Nursing Elites

1. 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.

2. 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.

3. A nurse is caring for a client who has been taking isoniazid and rifampin for 3 weeks for the treatment of active pulmonary tuberculosis (TB). The client reports his urine is an orange color. Which of the following statements should the nurse make?

• A. Stop taking the isoniazid for 3 days and the discoloration should go away.
• B. Rifampin can turn body fluids orange.
• C. I'll make an appointment for you to see the provider this afternoon.
• D. Isoniazid can cause bladder irritation.

Correct answer: B

Rationale: The correct answer is B: 'Rifampin can turn body fluids orange.' Rifampin is known to cause orange discoloration of body fluids, including urine. This side effect is harmless and does not indicate a need to stop the medication. Choice A is incorrect because stopping isoniazid will not resolve the orange urine discoloration caused by rifampin. Choice C is unnecessary at this point since the orange urine is a known side effect of rifampin and does not require an urgent provider visit. Choice D is incorrect because bladder irritation is not typically associated with isoniazid.

4. A nurse is preparing to administer iron dextran IV to a client. Which of the following actions should the nurse plan to take?

• A. Administer a small test dose before giving the full dose
• B. Infuse the medication over 30 seconds
• C. Monitor client closely for hypertension
• D. Administer cyanocobalamin as an antidote if toxicity occurs

Correct answer: A

Rationale: The correct action the nurse should plan to take when preparing to administer iron dextran IV is to administer a small test dose before giving the full dose. This is done to assess for any allergic reactions that the client may have to the medication. Choice B is incorrect because iron dextran should be infused slowly over a longer period, typically over 1-2 hours to reduce the risk of adverse reactions. Choice C is incorrect because iron dextran administration is more commonly associated with hypotension rather than hypertension. Choice D is incorrect because cyanocobalamin is not used as an antidote for iron dextran toxicity; instead, treatment for iron toxicity may involve supportive care, chelation therapy, or in severe cases, iron antidotes like deferoxamine.

5. 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.
