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. The nurse provides medication instructions to an older hypertensive client who is taking 20 mg of lisinopril (Prinivil, Zestril) orally daily. The nurse evaluates the need for further teaching when the client states which of the following?

• A. I can skip a dose once a week.
• B. I need to change my position slowly.
• C. I take the pill after breakfast each day.
• D. If I get a bad headache, I should call my doctor immediately.

Correct answer: A

Rationale: Lisinopril should be taken daily as prescribed and not skipped. Skipping doses can lead to ineffective treatment.

3. Atenolol hydrochloride (Tenormin) is prescribed for a hospitalized client. The nurse should perform which of the following as a priority action before administering the medication?

• A. Listen to the client's lung sounds.
• B. Check the client's blood pressure.
• C. Check the recent electrolyte levels.
• D. Assess the client for muscle weakness.

Correct answer: B

Rationale: Atenolol hydrochloride is a beta-blocker used to treat hypertension. Checking the client's blood pressure is crucial before administration.

4. A client is receiving dietary instructions from a nurse regarding warfarin sodium (Coumadin) therapy. The nurse advises the client to avoid which food item?

• A. Grapes
• B. Spinach
• C. Watermelon
• D. Cottage cheese

Correct answer: B

Rationale: The correct answer is B: Spinach. Spinach is high in vitamin K, which antagonizes the effects of warfarin sodium, an anticoagulant medication. Clients taking warfarin should avoid consuming foods rich in vitamin K, like spinach, to maintain the medication's effectiveness. Grapes (choice A), watermelon (choice C), and cottage cheese (choice D) do not interfere with the effects of warfarin, so they are safe for the client to consume while on warfarin therapy.

5. A client is prescribed amlodipine (Norvasc) for hypertension. Which side effect should the nurse instruct the client to report to the healthcare provider?

• A. Dizziness
• B. Constipation
• C. Peripheral edema
• D. Dry cough

Correct answer: C

Rationale: The correct answer is C, 'Peripheral edema.' Amlodipine (Norvasc) can cause peripheral edema, which is an accumulation of fluid in the extremities and should be reported to the healthcare provider. Dizziness and constipation are possible side effects of amlodipine but are generally less concerning. Dry cough is more commonly associated with ACE inhibitors, not calcium channel blockers like amlodipine.
