Nursing Elites

1. A client with portosystemic encephalopathy is receiving oral lactulose (Chronulac) daily. The nurse assesses which of the following to determine medication effectiveness?

• A. Lung sounds
• B. Blood pressure
• C. Blood ammonia level
• D. Serum potassium level

Correct answer: C

Rationale: In portosystemic encephalopathy, the liver's ability to detoxify ammonia is impaired, leading to elevated blood ammonia levels, which can cause neurological symptoms such as encephalopathy. Lactulose is given to reduce ammonia levels by promoting its excretion through the bowel. Therefore, assessing the blood ammonia level is crucial to determine the effectiveness of lactulose therapy in managing portosystemic encephalopathy.

2. 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.

3. A histamine (H2)-receptor antagonist will be prescribed for a client. The nurse understands that which medications are H2-receptor antagonists? Select one that doesn't apply.

• A. Nizatidine (Axid)
• B. Ranitidine (Zantac)
• C. Famotidine (Pepcid)
• D. Ibuprofen (Motrin)

Correct answer: D

Rationale: H2-receptor antagonists like Nizatidine, Ranitidine, and Famotidine are used to suppress gastric acid secretion, relieve heartburn symptoms, and prevent complications of peptic ulcer disease. Ibuprofen, on the other hand, is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for pain relief and inflammation, but it is not an H2-receptor antagonist. It is essential to differentiate between these medication classes to ensure appropriate treatment for gastrointestinal conditions.

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 who has begun taking fosinopril (Monopril) is very distressed, telling the nurse that he cannot taste food normally since beginning the medication 2 weeks ago. The nurse provides the best support to the client by:

• A. Telling the client not to take the medication with food
• B. Suggesting that the client taper the dose until taste returns to normal
• C. Informing the client that impaired taste is expected and generally disappears in 2 to 3 months
• D. Requesting that the health care provider (HCP) change the prescription to another brand of angiotensin-converting enzyme (ACE) inhibitor

Correct answer: C

Rationale: The correct answer is to inform the client that impaired taste is an expected side effect of ACE inhibitors like fosinopril, such as Monopril, and typically resolves within 2 to 3 months. It is essential for the nurse to offer reassurance and education to the client about this common side effect to alleviate distress and encourage compliance with the medication regimen.
