Jo is a client with Type 1 Diabetes. Jo has a blood glucose level of 644 mg/dL. The nurse interprets that this client is most at risk of developing which type of acid-base imbalance?

Choice A reason: A 68-year-old patient with type 2 diabetes who has peripheral neuropathy and complains of burning foot pain is not the most urgent patient to assess. Peripheral neuropathy is a complication of diabetes that affects the nerves, especially in the feet and legs. It can cause symptoms such as numbness, tingling, burning, or pain. The nurse should assess the patient's foot condition, provide pain relief, and educate the patient on foot care. However, this patient is not in immediate danger, and can wait until the nurse finishes assessing the more critical patient.

Choice B reason: A 35-year-old patient with type 1 diabetes whose most recent blood glucose reading was 230 mg/dL is not the most critical patient to assess. Type 1 diabetes is a condition where the pancreas does not produce any insulin, a hormone that helps the cells use glucose for energy. Patients with type 1 diabetes need to take insulin injections or use an insulin pump to control their blood glucose level. A blood glucose reading of 230 mg/dL is above the normal range of 70 to 130 mg/dL before meals, and indicates hyperglycemia (high blood sugar). The nurse should check the patient's insulin dose, monitor the patient's symptoms, and provide education on blood glucose management. However, this patient is not in life-threatening condition, and can wait until the nurse attends to the more serious patient.

Choice C reason: A 60-year-old patient with hyperosmolar hyperglycemic syndrome with dry oral mucosa and low urine output is the most important patient to assess. Hyperosmolar hyperglycemic syndrome (HHS) is a severe complication of diabetes that occurs when the blood glucose level is extremely high, usually above 600 mg/dL. HHS can cause dehydration, electrolyte imbalance, and coma. Dry oral mucosa and low urine output are signs of dehydration, which can lead to shock and organ failure. The nurse should assess the patient's vital signs, blood glucose level, fluid and electrolyte status, and neurological function. The nurse should also administer intravenous fluids, insulin, and electrolytes as prescribed by the health care provider. This patient is in a medical emergency, and needs immediate intervention.

Choice D reason: A 19-year-old patient with type 1 diabetes who was admitted with possible dawn phenomenon is not the most acute patient to assess. Dawn phenomenon is a condition where the blood glucose level rises in the early morning, usually between 2:00 AM and 8:00 AM. This is due to the release of hormones that increase the blood glucose level, such as growth hormone, cortisol, and glucagon. The nurse should review the patient's blood glucose records, adjust the insulin dose or timing, and provide education on how to prevent or manage the dawn phenomenon. However, this patient is not in a critical situation, and can wait until the nurse evaluates the more unstable patient.

Choice A reason: Performing an in/out catheterization is not a suitable method to measure urine output for a 10-month old client with dehydration. An in/out catheterization is a procedure where a catheter is inserted into the bladder through the urethra, and the urine is drained and measured. This method is invasive, painful, and carries the risk of infection and trauma. It is usually reserved for clients who have urinary retention or obstruction, or who need a sterile urine sample.

Choice B reason: Inserting a Foley catheter is also not an appropriate method to measure urine output for a 10-month old client with dehydration. A Foley catheter is a type of catheter that stays in the bladder and drains the urine into a collection bag. This method is also invasive, painful, and carries the risk of infection and trauma. It is usually used for clients who have urinary incontinence, surgery, or long-term bed rest.

Choice C reason: Collecting the client's urine in a cup is not a feasible method to measure urine output for a 10-month old client with dehydration. A cup is not a reliable or accurate device to collect and measure urine, especially for a young child who may not be toilet trained or cooperative. It is also difficult to ensure that all the urine is collected in the cup, and that the cup is not contaminated by other fluids or substances.

Choice D reason: Counting the number of wet diapers is the best method to measure urine output for a 10-month old client with dehydration. This method is non-invasive, simple, and practical. It can provide an estimate of the urine volume and frequency, and indicate the hydration status of the child. The nurse should weigh the diapers before and after use, and record the difference in grams. One gram of weight equals one milliliter of urine. The nurse should also observe the color, odor, and concentration of the urine. The normal urine output for a child is 1 to 2 mL/kg/hour.
