Blood vessels that carry blood away from the heart are:

Correct Answer: B

Rationale: Arteries carry blood away from the heart, delivering oxygen-rich blood (except pulmonary arteries) to tissues, driven by heart pressure. Veins return blood to the heart, often oxygen-poor. Capillaries connect arteries and veins for exchange, not directional flow. Valves regulate flow within vessels, not vessels themselves. Circulatory anatomy, essential for PSWs taking vital signs, defines arteries by their outward role, confirmed by texts like Marieb's, making 'Arteries' the correct vessel type.

Correct Answer: D

Rationale: Neglect is failing to meet a client's needs, which can manifest as emotional/psychological abuse , like ignoring distress, or physical neglect , like not changing soiled linens. Sexual abuse involves specific acts, not neglect's omission. 'Both a and b' captures neglect's broad scope, as it can harm emotionally (isolation) or physically (hygiene neglect), per abuse definitions in PSW training. This inclusivity reflects real-world scenarios, making it the correct and comprehensive answer.

Correct Answer: B

Rationale: Dehydration, a fluid deficit, reduces urine production as the body conserves water, making decreased urinary output a key sign. Moist skin indicates hydration, not loss. Increased urinary output suggests excess fluid, opposite of dehydration. Increased energy contradicts fatigue from fluid lack. PSWs monitor these signs, and clinical standards list reduced urine as primary, alongside dry mouth or thirst, making it the correct symptom.

Correct Answer: C

Rationale: Temperature readings are affected by recent activity. Smoking raises oral temperature briefly, so waiting 15 minutes ensures accuracy, per PSW vital signs training. Listening to a CD or foot care don't impact temperature. Bedtime is unrelated. Waiting post-smoking aligns with clinical standards for reliable readings, making it the correct reason.

Correct Answer: D

Rationale: Rehabilitation restores function, helping clients relearn skills (e.g., walking) post-injury, per restorative care goals. Stress reduction is secondary. Functioning as an adult is vague. Rest isn't rehab's focus. PSWs support this relearning, making 'Relearn how to do things for himself/herself' the correct purpose.
