NCLEX Questions Oxygen Therapy Questions
Question 1 of 5
A nurse is caring for a client who requires 1 L of oxygen. Which of the following oxygen delivery devices should the nurses expect to use?
Correct Answer: A
Rationale: The correct answer is A: Nasal cannula. It delivers low to medium concentrations of oxygen, suitable for clients requiring 1 L of oxygen. Nasal cannula is comfortable and allows for mobility. Other choices are incorrect: B delivers high concentrations, C has a reservoir bag, and D delivers low to moderate concentrations but is not the most appropriate for 1 L.
Question 2 of 5
A nurse is reviewing discharge instructions with a client who has chronic obstructive pulmonary disease (COPD). Which of the following should the nurse include?
Correct Answer: C
Rationale: Rationale for Correct Answer (C): 1. Engaging in regular moderate exercise helps improve lung function and overall physical endurance in COPD patients. 2. Exercise can help strengthen respiratory muscles and reduce shortness of breath. 3. Regular exercise can also improve circulation and promote better oxygen delivery to tissues. Summary of Incorrect Choices: A. Avoiding fluid intake to reduce mucus production is incorrect as hydration is important for thinning mucus and preventing dehydration. B. Using a bronchodilator after exercising may be necessary, but it is not the most essential discharge instruction. D. Sleeping in a fully supine position is not recommended for COPD patients as it can worsen breathing difficulties.
Question 3 of 5
In providing care to a patient admitted with acute asthma exacerbation, the nurse prepares which 'rescue' medication for administration first?
Correct Answer: D
Rationale: The correct answer is D: Short-acting beta2-adrenergic agonists. In acute asthma exacerbation, rapid bronchodilation is crucial for symptom relief. Short-acting beta2-agonists like albuterol act quickly to dilate the airways, providing immediate relief of bronchospasm and improving airflow. This medication is the first-line treatment for acute asthma attacks as it targets the underlying issue of bronchoconstriction. A: Inhaled anti-inflammatories, like corticosteroids, are essential for long-term control of asthma but are not used as rescue medications for acute exacerbations. B: Mucolytics help in thinning mucus but do not address the bronchoconstriction seen in acute asthma exacerbations. C: Long-acting beta2-agonists are used for maintenance therapy in asthma management and are not intended for quick relief during acute attacks.
Question 4 of 5
A client recovering from a pneumonectomy is placed in a semi-Fowler's position. What is the primary reason for this positioning?
Correct Answer: C
Rationale: The correct answer is C: To promote lung expansion. Placing the client in a semi-Fowler's position helps improve ventilation by allowing the lungs to expand more fully, aiding in gas exchange. This position also optimizes diaphragmatic function. A is incorrect because preventing atelectasis is more related to deep breathing exercises. B is incorrect as reducing pressure on the suture line is not the primary purpose of semi-Fowler's position. D is incorrect as preventing aspiration of secretions is not directly related to the positioning of a client recovering from a pneumonectomy.
Question 5 of 5
A client with bronchiectasis has a large amount of foul-smelling sputum. What intervention should the nurse prioritize?
Correct Answer: D
Rationale: The correct answer is D because postural drainage therapy helps mobilize and clear secretions from the bronchiectatic areas, reducing the risk of infection from stagnant sputum. It is a priority intervention to improve airway clearance and prevent further lung damage. Encouraging frequent coughing and deep breathing (A) may help clear secretions but may not be as effective as postural drainage. Increasing fluid intake (B) may help liquefy secretions, but without proper clearance, it may not address the underlying issue. Administering antibiotics (C) is important if there is an infection, but it does not directly address the need for sputum clearance in bronchiectasis.
