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 healthcare provider notes that a client is receiving lamivudine (Epivir). The healthcare provider determines that this medication has been prescribed to treat which of the following?

• A. Pancreatitis
• B. Pharyngitis
• C. Tonic-clonic seizures
• D. Human immunodeficiency virus (HIV) infection

Correct answer: D

Rationale: Lamivudine, known by the brand name Epivir, is an antiretroviral medication used in the treatment of human immunodeficiency virus (HIV) infection. This medication helps to inhibit the replication of HIV and improve the immune system function in individuals with HIV. Therefore, the correct answer is option D, Human immunodeficiency virus (HIV) infection.

3. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the client's teaching plan?

• A. Avoid taking folic acid supplements.
• B. Report any signs of infection immediately.
• C. Take the medication with a full meal.
• D. Limit fluid intake while on this medication.

Correct answer: B

Rationale: The correct instruction for the nurse to include in the client's teaching plan when taking methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the client more susceptible to infections. It is important for the client to promptly report any signs of infection to receive timely medical intervention. Choice A is incorrect because folic acid supplements are often recommended to reduce side effects of methotrexate. Choice C is incorrect as methotrexate is usually taken on an empty stomach unless the client experiences gastrointestinal upset. Choice D is incorrect as there is no need to limit fluid intake while on methotrexate; in fact, maintaining adequate fluid intake is important to prevent complications such as kidney damage.

4. The client with small cell lung cancer is being treated with etoposide (VePesid). The nurse assisting in caring for the client during its administration understands that which side effect is specifically associated with this medication?

• A. Alopecia
• B. Chest pain
• C. Pulmonary fibrosis
• D. Orthostatic hypotension

Correct answer: D

Rationale: The correct answer is 'D: Orthostatic hypotension.' Etoposide is associated with orthostatic hypotension, a sudden drop in blood pressure that can occur when transitioning from lying down to standing up. It is important for the nurse to monitor the client's blood pressure during the infusion to detect and manage this potential side effect.

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.
