A client presents with severe hyperkalemia and cardiac arrhythmias.

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.

Post-operative skin graft care focuses on maximizing graft take by reducing edema and preventing shearing. Knowledge of tissue perfusion and fluid dynamics is necessary to prioritize actions that minimize swelling, which can lift the graft from the bed.

Choice A rationale

Elevating the affected extremity reduces edema at the graft site by promoting venous return. Excessive swelling can separate the new graft from the underlying vascular bed, preventing necessary revascularization and leading to graft failure or necrosis.

Choice B rationale

Inspecting the graft site is important, but the nurse should generally not disturb the initial surgical dressing. Frequent inspection increases the risk of shearing or dislodging the delicate graft before it has successfully adhered to the site.

Choice C rationale

Ensuring the patient does not lie on the graft is a standard intervention to prevent pressure and shearing. However, in the presence of noted edema, elevation is the priority action to ensure the graft remains viable.

Choice D rationale

Administering analgesics addresses the pain level of 6/10, which is important for comfort. However, pain is expected, whereas reducing edema through elevation is functionally more critical to the physiological success and survival of the graft.
