Final answer:
Post-hemodialysis, a nurse checks the patient's vital signs and weight to assess hemodynamic stability and the effectiveness of fluid removal. Vital signs offer immediate insights into the patient's hemodynamic state, while changes in weight can indicate fluid loss.
Step-by-step explanation:
A client with chronic renal failure has completed a hemodialysis treatment. To monitor for hemodynamic stability and to determine the effectiveness of fluid extraction after the treatment, the nurse would typically measure the patient's vital signs and weight. The measurement of vital signs is essential for assessing the patient's stability in terms of blood pressure, heart rate, respiratory rate, and temperature. In contrast, the weight measurement is indicative of fluid loss or retention following the hemodialysis procedure. Other parameters such as blood urea nitrogen (BUN), sodium and potassium levels, and creatinine levels are also critical for evaluating kidney function but might not be measured immediately post-hemodialysis for hemodynamic stability and fluid extraction effectiveness.
