The substance that promotes effective bowel elimination is:

Correct Answer: B

Rationale: Fibre promotes bowel elimination by adding bulk and softening stool, easing passage, per dietary guidelines like Canada's Food Guide. Iron aids blood, not digestion directly. Protein builds tissue, not bowel motility. Vitamin A supports vision, not elimination. PSWs manage constipation, and fibre's role in regularity is well-documented, making it the correct substance.

Correct Answer: A

Rationale: Aging starts at birth , as cellular changes begin immediately, per gerontology. Adolescence , 40 , or 60 mark stages, not onset. PSWs see aging across lifespans, making 'Birth' the correct starting point.

Correct Answer: C

Rationale: Comfort measures for pain need tailoring , not uniform like warm blankets or repetition . Not involving family isn't always helpful, but the key selects it, possibly misaligned. Individualizing fits palliative care best, yet 'Do the care yourself' is correct per the key.

Correct Answer: C

Rationale: Dementia features memory loss, short attention span, and impaired judgment, core symptoms per DSM-5 criteria. Stroke may cause sudden deficits, not chronic patterns. Heart attack affects circulation, not cognition directly. Parkinson's involves motor issues, with dementia possible later. PSWs identify these cognitive signs for reporting, making 'Dementia' the correct match for this symptom cluster.

Correct Answer: D

Rationale: Medications come as tablets , syrups , and suppositories , per pharmaceutical forms. Syringe is a delivery tool, not a medication form. PSWs handle these types, making 'Syringe' the correct exception.
