At the end of a preoperative teaching session on pain management techniques, a client starts to cry and states, "I just know I can't handle all the pain." Which is the priority nursing problem for this client?

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 C is correct because pushing the undiluted Dextrose slowly through the currently infusing IV is the best way to administer the medication for a client with insulin shock. Insulin shock is a condition in which the blood glucose level drops too low due to excess insulin or insufficient food intake. This can cause symptoms such as confusion, sweating, tremors, or loss of consciousness. The nurse should administer 50% Dextrose IV as a bolus injection to raise the blood glucose level quickly and prevent brain damage.

Choice A is incorrect because asking the pharmacist to add the Dextrose to a TPN solution is not appropriate for a client with insulin shock. TPN stands for total parenteral nutrition, which is a type of intravenous feeding that provides all the nutrients needed by the body. TPN solutions contain dextrose, amino acids, lipids, vitamins, minerals, and electrolytes in specific concentrations and ratios. Adding extra dextrose to a TPN solution can alter its composition and cause complications such as hyperglycemia or fluid overload.

Choice B is incorrect because mixing the Dextrose in a 50 mL piggyback for a total volume of 100 mL is not effective for a client with insulin shock. A piggyback is a type of intravenous infusion that delivers medication through a secondary tubing attached to the primary tubing of another solution. Mixing the Dextrose in a piggyback can dilute its concentration and reduce its potency. It can also delay its delivery and onset of action.

Choice D is incorrect because diluting the Dextrose in one liter of 0.9% Normal Saline solution is not safe for a client with insulin shock. Normal Saline is a type of intravenous fluid that contains sodium chloride in isotonic concentration. Diluting the Dextrose in one liter of Normal Saline can lower its concentration and increase its volume significantly. This can cause complications such as hypoglycemia or fluid overload.
