Nursing Elites

1. 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.

2. A nurse is providing teaching to a group of new parents about medications. The nurse should include that aspirin is contraindicated for children who have a viral infection due to the risk of developing which of the following adverse effects?

• A. Reye's syndrome
• B. Visual disturbances
• C. Diabetes mellitus
• D. Wilms' tumor

Correct answer: A

Rationale: The correct answer is A: Reye's syndrome. Aspirin use in children with viral infections has been associated with Reye's syndrome, a serious condition that causes swelling in the liver and brain. Visual disturbances (choice B) are not typically associated with aspirin use in children with viral infections. Diabetes mellitus (choice C) and Wilms' tumor (choice D) are not adverse effects of aspirin use in this context.

3. 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.

4. A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include that a severe allergy to which of the following medications is a contraindication to ceftriaxone?

• A. Gentamicin
• B. Clindamycin
• C. Piperacillin
• D. Sulfamethoxazole-trimethoprim

Correct answer: C

Rationale: The correct answer is C. Ceftriaxone, a cephalosporin antibiotic, has a cross-sensitivity with penicillin antibiotics like piperacillin. Therefore, a severe allergy to penicillin or penicillin-related antibiotics would be a contraindication to ceftriaxone. Choices A, B, and D are incorrect because they are not associated with a known cross-sensitivity with ceftriaxone.

5. A nurse is preparing to administer ampicillin 500 mg in 50 ml of dextrose 5% in water (D5W) to infuse over 15 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver? (Round to the nearest whole number)

• A. 33 gtt/min
• B. 66 gtt/min
• C. 10 gtt/min
• D. 14 gtt/min

Correct answer: A

Rationale: To calculate the IV flow rate, you multiply the drop factor (10 gtt/mL) by the volume to be infused per minute (50 mL / 15 min). This gives you 10 gtt/mL × 50 mL / 15 min = 33.33. Rounding to the nearest whole number, the nurse should set the manual IV infusion to deliver 33 gtt/min. Choice B (66 gtt/min) is incorrect as it is the result of doubling the correct answer. Choice C (10 gtt/min) is incorrect as it only considers the drop factor without accounting for the volume to be infused. Choice D (14 gtt/min) is incorrect as it miscalculates the infusion rate based on the given information.
