A nurse is preparing to administer pentamidine 4 mg/kg IM to a client who weighs 154 lb. Available is pentamidine 100 mg/mL for injection. 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 ["2.8"]

Convert the patient's weight from pounds to kilograms:

154 lb ÷ 2.2 = 70 kg

Calculate the dose of pentamidine:

4 mg/kg × 70 kg = 280 mg

Determine the volume to be administered:

We have 100 mg/mL concentration of pentamidine.

280 mg ÷ 100 mg/mL = 2.8 mL

Therefore, the nurse should administer 2.8 mL of pentamidine to the client.

Correct Answer is ["10"]

Explanation

The nurse needs to administer 775 mg of amoxicillin. The available amoxicillin oral suspension is 400 mg/5 mL, which means there are 400 mg of amoxicillin in every 5 mL of the suspension.

Therefore, for a 775 mg dose, the nurse should administer:

775 mg/(400 mg/5mL) = 9.6875 mL of the suspension

So, the nurse should administer approximately 10 mL (rounded to the nearest whole number).

A. No answer is provided B. No answer is too low C. No answer is too high D. 3.5

Correct Answer is D

Explanation

Choice A reason: This choice is incorrect because it does not provide a numerical answer to the question.

Choice B reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is lower than the correct one, which is not true.

Choice C reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is higher than the correct one, which is not true.

Choice D reason: This choice is correct because it is the result of dividing the ordered dose (3.5 mg) by the concentration of the vial (1 mg/mL). The formula for calculating the volume to be drawn up is:

Volume = Dose/Concentration

Therefore, the volume to be drawn up is:

Volume = 3.5 mg/(1 mg/mL) = 3.5 mL
