Correct Answer: B

Rationale: The correct intervention for a client at risk for pressure injuries is to use a special mattress. Special mattresses help reduce the risk of pressure injuries by redistributing pressure on bony areas, thus preventing tissue damage. Keeping the client in one position (choice A) can actually increase the risk of pressure injuries due to prolonged pressure on specific areas. Turning the client every 4 hours (choice C) is important for preventing pressure injuries, but using a special mattress is a more effective intervention. Providing extra pillows for positioning (choice D) may offer some comfort but does not address the primary intervention of pressure redistribution that a special mattress provides.

Correct Answer: B

Rationale: The correct answer is B: Explain the importance of wearing the eye shield. It is important for the nurse to educate the client on the reasons why wearing the eye shield is crucial post cataract surgery, such as protecting the eye from injury and promoting proper healing. This empowers the client with knowledge and helps them make an informed decision. Choice A is incorrect because the nurse should provide necessary information to ensure the client's safety. Choice C is incorrect as removing the eye shield without proper justification can compromise the client's recovery. Choice D is also incorrect as discussing concerns should come after the client is educated on the importance of the eye shield.

Correct Answer: B

Rationale: Corrected Rationale: Poor nutrition increases the risk of developing pressure injuries as it impairs skin integrity and healing. Frequent repositioning, increased fluid intake, and the use of a special mattress are all important interventions for preventing pressure injuries, rather than risk factors for developing them. Repositioning helps relieve pressure, adequate fluid intake maintains skin hydration, and special mattresses redistribute pressure to prevent injuries.

Correct Answer: B

Rationale: The correct answer is to apply a moisture-retentive dressing. This promotes a moist wound environment, which is crucial for wound healing in clients with diabetes. Encouraging a high-protein diet may support overall health but is not directly related to wound healing. Daily wound irrigation can disrupt the wound healing process by removing necessary growth factors and cells. Applying an ice pack to the wound is contraindicated as it can impair circulation and delay wound healing.

Correct Answer: B

Rationale: The correct instruction for a client with home oxygen therapy is to keep oxygen tubing away from heat sources to prevent fires and other hazards. Option A is incorrect because adjusting the oxygen flow rate without healthcare provider guidance can be dangerous. Option C is incorrect as synthetic fabrics can generate static electricity, which is a fire hazard. Option D is incorrect as oxygen should be left on as prescribed unless advised otherwise.
