A nurse is assisting with teaching a newly licensed nurse about the loss of body heat. The nurse should include that heat loss that occurs when sweat dries on the skin is caused by which of the following mechanisms?
Convection
Evaporation
Conduction
Radiation
The Correct Answer is B
A: Convection involves the movement of air or liquid around the body, which then carries heat away but does not involve phase change like evaporation.
B: Evaporation is the process where liquid (sweat) turns into vapor, removing heat from the surface it evaporates from, which is the primary cooling mechanism in sweating.
C: Conduction involves direct transfer of heat through contact with cooler objects, not relevant to the drying of sweat.
D: Radiation refers to heat transfer through electromagnetic waves and does not require the presence of an intervening medium, unlike the evaporation of sweat.

Correct Answer is B
Explanation
A: Anisocoria refers to a condition where the pupils are of unequal sizes, which is not related to focusing ability.
B: Accommodation response involves the ability of the eye to change focus from distant to near objects, demonstrating the flexibility of the lens which is exactly what the instruction aims to test.
C: Direct pupil response relates to pupil constriction in response to light, not changes in focal distance.
D: Consensual reflex also refers to the reaction of both pupils to light and would not be assessed through changes in focal distance.
Correct Answer is A
Explanation
A: This helps reduce body temperature by increasing heat loss through evaporation and radiation. Removing layers allows the body’s natural cooling mechanisms to function more effectively.
B: This would be inappropriate because adequate hydration is crucial for a febrile patient to help regulate body temperature and prevent dehydration.
C: This would be counterproductive as it would add heat to the body instead of helping to lower the body temperature.
D: Increasing the room temperature would worsen the situation by making the environment warmer, which would hinder the body's ability to cool down naturally.
