Vital Signs Assessment Chapter 7 Questions

Question 1 of 5

The patient is lying in bed under a ceiling fan. Which technique is the nurse using when the fan produces heat loss?

Correct Answer: C

Rationale: A ceiling fan moves air over the patient, causing heat loss via convection , where warm air around the body is replaced by cooler moving air. Radiation involves heat emission without contact, not fan-driven. Conduction requires direct contact (e.g., cold pack), not air movement. Evaporation involves moisture loss, not primarily fan-related here. Choice C is correct because convection matches the mechanism of air circulation enhancing heat dissipation, a principle nurses apply in thermoregulation strategies to cool patients effectively in clinical settings.
