1. A client is prescribed Lithium. Which of the following laboratory values should be monitored to assess for potential toxicity?

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

Correct answer: B

Rationale: When a client is prescribed Lithium, monitoring serum lithium levels is crucial to ensure they remain within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels helps prevent adverse effects associated with lithium toxicity, such as nausea, vomiting, diarrhea, tremors, and confusion.

2. Which of the following is not directly related to drug toxicity of Nitroglycerin?

A. Headaches
B. Tachycardia
C. Dizziness
D. Projectile vomiting

Correct answer: D

Rationale: Headaches, tachycardia, and dizziness are common side effects of nitroglycerin due to its vasodilatory properties. Projectile vomiting is not typically associated with nitroglycerin toxicity, making it the correct answer. Therefore, option D is the correct choice.

3. 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.

4. Which medication is contraindicated with Nitroglycerin?

A. Hydrochloroquine
B. Methylprednisolone
C. Phenazopyridine
D. Erectile dysfunction drugs

Correct answer: D

Rationale: The correct answer is D: Erectile dysfunction drugs. Erectile dysfunction drugs are contraindicated with Nitroglycerin because they can potentiate the hypotensive effects of Nitroglycerin, leading to severe hypotension. Choices A, B, and C are incorrect because they are not known to have significant interactions with Nitroglycerin.

5. A client with angina is seeking a prescription for sildenafil to manage erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?

A. Aspirin
B. Isosorbide
C. Clopidogrel
D. Atorvastatin

Correct answer: B

Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.
