Oxygen Therapy NCLEX Questions Questions
Question 1 of 5
The nurse prepares a patient for a bronchoscopy. What is the most important pre-procedure instruction?
Correct Answer: A
Rationale: The correct answer is A: Avoid eating or drinking for 6-8 hours before the procedure. This instruction is crucial to prevent aspiration during bronchoscopy. Eating or drinking can lead to vomiting, which poses a risk during the procedure. Choice B is incorrect as some medications may need to be avoided before the procedure. Choice C is incorrect as chest discomfort is not expected during the procedure. Choice D is incorrect as deep breathing exercises are not typically required before bronchoscopy.
Question 2 of 5
Which finding in a patient with respiratory distress requires the nurse's immediate intervention?
Correct Answer: A
Rationale: The correct answer is A: Stridor. Stridor is a high-pitched, noisy breathing sound typically heard on inspiration, indicating upper airway obstruction. This finding requires immediate intervention as it can lead to airway compromise and respiratory distress. Explanation for why other choices are incorrect: B: Cough productive of yellow sputum may indicate a respiratory infection but does not necessarily require immediate intervention. C: Oxygen saturation of 92% on 2 L/min oxygen is concerning but not immediately life-threatening. It may require adjustment of oxygen therapy. D: Respiratory rate of 20 breaths per minute falls within the normal range and does not indicate immediate intervention is needed.
Question 3 of 5
The nurse supervises a student nurse who is assigned to take care of a patient with active tuberculosis (TB). Which action, if performed by the student nurse, would require an intervention by the nurse?
Correct Answer: C
Rationale: Rationale: Choice C is correct because hand washing should be performed not just before entering the room but also immediately upon leaving it to prevent the spread of TB. Hand hygiene is crucial in infection control. Choices A, B, and D are incorrect because offering a tissue, wearing a surgical mask, and bringing a snack do not pose a risk of spreading TB and are appropriate actions in caring for a patient with active TB.
Question 4 of 5
A nurse is caring for a patient who is undergoing chemotherapy. Which intervention should be implemented to prevent infection?
Correct Answer: B
Rationale: The correct answer is B: Administer prophylactic antibiotics. This intervention helps prevent infection in the patient undergoing chemotherapy by targeting potential pathogens before they cause harm. Chemotherapy can weaken the immune system, making patients more susceptible to infections. Providing a mask (choice A) may help reduce exposure but does not directly address preventing infection. Repositioning the patient (choice C) is important for preventing complications like pressure ulcers but does not specifically target infection prevention. Performing a sputum culture (choice D) is useful for diagnosing respiratory infections but does not focus on preventing infections proactively. Administering prophylactic antibiotics is a targeted approach to reducing the risk of infection in immunocompromised patients.
Question 5 of 5
A patient with a history of diabetes is experiencing dizziness and confusion. What should the nurse do first?
Correct Answer: D
Rationale: The correct answer is D: Administer an antiemetic. When a patient with diabetes presents with dizziness and confusion, it could indicate hypoglycemia. However, administering glucose without confirming the blood sugar level can be dangerous if the patient's symptoms are not due to low blood sugar. Administering an antiemetic first can help rule out other causes of the symptoms, such as nausea or vomiting, before addressing potential hypoglycemia. Administering glucagon injection or oral glucose should only be done if confirmed hypoglycemia.
