A child weighs 52 lb. The child has a fever and the doctor orders acetaminophen. The safe dose range of this medication is 10-15 mg/kg every 6 hours. What is the maximum safe daily dose of the medication the client can receive? Round to the nearest whole number. Record numerical answers only.
The Correct Answer is ["1418"]
Convert the child's weight from pounds (lb) to kilograms (kg).
Weight in kg = 52 lb / 2.2 lb/kg
= 23.636 kg.
Maximum safe dose per kilogram per administration = 15 mg/kg.
Calculate the maximum single dose in milligrams (mg).
Maximum single dose (mg) = Maximum dose per administration (mg/kg) × Weight (kg)
= 15 mg/kg × 23.636 kg
= 354.54 mg.
Determine the number of times the medication can be administered per day.
Given every 6 hours, Number of doses per day = 24 hours / 6 hours/dose
= 4 doses/day.
Calculate the maximum safe daily dose of the medication.
Maximum safe daily dose (mg) = Maximum single dose (mg) × Number of doses per day
= 354.54 mg × 4 doses
= 1418.16 mg.
Round the answer to the nearest whole number.
= 1418 mg.

Correct Answer is ["4.1"]
Explanation
Convert the client's weight from pounds (lb) to kilograms (kg).
Weight in kg = 48.6 lb / 2.2 lb/kg
= 22.09 kg.
Calculate the total daily desired dose in milligrams (mg).
Total daily desired dose (mg) = Desired dose (mg/kg/day) × Weight (kg)
= 30 mg/kg/day × 22.09 kg
= 662.7 mg/day.
Determine the number of doses per day.
Doses are administered every six hours, so Number of doses per day = 24 hours / 6 hours/dose
= 4 doses/day.
Calculate the dose per administration in milligrams (mg).
Dose per administration (mg) = Total daily desired dose (mg) / Number of doses per day
= 662.7 mg / 4 doses
= 165.675 mg.
Convert the available concentration from grams (g) to milligrams (mg).
Available concentration = 0.2 g/5 mL
1 g = 1000 mg
Available concentration in mg/mL = (0.2 g × 1000 mg/g) / 5 mL
= 200 mg / 5 mL
= 40 mg/mL.
Calculate the volume in milliliters (mL) to administer per dose.
Volume (mL) = Desired dose per administration (mg) / Available concentration (mg/mL)
= 165.675 mg / 40 mg/mL
= 4.141875 mL.
Round the answer to the nearest tenths place.
= 4.1mL
Correct Answer is C
Explanation
A. Place on the back immediately after feeding: The infant should always be placed on their back to sleep, but placing the infant on the back immediately after feeding may worsen gastroesophageal reflux (GER). The infant should be kept upright for at least 30 minutes after feeding to help reduce reflux.
B. Administer prescribed medications before each feeding: While medications may be prescribed for gastroesophageal reflux, they should be administered according to the healthcare provider's specific instructions, which may vary.
C. Feed with formula thickened with rice cereal: Thickening the formula with rice cereal is a common intervention to help reduce the symptoms of gastroesophageal reflux. The thicker consistency can reduce the likelihood of reflux by decreasing the flow of milk back into the esophagus.
D. Hold in a horizontal position while feeding: Holding an infant in a horizontal position during feeding can worsen GER symptoms. The infant should be held in a more upright position while feeding to reduce reflux.
