The basic functional unit of the body is the:

Correct Answer: A

Rationale: The cell is the basic functional unit of the body , as it's the smallest structure capable of life processes like metabolism and reproduction. Tissues are groups of cells with a shared function, organs are made of tissues, and organ systems combine organs each level builds on cells. Anatomy and physiology texts, like those used in PSW training, establish cells as the foundation of all bodily functions, from muscle contraction to nerve signaling. This hierarchical understanding underscores why cells are fundamental, performing essential tasks independently or collectively, making 'Cell' the scientifically accurate and correct answer.

Correct Answer: A

Rationale: PSWs assist with hygiene but have scope limits. Cutting a diabetic's toenails is risky due to poor circulation and infection potential, reserved for podiatrists. Washing hair , back massages , and perineal care are routine PSW tasks, promoting cleanliness and comfort. Diabetic foot care requires specialized training beyond PSW authority, per healthcare regulations, making 'Cut a diabetic person's toenails' the correct exception to their duties.

Correct Answer: D

Rationale: Failure to self-provide due to inattention or dissipation fits self-neglect , where one neglects personal needs, like hygiene. Self-care deficits describe inability to perform care tasks, often linked to neglect. Difficulty with ADLs reflects functional challenges contributing to neglect. 'All of the above' encompasses these overlapping concepts, as PSW training recognizes them as interrelated in elderly or impaired clients, making it the correct, holistic answer.

Correct Answer: D

Rationale: Anemia, often iron-deficiency, causes paleness and fatigue due to low hemoglobin, reliant on iron . Water affects hydration, not blood directly. Sodium balances fluids, not red cells. Calcium strengthens bones, not oxygen transport. PSWs recognize iron's role in energy, per nutritional care, and its deficiency aligns with anemia symptoms, making 'Iron' the correct mineral.

Correct Answer: A

Rationale: Learning is acquiring new skills and knowledge, a process PSWs support in clients or themselves, per educational theory. Motivation drives learning, not the act. Development is broader growth, not just skill gain. Prevention avoids issues, not acquisition. Basic terminology in care training defines 'Learning' as this process, making it the correct and precise answer.
