A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three divided doses to a client who weighs 85 kg. The amount available is Tobramycin 40 mg/mL. How many mL should the nurse administer per dose?
(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 ["2.1"]

To calculate the amount of tobramycin that the nurse should administer per dose, we can use the following steps:

Calculate the total daily dosage required based on the client's weight and the prescribed dosage.

Determine the dosage per each of the three divided doses.

Calculate the volume of the drug needed for each dose using the concentration of the available tobramycin solution.

Given:

Client's weight = 85 kg

Prescribed dosage = 3 mg/kg/day

Available concentration of tobramycin = 40 mg/mL

Let's calculate step by step:

Calculate the total daily dosage required:

Total daily dosage = 3 mg/kg/day × 85 kg = 255 mg/day

Determine the dosage per each of the three divided doses:

Dosage per dose = Total daily dosage / 3 = 255 mg / 3 = 85 mg

Calculate the volume of the drug needed for each dose using the concentration of the available tobramycin solution:

Volume of drug per dose = Dosage per dose / Concentration of tobramycin

Volume of drug per dose = 85 mg / 40 mg/mL ≈ 2.1 mL

Rounding to the nearest tenth, the nurse should administer 2.1 mL of the tobramycin per dose.

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. 1 C. No answer is too low D. No answer is too high E. No answer is too high

Correct Answer is B

Explanation

This choice is correct because it is the result of dividing the ordered dose (0.25 mg) by the strength of the tablet (250 mcg or 0.25 mg). The formula for calculating the number of tablets to be given is:

Tablets = Dose/ Strength

Therefore, the number of tablets to be given is:

Tablets = 0.25 mg/250 mcg = 0.25 mg/0.25 mg = 1
