Correct Answer: A

Rationale: The correct answer is to monitor vital signs post-surgery. Vital signs encompass various parameters like blood pressure, heart rate, respiratory rate, and temperature. Monitoring vital signs helps in early detection of complications such as hemorrhage, infection, or shock. While monitoring the surgical site and incision site are also essential post-surgery, monitoring vital signs takes precedence as it provides a broader assessment of the patient's overall condition. Monitoring blood pressure is part of vital sign assessment and is not the most comprehensive assessment post-surgery.

Correct Answer: B

Rationale: In clients with chronic heart failure, bounding peripheral pulses are a classic sign of fluid overload. This occurs due to increased volume in the arterial system, causing a forceful pulse. Increased urine output (Choice A) is often seen in clients with fluid volume deficit, not overload. Weight loss (Choice C) is also inconsistent with fluid overload as it suggests a fluid deficit. Decreased heart rate (Choice D) is more commonly associated with conditions like bradycardia, hypothyroidism, or the use of certain medications, but not specifically indicative of fluid overload in chronic heart failure.

Correct Answer: A

Rationale: Corrected Rationale: Using a pain rating scale is the most appropriate method to assess a patient's pain level post-surgery. Pain rating scales provide a standardized way for patients to communicate their pain intensity, allowing for accurate assessment and effective pain management. Checking vital signs (choice B) is important for monitoring a patient's overall health status but may not directly reflect their pain level. Observing for non-verbal cues (choice C) is valuable, but it may not always provide a clear indication of the pain intensity. Checking for abnormal breath sounds (choice D) is relevant for assessing respiratory status but does not directly evaluate the patient's pain level.

Correct Answer: C

Rationale: The correct answer is to monitor potassium levels when a patient is receiving furosemide because furosemide can cause potassium depletion. It is essential to monitor potassium levels to prevent complications such as hypokalemia. While monitoring urine output is important in assessing kidney function, and monitoring blood pressure and serum creatinine are relevant in certain situations, the priority when administering furosemide is to monitor potassium levels due to the medication's potential to deplete potassium.

Correct Answer: D

Rationale: The correct action for the nurse to take when caring for a client with deep vein thrombosis is to withhold heparin IV infusion. Administering heparin is crucial in managing deep vein thrombosis by preventing further clot formation. Positioning the affected extremity higher than the heart (Choice A) promotes venous return and reduces swelling. Acetaminophen (Choice B) can be given for pain relief. Massaging the affected extremity (Choice C) is contraindicated as it can dislodge a clot, leading to serious complications.
