How can a nurse promote safety during ambulation with a patient using a walker?

Correct Answer: D

Rationale: Ensuring the patient uses the walker as a weight-bearing aid promotes safety by providing stable support, distributing weight to reduce fall risk during ambulation. Pushing the walker from behind destabilizes it, removing patient control. Lifting it with each step negates its purpose continuous contact is key. Leaning forward risks tipping or losing balance. Nurses guide patients to grip firmly and step within the walker's frame, enhancing stability and confidence, a practical approach to safe mobility assistance.

Correct Answer: D

Rationale: A water-based moisturizer maintains skin hydration and prevents dryness by locking in moisture, protecting against cracking or irritation, especially in dry or elderly skin. Cooling might occur briefly but isn't the aim temperature regulation uses other methods. Removing oil isn't its role; it adds, not strips, hydration. Cleansing requires soap, not moisturizer it's a follow-up step. Nurses apply this to vulnerable areas like elbows or heels, supporting skin integrity and comfort, a simple yet effective care measure.

Correct Answer: B

Rationale: Elevating the head of the bed and providing breathing exercises promotes comfort in dyspnea by opening airways, easing lung effort, and teaching control over breath, reducing panic and strain. Rapid, shallow breathing worsens oxygen deficit and fatigue. Sedatives might calm but suppress respiration, risking decline. Supine positioning compresses lungs, intensifying distress. Nurses use Fowler's position and pursed-lip techniques, enhancing airflow and comfort, a dual approach vital for respiratory relief.

Correct Answer: C

Rationale: Supporting the lower back with a cushion promotes comfort and pain relief by aligning the spine, reducing strain on muscles and discs in back pain patients. Lying flat often worsens lumbar stress elevation or support helps. Direct heat pad application risks burns; a barrier is safer, and heat isn't the only fix. Limiting movement excessively stiffens, not relieves gentle activity aids. Nurses position cushions strategically, easing pressure points, a simple adjustment for sustained back comfort.

Correct Answer: D

Rationale: A funeral home is not a typical workplace for a health care aide, as their role centers on living clients providing personal care in group homes (e.g., disabled residents), acute care (e.g., hospital support), and long-term care (e.g., nursing homes). Funeral homes involve post-mortem tasks like embalming, outside an aide's scope of supporting daily living or recovery. Aides assist with ADLs and observation, not deceased care, making this an outlier. Knowing work settings ensures aides pursue relevant roles, aligning skills with client needs, not misapplying them in unrelated fields.
