A client with acute decompensated heart failure (HF) is to receive an IV infusion of inamrinone (Inocor) 8 mcg/kg/minute. The available vial of inamrinone is 0.1 grams/100 to be infused in 250ml bag of 0.9% normal saline (NS). The client's current weight is 183 lbs. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["40"]

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.

Correct Answer is ["1"]

Explanation

To calculate the number of capsules needed, we'll first convert grams to milligrams:

0.1 grams x 1000 mg/gram = 100 mg

Then, we can set up a proportion:

x capsules / 100 mg = 1 capsule / 100 mg

Cross-multiplying:

100x = 100

Solving for x:

x = 100 / 100

x = 1

Therefore, the nurse should administer 1 capsule of Dantrolene.

Correct Answer is ["2"]

Explanation

Understanding the Problem:

We need to administer 500 mg of amoxicillin/clavulanate potassium.

The available tablets contain 250 mg amoxicillin and 125 mg clavulanate potassium.

Solution:

Determine the total amount of active ingredients in the available tablets:

250 mg (amoxicillin) + 125 mg (clavulanate potassium) = 375 mg/tablet

Calculate the number of tablets needed:

500 mg (desired dose) / 375 mg/tablet = 1.33 tablets

Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.

Therefore, the nurse should administer 2 tablets for each dose.
