The healthcare provider prescribes ceftazidime 30 mg/kg/day for an infant weighing 3,500 grams. What dose should the nurse administer daily to this infant? (Enter numeric value only.)
The Correct Answer is ["105"]
To find the answer, we can use the following steps:
- Convert the infant's weight from grams to kilograms by dividing by 1000
- Multiply the weight in kilograms by the dosage in mg/kg/day
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (3,500) / (1000) = 3.5 kg
- (dose in mg/day) = (30) x (3.5) = 105 mg/day
- (rounded dose in mg/day) = 105 mg
Therefore, the nurse should administer 105 mg of ceftazidime daily to this infant.

Explanation
To determine the infusion rate in mL/hour for the dopamine solution:
-
Calculate the total dose per minute:
3 mcg/kg/min×91 kg=273 mcg/min3mcg/kg/min×91kg=273mcg/min. -
Convert mcg/min to mcg/hour:
273 mcg/min×60 min/hour=16,380 mcg/hour273mcg/min×60min/hour=16,380mcg/hour. -
Convert mcg to mg:
16,380 mcg÷1,000=16.38 mg/hour16,380mcg÷1,000=16.38mg/hour. -
Determine the concentration of the solution:
400 mg÷250 mL=1.6 mg/mL400mg÷250mL=1.6mg/mL. -
Calculate the mL/hour required:
16.38 mg/hour÷1.6 mg/mL=10.2375 mL/hour16.38mg/hour÷1.6mg/mL=10.2375mL/hour.
Rounded to the nearest tenth:
10.2 mL/hour.
Correct Answer is ["8"]
Explanation
The correct answer is 8 tablets. To find the answer, we can use the following steps:
- Convert the daily maximum dosage from grams to milligrams by multiplying by 1000
- Divide the daily maximum dosage in milligrams by the amount of calcium polycarbophil in one tablet
- Round the result to the nearest whole number
Using these steps, we get:
- (daily maximum dosage in mg) = (5) x (1000) = 5000 mg
- (number of tablets) = (5000) / (625) = 8 tablets
- (rounded number of tablets) = 8
Therefore, the client could safely take up to 8 tablets of calcium polycarbophil in one day.
