What preoperative lab test is essential for a patient with anorexia?

• A. Blood glucose levels
• B. Electrolytes
• C. Liver enzymes
• D. Complete blood count (CBC)

Answer: (B)

Electrolyte levels are crucial to assess in a patient with anorexia prior to surgery. Anorexia can lead to significant nutritional deficiencies and imbalances in the body's electrolyte levels, such as potassium, sodium, and chloride. These imbalances can result in serious complications, including cardiac arrhythmias and metabolic disturbances, which may impact the patient's ability to tolerate anesthesia and surgery. Evaluating electrolytes helps identify any abnormalities that need to be addressed before proceeding with surgical interventions. This proactive approach can significantly improve patient safety and outcomes during the perioperative period. While other tests like blood glucose, liver enzymes, and complete blood count can provide useful information regarding the patient's overall health, they do not specifically target the immediate risks associated with the electrolyte imbalances that are often seen in patients with anorexia. Therefore, focusing on electrolyte levels is key in this context to identify critical preoperative conditions.
