Which of the following indicates that learning has been achieved?

Correct Answer: A

Rationale: Learning is achieved when Matuts exercises and diets (A), showing behavior change, per Bloom's psychomotor domain. Repeating steps (B) is recall, not application. 'I understand' (C) lacks evidence, quiz score (D) tests knowledge, not action. A proves application, making it correct.

Correct Answer: C

Rationale: Hospital safety for a newly admitted client focuses on preventing falls, injuries, and disorientation, especially in an unfamiliar environment. Keeping side rails up at all times (C) is a key measure to prevent falls, particularly during sleep or if the client attempts to get out of bed unassisted, which is a common risk during initial hospitalization. Option A (removing unnecessary furniture) reduces clutter and tripping hazards but is less directly tied to immediate bedside safety. Option B (lights on at all times) may disrupt sleep and is impractical unless needed for observation, not universally ensuring safety. Option D (hiding equipment) may reduce anxiety but does not directly enhance physical safety and could hinder access to necessary tools. Side rails provide a physical barrier, aligning with evidence-based fall prevention protocols in hospitals, making C the most effective safety action for a first-time hospitalized client.

Correct Answer: C

Rationale: Referred pain is felt distant from its source, like shoulder pain with myocardial infarction (MI) (C), per nerve pathway convergence (e.g., diaphragm to shoulder). Stump pain (A) is phantom, surgical site (B) and fracture (D) are local. C exemplifies referred pain's mislocation, making it correct.

Correct Answer: D

Rationale: Death rattle in Mr. Gary results from pooling secretions (A), lost cough reflex (B), and muscle tone loss (C) all (D), per terminal signs. Secretions accumulate, un-cleared due to weak reflexes and muscles, causing rattling. All contribute, making D the correct comprehensive cause.

Correct Answer: C

Rationale: Autopsy isn't done in all deaths (C) untrue; only specific cases (e.g., unclear cause), per protocol. Consent (A), cause (B), and future help (D) are true. C's universality fails, making it the untrue statement.
