Correct Answer is ["1"]
Explanation
Client's weight: 220 lb
Desired dose of enoxaparin: 1 mg/kg
Available strength of enoxaparin: 30 mg/0.3 mL
First, convert the client's weight from pounds to kilograms:
220 lb ÷ 2.20462 ≈ 99.79 kg
Now, calculate the desired dose of enoxaparin:
Desired dose = Dosage per kg × Weight Desired dose = 1 mg/kg × 99.79 kg ≈ 99.79 mg 30mg = 0.3ml
Therefore, 99.79mg = 99.79 * 0.3/30
=0.9979
Rounded off to the nearest whole number= 1ml
Correct Answer is ["1.8 "]
Explanation
Given:
- Desired dose of ceftriaxone: 75 mg/kg/day
- Child's weight: 37 lb
- Available strength of ceftriaxone after reconstitution: 350 mg/mL
First, convert the child's weight from pounds to kilograms: 37 lb ÷ 2.20462 = 16.78 kg (rounded to the nearest hundredth)
The total daily dose of ceftriaxone:
Total daily dose = Desired dose × Child's weight
Total daily dose = 75 mg/kg/day × 16.78 kg Total daily dose ≈ 1258.5 mg
Since the total daily dose is to be divided into two equal doses, each dose would be:
Each dose = Total daily dose / Number of doses per day Each dose = 1258.5 mg / 2
Each dose = 629.25 mg
The milliliters of ceftriaxone correspond to each dose:
Volume (mL) = Dose / Concentration
Volume (mL) = 629.25 mg / 350 mg/mL Volume (mL) ≈ 1.8 mL
So, the nurse should administer approximately 1.8 mL of ceftriaxone per dose.
