A client with a diagnosis of valvular heart disease is being considered for mechanical valve replacement. Which circumstance is essential to assess before the surgery is performed?
The ability to comply with anticoagulant therapy for life.
The likelihood of the client experiencing body image problems.
The physical demands of the client’s lifestyle.
The ability to participate in a cardiac rehabilitation program.
The Correct Answer is A
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.

Correct Answer is A
Explanation
Choice A rationale
The weights from the traction device should only be removed if the client develops a life- threatening situation. This is to ensure the client’s immediate safety and address the critical condition.
Choice B rationale
The client should not have the weights removed for repositioning in the bed. Proper techniques should be used to reposition the client without removing the weights to maintain the effectiveness of the traction.
Choice C rationale
Complaints of pain should be addressed by assessing the cause and providing appropriate pain management, but the weights should not be removed as it can compromise the traction.
Choice D rationale
The weights should not be removed for an x-ray. The traction can be maintained during imaging procedures to ensure continuous treatment.
Correct Answer is ["325"]
Explanation
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.
