What is the total hydromorphone delivered in 24 hours when including both basal and on-demand boluses?

• A. 5.3 mg
• B. 10.6 mg
• C. 2.65 mg
• D. 0 mg

Answer: (A)

The total hydromorphone delivered in 24 hours is the sum of what is given as a basal infusion over the day plus all on‑demand boluses taken during that same 24‑hour period. So you calculate it as: basal rate (mg/hour) × 24 hours + total bolus doses (the sum of every bolus given in that day).

For example, if the basal rate is 0.2 mg/hour, the basal portion is 0.2 × 24 = 4.8 mg. If on‑demand boluses add up to 0.5 mg in that day, the total delivered is 4.8 + 0.5 = 5.3 mg, which matches the given answer.

Why the other numbers don’t fit: 10.6 mg would require a larger combination of basal and boluses than in this scenario, 2.65 mg is roughly half of 5.3 mg and wouldn't account for both basal and bolus contributions, and 0 mg would mean no drug was delivered at all. The key idea is adding both components to get the daily total.
