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

This number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters, because one inch is equal to 2.54 centimeters. To convert inches to centimeters, the formula is:

centimeters = inches × 2.54

For example, if a patient's height is 60 inches, then the height in centimeters is:

centimeters = 60 × 2.54
centimeters = 152.4

Therefore, the patient's height is 152.4 centimeters.

A. 1.15 in. B. 1 in. C. 0.06 in. D. 6.45 in.

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**.
