The following vignette applies to the next 2 items.
An 83-year-old woman is admitted to a nursing home for ongoing management of Parkinson disease. Her husband can no longer care for her at home because she is moderately demented, has difficulty walking, has fallen several times and has urinary incontinence. She has difficulty swallowing her pills, and she needs assistance with feeding. Despite her husband's attentive care, she has lost 9 kg (20 lb), going from 47.1 kg (104 lb) to 38 kg (84 lb) during the past 9 months. After 2 weeks in the nursing home, the nursing staff notes that the patient frequently eats and drinks very little and often coughs after she swallows. Her current medications include fluoxetine, selegiline, carbidopa-levodopa, trazodone, estrogen and sorbitol. Vital signs now are: temperature 36.4°C (97.6°F), axillary; pulse 88/min; respirations 18/min and blood pressure 102/84 mm Hg, supine. Physical examination shows a frail and thin woman. Voice is soft and low. Chest is clear to auscultation. Heart rate is regular without murmurs or gallops. Abdomen is soft and nontender with decreased bowel sounds. Rectal examination is normal. She is generally stiff with low amplitude tremors at rest. Laboratory results show:
Serum
BUN
47 mg/dL
Creatinine
1.9 mg/dL
Na+
161 mEq/L
K+
3.9 mEq/L
Cl-
120 mEq/L
HCO3-
24 mEq/L
When the nursing home calls you with the laboratory results, the office staff informs you that the patient's husband telephoned earlier that afternoon and "fired" you from the case. There are no written notes from the staff and you have not spoken to the husband yourself.

Item 1: E.
Confused B and E, but E is prefered. She had pre-renal failure of contract volume (BUN/Creatinine > 20 and high Creatinine) more often in elderly who is characterized by disoreded thirst or neglect (this case is the former) and resultant hypernatremia. Therefore, patient requires to be hospitalized to carry out fluid challenge (if not be promtly, tubular necrosis is coming) and hypernatremia condition is very strictly under control. However, B option is also fair for subtle work ethic. Not sure. How about your idea?
