Which of the following is a priority intervention for a patient with bulimia nervosa who is experiencing electrolyte imbalances?
Correct Answer: B
Rationale: The correct answer is B. Monitoring the patient's heart rate and electrolyte levels closely is crucial in managing electrolyte imbalances in patients with bulimia nervosa. Electrolyte imbalances, often caused by purging behaviors, can lead to serious complications like cardiac arrhythmias. Close monitoring allows for timely interventions such as electrolyte replacement therapy to prevent cardiac issues.
A: Encouraging the patient to drink fluids and increase food intake is not the priority when dealing with electrolyte imbalances as it may worsen the imbalance.
C: Providing high-protein foods may be beneficial for overall nutrition but does not address the immediate need to correct electrolyte imbalances.
D: Instructing the patient to avoid physical exercise is not directly related to managing electrolyte imbalances and may not address the underlying issue effectively.
