NCLEX Style Questions on Oxygenation Questions
Question 1 of 5
The nurse is providing care to a client with arterial blood gas analysis as follows: PaO2 of 82, PaCO2 of 49, HCO3 of 26, and pH of 7.31. Which assessment by the nurse is correct?
Correct Answer: A
Rationale: Both the pH (7.31) and the PaCO2 (49) represent acidosis. The PaO2 of 82 is on the low end of normal and the bicarbonate level (26) is normal, indicating respiratory acidosis (A) rather than metabolic acidosis.
Question 2 of 5
The nurse is providing teaching to parents about respiratory syncytial virus (RSV). Which statement by the nurse is correct?
Correct Answer: D
Rationale: RSV is a common cause of bronchiolitis in infants (D), especially in daycare settings, and is viral, not preventable with antibiotics.
Question 3 of 5
When caring for a patient prescribed oxygen per nasal cannula, which of the following actions is best directed toward maintaining appropriate oxygen delivery?
Correct Answer: D
Rationale: Proper placement of the cannula tips ensures oxygen is delivered effectively to the patient's respiratory system, which is the primary goal of oxygen therapy.
Question 4 of 5

Correct Answer: D
Rationale: Oxygen makes up 21% of the air in the atmosphere, as matched in the document.
Question 5 of 5
Which assessments and interventions should the nurse consider when performing tracheal suctioning? Select one that doesn't apply.
Correct Answer: C
Rationale: Close assessment of the patient before, during, and after the procedure is necessary to limit negative effects. Risks include hypoxia, infection, tracheal tissue damage, dysrhythmias, and atelectasis. The nurse should hyperoxygenate the patient before and after suctioning and limit the application of suction to 10 to 20 seconds. The nurse should also take the patient's pulse frequently to detect potential effects of hypoxia and stimulation of the vagus nerve. Using an appropriate suction pressure (80 to 150 mm Hg) will help prevent atelectasis related to the use of high negative pressure. (Note: E is 'Use an appropriate suction pressure (80 to 150 mm Hg)' from the provided options.)
