Chapter 41 Oxygenation NCLEX Questions Questions
Question 1 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 2 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 3 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 4 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 5 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.
