Which laboratory results should the nurse closely monitor in a client who has end-stage renal disease (ESRD.?

Choice C is correct because serum potassium, calcium, and phosphorus are electrolytes that can be affected by ESRD. ESRD is a condition in which the kidneys lose their ability to filter waste products and excess fluids from the blood. This can cause electrolyte imbalances that can lead to serious complications, such as cardiac arrhythmias, bone disorders, or metabolic acidosis. The nurse should closely monitor these electrolytes and report any abnormal values.

Choice A is incorrect because blood pressure, heart rate, and temperature are vital signs that are not specific to ESRD. Vital signs can be influenced by many factors and may not reflect the severity of kidney damage. The nurse should monitor vital signs regularly, but not as closely as electrolytes.

Choice B is incorrect because leukocytes, neutrophils, and thyroxine are not laboratory results that are directly related to ESRD. Leukocytes and neutrophils are types of white blood cells that are involved in immune response and inflammation. Thyroxine is a hormone that regulates metabolism and growth. These laboratory results may be altered by other conditions or medications, but not by ESRD.

Choice D is incorrect because erythrocytes, hemoglobin, and hematocrit are laboratory results that measure the red blood cell count and oxygen-carrying capacity of the blood. These laboratory results may be decreased in ESRD due to anemia, which is a common complication of chronic kidney disease. However, anemia is not as life-threatening as electrolyte imbalances and can be treated with erythropoietin injections or iron supplements.

Choice A: Obtaining postoperative vital signs for a client one day following unilateral knee arthroplasty is a nursing action that the nurse can assign to the PN, as this is a basic skill that does not require complex judgment or intervention by the registered nurse. Therefore, this is a correct choice.

Choice B: Starting the second blood transfusion for a client twelve hours following a below knee amputation is not a nursing action that the nurse should assign to the PN, as this is an advanced skill that requires close monitoring and evaluation by the registered nurse. This is an incorrect choice.

Choice C: Initiating patient controlled analgesia (PCA. pumps for two clients immediately postoperatively is not a nursing action that the nurse should assign to the PN, as this involves administering controlled substances and assessing pain levels, which are beyond the scope of practice of the PN. This is another incorrect choice.

Choice D: Performing daily surgical dressing change for a client who had an abdominal hysterectomy is a nursing action that the nurse can assign to the PN, as this is a routine task that can be done under the supervision and direction of the registered nurse. Therefore, this is another correct choice.

Choice E: Administering a dose of insulin per sliding scale for a client with type 2 diabetes mellitus (DM) is a nursing action that the nurse can assign to the PN, as this is an established protocol that can be followed by the PN with appropriate documentation and reporting. Therefore, this is another correct choice.
