A nurse has to administer IV ampicillin every 6 hours to a child who weighs 10.4 kg. The prescribed dose is 150 mg/kg/day.
What is the amount of ampicillin in one dose?

390 mg

27 mg

1560 mg

260 mg

Answer and Explanation

The Correct Answer is A

The amount of ampicillin in one dose is 390 mg.

This answer is correct because it is based on a series of multiplication and division calculations. The nurse should follow these steps to determine the amount of ampicillin in one dose:

1) Multiply the prescribed dose per kilogram per day by the child's weight in kilograms to get the total dose per day in milligrams, as follows:

150 mg/kg/day x 10.4 kg = 1560 mg/day

Therefore, the child needs 1560 mg of ampicillin per day.

2) Divide the total dose per day by the number of doses per day to get the amount of each dose in milligrams, as follows:

1560 mg/day / 4 doses/day = 390 mg/dose

Therefore, the amount of ampicillin in one dose is 390 mg.

Correct Answer is B

Explanation

One inch is equal to **2.54 centimeters**²³⁴. To convert inches to centimeters, you can multiply the value in inches by 2.54. For example, 2.54 centimeters x 1 inch = 2.54 centimeters.

Therefore, to convert 2.54 centimeters to inches, you can divide the value in centimeters by 2.54. For example, 2.54 centimeters / 2.54 = 1 inch.

The answer is **1 inch**.

A. 41.7 mL/hr B. 83.3 mL/hr C. 20.8 mL/hr D. 62.5 mL/hr

Correct Answer is D

Explanation

To calculate the rate of infusion, we need to divide the total volume to be infused (1.5 L) by the total time of infusion (24 hours)

1.5 L = 1500 mL (since 1 L = 1000 mL)

Dividing 1500 mL by 24 hours gives us the rate of 62.5 mL/hr.
