Oxygenation NCLEX Questions Questions
Question 1 of 5
A nurse is assessing a patient with suspected carbon monoxide poisoning. What is the priority finding?
Correct Answer: A
Rationale: Carbon monoxide poisoning causes cherry-red lips due to carboxyhemoglobin formation, impairing oxygen delivery. This is a specific, priority sign over fever, tachycardia, or hypotension.
Question 2 of 5
A patient with a respiratory rate of 30 breaths per minute is experiencing what?
Correct Answer: B
Rationale: A rate of 30 breaths per minute is hyperventilation (normal is 12-20), increasing oxygen intake, unlike hypoventilation, normal breathing, or apnea.
Question 3 of 5
A nurse is reinforcing discharge teaching with a client following an episode of status asthmaticus. The client has a prescription for two inhalations from an albuterol metered-dose inhaler. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: A
Rationale: Holding the breath for at least 10 seconds after inhaling the medication allows the medication to settle in the lungs and increases its effectiveness. This ensures maximum delivery of the drug to the respiratory tract.
Question 4 of 5
A patient is admitted to a respiratory unit with a diagnosis of bacterial pneumonia. Findings include a fever and a weak, congested-sounding cough and moist crackles throughout the lung fields. How should the nurse prioritize care?
Correct Answer: B
Rationale: The inability to clear the airway is a critical issue. This patient has a weak, congested-sounding cough and moist crackles, indicating that secretions are present and not being effectively cleared. This can lead to worsening infection, decreased oxygenation, and further respiratory complications. Clearing the airway is a top priority to ensure the patient can breathe properly and prevent further deterioration.
Question 5 of 5
A client is receiving oxygen therapy via a nasal cannula. What is the appropriate flow rate for this client?
Correct Answer: B
Rationale: The appropriate flow rate for oxygen therapy via a nasal cannula typically ranges from 1-6 liters per minute, with 4-6 liters per minute being a common range to achieve adequate oxygenation.
