Which site would be safer and less expensive for temperature measurement of a human?

• A. Skin
• B. Axilla
• C. Oral Cavity
• D. Rectum

Answer: (A)

Measuring temperature at the skin surface is the safest and most economical choice because it avoids any insertion into the body and uses minimal equipment. There’s no risk of injury to internal tissues and little risk of infection, which makes it safer for all ages and keeps costs down since you can use a simple thermometer or a basic noncontact infrared device with few or no disposables. Of course, skin temperature can be influenced by ambient temperature and peripheral blood flow, so it may not reflect the true core body temperature as accurately as deeper sites. Still, when safety and cost are the priorities, the skin is the best option. The rectal site is invasive and carries higher risk of injury and infection and requires more careful handling; the oral cavity can provoke gagging or choking and needs cooperation and clean technique; the axilla is noninvasive but can be less reliable due to sweating and surrounding temperature.
