Chapter 41 Oxygenation NCLEX Questions Questions
Question 1 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.
Question 2 of 5
The nurse is teaching a client with cystic fibrosis about pancreatic enzyme replacement therapy. When should the client take the enzymes?
Correct Answer: A
Rationale: The correct answer is A: Before meals and snacks. This is because pancreatic enzymes need to be taken with food to aid in digestion. Taking enzymes before meals ensures they can mix with food in the stomach and help break down fats, proteins, and carbohydrates. Option B (At bedtime only) is incorrect as enzymes should be taken with meals to be effective. Option C (On an empty stomach) is incorrect because enzymes need food to digest. Option D (Every 6 hours, regardless of meals) is incorrect as enzymes should be taken with each meal to optimize digestion.
Question 3 of 5
The nurse is assessing a client with acute asthma exacerbation. Which finding indicates the condition is worsening?
Correct Answer: A
Rationale: The correct answer is A: Decreased wheezing on auscultation. In acute asthma exacerbation, decreased wheezing indicates airway constriction worsening, leading to decreased airflow. Increased respiratory rate (B) signifies increased effort to breathe due to worsening condition. Oxygen saturation improvement (C) is positive but doesn't indicate worsening. Client reporting reduced shortness of breath (D) is also positive and suggests improvement.
Question 4 of 5
A client with asthma is prescribed a corticosteroid inhaler. What should the nurse emphasize in client teaching?
Correct Answer: B
Rationale: The correct answer is B: Rinse your mouth after each use to prevent thrush. This is crucial because corticosteroid inhalers can increase the risk of developing oral thrush due to their effect on the oral mucosa. Rinsing the mouth after each use helps remove any medication residue and reduces the risk of fungal infections. Option A is incorrect as corticosteroid inhalers are maintenance medications, not just for asthma attacks. Option C is incorrect because bronchodilators should be used before corticosteroid inhalers. Option D is incorrect as there is no need to specifically increase fluid intake after using the inhaler.
Question 5 of 5
After the nurse has received a change-of-shift report, which patient should the nurse assess first?
Correct Answer: C
Rationale: The nurse should assess the patient with possible lung cancer who has just returned after bronchoscopy first because this patient may be at risk for complications such as bleeding, respiratory distress, or infection post-procedure. Assessing this patient promptly allows for early identification and intervention if any issues arise. The other choices present conditions that may require assessment but do not have the immediate post-procedure risk associated with bronchoscopy. The patient with pneumonia (choice A) may need assessment for respiratory status, but the urgency is lower than the post-bronchoscopy patient. The patient with chronic bronchitis (choice B) may require monitoring, but the low forced vital capacity does not indicate an acute issue. The patient with hemoptysis and a positive tuberculin skin test (choice D) may need further evaluation for tuberculosis, but the immediate risk is lower than the post-bronchoscopy patient.
