Nutrients used primarily to build and repair body tissues are:

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: 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.

Correct Answer: A

Rationale: Restlessness and wandering at night in dementia clients is sundowning , a late-day agitation pattern, per neurological studies. Delirium is acute confusion, not time-specific. Stroke or heart attack are physical events, not behavioral. PSWs manage sundowning with routine and calm, recognizing its prevalence in Alzheimer's, making 'Sundowning' the correct term for this behavior.

Correct Answer: A

Rationale: Q.i.d. (quater in die) means four times a day , a standard abbreviation in prescriptions, per pharmacology. Every other day , once , or twice are q.o.d., q.d., or b.i.d. PSWs read labels accurately, making 'Four times a day' the correct frequency.
