Nursing Elites

1. A nurse is providing teaching to a client who has cirrhosis and a new prescription for lactulose. The nurse should instruct the client that lactulose has which of the following therapeutic effects?

• A. Increases blood pressure
• B. Prevents esophageal bleeding
• C. Decreases heart rate
• D. Reduces ammonia levels

Correct answer: D

Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.

2. A nurse is administering subcutaneous heparin to a client who is at risk for deep vein thrombosis. Which of the following actions should the nurse take?

• A. Administer the medication into the client's abdomen.
• B. Inject the medication into a muscle.
• C. Massage the site after administering the medication.
• D. Use a 22-gauge needle to administer the medication.

Correct answer: A

Rationale: Heparin is best absorbed and less likely to cause hematomas when administered into subcutaneous tissue, specifically the abdomen, which is a common site for subcutaneous injections. Injecting heparin into a muscle (Choice B) is incorrect as it should be administered subcutaneously. Massaging the site after administering the medication (Choice C) is contraindicated as it can cause tissue damage or bruising. Using a 22-gauge needle (Choice D) is not recommended for subcutaneous injections of heparin; a smaller needle size such as 25-26 gauge is preferred for subcutaneous administration.

3. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)

• A. 0.8 mL
• B. 0.9 mL
• C. 10.0 mL
• D. 98.0 mL

Correct answer: A

Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.

4. A nurse is preparing to administer an enteral tube feeding through an NG tube at 250 mL over 4 hr. The nurse should set the pump to deliver how many mL/hr? (Round the answer to the nearest whole number)

• A. 63 mL/hr
• B. 36 mL/hr
• C. 78 mL/hr
• D. 90 mL/hr

Correct answer: A

Rationale: To calculate the rate for the enteral tube feeding, divide the total volume by the total time: 250 mL / 4 hr = 62.5 ≈ 63 mL/hr. Therefore, the nurse should set the pump to deliver 63 mL/hr. Choices B, C, and D are incorrect as they do not match the correct calculation result. B is too low, C is too high, and D is also too high based on the correct calculation.

5. A nurse on a medical unit is preparing to administer alendronate 40 mg PO for an older adult client who has Paget's disease of the bone. Which of the following actions should be the nurse's priority?

• A. Administer the medication to the client before breakfast in the morning.
• B. Assist the client to a chair before administering the medication.
• C. Give the medication to the client with water rather than milk.
• D. Educate the client on how to take the medication at home.

Correct answer: A

Rationale: The correct answer is to administer the medication to the client before breakfast in the morning. Alendronate should be taken on an empty stomach before breakfast to ensure optimal absorption. Choice B is incorrect because assisting the client to a chair is not directly related to the administration of alendronate. Choice C is incorrect as there is no specific requirement to avoid taking alendronate with milk. Choice D is also incorrect as the priority at this moment is the correct administration of the medication in the hospital setting.
