A client with hypertension receives a prescription for lisinopril 60 mg PO every day. The drug is available in 40 mg tablets. How many tablets should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2"]
To determine the number of tablets needed, we can set up a proportion:
x tablets / 60 mg = 1 tablet / 40 mg
Cross-multiplying:
40x = 60
Solving for x:
x = 60 / 40
x = 1.5
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets of lisinopril.

x = 7.5 / 5
x = 1.5

Calculation for 3/4 Strength Ensure Feeding
Prompt: To determine how many milliliters of full-strength Ensure to use to prepare a 3/4 strength feeding.
Given:
Desired volume of 3/4 strength Ensure: 275 mL
Strength required: 3/4
Formula:
Amount of full-strength Ensure = Total volume x Strength required
Calculation:
Amount of full-strength Ensure = 275 mL x (3/4)
Amount of full-strength Ensure = (275 x 3) / 4
Amount of full-strength Ensure = 825 / 4
Amount of full-strength Ensure = 206.25 mL
Rounding to the nearest whole number:
Amount of full-strength Ensure = 206 mL
Therefore, the nurse should use 206 mL of full-strength Ensure to prepare the feeding.
