Rationale: The correct answer is Inspection (Choice A). Inspection is a technique that involves observing the patient using the sense of sight. During inspection, a healthcare provider visually examines the patient for any abnormalities, changes, or specific signs that may help in diagnosing a condition. Palpation (Choice B) involves using the sense of touch to feel for abnormalities, Percussion (Choice C) involves tapping the body to produce sounds that can help identify the underlying structures, and Auscultation (Choice D) involves listening to sounds produced by the body, typically using a stethoscope. Therefore, in this context, the technique that specifically involves the sense of sight is Inspection.

Rationale: In cases where the oral route is not recommended due to oral surgery or altered consciousness, the rectal method is preferred for the most accurate body temperature reading. This method is particularly useful when the skin is flushed and warm, as it provides a reliable reflection of core body temperature despite external factors affecting the skin temperature. Axillary temperature may not be as accurate, and arterial line temperature monitoring is invasive and not typically used for routine temperature assessment.
