A client diagnosed with tuberculosis is prescribed rifampin, 4 mg/kg. 8 hourly for 6 days. The client weighs 43 kg. How many 100 mg bottles of rifampin will be required for this client?

Round your answer to the nearest whole number.

Answer and Explanation

The Correct Answer is B

The correct answer is choice B. 31. To find the number of bottles required, use the formula: (dose x frequency x duration) / (bottle size x bottle concentration). In this case, (4 mg/kg x 43 kg x 3 times/day x 6 days) / (100 mg/bottle) = 30.96 bottles. Round up to the nearest whole number to get 31 bottles.

Correct Answer is A

Explanation

To administer 1 mg of Stadol, we need 1/2 mL of 2 mg/mL injectable solution. .

So, to administer 1 mg of Stadol, the nurse should administer 0.5 mL of the injectable solution.

A. 0.04 mg B. 0.25 mg C. 3.75 mg D. 2.5 mg

Correct Answer is D

Explanation

A. 0.04 mg

This is far too small.
It might come from a miscalculation involving the concentration (1 mg/mL) and volume (5 mL), but incorrectly dividing again by 100.
Not clinically reasonable because the patient would barely receive any drug.

B. 0.25 mg

This is also incorrect.
It could result from mistakenly dividing 5 mg by 20 minutes instead of 2 minutes.
Again, far below the actual ordered rate.

C. 3.75 mg

This is incorrect but closer.
It might come from a misstep like subtracting 1.25 mg from the correct answer (2.5 mg) or misusing the concentration.
Still not the right calculation.

D. 2.5 mg

Correct answer.
Direct calculation: 5 mg ÷ 2 minutes = 2.5 mg/min.
Matches the ordered dose and administration time.
