Nursing Elites

1. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

2. A client with a peripherally inserted central catheter (PICC) line has a fever. What client assessment is most important for the nurse to perform?

• A. Inspect the PICC insertion site for signs of infection.
• B. Observe the antecubital fossa for inflammation.
• C. Auscultate lung sounds for signs of respiratory distress.
• D. Check for signs of phlebitis or thrombosis along the catheter site.

Correct answer: B

Rationale: Observing the antecubital fossa for inflammation is crucial in clients with a PICC line and fever. Inflammation at the site can indicate infection or complications related to the PICC line. Auscultating lung sounds (choice C) is important but not the priority in this situation. Checking for phlebitis or thrombosis (choice D) is relevant but does not address the immediate concern of identifying infection or complications at the insertion site. Inspecting the PICC insertion site (choice A) is also important but observing the antecubital fossa provides a more direct assessment of potential issues with the PICC line.

3. A client who recently underwent a tracheostomy is being prepared for discharge to home. Which instructions are most important for the nurse to include in the discharge plan?

• A. Teach signs of infection
• B. Teach tracheal suctioning techniques
• C. Educate on humidifying air
• D. Discuss the use of a speaking valve

Correct answer: B

Rationale: The correct answer is B: Teach tracheal suctioning techniques. Tracheal suctioning is crucial for maintaining a clear airway in clients with a tracheostomy. Without proper suctioning, secretions can accumulate and cause airway obstruction or respiratory infections. Educating the client on how to perform suctioning safely is a priority for discharge planning. Choices A, C, and D are important aspects of tracheostomy care, but teaching tracheal suctioning techniques takes precedence due to its direct impact on airway patency and preventing complications.

4. A client with chronic obstructive pulmonary disease (COPD) is prescribed home oxygen therapy. What teaching should the nurse provide?

• A. Ensure that the client uses oxygen continuously at night.
• B. Instruct the client to avoid smoking and exposure to smoke.
• C. Teach the client how to clean and replace the oxygen tubing.
• D. Instruct the client to increase their fluid intake.

Correct answer: C

Rationale: The correct teaching for a client with COPD prescribed home oxygen therapy is to educate them on how to clean and replace the oxygen tubing. This is crucial to prevent infections and ensure the effectiveness of the oxygen delivery system. Option A is not necessary as oxygen therapy is usually prescribed as needed, not continuously at night. While smoking cessation and avoiding smoke exposure are important in COPD management, it is not directly related to home oxygen therapy. Increasing fluid intake is beneficial for some conditions but is not specifically related to home oxygen therapy for COPD.

5. A client with type 2 diabetes mellitus is admitted for frequent hyperglycemic episodes and a glycosylated hemoglobin (A1C) of 10%. Insulin glargine 10 units subcutaneously once a day at bedtime and a sliding scale of insulin aspart every 6 hours are prescribed. What actions should the nurse include in this client's plan of care?

• A. Teach subcutaneous injection technique, site rotation, and insulin management
• B. Coordinate carbohydrate-controlled meals at consistent times and intervals
• C. Review with the client proper foot care and prevention of injury
• D. All of the above

Correct answer: D

Rationale: Effective diabetes management involves comprehensive care, including proper foot care, insulin administration technique, and maintaining carbohydrate consistency with meals. All of these interventions are critical in reducing hyperglycemic episodes and managing diabetes.
