Patient reveals that she induces vomiting as often as a dozen times a day. Which at the following would the nurse expect assessment findings to reveal?

Reasoning: Choice A reason: Hypolipidemia is not a standard finding associated with self-induced vomiting. While malnutrition can affect lipid profiles, it is not an acute or diagnostic marker for purging behavior. The primary concerns in bulimia or purging disorders are electrolyte disturbances rather than changes in circulating lipid concentrations. Choice B reason: Hypercalcemia is not expected in this scenario. In fact, repetitive vomiting is more likely to cause shifts in other electrolytes. Calcium levels are usually maintained within a narrow range unless there is a specific endocrine or bone-related pathology, which is not the primary physiological consequence of frequent emesis. Choice C reason: While tachycardia can occur secondary to dehydration or cardiac arrhythmias, it is a clinical sign rather than a primary laboratory finding. The nurse would prioritize looking for the biochemical cause of potential cardiac instability, which in the context of frequent vomiting, is almost always driven by significant electrolyte depletion. Choice D reason: Frequent self-induced vomiting leads to the direct loss of gastric hydrochloric acid and potassium. This results in hypokalemic metabolic alkalosis. Low potassium (hypokalemia) is a critical finding because it can lead to lethal cardiac arrhythmias, making it the most expected and dangerous assessment finding in this patient.
