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. During an assessment of a client with congestive heart failure, the nurse is most likely to hear which of the following upon auscultation of the heart?

• A. S3 ventricular gallop
• B. Apical click
• C. Systolic murmur
• D. Split S2

Correct answer: A

Rationale: Correct Answer: An S3 ventricular gallop is an abnormal heart sound commonly heard in clients with congestive heart failure. This sound is indicative of fluid overload or volume expansion in the ventricles, which is often present in heart failure. <br> Incorrect Answers: <br> B: An apical click is not typically associated with congestive heart failure. <br> C: A systolic murmur may be heard in various cardiac conditions but is not specific to congestive heart failure. <br> D: A split S2 refers to a normal heart sound caused by the closure of the aortic and pulmonic valves at slightly different times during inspiration, not directly related to congestive heart failure.

3. A client presents with a suspected infection and has a fever of 102°F. What is the nurse's immediate priority?

• A. Administer antipyretics as ordered
• B. Take a blood culture before administering antibiotics
• C. Encourage fluid intake to prevent dehydration
• D. Monitor vital signs every hour

Correct answer: B

Rationale: The immediate priority for a client with a suspected infection and fever is to take a blood culture before administering antibiotics. This step is crucial to identify the causative organism and ensure appropriate treatment. Administering antipyretics or encouraging fluid intake are important but should come after obtaining the blood culture to avoid interfering with test results. Monitoring vital signs, although essential, is not the immediate priority compared to identifying the infectious agent.

4. A client receiving radiation therapy for breast cancer reports dry, peeling skin at the treatment site. What action should the nurse recommend?

• A. Apply lotion to the treatment area.
• B. Use mild soap and water to cleanse the area.
• C. Cover the area with a sterile dressing.
• D. Allow the skin to air dry after washing.

Correct answer: B

Rationale: The correct recommendation for a client with dry, peeling skin at a radiation therapy treatment site is to use mild soap and water to cleanse the area. This approach helps in preventing skin irritation and reduces the risk of infection. Applying lotion (Choice A) may further irritate the skin due to the chemicals present in the lotion. Covering the area with a sterile dressing (Choice C) is not necessary unless there is an open wound that needs protection. Allowing the skin to air dry after washing (Choice D) may lead to further dryness and peeling.

5. A male client with schizophrenia is socially reclusive and pacing in the hallway. What is the most important intervention for the nurse to implement?

• A. Take the client's temperature and blood pressure.
• B. Encourage the client to rest.
• C. Plan an activity that includes physical exercise.
• D. Carefully observe the client throughout the shift.

Correct answer: D

Rationale: The correct answer is to carefully observe the client throughout the shift. In this situation, the client's behavior suggests agitation and restlessness, which could potentially escalate. Observation is crucial to monitor any changes in behavior, assess for signs of distress, and ensure the client's safety. Taking the client's temperature and blood pressure (Choice A) may not address the immediate need for managing the client's behavior. Encouraging the client to rest (Choice B) might not be effective if the client is highly agitated. Planning an activity that includes physical exercise (Choice C) could exacerbate the situation rather than address the current behavior. Therefore, the priority is to observe the client closely to provide appropriate support and intervention as needed.
