What is the primary purpose of the Trendelenburg position?

Correct Answer: D

Rationale: The Trendelenburg position, with the head lower than the feet, improves venous return by using gravity to enhance blood flow back to the heart, often used in shock or low blood pressure scenarios. Facilitating breathing aligns with Fowler's position, not this lungs may compress here. Digestion isn't directly aided; it's circulatory-focused. Social interaction is unrelated it's a clinical posture. Nurses employ this to stabilize hemodynamics, monitoring for respiratory strain, making it a targeted intervention for circulatory support in acute care.

Correct Answer: C

Rationale: Cleansing the perineal area from front to back after toileting prevents UTIs in female patients by keeping fecal bacteria away from the urethra, a short pathway prone to infection. Holding urine fosters bacterial growth, increasing risk. Back-to-front wiping introduces pathogens, the opposite of prevention. Limiting fluids concentrates urine, encouraging infection, not deterring it hydration flushes bacteria. Nurses teach and reinforce this technique, especially in dependent care, to minimize UTI incidence, a common yet avoidable issue.

Correct Answer: A

Rationale: A warm compress provides pain relief for muscle stiffness by increasing blood flow, relaxing tense fibers, and easing discomfort from spasms or immobility. Sweating might occur but isn't the goal relief is. Lowering temperature requires cold, not warmth heat does the opposite. Promoting contraction contradicts relaxation; it loosens, not tightens. Nurses apply it to soothe and improve flexibility, a targeted comfort measure leveraging heat's therapeutic effects on musculoskeletal pain.

Correct Answer: D

Rationale: Providing assistance with nail care as needed ensures proper hygiene for a mobility-impaired patient by trimming or cleaning nails to prevent overgrowth or infection, tailored to their ability. Avoiding care risks ingrown nails or dirt buildup, inviting infection, not preventing it. Yearly hygiene is neglect monthly or as needed is standard. Doing it fully saves time but may not empower support balances help with autonomy. Nurses use clippers or files, aiding grooming safely, a detail enhancing comfort and health.

Correct Answer: C

Rationale: Speaking really loud does not demonstrate professionalism it's disruptive, lacks sensitivity, and may distress clients, unlike a positive attitude (uplifting care), advocacy (supporting needs), and discretion (maintaining boundaries). Professionalism requires calm, respectful communication tailored to client needs, not volume for its own sake. Health care aides must adapt e.g., raising volume only for hearing-impaired clients with clear intent ensuring interactions foster trust and dignity. Loudness without purpose signals impatience or poor judgment, undermining the aide's role as a composed, client-focused caregiver in diverse settings.
