A patient's status post hypophysectomy had drainage on the mustache dressing. Which complication is this patient at risk for if the glucose level of the drainage is 50 mg/dL?

A. "Test your blood glucose level every 8 hours.": This is incorrect. During illness, blood glucose levels should be checked more frequently, typically every 2 to 4 hours, to closely monitor for hyperglycemia and prevent diabetic ketoacidosis (DKA). Checking every 8 hours may not be frequent enough, especially if the client is ill or experiencing stress, both of which can affect blood sugar.
B. "Check your urine for ketones when blood glucose levels are greater than 240 mg/dL.": This is the correct instruction. When blood glucose levels exceed 240 mg/dL, it is important to check for ketones in the urine. The presence of ketones can indicate the development of DKA, and early detection can prevent the condition from worsening.
C. "Withhold your usual daily dose of insulin.": This is incorrect. Insulin should never be withheld during periods of illness unless specifically instructed by a healthcare provider. Withholding insulin can increase the risk of DKA, as the body will continue to break down fat for energy in the absence of insulin, leading to ketosis.
D. "Drink 240 to 360 milliliters of calorie-free liquids every 8 hours.": This is not entirely correct. While staying hydrated is important, the recommendation is generally to drink more frequently, ideally 8 ounces of fluid every hour to stay well-hydrated. It is also recommended to drink fluids that contain some carbohydrates (such as electrolyte-containing drinks) to help manage blood glucose levels during illness.

A. Monitor for postural hypotension: This is unlikely in Cushing’s syndrome, where hypertension (not hypotension) is more common due to excess cortisol and fluid retention.
B. Assess blood glucose level: Hyperglycemia is common in Cushing’s syndrome due to the effects of cortisol on glucose metabolism, so monitoring blood glucose levels is essential.
C. Monitor for an irregular heart rate: While Cushing's syndrome can lead to electrolyte imbalances that may affect heart rhythm, this is not a primary intervention in Cushing's syndrome. Monitoring for hypertension and fluid retention is more critical.
D. Assess for neck vein distention: Elevated cortisol levels can lead to fluid retention and hypertension, contributing to neck vein distention, so this is an important observation.
E. Weigh the client daily: Fluid retention and weight gain are key features of Cushing's syndrome, so daily weight monitoring helps assess fluid status and detect rapid weight gain indicative of worsening symptoms.
