NCLEX Questions on Oxygen Therapy Questions
Question 1 of 5
A client with pulmonary edema is receiving furosemide (Lasix). Which assessment finding indicates the medication is effective?
Correct Answer: A
Rationale: The correct answer is A: Decreased peripheral edema. Furosemide is a diuretic that helps reduce fluid volume in the body, which leads to decreased edema. Peripheral edema is a common manifestation of pulmonary edema, so a decrease in peripheral edema indicates that the furosemide is effectively reducing fluid overload. Increased respiratory rate (B) is a sign of respiratory distress, not medication effectiveness. Blood pressure of 150/90 mmHg (C) is within normal range and not a specific indicator of furosemide effectiveness. Weight gain of 2 kg in 24 hours (D) is a sign of fluid retention and not a desirable outcome when treating pulmonary edema.
Question 2 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 3 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 4 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 5 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.
