Your resident is anemic and is often pale and tired due to decreased amounts of which mineral?

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: B

Rationale: Infancy is birth to one year, a developmental stage marked by rapid growth, per pediatric standards. Prenatal (Choice A, C) is pre-birth. Birth to two includes toddlerhood. PSWs caring for families use this timeframe, making 'Time from birth to one year of age' the correct definition.

Correct Answer: C

Rationale: Aging affects the nervous system: dulled senses , shrinking brain cells and reduced blood flow , and altered sleep are true, per gerontology. Less cough strength is respiratory/muscular, not nervous system directly. PSWs note these changes, but the answer key marks 'C' as false, possibly a typo, though 'D' fits exclusion better. Per key, 'Sleep patterns may change with age' is correct.

Correct Answer: D

Rationale: Preventing dehydration in dying clients involves accessible drinks and regular sips , per palliative care. Coffee, tea, and alcohol dehydrate. 'Both a and b' combines effective methods, making it the correct and practical approach.

Correct Answer: C

Rationale: Alzheimer's cause isn't fully understood , with genetics and environment implicated, per research. It's not just over 65 , not normal aging , and lacks recovery . PSWs manage its progression, making 'The cause is not fully understood' the correct and current truth.
