Correct Answer: D

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.

Correct Answer: A

Rationale: Resonance refers to the quality of sound produced by vibrations that are reinforced by other vibrations of the same frequency. In the context of the human body, resonance is often associated with sounds produced by air-filled structures like the lungs, vocal cords, and resonating cavities. Therefore, the best description of resonance from the given options is 'Sounds created by air-filled lungs.' This choice aligns with the concept of resonance as it relates to sound production in the human body.

Correct Answer: A

Rationale: During a client's first hospitalization, it is essential to keep unnecessary furniture out of the way to prevent obstacles and ensure a safe environment. This action helps reduce the risk of accidents or falls, promoting the client's safety and well-being. Keeping the lights on at all times may not be necessary and can disrupt the client's rest. Keeping side rails up at all times can restrict the client's movement and independence unnecessarily. Keeping all equipment out of view may hinder the healthcare team's ability to monitor and access necessary tools for providing care.

Correct Answer: C

Rationale: The appropriate route of administration for insulin is subcutaneous. Subcutaneous injections are commonly used for insulin administration due to the slower absorption rate compared to intramuscular or intravenous routes, allowing for better control of blood glucose levels.

Correct Answer: B

Rationale: Buccal medication is administered by placing it between the client's cheeks and gums. This route allows for the medication to be absorbed through the mucous membranes in the mouth, providing a rapid onset of action compared to oral ingestion. Placing the medication under the tongue (sublingual) allows for absorption through the sublingual mucosa, not the buccal mucosa. Placing medication on the skin or the conjunctiva is not appropriate for buccal administration.
