Nursing Elites

1. 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.

2. A nurse is planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. The amount available is chlorothiazide oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose? (Round to the nearest tenth)

• A. 2.6 mL
• B. 2.63 mL
• C. 2.7 mL
• D. 2.2 mL

Correct answer: A

Rationale: To find the dose per administration, first convert the toddler's weight to kg: 28.6 lb ÷ 2.2 = 13 kg. Then calculate the total daily dose: 20 mg/kg × 13 kg = 260 mg/day. Since it is divided into two doses, each dose is 130 mg. The concentration of the oral suspension is 250 mg/5 mL = 50 mg/mL. Therefore, to find the volume needed per dose, divide the dose by the concentration: 130 mg ÷ 50 mg/mL = 2.6 mL per dose. Hence, the nurse should administer 2.6 mL per dose. Choices B, C, and D are incorrect as they do not accurately calculate the dosage of chlorothiazide needed per dose based on the toddler's weight and the concentration of the oral suspension.

3. A nurse is caring for a client who has a prescription for chlorothiazide to treat hypertension. The nurse should plan to monitor the client for which of the following adverse effects?

• A. Thrombophlebitis
• B. Hyperactive reflexes
• C. Muscle weakness
• D. Hypoglycemia

Correct answer: C

Rationale: The correct answer is C: Muscle weakness. Chlorothiazide, a thiazide diuretic, can lead to hypokalemia, which can cause muscle weakness. Thrombophlebitis (choice A) is not typically associated with chlorothiazide use. Hyperactive reflexes (choice B) and hypoglycemia (choice D) are also not commonly linked to this medication. Therefore, monitoring for muscle weakness is crucial when a client is prescribed chlorothiazide.

4. 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.

5. A client with a severe urinary tract infection (UTI) asks why both ciprofloxacin and phenazopyridine are needed. Which of the following responses should the nurse make?

• A. Phenazopyridine decreases adverse effects of ciprofloxacin.
• B. Combining phenazopyridine with ciprofloxacin shortens the course of therapy.
• C. The use of phenazopyridine allows for a lower dosage of ciprofloxacin.
• D. Ciprofloxacin treats the infection, and phenazopyridine treats pain.

Correct answer: D

Rationale: Ciprofloxacin is an antibiotic that treats the infection, while phenazopyridine is a urinary analgesic that relieves pain. Choice A is incorrect because phenazopyridine does not decrease adverse effects of ciprofloxacin; it primarily addresses pain. Choice B is incorrect because combining phenazopyridine with ciprofloxacin does not shorten the course of therapy; they serve different purposes. Choice C is incorrect because the use of phenazopyridine does not allow for a lower dosage of ciprofloxacin; they have independent roles in UTI management.
