A client's dose of benazapril is increased from 10 to 20 mg PO daily. The medication is available in 5 mg tablets. The nurse administered 10 mg one hour before the health-care provider revised the prescription. How many additional tablets should the nurse administer now? (Enter numeric value only.)
The Correct Answer is ["2"]
To calculate the number of additional tablets needed, we'll first determine the total number of tablets required for the new dose of 20 mg.
Step 1: Calculate the total number of tablets needed for the new dose:
Total Tablets = Desired Dose (mg) / Tablet Strength (mg)
Total Tablets = 20 mg / 5 mg/tablet
Total Tablets = 4 tablets
Step 2: Determine the number of tablets already administered:
The nurse administered 10 mg, which is equivalent to 2 tablets (since each tablet is 5 mg).
Step 3: Calculate the number of additional tablets needed:
Additional Tablets = Total Tablets - Tablets Already Administered
Additional Tablets = 4 tablets - 2 tablets
Additional Tablets = 2 tablets
Therefore, the nurse should administer 2 additional tablets of benazapril to reach the new prescribed dose of 20 mg.

Explanation
Calculating the Inamrinone Infusion Rate
Step 1: Convert weight to kilograms:
183 lbs x (1 kg / 2.20462 lbs) ≈ 83.0 kg
Step 2: Calculate the desired dose rate in mcg/minute:
8 mcg/kg/minute x 83.0 kg ≈ 664 mcg/minute
Step 3: Calculate the concentration of inamrinone in the IV solution:
0.1 grams/100 mL = 100 mg/100 mL = 1 mg/mL
Step 4: Calculate the infusion rate in mL/hour:
First, convert mcg to mg:
664 mcg x (1 mg / 1000 mcg) = 0.664 mg/minute
Then, set up a proportion:
x mL/hour / 0.664 mg/minute = 60 minutes/hour / 1 mg/mL
Cross-multiply and solve for x:
x mL/hour = 0.664 mg/minute x 60 minutes/hour / 1 mg/mL
x mL/hour ≈ 40 mL/hour
Therefore, the nurse should program the infusion pump to deliver approximately 40 mL/hour.

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.
