If a person is responsible for their actions and bound to give an explanation, they are considered:

Correct Answer: B

Rationale: Accountable means explaining actions e.g., errors unlike employed , regulated , or licensed . PSWs own this e.g., reporting for ethics. Misnaming risks duty; this fits. This ensures trust, a PSW core in care.

Correct Answer: C

Rationale: In healthcare, a 'clean area' has a specific meaning tied to infection control. It must be free from pathogens , such as bacteria or viruses, to prevent disease spread, achieved through cleaning and disinfection protocols. Clearing clutter improves safety but doesn't guarantee pathogen absence. Contaminated with microorganisms defines a dirty area, the opposite of clean. No safety hazards addresses physical risks, not microbial cleanliness, which is the primary concern in care settings. 'Free from pathogens' aligns with medical asepsis standards, ensuring a safe environment for clients and staff, as emphasized in PSW training and facility policies, making it the precise and correct definition.

Correct Answer: A

Rationale: Epithelial tissue covers body surfaces, including cutaneous (skin), serous (organ linings), and mucous (tract linings) cells, protecting and secreting as needed. Muscle tissue enables movement, not covering. Nerve tissue transmits signals, not a surface layer. Connective tissue supports and binds, like cartilage, but doesn't line surfaces. Histology classifies epithelial tissue for its protective and lining roles, critical for PSWs in wound care or hygiene, making 'Epithelial' the correct answer over other tissue types with distinct functions.

Correct Answer: C

Rationale: Tangled hair requires gentle care to avoid pain or damage. Wetting with alcohol dries hair, worsening tangles, and isn't standard. Cutting tangles is a last resort, risking uneven results or distress. Calling the nurse escalates unnecessarily for a routine task. Combing one small section at a time is the best first step starting at ends, working up minimizing breakage and discomfort. PSW grooming protocols prioritize patience and client comfort, making this methodical approach the correct initial action.

Correct Answer: C

Rationale: Obese residents face higher skin breakdown risk in skin folds , where moisture, heat, and friction accumulate, fostering irritation or infection (e.g., intertrigo). Knees and calves are less prone unless pressure is constant. The abdomen may be affected but isn't as common as folds (e.g., under breasts, groin). PSW training highlights monitoring these hidden areas, supported by clinical observations of obesity-related skin issues, making 'Skin folds' the correct and most likely location.
