NCLEX Questions on Oxygen Therapy Questions
Question 1 of 5
The nurse is assessing a client with pleural effusion. Which finding is most expected?
Correct Answer: B
Rationale: The correct answer is B: Dullness to percussion over the affected area. Pleural effusion is an accumulation of fluid in the pleural space, causing dullness to percussion due to the fluid-filled space. Bilateral crackles (A) would suggest a different condition like pulmonary edema. Hyperresonance (C) would be indicative of pneumothorax. Increased fremitus (D) would typically be found in conditions with lung consolidation, such as pneumonia, not pleural effusion. Therefore, the most expected finding in pleural effusion is dullness to percussion over the affected area due to the presence of fluid.
Question 2 of 5
A nurse is choosing a catheter to use to suction a patient's endotracheal tube via an open system. On which variable would the nurse base the size of the chosen catheter?
Correct Answer: B
Rationale: The correct answer is B: The size of the endotracheal tube. The nurse should base the size of the chosen catheter on the size of the endotracheal tube to ensure proper suctioning and prevent injury. Using a catheter that is too large can damage the airway, while using one that is too small may not effectively remove secretions. Age, type of secretions, and patient's height and weight do not directly determine the appropriate catheter size for endotracheal suctioning. It is crucial to match the catheter size with the endotracheal tube size for safe and effective suctioning.
Question 3 of 5
The nurse observes a student nurse caring for a patient with active tuberculosis (TB). Which action, if performed by the student nurse, would require an intervention by the nurse?
Correct Answer: B
Rationale: The correct answer is B because wearing a surgical face mask before visiting a patient with active TB is incorrect. The proper personal protective equipment for TB includes an N95 respirator to prevent transmission. Option A is correct as providing a tissue does not pose a risk. Option C is fine as long as the snack is not consumed in the patient's room. Option D is also correct as hand washing is a standard precaution. Therefore, wearing a surgical face mask is the only incorrect action that requires intervention.
Question 4 of 5
The nurse is teaching a patient with COPD about the use of a metered-dose inhaler. Which action by the patient indicates a need for further instruction?
Correct Answer: C
Rationale: The correct answer is C because exhaling quickly after inhaling the medication can lead to the medication being exhaled before it reaches the lungs. Holding the breath for 5 seconds after inhalation (A) allows the medication to be absorbed. Activating the inhaler during inhalation (B) ensures the medication is properly delivered. Waiting 1 minute between puffs (D) allows for optimal medication absorption.
Question 5 of 5
Which nursing action is most appropriate when caring for a patient with a suspected pulmonary embolism?
Correct Answer: B
Rationale: The correct answer is B: Initiate oxygen therapy. This is the most appropriate nursing action for a patient with a suspected pulmonary embolism because it helps improve oxygenation and alleviate respiratory distress, which are critical in the management of this condition. Oxygen therapy can help support the patient's respiratory function and prevent hypoxia. Positioning the patient flat in bed (choice A) may worsen respiratory distress due to decreased lung expansion. Chest physiotherapy (choice C) is not recommended as it may dislodge the embolism and worsen the condition. Encouraging ambulation (choice D) can be dangerous as it may lead to dislodgment of the clot and subsequent complications.
