The primary health risk of a mild skin injury is:

Correct Answer: B

Rationale: A mild skin injury, like a scratch, breaches the protective barrier, making infection the primary risk as bacteria enter, potentially worsening if untreated. Gangrene is a severe outcome, not immediate. Fluid loss applies to burns, not mild injuries. Nerve damage is unlikely unless deeper. PSWs prioritize cleaning wounds to prevent infection, per basic first aid and infection control principles, making it the correct and most immediate concern.

Correct Answer: A

Rationale: Proteins, vitamins, and minerals build and repair tissues proteins form structures, vitamins aid processes, minerals strengthen bones per nutrition science. Carbs and fats provide energy, not repair. Fats and water support other functions. Iron and fats are too narrow. PSWs ensure these nutrients for healing, making 'Proteins, vitamins, and minerals' the correct tissue-building trio.

Correct Answer: B

Rationale: Handwashing before procedures prevents infection, a universal precaution in PSW practice per CDC or Health Canada guidelines. Reporting isn't always required first. Consent is assumed in care plans unless refused. Completing flow sheets follows the task. Hygiene is foundational, making 'Wash his/her hands' the correct initial step.

Correct Answer: B

Rationale: Gerontology studies aging, its physical and social impacts, per academic definitions. Pediatrics is children. Genealogy is family history. Gynecology is women's health. PSWs work with aging clients, making 'Gerontology' the correct term.

Correct Answer: C

Rationale: The coroner confirms identity and cause , but also investigates responsibility in suspicious deaths, per legal roles. 'Both a and b' is partial. The key picks 'C', possibly a typo, but coroners probe causation, making 'Figure out who caused the death' correct per context.
