What is the primary purpose of using a water-based moisturizer on a patient's skin?

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: 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.

Correct Answer: D

Rationale: Erasing or whiting out errors is incorrect because it compromises the integrity of medical records, which must remain accurate and tamper-proof for legal and care continuity purposes. Using ink ensures permanence, legible writing aids clarity, and including time, date, and initials tracks accountability standard practices for PSWs. Altering records by erasure risks miscommunication or errors in client care, like missing a medication dose, and could violate regulations. PSWs must instead strike through mistakes with a single line, initial, and correct them visibly, preserving transparency. This distinction is critical in training, as accurate documentation supports client safety, team coordination, and legal defensibility, unlike erasable methods that obscure the care history.

Correct Answer: A

Rationale: A message goes from speaker to receiver in communication, not receiver to speaker , speaker to speaker , or without feedback . PSWs use this e.g., explaining care to a client expecting feedback like a nod. Misunderstanding this risks one-way communication, missing client input. Effective exchange ensures needs are heard and met, like adjusting care based on responses, a daily PSW skill enhancing rapport and accuracy in client interactions.
