A nurse is preparing to start an IV infusion of lactated Ringer’s for a client who sustained a burn injury.

The client is prescribed 5,200 mL of fluid over the first 24 hr. How many mL/hr should the nurse set the pump to infuse for the first 8 hr? (Round the answer to the nearest whole number.

Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["325"]

Step 1 is to determine the total volume of fluid to be infused in the first 8 hours. According to the Parkland formula for fluid resuscitation, half of the prescribed volume is administered in the first 8 hours. Thus:

Total fluid for the first 8 hours = 5,200 mL ÷ 2 = 2,600 mL.

Step 2 is to calculate the infusion rate in mL/hr for the first 8 hours. Divide the total volume for the first 8 hours by the total time in hours:

Infusion rate = 2,600 mL ÷ 8 hr = 325 mL/hr.

Final calculated answer: 325 mL/hr.

Correct Answer is B

Explanation

Choice A rationale

Avoid handwashing after eating. This statement is incorrect. Handwashing is a critical preventive measure to reduce the risk of viral hepatitis, especially after eating or using the restroom.

Choice B rationale

Avoid foods prepared with tap water. This statement is correct. In areas where the water supply may be contaminated, it is essential to avoid foods prepared with tap water to reduce the risk of viral hepatitis, particularly hepatitis A, which can be transmitted through contaminated food and water.

Choice C rationale

Avoid eating meat. This statement is incorrect. While it is essential to ensure that meat is cooked thoroughly to prevent foodborne illnesses, avoiding meat altogether is not a specific preventive measure for viral hepatitis.

Choice D rationale

Avoid covering sores with bandages. This statement is incorrect. Covering sores with bandages can help prevent the spread of infections, including viral hepatitis, by reducing the risk of contact with infectious fluids.

A. Dextrose 5% in water. B. 0.45% sodium chloride. C. Dextrose 5% in 0.9% sodium chloride. D. Lactated Ringers.

Correct Answer is D

Explanation

Choice A rationale

Dextrose 5% in water is not recommended for initial fluid resuscitation in burn patients because it does not provide the necessary electrolytes to address the fluid shifts and electrolyte imbalances that occur after a burn injury.

Choice B rationale

0.45% sodium chloride is a hypotonic solution and is not suitable for initial fluid resuscitation in burn patients. It can lead to cellular swelling and does not adequately replace the lost extracellular fluid.

Choice C rationale

Dextrose 5% in 0.9% sodium chloride is not the preferred choice for initial fluid resuscitation in burn patients. While it provides both glucose and electrolytes, it is not as effective as Lactated Ringers in addressing the specific needs of burn patients.

Choice D rationale

Lactated Ringers is the recommended fluid for initial resuscitation in burn patients. It is an isotonic solution that helps to restore circulating volume, correct electrolyte imbalances, and prevent hypovolemic shock.
