A nurse is caring for a school-age child who has attention deficit disorder and a new prescription for methylphenidate 10 mg PO at 0800 and 1200 and 5 mg at 1600. What is the total daily dose in mg prescribed for this client? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Correct Answers:

25

Rationale :

📏 Calculation:

0800 dose: 10 mg

1200 dose: 10 mg

1600 dose: 5 mg

Total daily dose = 10 + 10 + 5 = 25 mg

Answer 2

Correct Answers:

1

Rationale :

Total daily dose = 450 mg

Doses per day (every 8 hours) = 24 ÷ 8 = 3 doses/day

Amount per dose = 450 ÷ 3 = 150 mg/dose

Tablet strength available = 150 mg/tablet

🔢 Tablets per dose = 150 mg ÷ 150 mg = 1 tablet

✅ Answer: 1 tablet

Answer 4

Correct Answers:

Sertraline 125 mg daily

Rationale :

✴️ Sertraline (Zoloft) is typically started at 25–50 mg/day for depression or anxiety and titrated up in increments of 25–50 mg at weekly intervals.

✴️ The maximum recommended daily dose is 200 mg, but there is no available tablet strength of 125 mg, making this prescription unclear and needing clarification.

✴️ Proper administration would usually involve available tablet strengths (25 mg, 50 mg, 100 mg), and combination dosing (e.g., 100 mg + 25 mg).

✴️ All other prescriptions listed (propranolol ER, clonidine patch, pantoprazole BID) are clear, appropriate, and follow standard dosing guidelines.

Answer 5

Correct Answers:

Divalproex 1.5 g PO twice daily

Rationale :

💊 Divalproex is effective for treating acute mania, but the standard initial dose usually starts at 750 mg/day and is then titrated up.

💊 A prescription for 1.5 g twice daily (total 3,000 mg/day) is excessive and places the client at risk for toxicity, especially if not based on body weight or serum levels.

💊 The maximum recommended daily dose generally should not exceed 60 mg/kg/day unless under close monitoring.

💊 The nurse must clarify this high dose with the provider before administration to prevent serious adverse effects such as hepatic toxicity or CNS depression.
