1. A client is taking phenytoin (Dilantin) for seizure control, and a sample for a serum drug level is drawn. Which of the following indicates a therapeutic serum drug range?

Correct answer: B

Rationale: The correct therapeutic serum drug level range for phenytoin (Dilantin) is 10 to 20 mcg/mL. This range is considered optimal for seizure control while minimizing the risk of toxicity. Monitoring drug levels helps ensure that the client is within the therapeutic range for effective treatment.

2. A child is hospitalized with a diagnosis of lead poisoning. The healthcare provider assisting in caring for the child would prepare to assist in administering which of the following medications?

Correct answer: D

Rationale: Dimercaprol (BAL in Oil) is a chelating agent indicated for lead poisoning. It works by binding to lead and facilitating its removal from the body. Activated charcoal is used for certain types of poisoning by adsorbing toxins, while sodium bicarbonate can be used to treat acidosis. Syrup of ipecac is no longer recommended for poison treatment due to potential risks.

3. A client has been prescribed cyclosporine (Sandimmune). Which food item should the client avoid based on the medication's interaction?

Correct answer: C

Rationale: Grapefruit juice should be avoided when taking cyclosporine because it inhibits the metabolism of the medication, leading to increased blood levels and a higher risk of toxicity. It is important for the client to follow this dietary instruction to ensure the safe and effective use of cyclosporine.

4. A healthcare professional is planning to administer amlodipine (Norvasc) to a client. The healthcare professional plans to check which of the following before giving the medication?

Correct answer: B

Rationale: Before administering amlodipine, it is important to check the client's blood pressure and heart rate. Amlodipine is known to lower blood pressure and heart rate as part of its mechanism of action. Monitoring these vital signs helps ensure the safety of the client and allows for appropriate assessment of the medication's effects post-administration.

5. Salicylic acid is prescribed for a client with a diagnosis of psoriasis. The nurse monitors the client, knowing that which of the following would indicate the presence of systemic toxicity from this medication?

Correct answer: A

Rationale: The correct answer is A: Tinnitus. Salicylic acid can lead to systemic toxicity, known as salicylism, which may manifest with symptoms like tinnitus, dizziness, hyperventilation, and mental disturbances. Tinnitus is a common early sign of salicylism and should be monitored closely by the nurse to prevent further complications.
