NCLEX Questions on Oxygenation and Perfusion Questions
Question 1 of 5
A nurse is caring for a patient with a history of asthma. The patient is experiencing shortness of breath. What is the priority intervention?
Correct Answer: A
Rationale: The correct answer is A: Administer a bronchodilator. The priority intervention for a patient with asthma experiencing shortness of breath is to administer a bronchodilator to help open up the airways and improve breathing. Bronchodilators work quickly to relieve acute symptoms of asthma by relaxing the muscles around the airways. This intervention is crucial in managing an acute asthma exacerbation. Summary: - Option B: Administer insulin therapy is incorrect because it is not indicated for managing asthma exacerbation. - Option C: Administer short-acting bronchodilators is partially correct but not as specific as option A, which specifies the immediate need for bronchodilator therapy. - Option D: Administer corticosteroids is important for long-term control of asthma but not the priority intervention in an acute exacerbation where immediate relief is needed.

Question 3 of 5
A patient diagnosed with active tuberculosis (TB) is homeless and has a history of alcohol abuse. Which intervention by the nurse will be most effective in ensuring adherence with the treatment regimen?
Correct Answer: C
Rationale: Providing daily meals and medication at a community center addresses barriers like homelessness and ensures directly observed therapy (DOT), improving adherence.
Question 4 of 5
A patient with a possible pulmonary embolism complains of chest pain and difficulty breathing. The nurse finds a heart rate of 142 beats/min, blood pressure of 100/60 mm Hg, and respirations of 42 breaths/min. Which action should the nurse take first?
Correct Answer: D
Rationale: Elevating the head improves breathing and oxygenation immediately, addressing acute distress while awaiting further intervention.
Question 5 of 5
The nurse is caring for a patient with chronic obstructive pulmonary disease (COPD). Which information obtained from the patient would prompt the nurse to consult with the health care provider before administering the prescribed theophylline?
