The nurse in the emergency department is caring for a client who has fallen 20 feet from a roof. While performing the primary assessment, what is the most important nursing intervention?

A. Call the health care provider if stools are tarry: This instruction is more relevant to medications such as aspirin or NSAIDs, which can increase the risk of gastrointestinal bleeding.
Clopidogrel, while also an antiplatelet medication, is less likely to cause gastrointestinal bleeding compared to aspirin.

B. Clopidogrel will reduce cerebral artery plaque formation: Clopidogrel is an antiplatelet
medication that inhibits platelet aggregation, thereby reducing the formation of blood clots and potentially slowing the progression of atherosclerosis by preventing further plaque formation.

C. Clopidogrel will dissolve clots in the cerebral arteries: While clopidogrel can help prevent the formation of new clots, it does not actively dissolve existing clots in the cerebral arteries. Its primary mechanism of action is to inhibit platelet aggregation and prevent clot formation.

D. Monitor and record the blood pressure daily: While monitoring blood pressure is important for managing cerebral atherosclerosis and reducing the risk of stroke, it is not directly related to the action of clopidogrel. Blood pressure management may involve lifestyle modifications and other medications but is not specific to clopidogrel administration.

A. Slurred speech: This can be a sign of increased ICP but is not typically considered a late sign. It is more often associated with early or moderate increases in ICP when the brain is starting to experience pressure but is not yet at a critical stage.
B. Bradycardia: This is a late sign of increased ICP and is part of Cushing's triad, which includes bradycardia, irregular respirations, and a widened pulse pressure. Bradycardia occurs as a compensatory mechanism to decrease the cerebral blood flow in response to increased ICP.
C. Hypotension: While changes in blood pressure can be associated with ICP, hypotension is not typically a late sign of increased ICP. In fact, hypertension with a widened pulse pressure would be more indicative of increased ICP as part of Cushing's triad.
D. Nonreactive dilated pupils: This is a late sign of increased ICP and indicates brain stem herniation or compression, which is a medical emergency. The pupils become fixed and dilated as the oculomotor nerve is compressed due to increased pressure.
E. Confusion: Confusion can be an early sign of increased ICP as it indicates changes in mental status. However, it is not specifically a late sign of increased ICP, as it can occur at various stages of pressure changes within the brain.
