TNCC Practice Test for Trauma Nurse Core Course – Exam Prep & Study Guide

To determine the appropriate amount of intravenous (IV) fluids to administer based on a 19% total body surface area (TBSA) burned for a 120 kg male, it's important to apply the Parkland formula. This formula is used to calculate fluid resuscitation requirements for burn patients in the initial stages after injury.

The Parkland formula suggests calculating the fluid requirement based on the following parameters:

1. **Total body weight in kg**: In this case, the patient weighs 120 kg.

2. **TBSA burned**: Here, it is 19%.

The formula is:

**Fluid requirement (in mL) = 4 mL x % TBSA burned x patient's weight in kg**.

Plugging in the numbers:

- 4 mL x 19% TBSA x 120 kg = 4 x 0.19 x 120 = 9120 mL for 24 hours.

Since this total is for the first 24 hours, the volume to be administered in the first 8 hours is half of this amount, as the fluids are given at a rate of 50% in the first 8 hours after the burn:

9120 mL / 2 = 4560
