Oxygenation Nursing Practice Questions Questions
Question 1 of 5
Which of the following lung volumes or capacities is calculated by adding the tidal volume, inspiratory reserve volume, and expiratory reserve volume?
Correct Answer: C
Rationale: Vital capacity (VC) = Vt + IRV + ERV, representing the maximum volume of air that can be exhaled after maximum inhalation.
Question 2 of 5
An emergency room nurse is auscultating the chest of a child who is having an asthmatic attack. Auscultation reveals the presence of wheezes. During what part of respirations do wheezes occur?
Correct Answer: A
Rationale: Wheezes in asthma occur during both inspiration and expiration due to narrowed airways.
Question 3 of 5
The nurse knows that a myocardial infarction is an occlusion of what blood vessel?
Correct Answer: C
Rationale: The correct answer is C: Coronary artery. A myocardial infarction is caused by a blockage in the coronary arteries, leading to inadequate blood supply to the heart muscle. This can result in damage to the heart tissue. The pulmonary artery (A) carries deoxygenated blood from the heart to the lungs, not to the heart muscle. The ascending aorta (B) is the large artery that carries oxygenated blood away from the heart, not directly supplying the heart muscle. The carotid artery (D) supplies blood to the brain, not the heart muscle.
Question 4 of 5
While the nurse is changing the ties on a tracheostomy collar, the patient coughs, dislodging
Correct Answer: A
Rationale: The correct answer is A: What is the nurse's first nursing action? In this scenario, the nurse's first priority is to assess the patient's airway and breathing. By asking "What is the nurse's first nursing action?" the nurse can quickly assess the situation and determine if further intervention is needed. Choice B (Press the emergency response button) is incorrect as it does not address the immediate need to assess the patient's airway. Choice C (Place the patient on a face mask delivering 100% oxygen) is incorrect as it assumes the patient's airway is compromised and does not address the need to assess first. Choice D (Insert a spare tracheostomy without the obturator) is also incorrect as this action should only be taken if the tracheostomy tube is completely dislodged and the nurse has assessed that it is necessary.
Question 5 of 5
A nurse is caring for a client who has a chest tube. Which of the following findings should the nurse report to the provider?
Correct Answer: B
Rationale: The correct answer is B: Drainage of 80 mL of fluid in the past hour. This finding indicates excessive drainage, which could be a sign of hemorrhage or other complications requiring immediate medical attention. A: Intermittent bubbling in the water seal chamber is expected and indicates proper functioning of the chest tube system. C: Tidaling in the water seal chamber with respiration is a normal finding that indicates the system is functioning correctly. D: Fluctuation in the drainage tubing with breathing is also a normal finding that shows the chest tube is working properly. In summary, choice B is the correct answer as it signals a potentially serious issue, while the other choices are normal findings associated with a functioning chest tube system.
