An 88 pound child with iron deficiency anemia has been prescribed ferrous fumarate 3 mg/kg/day PO three times daily. The medication is available in oral suspension of 100 mg/5 ml. The nurse is instructing the mother in measuring the correct dose. How many ml should the child receive for each dose?

Answer and Explanation

The Correct Answer is ["2"]

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.

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 ["2"]

Explanation

To determine the number of tablets needed, we can set up a proportion:

x tablets / 0.6 mg = 1 tablet / 0.4 mg

Cross-multiplying:

0.4x = 0.6

Solving for x:

x = 0.6 / 0.4

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 nitroglycerin 0.4 mg sublingually if the client experiences chest pain
