The acquisition of new skills and knowledge refers to:

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.

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.

Correct Answer: B

Rationale: Hyperglycemia (high blood sugar) causes increased thirst as the body tries to dilute glucose via urination, per diabetes symptoms. Shakiness and sweating are hypoglycemia signs. Feeling energized contrasts fatigue from high sugar. PSWs monitor this, making 'Increased thirst' the correct symptom.
