Correct Answer: A

Rationale: The correct answer is to maintain the patient's oxygen saturation above 90% when caring for a patient with COPD. In COPD, impaired gas exchange leads to decreased oxygen levels in the blood. By ensuring oxygen saturation remains above 90%, healthcare providers can prevent hypoxia and its complications. Administering bronchodilators as prescribed (Choice B) is an important intervention in managing COPD symptoms, but it is not the primary goal. Improving the patient's nutritional intake (Choice C) and encouraging the patient to limit physical activity (Choice D) are also essential aspects of COPD management, but they are not the primary goal when caring for a patient with this condition.

Correct Answer: A

Rationale: The correct answer is to suction the tracheostomy to maintain a patent airway. After a tracheostomy, the priority intervention is to ensure a clear airway to prevent respiratory distress. Administering pain medication, changing the tracheostomy dressing, and monitoring oxygen saturation are important but are secondary to maintaining a patent airway in a patient who has just undergone a tracheostomy.

Correct Answer: B

Rationale: The correct answer is to recheck the blood pressure before calling for help. When caring for a client with unstable blood pressure, the nurse's priority is to ensure an accurate assessment. Rechecking the blood pressure will confirm the instability and guide further actions. Asking the charge nurse for assistance (Choice A) is important but should come after assessing the situation. Monitoring the client's blood pressure closely (Choice C) is essential, but the immediate action should be to recheck and confirm the current status. Administering antihypertensive medication immediately (Choice D) without a confirmed assessment can be dangerous and is not the initial priority.

Correct Answer: B

Rationale: The priority action when a patient has a fever is to assess the patient's temperature regularly. Monitoring the temperature helps track the effectiveness of interventions and detect any worsening fever. Administering antipyretic medication (Choice A) should be done based on healthcare provider's orders after assessing the patient's condition. While providing cooling measures such as a cool compress (Choice C) can help reduce fever, assessing the temperature takes precedence. Providing blankets for comfort (Choice D) is not the priority when dealing with a fever.

Correct Answer: A

Rationale: The correct answer is to delegate the task to a licensed practical nurse (LPN). LPNs can typically perform suctioning, but it is essential to consider the state's practice guidelines and hospital policy. Option B, delegating to a registered nurse (RN), is not necessary for this task as LPNs are usually competent to handle suctioning. Option C, delegating to a nursing assistant (NA), may not be appropriate as suctioning may require a higher level of training and expertise. Option D, performing the task independently, is not the best choice as delegation is a key aspect of nursing practice to ensure tasks are appropriately assigned based on competency levels.
