Nursing Elites

1. A client at 28 weeks of gestation is experiencing preterm labor. Which of the following medications should the nurse plan to administer?

• A. Oxytocin
• B. Nifedipine
• C. Dinoprostone
• D. Misoprostol

Correct answer: B

Rationale: Nifedipine is the correct choice because it is a calcium channel blocker that helps relax the uterus and stop preterm labor. Oxytocin (Choice A) is used to induce labor, not to stop preterm labor. Dinoprostone (Choice C) and Misoprostol (Choice D) are prostaglandins used to induce labor and ripen the cervix, not to stop preterm labor.

2. A nurse is preparing to administer furosemide 4 mg/kg/day PO divided into 2 equal doses daily to a toddler who weighs 22 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number)

• A. 20 mg
• B. 15 mg
• C. 10 mg
• D. 30 mg

Correct answer: A

Rationale: To calculate the dosage per dose, first, convert the toddler's weight from pounds to kilograms: 22 lb / 2.2 = 10 kg. Then, multiply the weight by the dosage: 4 mg × 10 kg = 40 mg/day. Since this total daily dose is divided into 2 equal doses, the nurse should administer 20 mg per dose. Therefore, the correct answer is 20 mg. Choice B (15 mg) is incorrect because it does not account for the correct weight conversion and dosage calculation. Choice C (10 mg) is incorrect as it only considers the weight conversion but doesn't multiply it by the dosage. Choice D (30 mg) is incorrect as it miscalculates the dosage by not dividing the total daily dose into 2 equal parts.

3. 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.

4. 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.

5. A nurse is preparing to administer prochlorperazine 2.5 mg IV. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth)

• A. 0.5 mL
• B. 0.005 mL
• C. 0.05 mL
• D. 5 mL

Correct answer: A

Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.
