Nursing Elites

1. A client with cirrhosis is about to receive a dose of lactulose. The client questions the need for the medication, stating they are not constipated. The nurse should explain that lactulose is used in cirrhosis to reduce levels of which component in the bloodstream?

• A. Glucose
• B. Ammonia
• C. Potassium
• D. Bicarbonate

Correct answer: B

Rationale: Lactulose is administered to clients with cirrhosis to lower blood ammonia levels, thus aiding in the prevention of hepatic encephalopathy. Elevated ammonia levels in cirrhosis can lead to cognitive impairment and hepatic encephalopathy. Therefore, the correct answer is B (Ammonia). Glucose (Choice A) is not the component targeted by lactulose in cirrhosis. Potassium (Choice C) and Bicarbonate (Choice D) are not directly affected by lactulose administration in cirrhosis.

2. A healthcare professional is preparing to administer morphine 4 mg IV to a client. Available is morphine 10 mg/mL. How many mL should the healthcare professional administer?

• A. 0.2 mL
• B. 0.4 mL
• C. 0.6 mL
• D. 0.8 mL

Correct answer: B

Rationale: To administer 4 mg from a solution of 10 mg/mL, the healthcare professional should administer 0.4 mL. The calculation is done by dividing the desired dose (4 mg) by the concentration of the solution (10 mg/mL), which equals 0.4 mL. Choice A (0.2 mL) is incorrect because it is half of the correct calculation. Choice C (0.6 mL) is incorrect because it is 50% more than the correct calculation. Choice D (0.8 mL) is incorrect because it exceeds the correct calculation.

3. What is one therapeutic use for nitroglycerin?

• A. Relief or prevention of anginal attacks
• B. Diuresis and mobilization of excess fluid
• C. Decreasing nausea and vomiting
• D. Relief of anxiety

Correct answer: A

Rationale: Nitroglycerin is primarily used for the relief or prevention of anginal attacks. It works by dilating blood vessels, increasing blood flow and oxygen to the heart muscle, thereby relieving chest pain caused by angina. The medication is not indicated for diuresis, antiemetic effects, or anxiety relief. Therefore, choices B, C, and D are incorrect as they do not reflect the therapeutic use of nitroglycerin.

4. A client is receiving epoetin alfa to treat anemia. Which of the following findings should the nurse monitor?

• A. Leukocytosis
• B. Hypertension
• C. Hyperkalemia
• D. Fever

Correct answer: B

Rationale: The nurse should monitor the client for hypertension when receiving epoetin alfa. Epoetin alfa stimulates red blood cell production, which can lead to increased blood pressure. Monitoring blood pressure is crucial to detect and manage hypertension promptly. Leukocytosis refers to an increased white blood cell count and is not directly related to epoetin alfa treatment. Hyperkalemia is an elevated potassium level, which is not a common adverse effect of epoetin alfa. Fever is not a typical finding associated with epoetin alfa therapy.

5. When should a patient taking omeprazole be administered the medication?

• A. Before bedtime
• B. After dinner
• C. In the morning on an empty stomach
• D. With the patient's lunch meal

Correct answer: C

Rationale: Omeprazole should be administered in the morning on an empty stomach to maximize its effectiveness. This timing is important as omeprazole works best when taken before a meal to inhibit acid production by the stomach. Taking it on an empty stomach in the morning allows the medication to be absorbed efficiently and provides optimal therapeutic effects throughout the day. Choices A, B, and D are incorrect because taking omeprazole before bedtime, after dinner, or with lunch may not allow the medication to work effectively as it requires an empty stomach for better absorption and action.
