An order is written for oxazepam for a 6-year-old child. The nurse notices that there is no established dosage for children 6 to 12 years of age. Knowing that the usual adult dose is 10 mg t.i.d., what would the nurse calculate the appropriate dose to be?
- A. 0.03 mg t.i.d.
- B. 0.3 mg t.i.d.
- C. 1.8 mg t.i.d.
- D. 3.3 mg t.i.d.
Correct Answer: D
Rationale: Because the nurse only knows the child's age, the nurse would need to use Young's Rule to determine the appropriate dosage. Use the formula, child's dose equals the age of the child in years divided by the child's age plus 12 times the average adult dose to calculate the answer. Dose = (6/[6+12]) 10 mg (6/18 = 0.33 10 = 3.3).
