A nurse is assisting with the care of a client who has hypertension and chronic kidney disease. The client is scheduled for hemodialysis. Which of the following actions should the nurse plan to take while caring for this client? (Select all that apply.)

A. Obtain the client's weight.: Pre-dialysis weight is essential to determine the "fluid gain" since the last treatment and to calculate the necessary ultrafiltration goal. Comparing this to the client's "dry weight" allows for a safe and individualized fluid removal plan. This measurement is the most objective indicator of the patient's interdialytic fluid retention. B. Administer a sedative to the client.: Sedatives can cause respiratory depression and hypotension, which complicates the hemodynamic monitoring required during hemodialysis. Maintaining a clear sensorium is vital for the client to report symptoms like cramping or dizziness during the procedure. Pharmacological sedation is not a routine part of preoperative care for stable dialysis sessions. C. Check the graft site for a palpable thrill.: Assessing for a thrill (vibration) and a bruit (whooshing sound) confirms the patency of the arteriovenous access. The absence of these findings indicates a potential thrombosis or stenosis, which would prevent the initiation of dialysis. Ensuring access viability is a critical safety step before any needle cannulation occurs. D. Verify the glomerular filtration rate.: While the glomerular filtration rate is used to diagnose chronic kidney disease, it is not an action performed immediately before a dialysis session. In end-stage disease, this value is consistently low (typically < 15 ml/min) and does not dictate the immediate parameters of a single treatment. The focus is on fluid and electrolyte status rather than GFR. E. Document vital signs.: Establishing a baseline for blood pressure, heart rate, and temperature is mandatory to monitor the client's tolerance to the procedure. Hemodialysis causes significant fluid shifts that can lead to rapid hemodynamic instability. Frequent vital sign checks allow the nurse to intervene promptly if the client becomes hypotensive or tachycardic.
