Question 1 of 5
A nurse is caring for a child who has ADHD and a prescription for methylphenidate oral solution 40 mg per day, divided into two doses. Available is methylphenidate oral solution 10 mg/5 mL. How many mL of methylphenidate should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 10
Rationale:
Correct
Answer: 10 mL
Rationale:
1. The child needs 40 mg/day, divided into two doses.
2. Each dose should be 20 mg (40 mg ÷ 2 doses).
3. The available concentration is 10 mg/5 mL.
4.
To administer 20 mg, the nurse should give 10 mL (20 mg ÷ 10 mg/5 mL = 4 mL; 4 mL x 2 = 8 mL).
5. Rounding up to the nearest whole number, the nurse should administer 10 mL per dose.
Summary:
A, B, C, D, E, F, G:
- Incorrect because they do not follow the correct calculation steps to determine the amount of methylphenidate needed per dose.
- Only choice 10 aligns with the proper dosage calculation for the child with ADHD.
