Which of the following would be the best strategy for the nurse to use when teaching insulin injection techniques to a newly diagnosed client with diabetes?

Correct Answer: D

Rationale: Return demonstration confirms skill mastery and corrects errors.

Correct Answer: B

Rationale: Lukewarm water is ideal for bathing as it cleans effectively without risking burns or chilling the patient, especially those with reduced sensation or circulation, like the elderly. Extremely hot water can scald, causing injury, while ice-cold water may shock the system or cause discomfort, particularly in frail patients. Patient preference matters, but safety trumps comfort nurses must ensure the temperature is within a safe range (typically 38-40°C). Lukewarm water balances hygiene, comfort, and protection, preventing skin damage and maintaining dignity during this intimate task, a key aspect of basic care.

Correct Answer: D

Rationale: Passive range-of-motion exercises, where the nurse moves the patient's limbs, maintain joint mobility and prevent contractures in bedridden patients unable to move themselves. This preserves flexibility and circulation, staving off stiffness and deformity from disuse. Independence isn't the immediate goal assistance is required. Assessing strength might occur incidentally, but it's not the purpose; active exercises test that. Exercise for staff is a byproduct, not the intent it's patient-focused. Nurses perform this to counteract immobility's effects, ensuring long-term joint health and comfort in dependent care scenarios.

Correct Answer: C

Rationale: A cooling blanket reduces a febrile patient's body temperature by transferring heat away from the skin, countering fever's effects and preventing complications like seizures. Inducing shivering raises temperature opposite of the goal and wastes energy. Providing warmth worsens fever, delaying recovery. Sweating might occur but isn't the aim; toxin elimination is a misconception cooling targets thermoregulation. Nurses use this to safely lower fever, monitoring closely to avoid overcooling, ensuring comfort and stability in hyperthermic states.

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.
