A child with growth failure is receiving somatropin (rDNA origin) 1.25 mg subcutaneously (subQ) daily. The nurse reconstitutes the vial with 5 mL of bacteriostatic water for injection to yield a solution concentration of 5 mg/mL. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest hundredth.)
The Correct Answer is ["0.25"]
Here's how to calculate the volume (mL) the nurse should administer for somatropin:
1. We know the following:
Prescribed dose: 1.25 mg somatropin (given)
Concentration after reconstitution: 5 mg/mL (given)
2. We need to find the volume (mL) to administer for the prescribed dose (1.25 mg) considering the concentration (5 mg/mL) of the reconstituted solution.
Volume to administer (mL): Dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 1.25 mg / 5 mg/mL
Volume to administer (mL) = 0.25 mL (round to nearest hundredth)
Therefore, the nurse should administer 0.25 mL of the reconstituted somatropin solution subcutaneously.

Correct Answer is ["168"]
Explanation
Here's how to calculate the total zidovudine dosage (mg) the nurse should prepare to administer:
1. Convert client weight from pounds to kilograms:
Client weight (kg) = Client weight (lb) / 2.2
Client weight (kg) = 185 lb / 2.2
Client weight (kg) = 84.1 kg (approximately)
2. Calculate the total zidovudine dose based on weight and prescribed dosage:
Dose (mg) = Dose (mg/kg) x Client weight (kg)
Dose (mg) = 2 mg/kg x 84.1 kg
Dose (mg) = 168.2 mg (round to nearest whole number as requested)
Therefore, the nurse should prepare to administer 168 mg of zidovudine.
Correct Answer is ["0.5"]
Explanation
here's how to calculate the volume (mL) of epinephrine the nurse should administer:
1. Client weight conversion:
Client weight: 110 pounds
Since medication dosage is based on weight per kilogram (kg), we need to convert the weight to kg for accurate calculation.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 110 pounds / 2.205 lbs/kg
Client weight (kg) = 50 kg (round to nearest whole number)
2. Epinephrine dosage:
Prescribed dose: 0.01 mg/kg (given)
3. Epinephrine concentration:
The medication is labeled 1 mg/mL. This indicates there are 1 mg of epinephrine per 1 mL of solution.
4. We need to find the volume (mL) containing the prescribed dose (based on weight) of epinephrine (0.01 mg/kg) considering the concentration (1 mg/mL) in the vial.
Total epinephrine dose (mg): Dose (mg/kg) x Client weight (kg)
Total epinephrine dose (mg): 0.01 mg/kg * 50 kg
Total epinephrine dose (mg): 0.5 mg (round to nearest tenth)
Volume to administer (mL): Total dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 0.5 mg / 1 mg/mL
Volume to administer (mL): 0.5 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 0.5 mL of epinephrine intramuscularly.
