Nursing Fundamentals Oxygenation Questions Questions
Question 1 of 5
The nurse teaches a patient with asthma how to use a peak flow meter. Which statement indicates the need for additional instruction?
Correct Answer: B
Rationale: The correct answer is B because using the peak flow meter only when feeling short of breath may not provide an accurate assessment of lung function. The peak flow meter should be used regularly to monitor lung function, not just when symptoms are present. Option A is correct as exhaling forcefully ensures an accurate reading. Option C is correct as recording the highest reading is recommended for tracking progress. Option D is correct as using the meter before and after medications helps evaluate the effectiveness of treatment.
Question 2 of 5
A patient with a chest tube has no drainage in the collection chamber for 2 hours. What is the nurse's best action?
Correct Answer: C
Rationale: The correct answer is C: Assess for kinks or obstructions in the tubing. This is the best action because lack of drainage in the collection chamber could indicate a blockage in the tubing, preventing proper drainage. By assessing for kinks or obstructions first, the nurse can identify and address the issue causing the lack of drainage. Repositioning the patient may not address the underlying problem, clamping the chest tube could cause a tension pneumothorax, and removing the chest tube without addressing the cause could lead to complications.
Question 3 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 4 of 5
Which intervention is most important for a patient with rib fractures to prevent complications?
Correct Answer: C
Rationale: The correct answer is C because administering pain medication before deep breathing helps manage pain during deep breathing exercises, which are essential for preventing atelectasis and pneumonia in patients with rib fractures. Shallow breathing (Choice B) can lead to complications, so it should not be encouraged. Applying a rib binder (Choice A) may restrict chest expansion and hinder deep breathing. Restricting fluid intake (Choice D) is not directly related to preventing complications from rib fractures.
Question 5 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.
