NCLEX Questions on Oxygen Therapy Questions
Question 1 of 5
The nurse is assessing a client with emphysema. Which finding is most consistent with this condition?
Correct Answer: B
Rationale: The correct answer is B: Barrel-shaped chest. In emphysema, air becomes trapped in the lungs, causing overinflation and the chest to take on a barrel shape. This is due to the destruction of alveoli and loss of elastic recoil in the lungs. Frequent nighttime cough (A) may occur but is not specific to emphysema. Cyanosis (C) is more indicative of inadequate oxygenation, which may occur in emphysema but is not specific. Peripheral edema (D) is not typically associated with emphysema.
Question 2 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 3 of 5
A client with COPD is prescribed a corticosteroid inhaler. What should the nurse include in the teaching?
Correct Answer: B
Rationale: The correct answer is B: Rinse your mouth after each use to prevent thrush. Corticosteroid inhalers can increase the risk of oral thrush due to their effect on the immune system. Rinsing the mouth after each use helps to prevent this side effect. A: Using the inhaler only during flare-ups is incorrect as corticosteroid inhalers are often prescribed for daily maintenance to control COPD symptoms. C: Using the inhaler before taking a bronchodilator is not necessary as the order of inhaler use does not impact their effectiveness. D: Taking the medication with meals to prevent stomach upset is incorrect as corticosteroid inhalers are inhaled and do not typically cause stomach upset.
Question 4 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 5 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.
