Oxygen Cycle Questions and Answers Questions
Question 1 of 5
The nurse is teaching a patient with obstructive sleep apnea about using a CPAP machine. Which statement by the patient indicates a need for further teaching?
Correct Answer: B
Rationale: Correct Answer: B - "I should sleep on my back for better airflow." Rationale: 1. Sleeping on the back can worsen obstructive sleep apnea by causing the tongue and soft tissues to block the airway. 2. The optimal sleeping position for CPAP therapy is usually on the side to maintain open airways. 3. Choices A, C, and D are correct as consistent CPAP usage, regular cleaning, and weight loss can improve sleep apnea symptoms.
Question 2 of 5
The nurse is caring for a patient with chest trauma. Which finding is most concerning?
Correct Answer: B
Rationale: The correct answer is B: Paradoxical chest wall movement. This finding is most concerning because it indicates a flail chest, a serious condition where a segment of the chest wall moves in the opposite direction of the rest of the chest during breathing, leading to respiratory compromise and potential lung injury. This requires immediate medical intervention. A: Mild chest wall bruising is less concerning as it may be a common finding in chest trauma without indicating severe underlying issues. C: A respiratory rate of 20 breaths per minute falls within the normal range and may not necessarily indicate a critical condition. D: Subcutaneous emphysema near the injury site can be concerning but is typically not as immediately critical as paradoxical chest wall movement in terms of respiratory compromise.
Question 3 of 5
Which statement by a patient with a new diagnosis of tuberculosis requires correction?
Correct Answer: C
Rationale: The correct answer is C. This statement is incorrect because stopping tuberculosis medications prematurely can lead to treatment failure and the development of drug-resistant strains. Patients must complete the full course of treatment to ensure the infection is completely eradicated. Wearing a mask to prevent spreading the infection, taking medication for at least 6 months as prescribed, and scheduling regular follow-up appointments are all essential steps in managing tuberculosis effectively.
Question 4 of 5
A nurse is teaching a patient how to manage allergic rhinitis. What is the most important point to include?
Correct Answer: B
Rationale: The correct answer is B: Identify and avoid environmental triggers. This is the most important point because it addresses the root cause of allergic rhinitis, which is exposure to allergens. By identifying and avoiding triggers such as pollen, dust mites, and pet dander, the patient can effectively manage their symptoms. Using oral antihistamines preemptively (choice A) may provide some relief, but does not address the underlying cause. Washing hands frequently (choice C) is important for preventing infections but not directly related to managing allergic rhinitis. Limiting corticosteroid nasal sprays (choice D) is incorrect as they are commonly used and effective in managing allergic rhinitis symptoms without significant systemic effects when used as directed.
Question 5 of 5
The nurse is preparing a patient for thoracentesis. Which position is most appropriate?
Correct Answer: B
Rationale: The correct position for thoracentesis is sitting upright and leaning forward (Choice B). This position allows better access to the thoracic cavity, facilitating the procedure and reducing the risk of complications. Sitting upright helps expand the intercostal space, making it easier to insert the needle accurately. Leaning forward also helps the patient breathe more comfortably during the procedure. Supine position (Choice A) with the head of the bed flat may not provide optimal access to the thoracic cavity. Lying on the affected side (Choice C) may not allow proper visualization and access to the site. Prone position with arms raised above the head (Choice D) is not suitable for thoracentesis as it does not facilitate proper access to the thoracic cavity.
