NCLEX Questions on Oxygenation and Perfusion Questions
Question 1 of 5
A nurse is caring for a patient with a history of diabetes who is experiencing blurred vision. What is the priority action?
Correct Answer: C
Rationale: The correct answer is C: Administer insulin. Blurred vision in a patient with a history of diabetes could indicate hyperglycemia. Administering insulin would help lower blood glucose levels and alleviate the blurred vision. Monitoring blood glucose levels (choice A) is important but not the priority when the patient is already experiencing symptoms. Administering insulin (choices B and D) is the immediate action needed to address the high blood glucose levels causing the blurred vision.
Question 2 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 who has a history of chronic obstructive pulmonary disease (COPD) was hospitalized for increasing shortness of breath and chronic hypoxemia (SaO₂ levels of 89% to 90%). In planning for discharge, which action by the nurse will be most effective in improving compliance with discharge teaching?
Correct Answer: C
Rationale: Including the caregiver ensures support and reinforcement of teaching, improving compliance in COPD patients.
Question 4 of 5
Which action should the nurse take first when a patient develops epistaxis?

Question 5 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?
