A nurse is preparing to administer acetaminophen 56 mg PO to a newborn.Available is acetaminophen oral solution 160 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1.8"]

Dose = Desired dose / Available dose x Volume Therefore;

Dose = (56 mg / 160 mg) x 5 mL Therefore;

Dose = 0.35 x 5 mL Dose = 1.75 mL

Round to the nearest tenth: Dose = 1.8 mL

The nurse should administer 1.8 mL

Correct Answer is ["188"]

Explanation

Infusion rate = Volume / Time Therefore;

Infusion rate= 1,500 mL / 8 hr

Infusion rate = 187.5 mL/hr

Rounded off to the nearest whole number; 188ml/hr

A. The nurse should ensure that the rate of the client's terbutaline infusion does not exceed 18 mg/hr. B. The nurse should weigh the client to determine the rate of the terbutaline infusion. C. The nurse should increase the drip rate of the infusion by 5 mL/hr when titrating the dosage. D. The nurse should initiate the infusion of terbutaline if the client has five or more contractions in 1 hr.

Correct Answer is D

Explanation

Choice A reason: Ensuring that the rate of the client's terbutaline infusion does not exceed 18 mg/hr is incorrect. The prescription specifies the maximum rate as 30 mcg/min, not 18 mg/hr. The units are different, and the prescribed rate is much lower than 18 mg/hr. Terbutaline is typically administered in micrograms per minute, and the nurse should follow the specific rate and titration instructions provided in the prescription.

Choice B reason: Weighing the client to determine the rate of the terbutaline infusion is not necessary according to the prescription. The dosage and titration instructions are based on the number of uterine contractions and not on the client's weight. While weight-based dosing is common for some medications, this prescription provides clear guidelines for adjusting the infusion rate based on the client's contraction pattern.

Choice C reason: Increasing the drip rate of the infusion by 5 mL/hr when titrating the dosage is incorrect. The prescription specifies increasing the infusion rate by 5 mcg/min every 10 minutes until contractions stop, not by 5 mL/hr. The nurse should follow the prescribed titration instructions, which are based on micrograms per minute, to ensure the correct dosage and avoid potential complications.

Choice D reason: This is the correct interpretation of the prescription. The nurse should initiate the infusion of terbutaline if the client has five or more contractions in 1 hour. The prescription indicates that the infusion should start at 2.5 mcg/min and be increased by 5 mcg/min every 10 minutes until the contractions stop, with a maximum rate of 30 mcg/min. This approach helps manage uterine contractions effectively and ensures the client receives the appropriate dosage based on their contraction pattern.
