Nursing Fundamentals Oxygenation Questions Questions
Question 1 of 5
Which nursing action is most important for preventing ventilator-associated pneumonia (VAP)?
Correct Answer: B
Rationale: The correct answer is B: Performing frequent oral care with chlorhexidine. This is crucial for preventing VAP as it helps reduce the colonization of bacteria in the oral cavity that can be aspirated into the lungs. Antibiotics (A) are not preventive measures for VAP. Turning the patient (C) helps prevent pressure ulcers, not VAP. Keeping the patient sedated (D) can lead to inadequate respiratory effort and increase the risk of VAP. Overall, proper oral care plays a significant role in reducing the risk of VAP by minimizing bacterial growth in the mouth.
Question 2 of 5
Which is the most effective intervention for preventing pneumonia in a hospitalized patient?
Correct Answer: B
Rationale: The correct answer is B: Promoting early ambulation. Early ambulation helps prevent pneumonia by reducing the risk of atelectasis, a common complication in hospitalized patients that can lead to pneumonia. Moving and mobilizing the patient helps to clear secretions and improve lung function. Antibiotics (choice A) are not recommended for routine prophylaxis due to concerns about antibiotic resistance. While oral care (choice C) and fluid intake (choice D) are important for overall patient health, they do not directly prevent pneumonia in hospitalized patients.
Question 3 of 5
The nurse assesses a patient with a chest tube and notes continuous bubbling in the water-seal chamber. What is the best action?
Correct Answer: B
Rationale: The correct answer is B: Check for loose connections in the tubing. Continuous bubbling in the water-seal chamber indicates an air leak. Checking for loose connections ensures proper functioning of the chest tube drainage system. Clamping the chest tube (choice A) can lead to tension pneumothorax. Replacing the entire system (choice C) is unnecessary and costly. Notifying the healthcare provider (choice D) can be done after checking for loose connections.
Question 4 of 5
Which patient statement indicates a need for further teaching about asthma management?
Correct Answer: A
Rationale: The correct answer is A because using a rescue inhaler before meals is not a recommended practice for asthma management. Rescue inhalers are typically used for immediate relief during asthma attacks, not as a preventive measure before meals. This statement indicates a misunderstanding of how to use the inhaler properly. Choice B is correct as it shows an understanding of avoiding triggers to manage asthma symptoms. Choice C is correct because taking the long-acting inhaler as prescribed is an essential part of asthma management. Choice D is also correct as carrying the inhaler at all times ensures readiness for any asthma exacerbation.
Question 5 of 5
The nurse is educating a patient with chronic bronchitis about using a metered-dose inhaler (MDI). What statement by the patient indicates understanding?
Correct Answer: A
Rationale: Rationale for Correct Answer (A): Shaking the inhaler before each use ensures proper mixing of the medication for consistent dose delivery. This statement indicates understanding of the correct technique for using a metered-dose inhaler. Summary of Incorrect Choices: B: Exhaling forcefully after inhaling the medication is not a recommended step and can reduce medication deposition in the lungs. C: Cleaning the inhaler once a month is not frequent enough, as it should be cleaned regularly to prevent buildup and ensure proper functioning. D: Taking the inhaler right before meals is not a specific instruction related to the correct technique for using a metered-dose inhaler.
