Nursing Elites

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?

• A. 5 to 10 mcg/mL
• B. 10 to 20 mcg/mL
• C. 20 to 30 mcg/mL
• D. 30 to 40 mcg/mL

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 client has been taking isoniazid (INH) for 2 months. The client complains to a nurse about numbness, paresthesias, and tingling in the extremities. The nurse interprets that the client is experiencing:

• A. Hypercalcemia
• B. Peripheral neuritis
• C. Small blood vessel spasm
• D. Impaired peripheral circulation

Correct answer: B

Rationale: The client's symptoms of numbness, paresthesias, and tingling in the extremities indicate peripheral neuritis, a common side effect of isoniazid (INH). This condition can be managed by supplementing with pyridoxine (vitamin B6) to minimize the symptoms.

3. A client is receiving intravenous gentamicin (Garamycin). Which of the following findings should prompt the nurse to notify the healthcare provider immediately?

• A. Nausea
• B. Hearing loss
• C. Headache
• D. Diarrhea

Correct answer: B

Rationale: Gentamicin (Garamycin) is an aminoglycoside antibiotic known to cause ototoxicity, which can manifest as hearing loss. Hearing loss is a serious adverse effect that should be reported promptly to the healthcare provider to prevent further complications or adjust the treatment regimen. Nausea, headache, and diarrhea are common side effects of gentamicin but are not as severe or urgent as hearing loss in this context.

4. A client is prescribed allopurinol (Zyloprim) for chronic gout. Which instruction should the nurse include in the teaching plan?

• A. Take the medication with a full glass of water.
• B. Increase your intake of purine-rich foods.
• C. Stop taking the medication if you experience a gout attack.
• D. Take the medication with or without food.

Correct answer: A

Rationale: The correct instruction for a client prescribed allopurinol (Zyloprim) for chronic gout is to take the medication with a full glass of water. This helps prevent kidney stones which can be a side effect of the medication. It is important for the client to avoid purine-rich foods to help manage gout symptoms. They should continue taking the medication even during a gout attack as prescribed by the healthcare provider. Allopurinol can be taken with or without food, so there is no need to take it on an empty stomach. Therefore, option A is the correct choice. Options B, C, and D are incorrect as increasing purine-rich foods is not recommended, stopping the medication during a gout attack is not advised, and allopurinol can be taken with or without food.

5. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied:

• A. Immediately before swimming
• B. 15 minutes before exposure to the sun
• C. Immediately before exposure to the sun
• D. At least 30 minutes before exposure to the sun

Correct answer: D

Rationale: Chemical sunscreens are most effective when applied at least 30 minutes before exposure to the sun to allow them to penetrate the skin and provide optimal protection. Applying sunscreen immediately before swimming (Choice A) or immediately before exposure to the sun (Choice C) may not provide sufficient time for the sunscreen to be absorbed and offer proper protection. Applying sunscreen 15 minutes before sun exposure (Choice B) is also not ideal as it may not allow enough time for the sunscreen to work effectively. Therefore, the correct answer is to apply chemical sunscreen at least 30 minutes before exposure to the sun to ensure it can be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.
