HESI RN

1. Carbamazepine (Tegretol) is prescribed for a client with a diagnosis of psychomotor seizures. The nurse reviews the client's health history, knowing that this medication is contraindicated if which of the following disorders is present?

A. Headaches
B. Liver disease
C. Hypothyroidism
D. Diabetes mellitus

Correct answer: B

Rationale: Carbamazepine (Tegretol) is contraindicated in liver disease due to its potential to cause hepatic toxicity. Regular monitoring of liver function tests is necessary when using this medication to detect any signs of liver damage.

2. When is the best time for a client to take a daily dose of prednisone?

A. At noon
B. At bedtime
C. Early morning
D. Anytime, at the same time each day

Correct answer: C

Rationale: The correct time for a client to take a daily dose of prednisone is early morning. Corticosteroids like prednisone should be taken in the morning to mimic the body's natural hormone release pattern. This timing helps reduce the risk of disrupting the body's internal clock and minimizes the potential for insomnia or other sleep disturbances.

3. A healthcare provider has written a prescription for ranitidine (Zantac), once daily. When should the nurse schedule the medication?

A. At bedtime
B. After lunch
C. With supper
D. Before breakfast

Correct answer: A

Rationale: The correct answer is A: At bedtime. Ranitidine should be scheduled at bedtime because it provides a prolonged effect and offers the greatest protection of the gastric mucosa. Administering it at this time helps in managing nocturnal acid breakthrough and providing relief during the night.

4. A healthcare professional prepares to administer sodium polystyrene sulfonate (Kayexalate) to a client. Before administering the medication, the professional reviews the action of the medication and understands that it:

A. Releases bicarbonate in exchange for primarily sodium ions
B. Releases sodium ions in exchange for primarily potassium ions
C. Releases potassium ions in exchange for primarily sodium ions
D. Releases sodium ions in exchange for primarily bicarbonate ions

Correct answer: B

Rationale: Sodium polystyrene sulfonate, such as Kayexalate, is a cation exchange resin that functions by releasing sodium ions in exchange for primarily potassium ions. This medication is commonly used to treat hyperkalemia, a condition characterized by elevated levels of potassium in the blood.

5. A healthcare provider is preparing to administer a prescribed dose of digoxin (Lanoxin) to a client. Before administering the medication, the healthcare provider should:

A. Measure the client's blood pressure.
B. Check the client's heart rate.
C. Assess the client's respiratory rate.
D. Check the client's oxygen saturation level.

Correct answer: B

Rationale: Before administering digoxin (Lanoxin), the healthcare provider should check the client's heart rate. Monitoring the heart rate is crucial because if it is below 60 beats per minute, the medication should be withheld, and the healthcare provider must be informed. While blood pressure, respiratory rate, and oxygen saturation are essential assessments, they are not the primary focus before administering digoxin.
