Correct Answer: A

Rationale: Step 1: Stop the transfusion - Febrile reaction can indicate a transfusion reaction, so stopping the transfusion is crucial. Step 2: Administer antipyretics - To reduce fever and prevent further complications. Step 3: Assess for other signs of transfusion reaction - Such as chills, rash, or hypotension. Summary: Option A is correct as it addresses the immediate need to stop the transfusion and manage the fever. Options B, C, and D do not prioritize stopping the transfusion, which is crucial in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Ensure the lens is centered on the cornea. This is important because removing a hard contact lens that is not centered can cause damage to the cornea or surrounding structures. By ensuring the lens is properly positioned on the cornea before attempting removal, the risk of injury is minimized. Explanation of other choices: A: Gently irrigating the eye with solution is not the correct procedure for removing hard contact lenses as it does not address the specific task of lens removal. B: Grasping the lens with a gentle pinching motion can be harmful if the lens is not centered, leading to potential damage to the eye. D: Using sterile gloves before attempting removal is important for hygiene but does not directly affect the safe removal of hard contact lenses from an unresponsive client.

Correct Answer: B

Rationale: The correct answer is B: Place in a safe environment. This is the first priority to ensure the safety of the confused post-operative client. Placing the client in a safe environment prevents harm from falls or accidents. Reorienting the client (choice A) can come after ensuring safety. Administering pain relief (choices C and D) should be done based on assessment but is not the first priority when the client is confused.

Correct Answer: B

Rationale: Correct Answer: B - Administer oxygen Rationale: 1. Oxygen therapy is crucial in managing COPD exacerbation to improve oxygen saturation levels. 2. Adequate oxygenation is essential to prevent further respiratory distress and potential complications. 3. Oxygen therapy helps alleviate symptoms like shortness of breath and fatigue, improving overall comfort. 4. Monitoring oxygen saturation levels guides the effectiveness of treatment and ensures appropriate oxygen delivery. Summary: - Administering corticosteroids (A) may help reduce inflammation in COPD exacerbation but does not address the immediate need for oxygen. - Monitoring respiratory rate (C) is important but prioritizing oxygen administration is more critical for immediate respiratory support. - Administering diuretics (D) may be indicated in certain cases of COPD exacerbation with fluid retention but is not the priority over oxygen therapy.

Correct Answer: A

Rationale: The correct answer is A: Monitor urine output. This is the most important action because it helps assess the client's fluid status and kidney function. Monitoring urine output can indicate if the client's body is effectively eliminating excess fluid. Elevating the head of the bed (B) helps with respiratory function but is not the priority in fluid overload. Administering diuretics (C) may be necessary but should be based on urine output monitoring. Encouraging deep breathing (D) is important for respiratory function but not directly related to managing fluid overload.
