A nurse is assessing a patient with bulimia nervosa. Which of the following cardiovascular symptoms would the nurse expect to find?
Bradycardia and tachycardia.
Hypertension and mitral valve prolapse.
Orthostatic hypotension and arrhythmias.
Pericardial effusion and cardiomyopathy.
The Correct Answer is C
Choice A rationale:
Bradycardia and tachycardia. While these cardiovascular symptoms can occur in eating disorders, they are more commonly associated with anorexia nervosa rather than bulimia nervosa. Bradycardia (slow heart rate) is often seen in individuals with severe anorexia due to the body's adaptive response to conserve energy. Tachycardia (rapid heart rate) can occur as a compensatory mechanism in response to dehydration and electrolyte imbalances, particularly in those with anorexia. However, in bulimia nervosa, the rapid cycle of binge eating and purging is more likely to lead to electrolyte imbalances that cause other symptoms.
Choice B rationale:
Hypertension and mitral valve prolapse. Hypertension (high blood pressure) is not a common cardiovascular symptom of bulimia nervosa. Mitral valve prolapse, which involves the improper closing of the heart's mitral valve, is also not a typical cardiovascular manifestation of bulimia nervosa. Eating disorders primarily affect the electrical conduction system of the heart and can lead to rhythm disturbances.
Choice C rationale:
Orthostatic hypotension and arrhythmias. This is the correct choice. Orthostatic hypotension, which is a drop in blood pressure upon standing, is a common cardiovascular symptom of bulimia nervosa. It is often a result of dehydration and electrolyte imbalances caused by frequent vomiting and laxative use. Arrhythmias (irregular heart rhythms) can also occur due to electrolyte imbalances, particularly low levels of potassium, which can disrupt the heart's electrical activity.
Choice D rationale:
Pericardial effusion and cardiomyopathy. While pericardial effusion (accumulation of fluid around the heart) and cardiomyopathy (disease of the heart muscle) can occur in individuals with eating disorders, they are not the most common cardiovascular symptoms. These conditions usually result from prolonged malnutrition and severe electrolyte imbalances, which can occur in both anorexia nervosa and bulimia nervosa. However, orthostatic hypotension and arrhythmias are more characteristic of bulimia nervosa.

Correct Answer is A
Explanation
Choice A rationale:
Stabilizing the patient's physical condition. For individuals with severe eating disorders, especially anorexia nervosa, the priority is often to address their physical health and stabilize any medical complications arising from malnutrition. This might involve medical interventions, nutritional rehabilitation, and closely monitoring vital signs to prevent serious health consequences.
Choice B rationale:
Addressing the psychological aspects of the disorder. While addressing the psychological aspects is an integral part of treating eating disorders, it's crucial to prioritize physical health when dealing with severe cases. Malnutrition can lead to various medical complications, including electrolyte imbalances, organ damage, and cardiac issues. Without addressing the physical health first, psychological interventions might be less effective.
Choice C rationale:
Preventing relapse and maintaining recovery. Preventing relapse and maintaining recovery are important aspects of long-term treatment, but they become more relevant after the patient's physical condition has been stabilized. Once the immediate physical risks are minimized, efforts can shift toward addressing psychological factors and developing strategies to prevent relapse.
Choice D rationale:
Providing ongoing follow-up care. Ongoing follow-up care is essential for individuals with eating disorders to ensure that they continue to progress in their recovery journey and to monitor any potential relapse signs. However, this becomes more pertinent once the patient's physical condition has been stabilized and initial treatment has been provided.
Correct Answer is A
Explanation
Eating until feeling uncomfortably full.
Choice A rationale:
Eating until feeling uncomfortably full is a characteristic of binge eating disorder. Binge eating involves consuming an excessive amount of food within a discrete period while feeling a lack of control over eating. This often results in physical discomfort due to the large quantity of food consumed.
Choice B rationale:
Recurrent episodes of binge eating followed by inappropriate compensatory behaviors are more characteristic of bulimia nervosa, not binge eating disorder. In binge eating disorder, there is no consistent use of inappropriate compensatory behaviors such as vomiting or excessive exercise to counteract the binge episodes.
Choice C rationale:
Eating more rapidly than normal can be a characteristic of binge eating episodes, but it is not a defining feature of binge eating disorder. Binge eating disorder is primarily characterized by the consumption of large amounts of food within a short period and the sense of lack of control during these episodes.
Choice D rationale:
Recurrent episodes of night eating is not a characteristic of binge eating disorder. Night eating disorder is a separate condition characterized by consuming a significant portion of daily caloric intake during the nighttime hours.
