin at the same time each day to maintain consistent therapeutic levels, enhancing the drug's effectiveness and minimizing fluctuations in blood concentration. Choice A is incorrect because digoxin, as a medication, may actually help in controlling the heart rate. Choice C is incorrect as digoxin should never be stopped abruptly due to the risk of rebound effects and worsening of the condition. Choice D is unrelated to digoxin therapy, as it is more relevant to medications like potassium-sparing diuretics.

Correct Answer: B

Rationale: The correct answer is to monitor for headaches when taking sildenafil. This medication can cause headaches and other side effects, so it is crucial to inform clients about these potential adverse reactions. Choice A is incorrect because sildenafil should not be taken with nitrates due to the risk of severe hypotension. Choice C is incorrect as sildenafil is a prescription medication, not an over-the-counter one. Choice D is incorrect because sildenafil, like any medication, can have side effects that should be discussed with the client.
