Rn Hesi Med Surg Dosage Calculations ( 55 Questions)
A 4-year-old is admitted with croup and receives a prescription for a single dose of dexamethasone 0.6 mg/kg IM. The child weighs 35 pounds. How many mg should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
To answer this question, we need to convert the child's weight from pounds to kilograms, and then multiply by the prescribed dose per kg.
One pound is equal to 0.454 kg, so 35 pounds is equal to 0.454 x 35 = 15.89 kg. We can round this to 16 kg for simplicity.
The prescribed dose is 0.6 mg/kg IM, which means that for every kg of body weight, the child should receive 0.6 mg of dexamethasone by intramuscular injection.
To find out how many mg of dexamethasone are needed for a single dose, we can multiply the child's weight by the prescribed dose:
16 x 0.6 =9.6
Therefore, the nurse should administer about 10 mg of dexamethasone for a single dose.
