Answer Choices:

A. 0.5 ✓ Correct Answer

Correct Answer:

0.5

Rationale:

Step-by-step calculation:

Formula:

Tablet dose = Dose ordered (mg) ÷ Dose available (mg per tablet)

Step 1: Identify known values

Dose ordered = 2.5 mg

Available = 5 mg per tablet

Step 2: Plug values into the formula

2.5 mg ÷ 5 mg = 0.5 tablet

Step 3: Round to the nearest tenth

0.5 is already to the nearest tenth

✅ Final Answer: 0.5 tablet

Educational Insight:

Lisinopril is an ACE inhibitor used to treat hypertension and heart failure, particularly in older adults. It is crucial to start with lower doses in this population due to age-related renal function decline and increased sensitivity to blood pressure changes. Administering half-tablet doses requires care; tablets must be scored for safe and accurate splitting.
