Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 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.
Question 2 of 5
The nurse is planning care for a client who was admitted after having a myocardial infarction. Based upon this history,the nurses greatest concern is that this client might develop which health problem?
Correct Answer: C
Rationale: Myocardial infarction (MI) impairs cardiac output reducing oxygen delivery and increasing hypoxemia risk (C) closely linking cardiovascular and respiratory systems. Renal failure (A) gastric ulcers (B) and strokes (D) are possible but secondary concerns making C the greatest immediate respiratory-related concern post-MI.
Question 3 of 5
A nurse is providing discharge instructions to a client who will be using a walker. Which of the following client statements indicates an understanding of the teaching?
Correct Answer: B
Rationale: I will hire someone to trim the tree that hangs low over the stairs of my front porch. Extension cords should be fastened to the floor, frequently used items like an alarm clock, glasses, or disposable tissues should be within reach, throw rugs increase risk and should be removed.

Rationale: Make sure the client wears a mask when outside her room if there is construction in the area. The client's immune system is compromised and needs protection from breathing in pathogens. The room should have at least 12 air exchanges per hour, the room should have positive airflow, and an N95 is for airborne precautions not protective environment.
Question 5 of 5
A nurse is teaching a client and his family how to care for the client's tracheostomy at home. Which of the following instructions should the nurse include in the teaching?
Correct Answer: B
