NCLEX Questions on Oxygenation and Perfusion Questions
Question 1 of 5
A nurse is caring for a patient with a history of heart failure. The patient is experiencing fatigue and weakness. What is the priority intervention?
Correct Answer: A
Rationale: The correct answer is A: Administer oxygen. In heart failure, fatigue and weakness can be due to poor oxygenation. Administering oxygen helps improve oxygen levels, alleviating symptoms. Insulin (B) is not indicated for fatigue in heart failure. Antibiotics (C) are not necessary unless there is a confirmed infection. Beta-blockers (D) may be part of the treatment plan but addressing oxygenation is the priority in this scenario.
Question 2 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 3 of 5
Which action should the nurse take first when a patient develops epistaxis?
Correct Answer: B
Rationale: Applying pressure is the first-line, non-invasive action to stop epistaxis.
Question 4 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 5 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.
