In suspected heat-related illness, which management step involves potential IV access and fluids?

• A. Oral hydration with water only
• B. Only oxygen therapy
• C. Withhold fluids until treatment
• D. Intravenous fluids administration

Answer: (D)

IV fluids administration is the step that involves IV access because heat-related illness often causes significant fluid losses from sweating, which can drop circulating blood volume and hinder perfusion and cooling. Establishing IV access allows rapid delivery of isotonic fluids to restore intravascular volume, correct electrolytes, and support organ function as you begin cooling measures. Oral hydration can be useful if the patient is alert and able to drink, but it’s slower and not reliable in acutely ill or vomiting patients. Oxygen therapy may help with breathing but doesn’t address the fluid deficit. Withholding fluids would worsen dehydration and delay recovery, especially in more severe cases where rapid rehydration is crucial.
