Which action would the nurse take first for a patient with a tracheostomy who appears anxious and is having difficulty in coughing up thick respiratory secretion?

A. In SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion), the body retains excessive water, leading to dilutional hyponatremia (low sodium levels). Administering hypertonic saline (3% NS) can exacerbate the condition by rapidly increasing sodium levels, which may cause demyelination of neurons (a condition called osmotic demyelination syndrome). Hypertonic saline is typically only used in severe hyponatremia with neurologic symptoms and should be carefully monitored.
B. Seizure precautions are appropriate in SIADH due to the risk of seizures from severe hyponatremia, which can lead to cerebral edema and neurological compromise.
C. Fluid restriction of 1000 mL/day is appropriate in SIADH to manage the dilutional hyponatremia by preventing further fluid retention.
D. A sodium-restricted diet is also recommended in SIADH to avoid further dilution of sodium levels and prevent worsening of hyponatremia.

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.
