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.

Explanation
Calculating the Ferrous Fumarate Dose
Problem: Administer ferrous fumarate 3 mg/kg/day PO three times daily to an 88-pound child. The available concentration is 100 mg/5 mL.
Steps:
Convert pounds to kilograms:
88 pounds x (1 kg / 2.20462 pounds) ≈ 39.9 kg
Calculate the daily dose:
3 mg/kg/day x 39.9 kg = 119.7 mg/day
Calculate the dose per administration (TID):
119.7 mg/day / 3 doses = 39.9 mg/dose
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (39.9 mg) and the concentration of the medication (100 mg/5 mL).
Proportion:
x mL / 39.9 mg = 5 mL / 100 mg
Cross-multiply:
100x = 199.5
Solve for x:
x = 199.5 / 100
x ≈ 2
Answer: The child should receive approximately 2 mL of ferrous fumarate oral suspension for each dose.
Correct Answer is ["2.5"]
Explanation
To calculate the volume of furosemide to be administered, we can use the following formula:
Volume to administer = (Prescribed dose) / (Concentration)
Plugging in the given values:
Volume to administer = 25 mg / (40 mg/4 mL)
Volume to administer = 25 mg x (4 mL / 40 mg)
Volume to administer = 2.5 mL
Therefore, the nurse should administer 2.5 mL of furosemide (Lasix).
