A nurse caring for a client with diabetes insipidus is reviewing laboratory results. What is an expected urinalysis finding?

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: Frequent urination may occur in Cushing’s syndrome due to hyperglycemia-induced osmotic diuresis, but it is not immediately life-threatening. It reflects chronic metabolic changes rather than an acute emergency, so it is less urgent than an irregular pulse, which could indicate a cardiovascular crisis.

Choice B reason: An irregular apical pulse is critical to report immediately in Cushing’s syndrome, as cortisol excess increases cardiovascular risk, including arrhythmias like atrial fibrillation. Irregular pulses may indicate acute cardiac instability, requiring urgent intervention to prevent complications like stroke or heart failure in this high-risk population.

Choice C reason: Dry mucous membranes may suggest dehydration but are not typical in Cushing’s syndrome, which causes fluid retention. Even if present, they are less urgent than an irregular pulse, as dehydration can be managed with fluids, whereas cardiac arrhythmias pose an immediate threat requiring prompt attention.

Choice D reason: Pitting edema in the legs is common in Cushing’s syndrome due to cortisol’s mineralocorticoid effects causing fluid retention. While important, it is a chronic issue manageable with diuretics and not as immediately life-threatening as an irregular pulse, which could indicate acute cardiac complications.
