Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
A home health nurse is discussing the dangers of carbon monoxide poisoning with a client. Which of the following information should the nurse include?
Correct Answer: C
Rationale: Carbon monoxide (CO) is odorless and colorless (A is incorrect). Water heater inspections (B) are relevant but not the primary focus. CO damages tissues by binding to hemoglobin (D) forming carboxyhemoglobin which impairs oxygen delivery and can harm organs like the lungs (C). Thus C and D are correct to educate the client on CO's effects and risks.
Question 2 of 5
A client is receiving oxygen by nonrebreather mask,but the bag is deflating on inspiration. What action should be taken by the nurse?
Correct Answer: D
Rationale: A nonrebreather mask bag deflating on inspiration indicates insufficient oxygen flow risking CO2 buildup. Increasing liter flow (D) ensures the bag remains inflated delivering adequate oxygen. Turning to the left side (A) is unrelated. Increasing oxygen percentage (B) is not adjustable on standard nonrebreathers. Checking the seal (C) is important but does not address flow issues making D the correct action.
Question 3 of 5
The nurse has completed discharge teaching for a client who will be going home on oxygen therapy. What statement made by the client would indicate that this client needs further instruction?
Correct Answer: A
Rationale: Polyester blankets (A) produce static electricity increasing fire risk with oxygen indicating a need for further instruction. Prohibiting smoking (B) checking grounding (C) and having a fire extinguisher (D) are correct safety measures. Thus A is incorrect as cotton or wool is safer to avoid static sparks in an oxygen-rich environment.
Question 4 of 5
A client who is being mechanically ventilated has copious amounts of secretions ranging from thick and tenacious to frothy. In preparing to suction this client,the nurse should take which action?
Correct Answer: D
Rationale: Hyperventilation (A B) risks pushing secretions deeper worsening obstruction. Instilling saline (C) is not recommended as it can increase infection risk. Increasing oxygen to $100 \%$ for several breaths (D) pre-oxygenates the client preventing hypoxia during suctioning making D the safest and most effective preparation.
Question 5 of 5
A clients blood gas results reveal a low oxygen level. The nurse realizes that which area of the body will respond to this level and influence respirations?
Correct Answer: D
Rationale: Low oxygen (hypoxemia) stimulates carotid bodies (D) located at the carotid artery bifurcation and aortic bodies which signal the respiratory center to increase ventilation. Alveoli (A) trachea (B) and bronchioles (C) do not directly sense oxygen levels making D the correct area influencing respiratory response to hypoxia.
