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. What do you call a system involving other government Ministries, Non-Governmental Organizations, Politicians, Policy makers, Senior managers, the Community, Church organizations, and other concerned bodies and users of services?
- A. Community participation
- B. Peer consultation
- C. Multi-sectoral approach
- D. Appropriate technology
Correct answer: C
Rationale: A multi-sectoral approach involves collaboration among various sectors and stakeholders to address complex issues comprehensively. In this context, it ensures that different entities work together to provide inclusive and effective services. Choice A, 'Community participation,' focuses more on the involvement of the community specifically. Choice B, 'Peer consultation,' pertains to seeking advice or input from peers within the same field. Choice D, 'Appropriate technology,' refers to the use of suitable technology for a particular situation, which is not the primary focus of the described system.
3. A client is being treated for tuberculosis (TB). Which of these statements indicates the client understands the transmission of TB?
- A. I need to wear a mask when I go out in public to prevent spreading the infection.
- B. I need to take my medication as prescribed to prevent spreading the infection to others.
- C. I need to cover my mouth when I cough to prevent spreading the infection.
- D. I need to isolate myself from others until my treatment is complete to prevent spreading the infection.
Correct answer: A
Rationale: The correct answer is A because wearing a mask in public can help prevent the spread of TB to others. Choice B is incorrect as taking medication as prescribed helps in treating the infection within the individual but does not directly prevent spreading it to others. Choice C is important for respiratory hygiene but may not be sufficient to prevent transmission. Choice D, isolation until treatment is complete, is crucial for preventing the spread but is not specifically about understanding transmission.
4. The nurse is assessing the thorax and lungs of a client who is experiencing respiratory difficulty. Which finding is most indicative of respiratory distress?
- A. Contractions of the sternocleidomastoid muscle.
- B. Respiratory rate of 20 breaths/min
- C. Downward movement of diaphragm with inspiration
- D. A pulse oximetry reading of SpO2 95%
Correct answer: A
Rationale: The correct answer is A: Contractions of the sternocleidomastoid muscle. Contractions of the sternocleidomastoid muscle suggest that the client is using accessory muscles to breathe, which is a clear sign of respiratory distress. This finding indicates that the client is working harder to breathe, typically seen in conditions like asthma, COPD, or respiratory failure. Choices B, C, and D are not the most indicative of respiratory distress. A respiratory rate of 20 breaths/min falls within the normal range. Downward movement of the diaphragm with inspiration is a normal finding indicating effective diaphragmatic breathing. A pulse oximetry reading of SpO2 95% is within the normal range and does not necessarily indicate respiratory distress.
5. The nurse has been teaching a client with congestive heart failure about proper nutrition. The selection of which lunch indicates the client has learned about sodium restriction?
- A. Cheese sandwich with a glass of 2% milk
- B. Sliced turkey sandwich and canned pineapple
- C. Cheeseburger and baked potato
- D. Mushroom pizza and ice cream
Correct answer: B
Rationale: The correct answer is B. A sliced turkey sandwich and canned pineapple are good choices for a client with congestive heart failure who is learning about sodium restriction. Turkey is generally lower in sodium compared to cheese, and canned fruits like pineapple typically have lower sodium content. Choices A, C, and D are less suitable as they contain higher levels of sodium, such as cheese, cheeseburger, baked potato, mushroom pizza, and ice cream, which are not ideal for a client needing to restrict sodium intake.
