Oxygenation NCLEX Questions with Rationale Questions
Question 1 of 5
A nurse is evaluating a client's understanding of the use of a metered-dose inhaler (MDI). Which of the following actions indicates correct use?
Correct Answer: A
Rationale: Correct Answer: A Rationale: Exhaling fully before using the MDI helps create space in the lungs for the medication to reach deeper into the airways upon inhalation. This maximizes the effectiveness of the medication. Holding the breath for a few seconds after inhalation also allows the medication to be absorbed properly. Shaking the inhaler after use is not recommended as it may cause the medication to clump. Using the inhaler while lying flat can lead to improper inhalation technique and reduced effectiveness.
Question 2 of 5
A client with asthma is admitted for an acute exacerbation. Which medication should the nurse administer first?
Correct Answer: A
Rationale: The correct answer is A: Short-acting beta2-agonist. During an acute asthma exacerbation, bronchodilation is the priority to relieve airway constriction and improve breathing. Short-acting beta2-agonists like albuterol act quickly to relax bronchial smooth muscles, providing immediate relief. This medication is the first-line treatment for acute exacerbations as it addresses the underlying bronchoconstriction. Inhaled corticosteroids (B) are used for long-term management and prevention of asthma symptoms, not for immediate relief. Leukotriene receptor antagonists (C) are typically used as adjunct therapy and not for acute exacerbations. Long-acting beta2-agonists (D) are used for maintenance therapy and should not be used as the initial treatment during an acute exacerbation.
Question 3 of 5
A client with COPD reports fatigue during activities of daily living. What intervention should the nurse recommend?
Correct Answer: C
Rationale: The correct answer is C: Rest between activities to conserve energy. This intervention is appropriate for a client with COPD experiencing fatigue as it helps prevent overexertion and conserves energy. Resting between activities allows the client to pace themselves, reducing the risk of worsening symptoms. Performing all activities in the morning (choice A) may not address the fatigue throughout the day. Using oxygen only during strenuous activities (choice B) does not address the underlying issue of energy conservation. Increasing activity level to build endurance (choice D) may lead to further fatigue and exacerbate symptoms. Overall, choice C is the most suitable intervention for managing fatigue in a client with COPD.
Question 4 of 5
A client recovering from a thoracentesis reports feeling lightheaded and short of breath. What is the nurse's priority action?
Correct Answer: B
Rationale: The correct answer is B: Assess the client for signs of pneumothorax. Following a thoracentesis, lightheadedness and shortness of breath could indicate a pneumothorax, a potential complication where air accumulates in the pleural space. The priority action is to assess for signs of pneumothorax, such as decreased breath sounds, chest pain, and respiratory distress, as it requires immediate intervention to prevent further complications. Encouraging slow, deep breaths (A) may worsen a pneumothorax. Administering pain medication (C) is not the priority when respiratory distress is present. Positioning the client flat (D) may exacerbate a pneumothorax.
Question 5 of 5
The nurse is assessing a client with sleep apnea. Which symptom is most commonly associated with this condition?
Correct Answer: A
Rationale: The correct answer is A: Morning headaches. 1. Sleep apnea causes intermittent pauses in breathing during sleep, leading to low oxygen levels and frequent awakenings, resulting in morning headaches. 2. Frequent nighttime urination (B) is not typically associated with sleep apnea. 3. Unexplained weight loss (C) is not a common symptom of sleep apnea. 4. Persistent dry cough (D) is more commonly associated with conditions like asthma or GERD, not sleep apnea.
