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 community health nurse visits a client at home. Prednisone 10 mg orally daily has been prescribed for the client. The nurse reinforces teaching for the client about the medication. Which statement, if made by the client, indicates that further teaching is necessary?

• A. I can take aspirin or my antihistamine if I need it.
• B. I need to take the medication every day at the same time.
• C. I need to avoid coffee, tea, cola, and chocolate in my diet.
• D. If I gain more than 5 pounds a week, I will call my doctor.

Correct answer: A

Rationale: Aspirin and other over-the-counter medications should not be taken without consulting the health care provider (HCP). The client needs to take the medication at the same time every day and avoid caffeine-containing foods and fluids to prevent steroid-ulcer development.

3. When a client taking warfarin sodium (Coumadin) is prescribed ciprofloxacin (Cipro), the nurse should closely monitor the client for which potential effect of this drug interaction?

• A. Increased risk of bleeding
• B. Decreased warfarin effectiveness
• C. Increased risk of thrombosis
• D. Decreased ciprofloxacin effectiveness

Correct answer: A

Rationale: When ciprofloxacin (Cipro) is given with warfarin sodium (Coumadin), it can potentiate the effects of warfarin, leading to an increased risk of bleeding. Therefore, the nurse should closely monitor the client's INR levels and watch for signs of bleeding such as bruising, petechiae, or black tarry stools.

4. A client with hypertension is prescribed losartan (Cozaar). Which instruction should the nurse include in the teaching plan?

• A. Avoid foods high in potassium.
• B. Take the medication with grapefruit juice.
• C. Monitor blood pressure weekly.
• D. Report any swelling of the lips or face.

Correct answer: D

Rationale: The correct instruction for a client prescribed losartan (Cozaar) is to report any swelling of the lips or face. Losartan can cause angioedema, which is a serious side effect that requires immediate medical attention. Clients do not need to avoid potassium-rich foods unless specifically instructed by their healthcare provider. Taking the medication with grapefruit juice is not recommended as it can interact with certain medications. Additionally, monitoring blood pressure regularly is important, but it should not be limited to a weekly basis; blood pressure should be monitored as per the healthcare provider's recommendation.

5. A client receiving nitrofurantoin (Macrodantin) calls the health care provider's office complaining of side effects related to the medication. Which side effect indicates the need to stop treatment with this medication?

• A. Nausea
• B. Diarrhea
• C. Anorexia
• D. Cough and chest pain

Correct answer: D

Rationale: Pulmonary reactions such as cough and chest pain are serious side effects associated with nitrofurantoin that require immediate discontinuation of the medication to prevent potential severe respiratory complications.
