Answer :
To address this question, we'll break it down step-by-step:
a. Convert the child's weight from pounds to kilograms.
Weight in pounds (lb) = 94 lb.
To convert pounds to kilograms, use the conversion factor:
[tex]\text{Weight in kg} = \frac{\text{Weight in lb}}{2.20462}[/tex]
[tex]\text{Weight in kg} = \frac{94}{2.20462} \approx 42.64 \text{ kg}[/tex]
So, the child's weight is approximately 42.64 kg.
b. Calculate the safe dosage range for this child.
The recommended oral dosage is 0.5 to 2 mg/kg/24 h divided twice a day.
- Minimum daily dosage:
[tex]0.5 \text{ mg/kg} \times 42.64 \text{ kg} = 21.32 \text{ mg/24 h}[/tex]
- Maximum daily dosage:
[tex]2 \text{ mg/kg} \times 42.64 \text{ kg} = 85.28 \text{ mg/24 h}[/tex]
However, the maximum dosage is not to exceed 80 mg/24 h. So, the range is:
21.32 mg/24 h to 80 mg/24 h
c. Determine if the order is safe.
The physician's order is 45 mg twice a day, which totals:
[tex]45 \text{ mg} \times 2 = 90 \text{ mg/24 h}[/tex]
Since 90 mg/24 h exceeds the maximum safe dosage of 80 mg/24 h, the order is not safe.
d. Would you administer this medication as dosed? If not, why not?
No, I would not administer this medication as dosed because the total prescribed daily dosage of 90 mg exceeds the recommended maximum of 80 mg/24 h. Administering a dosage higher than the safe range could increase the risk of adverse effects. I would recommend discussing this with the prescribing physician to adjust the dosage appropriately.
