NCLEX Questions for Oxygenation Questions
Question 1 of 5
It is especially dangerous to cause a spark in a room where which of the following gases is used?
Correct Answer: D
Rationale: The correct answer is D: Oxygen. Oxygen supports combustion, making it highly flammable. When a spark occurs in an oxygen-rich environment, it can lead to a fire or explosion. Carbon dioxide (A) is non-flammable and inert. Helium (B) is also non-flammable and inert. Nitrogen (C) is non-flammable and does not support combustion. Therefore, the presence of oxygen (D) makes it especially dangerous to cause a spark in a room with oxygen gas.
Question 2 of 5
A nurse is suctioning a client's tracheostomy using an open system. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: Correct Answer: C Rationale: Administering 100% oxygen before suctioning helps prevent hypoxia during the procedure. - Choice A: Using clean technique is incorrect; sterile technique is required for tracheostomy care. - Choice B: Applying suction when inserting the catheter can cause trauma to the airway. - Choice D: Suctioning for 20 seconds each time can lead to hypoxia and should be done for no longer than 10-15 seconds.
Question 3 of 5
A nurse is caring for a client who has pneumonia. Which of the following assessments is the priority?
Correct Answer: A
Rationale: The correct answer is A: Breath sounds. In pneumonia, assessing breath sounds is the priority to monitor for respiratory distress and adequacy of oxygenation. Abnormal breath sounds can indicate worsening pneumonia and the need for immediate intervention. Peripheral edema (B), urinary output (C), and skin turgor (D) are important assessments but are secondary to monitoring respiratory status in a client with pneumonia. It is crucial to prioritize respiratory assessments to ensure timely intervention and prevent respiratory compromise.
Question 4 of 5
A client with pneumonia is placed on a fluid restriction of 1500 mL per day. How should the nurse manage the fluid intake?
Correct Answer: C
Rationale: The correct answer is C because allowing more fluids during the day helps prevent fluid overload and promotes optimal kidney function during waking hours. This approach also reduces the risk of nocturia. Providing fluids mainly at night (Choice A) can lead to disrupted sleep due to frequent bathroom trips. Dividing fluids equally across meals (Choice B) may not be appropriate as it could exceed the daily restriction. Limiting fluid intake to meals only (Choice D) may not provide enough hydration throughout the day, risking dehydration.
Question 5 of 5
A client with a pleural effusion is scheduled for a thoracentesis. What is the nurse's priority pre-procedure intervention?
Correct Answer: B
Rationale: The correct answer is B: Positioning the client sitting upright and leaning forward. This position helps to expose the area for the thoracentesis and prevents puncturing of the underlying structures. It also maximizes lung expansion, making the procedure safer and more effective. Administering analgesics (choice A) is important but not the priority. Ensuring informed consent (choice C) is important but can be done after positioning. Teaching deep breathing exercises (choice D) is also important but not the priority pre-procedure intervention.
