When the physician telephones to order a therapy such as a medication for the client of a student nurse, who is the best person to take this telephone order?

Correct Answer: A

Rationale: Hospital policy dictates who takes telephone orders, ensuring legal and safety compliance, typically a licensed nurse, not a student or instructor alone. This standard protects clients from errors by untrained personnel, aligning with nursing scope and institutional rules for accurate order execution.

Correct Answer: D

Rationale: NANDA defines acute pain as lasting up to 6 months, beyond which it's chronic. Nurses use this timeframe for diagnosis accuracy.

Correct Answer: C

Rationale: Contractures permanent muscle and tendon shortening indicate a musculoskeletal complication of immobility, restricting joint movement due to prolonged stillness. High muscle tone might suggest other conditions, while active motion and strong joints reflect health, not issues. Nurses assess for this to initiate stretching or therapy, countering the stiffening that immobility causes, ensuring musculoskeletal function is preserved as much as possible in affected patients.

Correct Answer: C

Rationale: Improving oxygen delivery to tissues (C) is the primary indication for oxygen therapy in pneumonia with distress and low SpO2, correcting hypoxia from impaired gas exchange. Lung expansion (A) is secondary. Antimicrobial therapy (B) treats infection, not oxygenation. Bacterial resistance (D) is unrelated. Enhanced oxygen delivery supports vital organs, per infectious disease care principles, critical in acute respiratory compromise.

Correct Answer: C

Rationale: Avoiding electric heating devices (C) is critical in COPD oxygen therapy teaching, as oxygen accelerates combustion, posing a fire risk. Fire extinguisher (A) is supplementary. Loose tubing (B) risks disruption. Concentrator use (D) depends on need. Safety education, per home care standards, prioritizes fire prevention.
