1. A client has a new prescription for Atorvastatin. Which of the following instructions should the nurse include?

A. Avoid drinking grapefruit juice.
B. Take the medication with your evening meal.
C. Increase your intake of leafy green vegetables.
D. Stop taking the medication if you experience muscle pain.

Correct answer: A

Rationale: The correct answer is A: 'Avoid drinking grapefruit juice.' Grapefruit juice should be avoided when taking Atorvastatin because it can increase the blood levels of the medication, potentially leading to a higher risk of adverse effects like muscle pain and liver damage. It is important to follow this instruction to ensure the safe and effective use of Atorvastatin. Choices B, C, and D are incorrect. Taking Atorvastatin with food, specifically a low-fat meal, is recommended, but it is not necessary to specify the evening meal. While increasing intake of leafy green vegetables is generally beneficial for health, it is not a specific instruction for Atorvastatin. Lastly, stopping the medication if one experiences muscle pain is not advisable without consulting a healthcare provider, as muscle pain can be a symptom of a serious side effect of Atorvastatin that requires medical attention.

2. A client is prescribed Propylthiouracil (PTU) for the treatment of Graves' disease. Which adverse effect should the client be instructed to report?

A. Sore throat.
B. Drowsiness.
C. Urinary retention.
D. Heat intolerance.

Correct answer: A

Rationale: The correct answer is A: Sore throat. A sore throat and fever can indicate agranulocytosis, a serious adverse effect of PTU that can lead to a decreased white blood cell count. This condition requires immediate medical attention to prevent complications. Choice B, drowsiness, is not typically associated with PTU and is not a common adverse effect that needs to be reported. Choice C, urinary retention, is not a typical adverse effect of PTU; therefore, it is not the correct answer. Choice D, heat intolerance, is a symptom commonly seen in hyperthyroidism, which PTU is used to treat, so it is not an adverse effect that needs to be specifically reported.

3. A client has a new prescription for Lisinopril. Which of the following laboratory values should be monitored?

A. Serum potassium
B. Serum sodium
C. Serum calcium
D. Serum magnesium

Correct answer: A

Rationale: Corrected Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing potassium excretion through the kidneys. Monitoring serum potassium levels is crucial to detect hyperkalemia early and prevent adverse effects such as cardiac arrhythmias. Choices B, C, and D are incorrect because Lisinopril is not known to significantly impact sodium, calcium, or magnesium levels in the same way it affects potassium levels.

4. What is the therapeutic class of Valproate?

A. Anticoagulant
B. Antianxiety, benzodiazepines
C. Anticonvulsant, vascular headache suppressant
D. Mood stabilizer

Correct answer: C

Rationale: Valproate belongs to the therapeutic class of anticonvulsants. It is primarily used to manage seizures but is also effective in treating vascular headaches. Therefore, it is not classified as an anticoagulant, antianxiety medication, or mood stabilizer. Option A, anticoagulant, is incorrect as valproate does not have anticoagulant properties. Option B, antianxiety benzodiazepines, is incorrect as valproate is not primarily used to treat anxiety disorders with benzodiazepines. Option D, mood stabilizer, is incorrect as valproate is not classified as a mood stabilizer, although it can be used in some cases for mood disorders, its primary therapeutic class is anticonvulsant.

5. A drug ending in the suffix (tidine) is considered a ______.

A. Antidepressant
B. Protease inhibitor
C. Beta antagonist
D. H antagonist

Correct answer: D

Rationale: Drugs ending in -tidine are histamine (H2) receptor antagonists, which block the action of histamine at the H2 receptors, commonly used to reduce stomach acid production. Therefore, the correct answer is an 'H antagonist.' It is essential to be familiar with drug suffixes as they can provide clues to the drug's class and function.
