Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In acute shortness of breath with COPD, oxygen therapy is crucial to improve oxygenation levels and alleviate respiratory distress. Oxygen can help reduce the workload on the lungs and heart. Antibiotics (B) are not indicated unless there is a suspected bacterial infection. Monitoring blood glucose (C) is important in diabetes management but not the priority in acute respiratory distress. Administering pain relief (D) may not address the underlying cause of the shortness of breath. Oxygen therapy directly targets the respiratory issue in COPD exacerbation, making it the most effective initial intervention.

Correct Answer: B

Rationale: The correct answer is B: Administer pain relief. The first priority for a client with an open wound is to manage their pain to ensure their comfort and well-being. Pain relief helps the client relax, reduces stress, and promotes healing. Cleaning and dressing the wound, administering anticoagulants, and monitoring blood pressure are important tasks but are secondary to addressing the client's immediate pain and discomfort. Pain relief should be the initial focus to ensure the client's overall care and recovery.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. This is the most appropriate intervention for a wound infection as antibiotics target the underlying bacterial infection causing the wound infection. Antibiotics help to eliminate the infection and prevent it from spreading further. Administering antibiotics is crucial in treating wound infections to promote healing and prevent complications. Choice B (Apply sterile dressing) is incorrect as simply applying a sterile dressing does not address the underlying infection. Choice C (Cleanse and dress the wound) is also incorrect because while wound cleansing is important, it alone may not be sufficient to treat a wound infection. Choice D (Administer analgesics) is incorrect because analgesics only provide pain relief and do not address the infection itself.

Correct Answer: A

Rationale: The correct answer is A: Immobilize the spine. This is the first priority because it helps prevent further injury to the spinal cord. By immobilizing the spine, the nurse ensures that any movement doesn't worsen the existing injury. Placing the client in a supine position (B) can be done after immobilization. Administering analgesics (C) should not be done before assessing the extent of the injury. Assessing the airway (D) is important but should come after immobilizing the spine to prevent any unnecessary movement.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. Antibiotics are crucial in treating pneumonia caused by bacteria. They help to kill the bacteria causing the infection and prevent its spread. Administering fluids (B) is important for hydration but not the most crucial intervention. Monitoring temperature (C) is important but does not treat the root cause. Administering vaccines (D) may prevent certain types of pneumonia but is not the immediate intervention for an existing infection. Administering antibiotics promptly is vital to effectively treat pneumonia and prevent complications.
