The nurse in a clinic is reviewing laboratory results for a patient suspected of having undiagnosed diabetes mellitus. Which of the following results would be diagnostic for diabetes?

A. Hypertonic fluids are not contraindicated in patients with cerebral edema. In fact, they are often used to reduce cerebral swelling by drawing fluid out of the brain tissue into the bloodstream.
B. Hypertonic saline (3%) is used to shift fluid out of brain tissue in conditions such as cerebral edema. It creates an osmotic gradient, pulling water from the intracellular space into the extracellular and vascular compartments, reducing intracranial pressure.
C. Hypertonic saline is not used for clients with hypernatremia because it would exacerbate the condition by further increasing sodium levels.
D. Hypertonic fluids do not promote hydration of brain tissue. Instead, they work to reduce excess fluid in the brain by creating an osmotic effect.

A. Encouraging a low-sodium diet is inappropriate for a client with hyponatremia. Hyponatremia is a condition of low sodium levels in the blood, and the priority in managing this condition is to restore normal sodium levels, not to restrict sodium.
B. Padding the side rails of the bed is appropriate to protect the client from injury, especially if the client is at risk for seizures due to the electrolyte imbalance.
C. Providing a quiet and calm environment is beneficial for a client with hyponatremia, as it can help reduce the risk of seizures or agitation associated with the condition.
D. Having the client use the call light when toileting is needed is a standard precaution to ensure the client’s safety, especially if they are at risk of falls or confusion due to the electrolyte imbalance.
