An intubated client with increased intracranial pressure has pooled secretions in the airway.
Which action should the nurse take first?

Step 1 is (1 unit ÷ 10 units) × 100 mL.

Step 2 is 0.1 × 100 mL.

Step 3 is 10 mL.

Rationale for correct condition hemorrhagic stroke is strongly indicated by the "worst headache of my life," sudden aphasia, and left-sided weakness. an inr of 4.9 is critically high, significantly increasing bleeding risk. negative kernig and brudzinski signs help rule out meningitis despite the fever history. the presence of photophobia and vision loss further supports an intracranial event.

Rationale for correct actions a stat ct brain is the gold standard to differentiate between ischemic and hemorrhagic events and identify intracranial bleeding. a lumbar puncture may be indicated if the ct is negative but clinical suspicion of subarachnoid hemorrhage remains high. these actions are time-sensitive to prevent secondary brain injury from increased intracranial pressure. normal inr for a client not on anticoagulants is 0.8-1.1. the nurse must prioritize diagnostic imaging to guide surgical or medical intervention. these steps address the acute neurological deficit and high-intensity headache.

Rationale for correct parameters blood pressure must be monitored strictly as hypertension can exacerbate intracranial bleeding and worsen stroke outcomes. the client's blood pressure rose from 119/85 to 159/83 mm hg, indicating a need for tight control. monitoring pt/inr is vital due to the supratherapeutic level of 4.9, which necessitates reversal agents like vitamin k or fresh frozen plasma. normal prothrombin time is typically 11-13.5 seconds. managing these parameters prevents further hematoma expansion. frequent neurological checks are also implicit in monitoring these physiological markers.

Rationale for incorrect conditions migraine headache does not typically present with sudden aphasia, hemiparesis, or an inr of 4.9. trigeminal neuralgia is characterized by stabbing facial pain, which the client explicitly denied. meningitis is unlikely given the negative kernig and brudzinski signs and the sudden, focal neurological deficits. while the client had a fever, the clinical picture is dominated by vascular and neurological collapse.

Rationale for incorrect actions administering sumatriptan is contraindicated in suspected stroke as it causes vasoconstriction and is intended for migraines. carbamazepine is the specific treatment for trigeminal neuralgia, which does not match this client's presentation. providing ibuprofen or other anticoagulants would be dangerous given the already elevated inr of 4.9.

Rationale for incorrect parameters a headache diary for food triggers is a long-term management tool for migraine headache, not an acute stroke. temperature monitoring is less critical than hemodynamics in the immediate management of a suspected hemorrhage. while the wbc is slightly elevated, it is expected with a uti and is less urgent than the neurological crisis.
