In a patient with profuse vomiting and diarrhea, what is the nurse most concerned about?

• A. Fluid and electrolyte imbalance
• B. Airway obstruction
• C. Skin breakdown
• D. Weight gain

Answer: (A)

Profuse vomiting and diarrhea strip the body of fluids and essential electrolytes, leading to dehydration and electrolyte disturbances. This directly threatens circulating volume and tissue perfusion, so fluid and electrolyte imbalance is the nurse’s primary concern. Look for signs like rapid pulse, low blood pressure, dry mucous membranes, decreased urine output, and confusion, which reflect hypovolemia and electrolyte issues. Airway concerns can arise in other scenarios, but the most immediate risk here is the imbalance of fluids and electrolytes; weight changes and skin breakdown are less acute in this context.
