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?

A.

390 mg

B.

27 mg

C.

1560 mg

D.

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 C

Explanation

The gt/min is 25.

This answer is correct because it is based on a simple formula and calculation. The nurse should use the following formula to calculate the gt/min:

gt/min = (Volume in mL x Drop factor in gt/mL) / Time in min

Plugging in the given values, the nurse should get:

gt/min = (100 mL x 15 gt/mL) / 60 min

gt/min = 25

Therefore, the gt/min is 25.

Correct Answer is C

Explanation

The instruction that should be given to this client for the effective management of hypertension is to take

**five tablets** of bisoprolol per day, each containing 100 mg.

This is because the new order of 500 mg of bisoprolol per day is twice as much as the current dose of 250 mg of bisoprolol per day (two and a half tablets of 100 mg each). Therefore, the client needs to double the number of tablets they take per day from two and a half to five.
