Chapter 41 Oxygenation NCLEX Questions Questions
Question 1 of 5
A nurse is providing teaching for a client who has a new prescription for a continuous positive airway pressure (CPAP) machine to treat obstructive sleep apnea. Which of the following statements should the nurse include?
Correct Answer: B
Rationale: The correct answer is B: Cover your nose with the CPAP nose. The rationale for this is that the CPAP machine is designed to deliver pressurized air through a mask that covers the nose and/or mouth to keep the airway open during sleep. This ensures that the client receives the appropriate pressure to prevent airway collapse and maintain effective breathing patterns. Choice A is incorrect because using the CPAP mask during the daytime is not necessary and could be uncomfortable for the client. Choice C is incorrect as medications are not administered through the CPAP machine. Choice D is incorrect as supplemental oxygen is not typically needed with CPAP therapy unless prescribed by a healthcare provider for specific medical reasons.
Question 2 of 5
A patient with a history of pulmonary edema is admitted with shortness of breath. What is the nurse's priority action?
Correct Answer: C
Rationale: The correct answer is C: Place the patient in a high Fowler's position. This is the priority action because it helps improve oxygenation by reducing pressure on the diaphragm and increasing lung expansion. Elevating the head of the bed also helps decrease the workload of the heart and improves ventilation. Administering diuretics (choice A) can be important but is not the immediate priority. Assessing lung sounds (choice B) is important but not the most critical action at this moment. Notifying the healthcare provider (choice D) can be done after the patient's immediate needs are addressed.
Question 3 of 5
A nurse is providing discharge teaching to a client with pulmonary hypertension. Which statement indicates a need for further teaching?
Correct Answer: B
Rationale: The correct answer is B because taking over-the-counter decongestants can worsen pulmonary hypertension by increasing pulmonary vascular resistance. A is correct as weight monitoring can detect fluid retention. C is correct as strenuous activities can strain the heart. D is correct as increased shortness of breath may indicate worsening condition.
Question 4 of 5
The nurse is caring for a client with cystic fibrosis. Which intervention is the most effective in managing thick mucus secretions?
Correct Answer: C
Rationale: The correct answer is C: Providing chest physiotherapy. This intervention helps mobilize and clear thick mucus secretions in the lungs, improving breathing and preventing infections. Chest physiotherapy involves techniques like percussion and postural drainage to loosen and remove mucus. Encouraging a low-fat diet (choice A) is important for overall health but not directly related to managing mucus secretions. Administering pancreatic enzymes (choice B) is necessary for digestion in cystic fibrosis but does not address mucus clearance. Encouraging daily exercise (choice D) is beneficial for overall lung function but may not be as effective in managing thick mucus secretions as chest physiotherapy.
Question 5 of 5
A client with a tracheostomy is receiving humidified oxygen. What is the primary purpose of humidification?
Correct Answer: B
Rationale: The correct answer is B: To prevent drying of the respiratory mucosa. Humidification of oxygen helps maintain the moisture of the respiratory mucosa, preventing irritation and damage. Dry mucosa can lead to discomfort, increased risk of infection, and impaired mucociliary function. Choices A, C, and D are incorrect because while promoting healing, enhancing oxygen delivery, and reducing infection risk are important considerations in tracheostomy care, the primary purpose of humidification in this scenario is to prevent mucosal drying.
