ATI Pharmacology Quiz 3 e25 | Nurselytic

Correct Answer: A

Rationale: The correct answer is A. The 18-month-old with watery stools for 3 days is at the greatest risk for developing an acid-base imbalance or electrolyte disorder due to potential dehydration and loss of electrolytes through diarrhea. Watery stools can lead to fluid and electrolyte imbalances, especially in young children who have higher fluid requirements and are more susceptible to dehydration.

Choices B, C, and D do not present immediate risks for developing acid-base imbalances or electrolyte disorders. A client with a gastrostomy tube may have specialized nutritional needs, but it does not inherently indicate an increased risk of these imbalances. Constipation in a 70-year-old and a short history of nausea and vomiting in a 27-year-old are not typically associated with significant fluid or electrolyte disturbances.
