Correct Answer: D

Rationale: The correct action for the nurse to take in this scenario is to discontinue the oxytocin infusion. With contractions occurring every 90 seconds with a duration of 90 seconds, the contractions are too frequent and prolonged, which can lead to uterine rupture or fetal distress. Increasing or maintaining the oxytocin infusion would exacerbate the situation, potentially causing harm to the mother and fetus. Decreasing the oxytocin infusion might not be sufficient to address the issue, making discontinuation the most appropriate action to ensure the safety of both the client and the baby.

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: A

Rationale: The correct answer is A. Clients taking warfarin should avoid leafy green vegetables as they are high in vitamin K, which can reduce the effectiveness of the medication. Therefore, the statement 'I will eat more leafy green vegetables while taking warfarin' indicates a need for further teaching. Choice B is correct as regular monitoring of INR levels is necessary for clients on warfarin. Choice C is correct as grapefruit juice can interact with warfarin and should be avoided. Choice D is correct as using a soft toothbrush is recommended to prevent gum bleeding while on warfarin.

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.
