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 receiving total parenteral nutrition (TPN) reports nausea and dizziness. What action should the nurse take first?

• A. Check the client's blood glucose level.
• B. Check the client's vital signs and blood pressure.
• C. Decrease the infusion rate of TPN.
• D. Administer antiemetic medication as prescribed.

Correct answer: B

Rationale: When a client receiving total parenteral nutrition (TPN) reports symptoms like nausea and dizziness, the first action the nurse should take is to check the client's vital signs and blood pressure. This assessment helps determine the client's overall stability and can provide crucial information to guide further interventions. Checking the blood glucose level (Choice A) may be relevant but is not the priority in this situation. Decreasing the infusion rate of TPN (Choice C) may be necessary but should be based on assessment findings. Administering antiemetic medication (Choice D) should not be the initial action without first assessing the client's vital signs.

3. The client has been diagnosed with hypertension, and the nurse is providing education on dietary changes. Which food should the client be advised to avoid?

• A. Bananas
• B. Processed meats
• C. Low-fat yogurt
• D. Whole grains

Correct answer: B

Rationale: Processed meats should be avoided by clients with hypertension as they are high in sodium, which can contribute to elevated blood pressure. It is essential to limit the intake of high-sodium foods to help manage hypertension. Bananas, low-fat yogurt, and whole grains are generally beneficial for heart health due to their nutrient content and should not be avoided in a heart-healthy diet.

4. While caring for a client's postoperative dressing, the nurse observes purulent drainage at the wound. Before reporting this finding to the healthcare provider, the nurse should review which of the client's laboratory values?

• A. White blood cell count
• B. Hemoglobin
• C. Serum creatinine
• D. Culture for sensitive organisms

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.

5. The nurse is providing discharge teaching to a client with gastroesophageal reflux disease (GERD). Which instruction should the nurse include in the teaching?

• A. Increase fluid intake with meals
• B. Avoid lying down for at least 30 minutes after eating
• C. Eat small, frequent meals throughout the day
• D. Consume spicy foods in moderation

Correct answer: C

Rationale: The correct instruction for the nurse to include in the teaching for a client with GERD is to eat small, frequent meals throughout the day. This recommendation helps reduce symptoms by preventing the stomach from becoming overly full, which can increase pressure on the lower esophageal sphincter and lead to acid reflux. Choices A, B, and D are incorrect because increasing fluid intake with meals can exacerbate GERD symptoms, lying down after eating can worsen reflux, and consuming spicy foods can trigger acid reflux in individuals with GERD.
