The nurse providing care for a client with Cushing syndrome has identified the nursing diagnosis of risk for injury related to weakness. How should the nurse best reduce this risk?

Reasoning:

Choice A reason: Aspiration precautions are important in head injury to prevent pneumonia, particularly if consciousness is impaired, but they are not specific seizure prophylactic measures. Seizures require anticonvulsants to prevent neuronal hyperexcitability, making aspiration precautions a secondary concern unrelated to seizure prevention.

Choice B reason: Anticonvulsant medications, initiated early (e.g., day two), are standard for seizure prophylaxis in head injury. Trauma can cause cortical irritation, increasing seizure risk. Drugs like levetiracetam stabilize neuronal activity, preventing seizures, which could worsen brain injury or ICP, making this the primary measure.

Choice C reason: Intubation and ventilator support are used for severe head injuries with compromised airway or breathing but are not seizure prophylaxis. Seizures are managed with anticonvulsants, as mechanical ventilation does not address neuronal excitability, making this inappropriate for seizure prevention.

Choice D reason: Antiemetic medications manage nausea but are not seizure prophylactic measures. While vomiting may occur post-head injury, it does not prevent seizures, which result from cortical irritability. Anticonvulsants directly target seizure risk, making antiemetics irrelevant to this specific intervention goal.

Reasoning:

Choice A reason: DIC is not primarily an autoimmune disease complication. While autoimmune conditions may trigger inflammation, DIC results from widespread activation of coagulation pathways due to conditions like sepsis or trauma, leading to microthrombi and factor consumption, not direct autoimmune attack on body cells.

Choice B reason: Hemolytic processes destroying erythrocytes cause hemolytic anemia, not DIC. While hemolysis may contribute to inflammation, DIC is driven by systemic activation of coagulation, forming microthrombi that consume platelets and clotting factors, leading to bleeding, not primarily erythrocyte destruction.

Choice C reason: Immune-mediated platelet destruction occurs in conditions like immune thrombocytopenia, not DIC. DIC involves systemic clotting activation, consuming platelets and factors, causing both thrombosis and bleeding. The immune system does not directly target platelets in DIC’s pathophysiology, making this explanation inaccurate.

Choice D reason: DIC is caused by abnormal activation of the clotting pathway, triggered by conditions like sepsis or trauma, leading to excessive microthrombi formation in organs. This consumes platelets and clotting factors, causing bleeding tendencies.
