To ensure homogenization when diluting powdered medication in a vial, the nurse should:

Correct Answer: B

Rationale: Gentle rolling ensures even mixing without degrading the medication.

Correct Answer: D

Rationale: Schulman and Mekler's moral theory, from the 20th century, measures morality by intent and just acts e.g., Robin Hood's good intent but unjust theft is immoral. Unlike Zderad's humanism, Benner's expertise, or Fowler's faith, they emphasize kindness and fairness, guiding nurses in ethical patient treatment, like ensuring equitable care.

Correct Answer: B

Rationale: Maslow's hierarchy (1940s) crowns self-actualization realizing potential as mental health's essence e.g., a nurse finding purpose in caregiving. Self-awareness (base level), esteem (confidence), and worth (value) build toward it. Nursing promotes this peak, aiding patients in meaningful recovery, aligning with psychological well-being goals.

Correct Answer: C

Rationale: Remittent fever fluctuates above normal (e.g., 38.5-40°C) without returning to baseline common in infections like typhoid. Relapsing (normal intervals), intermittent (spikes to normal), and constant (stable high) differ. Nurses track this pattern e.g., six daily swings for diagnosis and treatment, per fever classification.

Correct Answer: A

Rationale: Hydrocodone depresses respiration e.g., slowing RR in pain management making it correct. Stress, heat, and altitude (low O2) all raise RR e.g., panting in fever. No incorrect factor here, but hydrocodone's known effect aligns with nursing pharmacology for respiratory monitoring.
