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: A

Rationale: Corrected Rationale: The nurse should instruct the client to use pursed-lip breathing during activities to help improve oxygenation. Pursed-lip breathing can keep the airways open longer, facilitating better oxygen exchange and making it easier to exhale carbon dioxide. Choice B is incorrect as physical activity, within the client's limitations, is beneficial for maintaining overall health. Choice C is incorrect as weight-bearing exercises are important for bone health but not directly related to improving oxygenation in COPD. Choice D is incorrect as using a humidifier while sleeping can help with moisture in the airways but does not directly impact oxygenation in COPD.

Correct Answer: C

Rationale: The correct answer is C. If sterile solution splashes onto the sterile field, it is considered contaminated. Changing gloves in this situation ensures that the sterility of the dressing change is maintained. Choice A is incorrect as non-sterile gloves would introduce contaminants. Choice B is incorrect as layering gloves can increase the risk of contamination. Choice D is incorrect as covering the sterile field with a sterile drape is not the appropriate action to take in response to contamination.

Correct Answer: B

Rationale: The correct answer is to increase fluid intake to 2 liters per day. Adequate fluid intake helps manage hypertension and prevent fluid retention. Limiting sodium intake, avoiding potassium-rich foods, and abstaining from alcohol are important aspects of managing hypertension; however, in this scenario, emphasizing the increase in fluid intake is crucial for the client's understanding and compliance.

Correct Answer: B

Rationale: The correct answer is to discontinue the infusion (Choice B) as the signs described suggest phlebitis, an inflammation of the vein. Increasing the IV flow rate (Choice A) can exacerbate the condition by increasing the irritation. Elevating the limb (Choice C) and applying a cold compress (Choice D) are not the appropriate interventions for phlebitis. Elevation and cold therapy are more suitable for conditions like swelling or inflammation, but in this case, discontinuing the infusion is the priority to prevent further complications.
