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.)
Answer and Explanation

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.

Correct Answer is ["499"]

Explanation

Calculating the Lactated Ringer's Infusion Rate

Step 1: Convert pounds to kilograms:

110 pounds x (1 kg / 2.20462 pounds) ≈ 49.9 kg

Step 2: Calculate the total fluid requirement for 24 hours using the Parkland formula:

Total Fluid (mL) = 4 mL/kg/%TBSA x Body Weight (kg) x %TBSA

Total Fluid = 4 mL/kg/%TBSA x 49.9 kg x 40%

Total Fluid = 7984 mL

Step 3: Calculate the fluid volume for the first 8 hours:

First 8 Hours Fluid = Total Fluid / 2

First 8 Hours Fluid = 7984 mL / 2

First 8 Hours Fluid = 3992 mL

Step 4: Calculate the infusion rate for the first 8 hours:

Infusion Rate (mL/hour) = First 8 Hours Fluid / 8 hours

Infusion Rate = 3992 mL / 8 hours

Infusion Rate ≈ 499 mL/hour

Therefore, the nurse should set the infusion pump to deliver approximately 499 mL/hour during the first 8 hours.

Correct Answer is ["36"]

Explanation

Calculating the Dobutamine Infusion Rate

Step 1: Convert grams to milligrams:

0.5 grams = 500 mg

Step 2: Calculate the concentration of dobutamine in the IV solution:

500 mg / 250 mL = 2 mg/mL

Step 3: Convert micro-grams to milligrams:

1200 mcg x (1 mg / 1000 mcg) = 1.2 mg

Step 4: Set up a proportion:

We want to find the infusion rate in mL/minute.

We know the desired dose rate (1.2 mg/minute) and the concentration of the medication (2 mg/mL).

Proportion:

x mL/minute / 1.2 mg/minute = 1 mL / 2 mg

Step 5: Cross-multiply and solve for x:

2x = 1.2

x = 0.6 mL/minute

Step 6: Convert mL/minute to mL/hour:

0.6 mL/minute x 60 minutes/hour = 36 mL/hour

Therefore, the nurse should program the infusion pump to deliver 36 mL/hour.
