A nurse is preparing to administer insulin glargine to a child who has type 1 diabetes mellitus. The client is to receive 10 units subcutaneous once daily at bedtime. Reading the label on the unopened vial, the nurse should determine that the vial contains how many doses of this medication? (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 ["100"]
The label on the vial indicates that the insulin glargine has a concentration of 100 units per milliliter (U-100) and the total volume of the vial is 10 mL.
To calculate the total number of units in the vial, you multiply the volume by the concentration:
Total units = Volume × Concentration = 10 mL×100 units/mL = 1000 units
Then, to find out how many doses of 10 units each are in the vial,
you divide the total number of units by the number of units per dose:
Number of doses = Total units/ Units per dose
= 1000 units /10 units per dose
= 100 doses
So, the vial contains 100 doses of this medication when administered at 10 units per dose

Correct Answer is ["2"]
Explanation
Here's the breakdown:
Desired dose: 0.5 g (grams)
Conversion:
1 gram (g) is equal to 1000 milligrams (mg).
Therefore, we need to convert the desired dose from grams to milligrams:
Desired dose (mg) = 0.5 g x 1000 mg/g = 500 mg
Available dosage:
Each capsule contains 250 mg of cefaclor.
Calculation of capsules needed:
To find the number of capsules needed, we can divide the desired dose (in milligrams) by the amount of medication in each capsule (rounding to the nearest whole number):
Number of capsules (rounded) = Desired dose (mg) / Medication per capsule
= 500 mg / 250 mg/capsule
= 2 capsules (rounded to nearest whole number)
Correct Answer is ["1.8"]
Explanation
Here's the breakdown:
Convert client weight to kilograms (kg):
Client weight (kg) = Client weight (lb) / 2.2 lb/kg
Client weight (kg) = 154 lb / 2.2 lb/kg
Client weight (kg) ≈ 70 kg (rounded to nearest whole number)
Calculate desired gentamicin dose in milligrams (mg):
Desired dose (mg) = Client weight (kg) x Dose per kg
Desired dose (mg) = 70 kg x 1 mg/kg
Desired dose (mg) = 70 mg
Determine the volume of gentamicin solution to administer:
Concentration of available solution: 40 mg/mL
Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume to administer (mL) = 70 mg / (40 mg/mL)
Volume to administer (mL) = 1.75 mL (round to nearest tenth)
Therefore, the nurse should administer 1.8 mL of the gentamicin solution.
