To prevent the most common serious complication of peritoneal dialysis, it is important for the nurse to:

Choice A reason: Medicating the patient for pain is not the most appropriate immediate action in this situation. While pain management is important, the primary concern should be addressing the significant changes in heart rate and blood pressure, which may indicate a more serious underlying issue.

Choice B reason: Allowing the patient to rest quietly is not the appropriate response to the noted changes in vital signs. The increase in heart rate and drop in blood pressure are signs that require immediate investigation and intervention, rather than passive observation.

Choice C reason: Assessing the patient for bleeding is the most appropriate action. The increase in heart rate and decrease in blood pressure following an angioplasty procedure are concerning for potential bleeding or hemorrhage, especially if the patient has an intra-arterial line. Quick assessment and intervention are crucial to address any bleeding and stabilize the patient's condition.

Choice D reason: Documenting the findings in the chart is necessary, but it should not be the immediate priority. The nurse must first assess and address the potential cause of the changes in vital signs, such as bleeding, before documenting the events.

Choice A reason: Obtaining daily weights of the client is the best action to assess the therapeutic effect of furosemide in managing early chronic kidney disease. Daily weights provide valuable information about fluid balance and the effectiveness of the diuretic in reducing fluid retention. Consistent weight monitoring helps determine if the medication is achieving its goal of managing fluid overload, which is a common issue in CKD patients.

Choice B reason: Assessing acid-base balance is important in managing CKD, but it is not the primary action to assess the therapeutic effect of furosemide. While diuretics can influence electrolyte levels and acid-base balance, monitoring fluid status through daily weights is more directly related to evaluating the effectiveness of the medication.

Choice C reason: Assessing the client's serum creatinine is crucial for monitoring kidney function and progression of CKD. However, it is not the primary action to determine the therapeutic effect of furosemide. The focus of furosemide therapy is to manage fluid balance, and daily weights provide a more immediate and relevant assessment of this effect.

Choice D reason: Auscultating heart sounds is part of a comprehensive assessment of a CKD patient, but it is not the best action to evaluate the therapeutic effect of furosemide. Heart sounds can provide information about cardiac function and potential complications, but they do not directly measure the effectiveness of fluid management achieved by the diuretic.
