Docusate sodium (Colace) 0.3 grams is prescribed for a client who has frequent constipation. Each capsule contains 100 mg. How many capsules should the nurse administer?
Answer and Explanation

The Correct Answer is ["3"]

First, let's convert grams to milligrams:

0.3 grams x 1000 mg/gram = 300 mg

Then, set up a proportion:

x capsules / 300 mg = 1 capsule / 100 mg

Cross-multiply:

100x = 300

Solve for x:

x = 300 / 100

x = 3

Therefore, the nurse should administer 3 capsules of docusate sodium (Colace).

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.

Correct Answer is ["0.8"]

Explanation

First, calculate the loading dose:

Loading dose = 60 units/kg x 90 kg = 5400 units

Since the maximum loading dose is 4,000 units, the nurse should administer 4,000 units.

Next, calculate the volume to administer:

Volume = Desired Dose (units) / Concentration (units/mL)

Volume = 4,000 units / 5,000 units/mL

Volume = 0.8 mL

Therefore, the nurse should administer 0.8 mL of heparin.
