Chapter 41 Oxygenation NCLEX Questions Questions
Question 1 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 2 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 3 of 5
A client with asthma is using a metered-dose inhaler (MDI) for the first time. Which instruction is most important?
Correct Answer: C
Rationale: The correct answer is C: Hold your breath for 10 seconds after inhaling. This instruction is crucial as it allows the medication to reach deep into the lungs for better absorption and effectiveness. Holding the breath helps prevent the medication from being exhaled too soon. Choice A is incorrect as shaking the inhaler is not necessary for all types of MDIs. Choice B is not the most important instruction as exhaling completely is a general step for using inhalers but not the most critical. Choice D is incorrect as waiting between puffs allows for better absorption and prevents overdose.
Question 4 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 5 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.
