Correct Answer: C

Rationale: An elevated CVP and sudden weight gain indicate fluid overload, which can strain the heart. Auscultating for an irregular heart rate is crucial as electrolyte imbalances and fluid shifts after burns can lead to cardiac complications. Monitoring the heart rate is a priority to detect any cardiac distress early. While reviewing urine output and administering diuretics are important interventions, they should come after ensuring the client's cardiac status is stable. Increasing oral fluid intake may exacerbate the fluid overload, making it an inappropriate intervention in this scenario.

Correct Answer: D

Rationale: Encouraging clients with paranoia to express their concerns and validating their feelings is crucial as it helps establish trust and reduce anxiety. This approach also aids in building a therapeutic relationship. Reassuring the client that their fears are unfounded (Choice A) may invalidate their feelings and worsen trust. Placing the client in a private room to reduce stimuli (Choice B) may be helpful in some situations but does not address the underlying issue of paranoia. Providing a distraction (Choice C) may temporarily shift the client's focus but does not address the root cause of the paranoia. Therefore, the priority intervention is to encourage the client to express their concerns and validate their feelings.

Correct Answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.

Correct Answer: D

Rationale: The correct answer is D: Notify the healthcare provider immediately. A drop in platelet count during heparin therapy may indicate heparin-induced thrombocytopenia (HIT), a serious condition that increases the risk of clot formation. Immediate discontinuation of heparin is necessary to prevent further complications. Administering platelet transfusion without addressing the underlying cause can be harmful. Continuing to monitor the platelet count without taking immediate action can lead to delayed intervention. Notifying the healthcare provider promptly allows for assessment and initiation of alternative anticoagulation therapy to manage the client's condition effectively.

Correct Answer: B

Rationale: An increase in urine output is a reliable indicator that the client's hydration status is improving. This reflects adequate fluid replacement and improved kidney function. Choice A is subjective and may not always indicate improved hydration. Choice C, while a positive sign, may be influenced by other factors such as medications or pain. Choice D, skin turgor returning to normal, is a delayed indicator of hydration status and may take time to improve even after hydration is initiated.
