A nurse is preparing to administer ondansetron 4 mg IM to a client who reports nausea following a cesarean birth. Available is ondansetron injection 2 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
To administer the correct dose of ondansetron, which is 4 mg intramuscularly, the nurse needs to calculate the volume of ondansetron injection required based on the concentration provided. The available ondansetron injection has a concentration of 2 mg/mL. To find the volume needed to deliver 4 mg, the nurse should divide the ordered dose by the concentration of the drug: 4 mg divided by 2 mg/mL equals 2 mL.

Correct Answer is ["0.75"]
Explanation
To administer the correct dose of enoxaparin, which is 75 mg, when the available injection concentration is 100 mg/mL, the nurse needs to calculate the volume of enoxaparin to be administered. The calculation is based on the formula: Volume = Dose / Concentration. So, for a dose of 75 mg and a concentration of 100 mg/mL, the calculation would be 75 mg / 100 mg/mL = 0.75 mL.
Correct Answer is ["2"]
Explanation
To administer the correct dose of ciprofloxacin, which is 0.5 grams (g), the nurse needs to convert this amount into milligrams (mg) because the available tablets are measured in mg. There are 1000 mg in 1 g, so 0.5 g is equal to 500 mg. Since each tablet contains 250 mg, the nurse would need to administer two tablets to reach the prescribed dose of 500 mg.
