Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
Safety is necessary when oxygenating a human.
Correct Answer: A
Rationale: Safety is indeed necessary when oxygenating a human because oxygen is highly flammable, and improper handling can lead to serious risks such as fires or explosions. Proper precautions ensure the safety of both the patient and the caregiver.
Question 2 of 5
A surgical incision into the trachea to aerate the lungs is:
Correct Answer: A
Rationale: The correct answer is A: a tracheostomy. This procedure involves making an incision into the trachea to create a direct airway access for breathing. Tracheostomy is used in cases of upper airway obstruction or long-term mechanical ventilation. Endotracheal suctioning (choice B) is a procedure to remove secretions from the trachea using a catheter. Bronchial suctioning (choice C) is similar but targets secretions in the bronchi, not the trachea. Choice D, a cannula, is a hollow tube used to deliver fluids or medication, not for aerating the lungs directly. Tracheostomy is the correct choice as it specifically involves creating an opening in the trachea for ventilation.
Question 3 of 5
When caring for a patient with atrial fibrillation, the nurse is most concerned with which vital sign?
Correct Answer: A
Rationale: The correct answer is A: Heart rate. In atrial fibrillation, the heart rate is irregular and can be rapid, leading to ineffective pumping of blood. Monitoring heart rate is crucial to assess the patient's cardiac function and response to treatment. Pain (B) is not typically a primary concern in atrial fibrillation. Oxygen saturation (C) is important but not as directly related to the condition. Blood pressure (D) is important but may not be as immediately affected by atrial fibrillation as heart rate.
Question 4 of 5
A nurse is discussing ventilation and perfusion with a newly licensed nurse. The nurse should include in the discussion that the exchange of oxygen and carbon dioxide occurs at which of the following locations?
Correct Answer: B
Rationale: The correct answer is B: Alveoli. Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place during respiration. Oxygen from the air we breathe diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. The trachea (A) is a passageway for air, the diaphragm (C) is a muscle involved in breathing, and the bronchial tubes (D) are airways leading to the lungs, but the actual gas exchange occurs in the alveoli.
Question 5 of 5
A nurse is caring for a client receiving supplemental oxygen. The nurse notes that the client's oxygen saturation is 88%. Which of the following actions should the nurse take first?
Correct Answer: B
Rationale: The correct answer is B: Assess the client for signs of respiratory distress. This is the first action the nurse should take because an oxygen saturation of 88% indicates hypoxemia, which can lead to respiratory distress. By assessing the client, the nurse can determine if the client is in immediate need of intervention. Increasing oxygen flow rate (A) may be necessary, but assessing the client's condition comes first. Notifying the provider (C) can be done after assessing the client's immediate needs. Administering a bronchodilator (D) may be indicated if respiratory distress is due to bronchoconstriction, but assessing the client's overall condition is the priority.
