An autoclave is used to sterilize hospital supplies because:

Correct Answer: D

Rationale: Pressurized steam enhances penetration, ensuring thorough sterilization.

Correct Answer: C

Rationale: Lawrence Kohlberg's moral development theory, from the 1950s, hinges on mutual trust e.g., a child learns fairness through reciprocal relationships. Freud's psychoanalysis, Erikson's psychosocial stages, and Peters' principle-based morality differ. Kohlberg's stages premoral (reward/punishment), conventional (social norms), post-conventional (personal ethics) explain moral growth, influencing nursing ethics education on trust-based patient interactions.

Correct Answer: D

Rationale: Maslow's theory (1940s) allows need priorities to shift e.g., delaying hunger for safety in crisis. Needs interrelate (safety affects esteem), aren't rigid, and can be deferred. Nurses adapt care e.g., addressing fear before nutrition in trauma reflecting this alterability, key to responsive patient management.

Correct Answer: A

Rationale: Body temperature peaks late day (8 PM-midnight) due to circadian rhythms e.g., higher metabolism. Lowest is early morning (not noon), thyroxin raises temp (not lowers), and elderly risk hypothermia (not hyperthermia) from poor regulation. Nurses monitor this pattern for fever assessment, per physiological norms.

Correct Answer: A

Rationale: The medulla oblongata's respiratory center sets breathing rhythm and depth e.g., 12-20 breaths/min via dorsal and ventral groups. Pons refines, carotid/aortic bodies adjust via chemo input. Nurses assess this e.g., in COPD for foundational respiratory function, per neurophysiology.
