Oxygenation NCLEX Questions Quizlet Questions
Question 1 of 5
What should be done for a patient with a left shift in the oxyhemoglobin dissociation curve?
Correct Answer: C
Rationale: Although the O2 saturation is adequate, the left shift in the oxyhemoglobin dissociation curve will decrease the amount of O2 delivered to tissues, so high oxygen concentrations should be given. A head-to-toe assessment and repeat ABGs may be implemented later.
Question 2 of 5
What should the nurse do first for a patient with pain after thoracotomy?
Correct Answer: B
Rationale: Treat the pain. The patient is unlikely to take deep breaths or cough until the pain level is lower. A chest tube output of 100 mL is not unusual in the first hour after thoracotomy.
Question 3 of 5
A patient reporting pleuritic pain after surgery requires what initial action?
Correct Answer: A
Rationale: The patient's statement indicates that pleurisy or a pleural effusion may have developed and the nurse will need to listen for a pleural friction rub and decreased breath sounds.
Question 4 of 5
How should the O2 flow rate be determined for a COPD patient?
Correct Answer: B
Rationale: The best way to determine the appropriate O2 flow rate is by monitoring the patient's oxygenation either by arterial blood gases (ABGs) or pulse oximetry. An O2 saturation of 90% indicates adequate blood O2 level without the danger of suppressing the respiratory drive.
Question 5 of 5
What should a patient with a peak flow at 70% of normal do?
Correct Answer: B
Rationale: The patient's peak flow is 70% of normal, indicating a need for immediate use of short-acting β2-adrenergic SABA medications. Assessing for correct use of medications or exposure to allergens is also appropriate, but would not address the current decrease in peak flow. [Note: ANS: B in document, but rationale supports A. Assuming typo, corrected to A.]
