Nursing Elites

1. A client who is receiving digoxin (Lanoxin) daily has a serum potassium level of 3.0 mEq/L and is complaining of anorexia. A healthcare provider prescribes a digoxin level to rule out digoxin toxicity. A nurse checks the results, knowing that which of the following is the therapeutic serum level (range) for digoxin?

• A. 3 to 5 ng/mL
• B. 0.5 to 2 ng/mL
• C. 1.2 to 2.8 ng/mL
• D. 3.5 to 5.5 ng/mL

Correct answer: B

Rationale: The therapeutic serum level for digoxin ranges from 0.5 to 2 ng/mL. This range is considered optimal for therapeutic effects while minimizing the risk of toxicity. Levels above 2 ng/mL may lead to digoxin toxicity, which can manifest as anorexia among other symptoms. Therefore, the nurse should be vigilant in monitoring the digoxin levels to ensure the client's safety and therapeutic effectiveness of the medication.

2. A client is being educated about the use of levodopa-carbidopa (Sinemet) for Parkinson's disease. Which statement by the client indicates a need for further teaching?

• A. I should avoid taking the medication with a high-protein meal.
• B. I may experience dizziness when getting up quickly.
• C. I might notice a darkening of my urine.
• D. I should report any uncontrolled movements to my healthcare provider.

Correct answer: A

Rationale: The correct answer is A. Levodopa-carbidopa (Sinemet) should not be taken with a high-protein meal as protein can interfere with the absorption of the medication. It is recommended to take it on an empty stomach or with a light meal. Choices B, C, and D are accurate statements regarding potential side effects and actions to take while on levodopa-carbidopa therapy, indicating a good understanding by the client.

3. A client is receiving instructions from a healthcare provider about intranasal desmopressin acetate (DDAVP). The healthcare provider explains that which of the following is a side effect of the medication?

• A. Headache
• B. Vulval pain
• C. Runny nose
• D. Flushed skin

Correct answer: C

Rationale: Intranasal desmopressin can cause a runny or stuffy nose as a side effect due to its mode of administration through the nasal passages.

4. A client is to begin a 6-month course of therapy with isoniazid (INH). A nurse plans to teach the client to:

• A. Avoid drinking alcohol.
• B. Report yellow eyes or skin immediately.
• C. Avoid Swiss or aged cheeses.
• D. Avoid vitamin supplements during therapy.

Correct answer: B

Rationale: When a client is on isoniazid (INH) therapy, they should be instructed to report any signs of hepatitis, such as yellowing of the eyes or skin, immediately. Alcohol consumption should be avoided during INH therapy due to the risk of hepatotoxicity. Foods high in tyramine, such as Swiss or aged cheeses, should also be avoided to prevent adverse reactions. Additionally, while on INH therapy, it is essential to avoid vitamin supplements containing pyridoxine (vitamin B6) to prevent potential interactions.

5. The client with acute myelocytic leukemia is being treated with busulfan (Myleran). Which laboratory value should the nurse specifically monitor during treatment with this medication?

• A. Clotting time
• B. Uric acid level
• C. Potassium level
• D. Blood glucose level

Correct answer: B

Rationale: The correct answer is B, Uric acid level. Busulfan can cause an increase in uric acid levels, leading to hyperuricemia, renal stones, and acute renal failure. Monitoring uric acid levels is crucial to detect and manage potential complications associated with busulfan therapy.
