Which assessment finding for a patient diagnosed with an eating disorder meets criteria for hospitalization?

Choice A reason: A serum potassium level of 3.4 mEq/L is slightly below the normal range (3.5 to 5.0 mEq/L). While it requires monitoring and likely oral supplementation, it is generally not considered an emergency threshold for acute hospitalization unless accompanied by cardiac arrhythmias or much more severe depletion (typically <3.0 mEq/L). Choice B reason: A urine output of 40 mL/hr is within the normal expected range for an adult (minimum 30 mL/hr). This indicates that the patient’s kidneys are currently well-perfused and they are likely not experiencing severe dehydration or acute renal failure, which would be reasons to consider inpatient medical stabilization. Choice C reason: A blood pressure of 100/60 mm Hg is relatively low but may be normal for many young, thin individuals or athletes. Without symptoms of orthostatic hypotension or evidence of end-organ hypoperfusion, this reading alone does not meet the strict medical stability criteria for admission to an inpatient eating disorder unit. Choice D reason: A blood pressure of 78/58 mmHg is severely hypotensive and indicates a state of medical instability. In patients with eating disorders, profound hypotension combined with a low or borderline pulse rate suggests a high risk of cardiovascular collapse. This meets the APA criteria for immediate hospitalization to stabilize vital signs and prevent death.
