Which statement best describes the purpose of a nasogastric (NG) tube?

Correct Answer: C

Rationale: A nasogastric (NG) tube delivers nutrients and medication directly to the stomach, bypassing the mouth for patients unable to eat or swallow, like those post-surgery or unconscious. Oxygen delivery uses nasal cannulas or masks, not NG tubes. Blood pressure measurement involves cuffs, not gastric access. Heart rate monitoring uses ECGs or pulse checks unrelated to NG function. Nurses insert and manage NG tubes to ensure nutritional support and drug administration, verifying placement to avoid complications, a vital tool in acute care settings.

Correct Answer: D

Rationale: Creating a quiet and calm environment at night promotes comfort and sleep by minimizing noise and stress, aligning with the body's circadian rhythm for restful recovery. Constant light disrupts sleep cycles, causing agitation. Daytime napping may fragment nighttime rest, not enhance it. Limiting communication isolates, not comforts gentle interaction can soothe. Nurses dim lights, reduce chatter, and manage interruptions, crafting a hospital setting conducive to healing sleep, vital for physical and emotional well-being.

Correct Answer: D

Rationale: Soft restraints promote comfort and prevent skin irritation by using padded materials to limit movement safely, protecting patients at risk of self-harm or falls without causing abrasions. Punishment is unethical restraints are protective, not punitive. Restricting movement is the mechanism, not the purpose; comfort is the goal within that. Encouraging movement contradicts their use they're for safety. Nurses apply them snugly but gently, monitoring skin and adjusting, ensuring minimal discomfort while meeting safety needs, per care standards.

Correct Answer: C

Rationale: Providing assistive devices like glasses and magnifiers enhances comfort and safety for a visually impaired patient by improving sight, reducing strain, and aiding navigation. Lights off obscure hazards, risking falls soft lighting helps. Frequent rearrangement disorients, increasing danger. Avoiding communication isolates, not comforts verbal cues assist. Nurses ensure devices fit and guide verbally, boosting independence and security, a tailored approach to sensory support in daily care.

Correct Answer: B

Rationale: Providing small bites and ample time for eating accommodates a Parkinson's patient's tremors and slow swallowing, reducing choking risk and ensuring comfort. Quick eating heightens danger slowness is safer. Feeding tubes are invasive and unnecessary unless swallowing fails completely. Limiting fluids risks dehydration, not aspiration prevention sips are manageable. Nurses offer bite-sized portions, wait patiently, and monitor, balancing nutrition with safety, a tailored approach to motor and swallow challenges in this condition.
