A nurse is reviewing a prescription for dexamethasone (Decadron) with a client who has an expanding brain tumor. Which of the following are appropriate statements by the nurse? (Select all that apply.)

Dexamethasone (Decadron) is a corticosteroid commonly prescribed to clients with expanding brain tumors to reduce cerebral edema. By decreasing swelling and inflammation, it helps relieve intracranial pressure and associated neurological symptoms such as headache or vomiting. Corticosteroids, however, are associated with metabolic and fluid retention side effects that require client education. Monitoring and teaching about weight gain, fluid retention, and hyperglycemia are essential to safe therapy.

Rationale for correct answers:

A. “It is given to reduce swelling of the brain.” Dexamethasone decreases cerebral edema and relieves symptoms of increased ICP. This is the primary therapeutic purpose in brain tumor management.

C. “You may notice weight gain.” Corticosteroids can increase appetite and cause fat redistribution, resulting in weight gain. This is a common, expected side effect of therapy.

E. “It can cause you to retain fluids.” Steroids promote sodium and water retention, which can lead to peripheral edema. Clients should be taught to monitor for swelling or sudden weight changes.

Rationale for incorrect answers:
B. “You will need to monitor for low blood sugar.” Dexamethasone can raise, not lower, blood glucose levels. Hyperglycemia is a more likely concern, especially in clients with diabetes.
D. “Tumor growth will be delayed.” Dexamethasone does not affect tumor growth; it only reduces surrounding edema. Definitive tumor treatment requires surgery, radiation, or chemotherapy.

Take home points

• Dexamethasone reduces cerebral edema but does not shrink the tumor itself.
• Weight gain, fluid retention, and hyperglycemia are key side effects requiring education.
• Client teaching helps ensure early recognition of complications during corticosteroid therapy.

Post-cranial surgery care focuses on preventing life-threatening complications, with increased intracranial pressure (ICP) being the most critical concern. A successful recovery is primarily indicated by neurological stability and the absence of ICP-related symptoms, which reflects effective postoperative management. While functional independence and emotional adaptation are important, ensuring brain safety is the top priority for patient outcomes.

Rationale for correct answer:
D. Absence of signs and symptoms of increased ICP: Stable ICP indicates that the brain is not under harmful pressure following surgery. This demonstrates that interventions to manage cerebral edema and promote venous drainage are effective. Achieving this outcome reflects the primary goal of postoperative neurological care.

Rationale for incorrect answers:

A. Ability to return home in 6 days: Discharge timing varies with each patient and is influenced by multiple factors beyond neurological status. Some patients with complications may stay longer, while others may be discharged earlier. Therefore, it is not a reliable indicator of successful surgical outcomes.

B. Ability to meet all self-care needs: Patients may still require assistance with activities of daily living due to weakness or fatigue, even if surgery is successful. Functional independence is a secondary goal and may take weeks to months to achieve. It does not necessarily reflect the immediate success of cranial surgery.

C. Acceptance of residual neurologic deficits: Emotional adaptation is part of long-term rehabilitation but does not indicate the immediate physiological success of surgery. A patient can accept deficits while still experiencing complications like increased ICP. Therefore, acceptance alone is not a measure of successful postoperative outcomes.

Take home points

• Neurological stability and normal ICP are the primary indicators of successful cranial surgery.
• Functional and emotional milestones are important but occur after physiological safety is ensured.
• Early recognition and prevention of ICP elevation are essential to protect brain function.
