Oxygen NCLEX Questions Questions
Question 1 of 5
The following ECG would be classified as:
Correct Answer: B
Rationale: Without the ECG, the answer key indicates 'b'. Atrial fibrillation features irregular R-R intervals and absent P waves.
Question 2 of 5
What information would a home care nurse provide to a patient who is measuring peak expiratory flow rate at home?
Correct Answer: B
Rationale: Peak expiratory flow rate measures forceful exhalation to assess airway obstruction, typically done standing, not lying down.
Question 3 of 5
Patients who have undergone abdominal or chest surgery are at risk for which of the following:
Correct Answer: B
Rationale: Correct Answer: B - Shallow breaths Rationale: 1. Abdominal or chest surgery can cause pain and restrict movement in the chest wall. 2. Pain and restricted movement may lead to shallow breathing. 3. Shallow breathing can result in decreased lung expansion and impaired gas exchange. 4. This can lead to complications such as atelectasis or pneumonia. Summary: A: Excessive coughing - While coughing may be painful post-surgery, it is not a direct risk associated with abdominal or chest surgery. C: Respiratory infection - While surgery can predispose patients to infections, shallow breaths directly impact respiratory function. D: Pneumonitis - While a potential complication, shallow breathing is a more immediate concern post-surgery for gas exchange.
Question 4 of 5
The nurse is careful to monitor a patient's cardiac output because this helps the nurse to determine
Correct Answer: B
Rationale: The correct answer is B: Oxygenation requirements. Monitoring cardiac output helps determine the amount of blood the heart is pumping, which directly affects the delivery of oxygen to tissues. This information is crucial in assessing the patient's oxygenation status and ensuring adequate oxygen supply to meet the body's needs. A: Peripheral extremity circulation - While cardiac output can impact peripheral circulation, it is not the primary reason for monitoring cardiac output. C: Cardiac arrhythmias - Monitoring cardiac output may indirectly help in identifying arrhythmias, but it is not the main purpose of monitoring cardiac output. D: Ventilation status - Cardiac output and ventilation status are related but distinct parameters. Monitoring cardiac output focuses on assessing the heart's ability to pump blood, not the lungs' ability to exchange gases.
Question 5 of 5
A nurse is assessing a client who is receiving oxygen therapy. The nurse should identify which of the following findings can indicate oxygen toxicity?
Correct Answer: B
Rationale: The correct answer is B: Ringing in the ears. Oxygen toxicity can manifest with symptoms such as ringing in the ears, also known as tinnitus. This occurs due to damage to the auditory nerve caused by high levels of oxygen. Hypertension (choice A) is not typically associated with oxygen toxicity. Fever (choice C) is more likely a sign of infection or inflammation, not oxygen toxicity. Dilated pupils (choice D) are not a common indicator of oxygen toxicity. In summary, the correct answer is ringing in the ears as it directly relates to the known effects of oxygen toxicity, while the other choices do not align with typical manifestations of oxygen toxicity.
