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 A

Explanation

Choice A rationale

The ability to comply with anticoagulant therapy for life is essential for clients undergoing mechanical valve replacement. Mechanical valves are prone to thrombus formation, which can lead to serious complications such as stroke. Therefore, lifelong anticoagulation therapy is necessary to prevent clot formation on the valve.

Choice B rationale

While body image problems may arise due to surgical scars or the presence of a mechanical valve, they are not a primary concern that needs to be assessed before surgery. The focus should be on the client’s ability to manage the medical requirements post-surgery.

Choice C rationale

The physical demands of the client’s lifestyle are important but not as critical as the ability to comply with anticoagulant therapy. The primary concern is ensuring the client can adhere to the necessary medical regimen to prevent complications.

Choice D rationale

Participation in a cardiac rehabilitation program is beneficial for recovery and improving cardiovascular health, but it is not as crucial as the ability to comply with anticoagulant therapy. The main priority is preventing thrombus formation on the mechanical valve.

A. “Does drinking coffee or ingesting chocolate seem related to the episodes?” B. “Does being exposed to heat seem to cause the episodes?” C. “Do the signs and symptoms occur while you are asleep?” D. “Have you experienced any injuries that have limited your activity levels lately?”

Correct Answer is A

Explanation

Choice A rationale

Drinking coffee or ingesting chocolate can trigger Raynaud’s disease symptoms. Both caffeine and chocolate can cause vasoconstriction, which can exacerbate the symptoms of Raynaud’s disease.

Choice B rationale

Being exposed to heat is not a common trigger for Raynaud’s disease. The condition is typically triggered by cold temperatures or stress.

Choice C rationale

Symptoms of Raynaud’s disease do not typically occur while asleep. The condition is more likely to be triggered by cold or stress during waking hours.

Choice D rationale

Injuries that limit activity levels are not directly related to the triggers of Raynaud’s disease. The primary triggers are cold temperatures and stress.
