Penicillin G procaine 240,000 units intramuscularly is prescribed for a 4-year-old childwho has a streptococcal respiratory infection. The medication vial is labeled 1,200,000
units/2 mL. How many mL should the nurse administer? (Enter numeric value only. If
rounding is required, round to the nearest tenth.)
Answer and Explanation
Correct Answer: 0.4 mL mL
Explanation
To find the answer, we can use the following formula:
(mL to be administered) = (units prescribed) / (units per mL)
Substituting the given values, we get:
(mL to be administered) = (240,000) / (1,200,)
Simplifying, we get:
(mL to be administered) = (240,000 x 2) / (1,200,000)
(mL to be administered) = 480,,200,000
(mL to be administered) = 0.4
Therefore, the nurse should administer 0.4 mL of penicillin G procaine to the child.
WGU Hesi Med Surg A 4-year-old is admitted with croup and receives a prescription for a single dose of
dexamethasone 0.6 mg/kg IM. The child weighs 35 pounds. How many mg should the
nurse administer? (Enter numerical value only. If rounding is required, round to the
nearest whole number.)
Answer and Explanation
Correct Answer: 10 mg
Explanation
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Multiply the weight in kilograms by the dosage in mg/kg
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (35) / (2.2) = 15.909
- (dose in mg) = (0.6) x (15.909) = 9.545
- (rounded dose in mg) = 10
Therefore, the nurse should administer 10 mg of dexamethasone to the child. A patient is receiving a secondary infusion of vancomycin 1,500 mg in 250 mL to be

required, round to the nearest whole number.)
Answer and Explanation
Correct Answer: 21 gtt\/min
Explanation
To find the answer, we can use the following formula:
