Question 1 of 5
The nurse is educating a client with asthma about using an inhaler. Which statement indicates a need for further teaching?
Correct Answer: B
Rationale: The correct answer is B: "I should breathe in quickly when using the inhaler." This statement is incorrect because the client should actually breathe in slowly and deeply when using an inhaler to ensure proper medication delivery to the lungs. Breathing in quickly can lead to inadequate medication absorption. Choices A, C, and D are correct statements. A: Shaking the inhaler ensures proper mixing of the medication. C: Rinsing the mouth after using a steroid inhaler helps prevent oral thrush. D: Waiting at least one minute between puffs allows optimal medication delivery.
Question 2 of 5
A client with pulmonary fibrosis is being treated with supplemental oxygen. What is the primary goal of oxygen therapy in this condition?
Correct Answer: B
Rationale: The primary goal of oxygen therapy in pulmonary fibrosis is to reduce the work of breathing. Pulmonary fibrosis causes stiffening and scarring of the lung tissue, making breathing more difficult. Supplemental oxygen helps improve oxygen levels in the blood, reducing the effort required to breathe. This can alleviate symptoms such as shortness of breath and improve the client's quality of life. Explanation of why other choices are incorrect: A: Oxygen therapy does not cure pulmonary fibrosis. It only helps manage symptoms. C: Oxygen therapy does not eliminate the need for medications in pulmonary fibrosis. Medications may still be necessary to manage the underlying condition. D: Oxygen therapy does not aim to prevent respiratory alkalosis in pulmonary fibrosis. It primarily focuses on improving oxygenation and reducing the work of breathing.
Question 3 of 5
The nurse is teaching a client with pneumonia about incentive spirometer use. What statement indicates correct understanding?
Correct Answer: B
Rationale: The correct answer is B: "I will inhale deeply into the device to expand my lungs." This statement indicates correct understanding because using an incentive spirometer involves inhaling deeply to fully expand the lungs, promoting better lung ventilation and preventing complications like pneumonia. Choice A is incorrect because using the device once every few hours may not be frequent enough. Choice C is incorrect because the spirometer should be used proactively, not just when feeling short of breath. Choice D is incorrect because exhaling quickly is not the correct technique for using an incentive spirometer.
Question 4 of 5
The nurse is caring for a client who is intubated and on mechanical ventilation. Which action is most effective in preventing ventilator-associated pneumonia (VAP)?
Correct Answer: B
Rationale: The correct answer is B: Providing oral care with chlorhexidine. This is because oral care helps reduce the bacteria in the mouth that can be aspirated into the lungs, leading to VAP. Regular oral care with chlorhexidine can prevent colonization of harmful bacteria in the oral cavity, reducing the risk of VAP. Administering antibiotics won't prevent VAP but treat infections. Suctioning every hour can increase the risk of infection, and elevating the head of the bed to 15 degrees may help prevent aspiration but is not as effective as proper oral care in preventing VAP.
Question 5 of 5
A client is receiving oxygen via a non-rebreather mask. What is the most important nursing assessment?
Correct Answer: A
Rationale: The correct answer is A: Ensuring the reservoir bag remains inflated. This is crucial as it indicates the client is receiving the intended high-flow oxygen without rebreathing exhaled CO2. If the bag deflates, it suggests a leak or inadequate flow. Option B is not relevant as the flow rate for a non-rebreather mask is typically higher. Option C is less critical than ensuring oxygen delivery. Option D is important but not the priority when the client's oxygenation is at stake.
