Nursing Elites

1. 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.

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 lactated Ringer's (LR) 1,000 mL IV to infuse over 8 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number).

• A. 21 gtt/min
• B. 20 gtt/min
• C. 25 gtt/min
• D. 18 gtt/min

Correct answer: A

Rationale: To calculate the IV infusion rate in gtt/min: 1000 mL / 480 min × 10 gtt/mL = 20.83 ≈ 21 gtt/min. Therefore, the correct answer is A. Choice B (20 gtt/min) is incorrect because the calculation results in 20.83 gtt/min, rounded to 21. Choices C (25 gtt/min) and D (18 gtt/min) are incorrect as they are not the closest whole number approximation to the calculated value.

4. A client with chronic kidney failure and an AV fistula for hemodialysis is prescribed epoetin alfa. Which of the following therapeutic effects should the nurse include in the teaching?

• A. Reduces blood pressure
• B. Inhibits clotting of fistula
• C. Promotes RBC production
• D. Stimulates growth of neutrophils

Correct answer: C

Rationale: The correct answer is C: Promotes RBC production. Epoetin alfa stimulates erythropoiesis (red blood cell production) to treat anemia associated with chronic kidney failure. This helps in increasing the hemoglobin levels and improving oxygen-carrying capacity. Choices A, B, and D are incorrect as epoetin alfa does not have direct effects on reducing blood pressure, inhibiting clotting of the fistula, or stimulating the growth of neutrophils.

5. A nurse is caring for a client who has a new prescription for amphotericin B. The nurse should plan to monitor the client for which of the following adverse effects?

• A. Hyperkalemia
• B. Hypertension
• C. Constipation
• D. Nephrotoxicity

Correct answer: D

Rationale: Correct. Amphotericin B is known for its nephrotoxicity, which can lead to kidney damage. Monitoring kidney function is crucial to detect any signs of nephrotoxicity early. Choices A, B, and C are incorrect because hyperkalemia, hypertension, and constipation are not typically associated with amphotericin B use. Therefore, the nurse should focus on monitoring for nephrotoxicity.
