H.S. care is performed:

Correct Answer: D

Rationale: H.S. (hora somni) care is bedtime , not morning , afternoon , or dinner . PSWs do this e.g., night prep per routine. Misnaming risks timing errors; bedtime is standard. This term guides PSWs, ensuring restful care, a practical detail in schedules.

Correct Answer: A

Rationale: Subjective e.g., pain is client-felt, not observed , vague , or doctor-only . PSWs note this e.g., reports for plans. Errors risk ignoring input; this fits. This ensures client perspectives shape care, a PSW duty.

Correct Answer: D

Rationale: Implementation is PSW work e.g., bathing unlike assessment , documentation , or planning , which RNs lead. PSWs execute plans. Misnaming risks scope creep; this fits. This focus ensures hands-on care, a PSW core duty.

Correct Answer: A

Rationale: Open-ended questions e.g., 'How do you feel?' stimulate talk, unlike closed , long , or short . PSWs use this e.g., rapport for insight. Closed limits; this fits. This skill draws out needs, a PSW communication tool.

Correct Answer: D

Rationale: Viruses, bacteria, fungi, and protozoa are biological entities studied in microbiology, collectively known as microorganisms . They can cause infections, making them relevant to healthcare workers like PSWs who manage infection risks. Infection control measures are practices (e.g., handwashing) to combat these, not the entities themselves. Foot fungi is too narrow, referring only to fungal infections like athlete's foot, not all listed types. Plaque or tartar relates to dental buildup, often microbial but not encompassing viruses or protozoa. Microorganisms is the broad, scientifically accurate term uniting these pathogens, aligning with foundational knowledge in healthcare training and infection prevention, confirming it as the correct answer.
