Patient Care Test Questions Questions
Question 1 of 5
Which of the following is the control centre of the cell?
Correct Answer: D
Rationale: The nucleus is the cell's control center, housing DNA and regulating gene expression, protein synthesis, and cell division key functions for cellular activity. The cell membrane controls entry and exit but doesn't direct internal processes. The axon is a nerve cell feature, not universal to all cells. Cytoplasm supports organelles but lacks control authority. Biology fundamentals, as taught in healthcare courses, emphasize the nucleus's role in orchestrating cellular life, akin to a command hub, making it the correct answer over structural or supportive components.
Question 2 of 5
All of the following are functions of the skin except:
Correct Answer: A
Rationale: The skin's functions include protection against pathogens, waste elimination via sweat, and temperature regulation through sweating or shivering. Movement is a muscle function, not skin's role, which is static as a barrier and regulator. PSWs learn these in skin care, per anatomy texts like Tortora's, where skin's integumentary roles exclude motility. This distinction makes 'Movement' the correct exception among the options.
Question 3 of 5
When reporting abuse include:
Correct Answer: D
Rationale: Reporting abuse requires detailed, factual documentation for investigation and protection. What you heard, saw, and observed provides evidence. The name of the abused identifies the victim. When it was discovered establishes a timeline. 'All of the above' ensures a complete report, aligning with PSW legal and ethical duties under abuse protocols (e.g., Ontario's Long-Term Care Homes Act), making it the correct and thorough requirement.
Question 4 of 5
The process of ingestion, digestion, absorption, and the use of food by the body is called:
Correct Answer: C
Rationale: Nutrition encompasses ingestion, digestion, absorption, and food use, defining how the body processes nutrients, per health science. Metabolism is energy conversion, a subset. Diet is food consumed, not the process. Fluid intake is hydration, not full nutrition. PSWs support nutrition, and this term holistically covers the described stages, making it the correct and complete answer.
Question 5 of 5
Which one of the following terms refers to no control of bladder and bowels?
Correct Answer: A
Rationale: Incontinent means no control over bladder or bowels, a condition PSWs manage with hygiene care. Inconsistent implies irregularity, not loss. Incompetence is ability-based, not physical. Incomplete suggests partiality, not control absence. Clinical terms in PSW practice define 'Incontinent' this way, making it the correct and specific term.
