A nurse in the emergency department is caring for a client who had a seizure and became unresponsive after stating they had a sudden, severe headache. The client's vital signs are as follows: blood pressure of 198/110 mm Hg, pulse of 82/min, respirations of 24/min, and a temperature of 38.2° C (100.8° F). Which of the following neurological disorders should the nurse suspect?

Choice A: Hyperglycemia The reason hyperglycemia is a risk when the prescribed dwell time is not maintained is due to the glucose present in the dialysate. The dialysate used in PD often contains glucose, which acts as an osmotic agent to facilitate fluid removal from the blood. If the dwell time is too short, there may not be enough time for the glucose to be absorbed, leading to higher levels of glucose in the blood. Conversely, if the dwell time is too long, excessive glucose absorption can occur, also leading to hyperglycemia. For patients with diabetes mellitus, maintaining the prescribed dwell time is essential to manage their blood glucose levels effectively. The normal range for fasting blood glucose is typically between 70 to 99 mg/dL, and for diabetes patients, maintaining blood glucose levels as close to the normal range as possible is crucial to prevent complications.

Choice B: Disequilibrium Syndrome Disequilibrium syndrome is characterized by neurological symptoms resulting from rapid changes in the composition of extracellular fluids during dialysis. This condition is more commonly associated with hemodialysis due to the rapid shifts that can occur with this modality. In PD, the risk of disequilibrium syndrome is significantly lower because the exchange of solutes and fluids is more gradual. Therefore, while important to consider, it is not the primary complication associated with the maintenance of dwell time in PD.

Choice C: Peritonitis Peritonitis, an infection of the peritoneal cavity, is a serious complication of PD but is not directly related to the duration of dwell time. It is typically caused by contamination during the exchange process or catheter-related infections. While proper technique and hygiene are critical in preventing peritonitis, the dwell time itself does not influence the risk of developing this infection.

Choice D: Hyperphosphatemia Hyperphosphatemia refers to elevated levels of phosphate in the blood and is a concern in patients with renal failure due to the kidneys’ inability to excrete phosphate effectively. The dwell time in PD may affect the removal of phosphate to some extent; however, it is not the primary concern related to the maintenance of dwell time. Phosphate binders and dietary restrictions are commonly used to manage phosphate levels in PD patients.

Choice A reason: A BUN level of 8 mg/dL and creatinine level of 0.7 mg/dL are within normal ranges and would not be expected in a client with CKD².

Choice B reason: Elevated BUN and creatinine levels, such as 45 mg/dL and 8 mg/dL respectively, are indicative of impaired kidney function, which is consistent with CKD².

Choice C reason: A BUN level of 10 mg/dL and creatinine level of 0.3 mg/dL are lower than the expected values for a client with CKD, indicating better kidney function than typically seen in CKD².

Choice D reason: A BUN level of 23 mg/dL and creatinine level of 1.0 mg/dL may be slightly elevated but are not as indicative of CKD as the values in choice B².
