Question

What is the daily fluid requirement for a patient with a weight of 64 pounds (29.1 kg) using the maintenance fluid formula?

A) 1450 mL
B) 1500 mL
C) 1600 mL
D) 1650 mL

Answer 1

Using the maintenance fluid formula for a patient weighing 64 pounds (29.1 kg), the daily fluid requirement is closest to 1650 mL, so the answer is D) 1650 mL.

Step-by-step explanation:

To calculate the daily fluid requirement for a patient using the maintenance fluid formula, we must incorporate the patient's body weight. For a patient weighing 64 pounds, which is approximately 29.1 kilograms, the standard formula to estimate the daily maintenance fluids is as follows:

• For the first 10 kg of body weight, provide 100 mL/kg.
• For the next 10 kg of body weight, add 50 mL/kg.
• For every additional kilogram over 20 kg, add 20 mL/kg.

When we apply this formula:

1. The first 10 kg requires 1000 mL (10 kg x 100 mL/kg).
2. The next 10 kg requires 500 mL (10 kg x 50 mL/kg).
3. For the remaining 9.1 kg, we add 182 mL (9.1 kg x 20 mL/kg).

Adding these up: 1000 mL + 500 mL + 182 mL = 1682 mL

Therefore, the closest answer choice to 1682 mL is D) 1650 mL.
