A client is receiving continuous ambulatory peritoneal dialysis since the arteriovenous (AV) graft in the right arm is no longer available for use for hemodialysis. The client has lost weight, has increasing peripheral edema, and has a serum albumin level of 1.5 g/dL (15 g/L). Which intervention is the priority for the nurse to implement?

Serum Albumin Reference Range: 3.5 to 5.5 g/dL (35 to 55 g/L)

Choice A reason: Remove the catheter and palpate the client's bladder for residual distention. This is not the best action, as it may cause discomfort and trauma to the client. The catheter should not be removed until the bladder is fully emptied or up to 1,000 mL of urine is drained, as removing it too soon may cause urinary retention or infection.

Choice B reason: Remove the catheter and replace with an indwelling catheter. This is not the best action, as it may cause unnecessary exposure and trauma to the client. The catheter should not be replaced unless ordered by the healthcare provider, as replacing it may increase the risk of infection or urethral injury.

Choice C reason: Allow the bladder to empty completely or up to 1,000 mL of urine. This is the best action, as it can prevent bladder spasms, overdistention, or rupture. The nurse should monitor the urine output and color, and document the amount and characteristics of urine drained.

Choice D reason: Clamp the catheter for thirty minutes and then resume draining. This is not the best action, as it may cause pain and discomfort to the client. The catheter should not be clamped unless ordered by the healthcare provider, as clamping it may increase the risk of infection or bladder damage.

Choice A reason: Blood pressure, heart rate, and temperature are vital signs that should be monitored in any client, but they are not laboratory results. ESRD can cause hypertension and cardiovascular complications, so blood pressure and heart rate should be controlled with medications and lifestyle modifications. Temperature should be monitored for signs of infection or inflammation.

Choice B reason: Leukocytes, neutrophils, and thyroxine are not specific laboratory results for ESRD. Leukocytes and neutrophils are types of white blood cells that indicate immune system activity and infection. Thyroxine is a thyroid hormone that regulates metabolism and growth. ESRD can affect the immune system and the thyroid function, but these are not the primary indicators of renal function.

Choice C reason: This is the correct answer because serum potassium, calcium, and phosphorus are important laboratory results for ESRD. ESRD can cause electrolyte imbalances that can affect the heart, muscles, nerves, and bones. Serum potassium can increase due to reduced renal excretion and cause cardiac arrhythmias and muscle weakness. Serum calcium can decrease due to impaired absorption and activation of vitamin D and cause muscle cramps, tetany, and osteoporosis. Serum phosphorus can increase due to reduced renal excretion and cause soft tissue calcification and bone pain.

Choice D reason: Erythrocytes, hemoglobin, and hematocrit are laboratory results that measure red blood cell count, oxygen-carrying capacity, and blood volume. ESRD can cause anemia due to reduced production of erythropoietin, a hormone that stimulates red blood cell formation in the bone marrow. Anemia can cause fatigue, pallor, shortness of breath, and chest pain. However, these are not the most significant laboratory results for ESRD.
