A patient on hemodialysis asks about dietary restrictions. Which of the following foods should the nurse advise the patient to limit?

A. BP of 90/65 is incorrect because blood pressure is a vital sign that can be influenced by many systemic factors. While hypotension or hypertension may affect cerebral perfusion, it is not the most reliable indicator of neurological status.

B. Cranial nerve testing is incorrect because cranial nerve assessment provides useful information about specific neurological functions, but it does not give a global view of the patient’s overall neurological status.

C. PERRLA (pupils equal, round, reactive to light and accommodation) is incorrect because pupil response is an important component of neurological assessment, but changes can be delayed or affected by medications, eye trauma, or other factors. It does not reflect overall brain function as reliably as level of consciousness.

D. Change in level of consciousness is correct because level of consciousness is the most sensitive and reliable indicator of neurological status. Alterations in consciousness often precede other signs of neurological deterioration, making it a key parameter in assessing patients with increased intracranial pressure or other acute neurological conditions. Nurses use tools like the Glasgow Coma Scale to quantify changes in consciousness and detect early deterioration.

A. Strict I&Os is incorrect because monitoring intake and output is essentialin diabetes insipidus (DI). Patients with DI produce large volumes of dilute urine, and careful measurement of fluid balance is critical to detect dehydration and guide fluid replacement therapy.

B. Checking sodium level trends is incorrect because hypernatremia is a common complication of DIdue to excessive water loss. Frequent monitoring of sodium levels allows nurses to detect electrolyte imbalances early and adjust fluids or medications appropriately.

C. Blood pressure monitoring is incorrect because patients with DI are at risk for hypotension secondary to fluid loss and dehydration. Monitoring blood pressure helps assess the patient’s hemodynamic status and response to fluid replacement.

D. Ambulation trial with O2 monitoring is correct because this is not a primary assessment for DI. While ambulation and oxygen monitoring may be indicated for other conditions (e.g., respiratory or cardiac issues), they are not directly related to the pathophysiology or complications of DIand therefore are not a routine part of the nursing assessment for this p
