Correct Answer: A

Rationale: Administering oxygen at 2 L/min via nasal cannula is the nurse's first action when a client with COPD presents with a respiratory rate of 32 breaths per minute and an oxygen saturation of 86%. Oxygen therapy helps improve oxygen saturation in patients with COPD and respiratory distress. While notifying the healthcare provider is important, immediate intervention to improve oxygenation takes priority. Positioning the client in high Fowler's position can also assist with breathing but is not the initial action in this scenario. Suctioning the airway is not indicated unless there are secretions obstructing the airway, which is not mentioned in the scenario.

Correct Answer: B

Rationale: Shortness of breath in a client with emphysema may indicate respiratory distress. Assessing the client's respiratory rate and effort is the first priority to determine the severity of the distress and guide appropriate interventions. Administering oxygen therapy (Choice A) could be necessary, but assessing the client first is crucial to tailor the intervention. Intubation (Choice C) is an invasive procedure that is not the initial priority. Increasing oxygen flow rate (Choice D) should only be done after a thorough assessment to avoid potential harm.

Correct Answer: C

Rationale: Increased use of a rescue inhaler like albuterol may indicate worsening asthma symptoms. The nurse should first assess the client's respiratory status to determine the severity of the issue and the next steps in care. Option A is not the first action because assessing the client's condition should precede notifying the healthcare provider. Option B, scheduling a pulmonary function test, is not the priority as immediate assessment of the client's respiratory status is crucial. Instructing the client to decrease inhaler use should come after assessing the client's condition to ensure the appropriate intervention.

Correct Answer: D

Rationale: Purulent drainage suggests an infection at the wound site. Reviewing the culture and sensitivity results will guide appropriate antibiotic treatment by identifying the causative organisms and their antibiotic sensitivities. Elevated white blood cells indicate infection but do not specify the organism. Creatinine and hemoglobin values are unrelated to wound infections.

Correct Answer: D

Rationale: The correct response for the nurse in this situation is to discuss the boundaries of the therapeutic relationship with the client. By doing so, the nurse can reinforce professionalism, establish clear boundaries, and prevent ethical conflicts. Option A is incorrect because avoiding the client or unit does not address the issue at hand and may compromise patient care. Option B, while acknowledging the behavior, does not address the underlying reasons and boundaries. Option C, stating hospital policy, is not as therapeutic or client-centered as discussing the therapeutic relationship directly.
