2. Describe the process used to convert the client's weight from pounds to
kilograms.
To convert pounds to kilograms, add 2.2 to the weight in pounds.
To convert pounds to kilograms, subtract 2.2 from the weight in
pounds.
To convert pounds to kilograms, divide the weight in pounds by
2.2.

3. Describe the process used to calculate the infusion rate for the IV
medication in this scenario.
The infusion rate is based solely on the medication dosage
without considering the volume.
The infusion rate is calculated by setting up a proportion based
on the volume and time, then solving for the unknown volume
for 60 minutes.
, The infusion rate is calculated by multiplying the volume by the
time in minutes.
The infusion rate is determined by dividing the total volume by the
total time in hours.

pump. At what rate will the nurse set the IV pump? Round to the nearest
whole number
150 mL/hr
133 mL/hr
125 mL/hr

9. Describe the method used to calculate the number of azithromycin
tablets needed per dose.
The calculation is based on the patient's weight and age.
The calculation uses the formula D/H, where D is the prescribed
dose and H is the available dose.
The calculation requires converting the tablets into liquid form.
The calculation involves multiplying the prescribed dose by the
number of days.

many tablets should the nurse administer?
3
2
1
4
12. If the nurse had to adjust the tube feeding rate to 100 ml/hour for the
same duration, what would the new total fluid intake be before
considering the residual?
825
945
695
1100
13. The order for a child reads: "Give cefoxitin (Mefoxin) 160 mg/kg/day,
