1. A healthcare professional is preparing to administer Spironolactone to a client. Which of the following laboratory results should the professional review before administering this medication?

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

Correct answer: A

Rationale: When administering Spironolactone, it is essential to monitor the client's serum potassium levels because Spironolactone is a potassium-sparing diuretic. Monitoring potassium levels helps to detect hyperkalemia, a potential adverse effect of the medication.

2. What is the therapeutic action of Phenytoin?

A. Antidiabetic
B. Anticonvulsant
C. Mood stabilizer
D. Antianxiety agent

Correct answer: B

Rationale: Phenytoin is primarily used as an anticonvulsant to prevent and control seizures. It works by stabilizing electrical activity in the brain, making it effective in managing conditions like epilepsy. Antidiabetic medications are used to regulate blood sugar levels, mood stabilizers help manage mood disorders, and antianxiety agents are used to reduce anxiety symptoms, none of which are the primary therapeutic action of Phenytoin.

3. When a client is receiving treatment with methotrexate, which supplement should the nurse instruct the client to take?

A. Folic acid
B. Vitamin D
C. Calcium
D. Iron

Correct answer: A

Rationale: Folic acid supplementation is crucial for clients undergoing methotrexate treatment because methotrexate functions as a folic acid antagonist. By supplementing with folic acid, the risk of methotrexate toxicity can be minimized, improving the treatment's effectiveness and safety. Vitamin D, calcium, and iron are not specifically recommended in conjunction with methotrexate therapy and may not provide the same protective benefits as folic acid.

4. Which of the following conditions are not treated with Barbiturates?

A. Seizures
B. Hypotension
C. Insomnia
D. Anxiety

Correct answer: B

Rationale: Hypotension is not treated with barbiturates. Barbiturates are primarily used for treating seizures, insomnia, and anxiety, but they are not indicated for the treatment of hypotension.

5. A client is starting therapy with Metformin. Which of the following instructions should the nurse include?

A. Take this medication with your first bite of food.
B. Take this medication on an empty stomach.
C. Take this medication before bedtime.
D. Take this medication every other day.

Correct answer: A

Rationale: Metformin should be taken with meals to reduce gastrointestinal side effects and ensure better absorption. Instructing the client to take the medication with the first bite of food helps in achieving optimal effectiveness and minimizes the risk of side effects like nausea or upset stomach. Choice B is incorrect because taking Metformin on an empty stomach can lead to increased gastrointestinal side effects. Choice C is incorrect as there is no specific timing requirement for taking Metformin before bedtime. Choice D is incorrect as Metformin is usually taken daily, not every other day.
