The nurse provides care to a patient admitted with a respiratory disorder. Which laboratory finding is most concerning?
Oxygen saturation 96%
Blood pH 7.32
Hemoglobin level 12 mg/dL
PaO2 80 mm Hg
The Correct Answer is B
A. Oxygen saturation 96%. This is a normal oxygen saturation level, so it is not a concern.
B. Blood pH 7.32. A pH below 7.35 indicates acidosis, which is concerning in a patient with a respiratory disorder, as it may indicate respiratory failure.
C. Hemoglobin level 12 mg/dL. This is a normal hemoglobin level for most adults and does not indicate a critical problem.
D. PaO2 80 mm Hg. While slightly lower than the normal range (normal is 80–100 mm Hg), this is not the most concerning finding.

Correct Answer is D
Explanation
A. Ensure an NPO status is maintained for the length of the prescribed treatment: While some ventilated patients are NPO, others receive enteral feeding. NPO status alone does not prevent aspiration.
B. Perform chest physiotherapy as prescribed by the practitioner: Chest physiotherapy helps clear secretions but does not directly reduce aspiration risk.
C. Limit each suctioning event to no more than 10 seconds: While limiting suction time is important to avoid hypoxia, it does not directly prevent aspiration.
D. Elevate the head of the bed between 30 to 45 degrees: Keeping the head of the bed elevated reduces the risk of aspiration, partic
Correct Answer is B
Explanation
A. Nonrebreather mask. A nonrebreather mask delivers high concentrations of oxygen but requires a tight seal around the face, which is not suitable for patients with facial trauma.
B. Face tent. A face tent is the best option for a patient with facial trauma as it provides high-flow oxygen without requiring direct contact with the face, preventing pressure on injured areas.
C. Nasal cannula. A nasal cannula provides low-flow oxygen and may be ineffective for a patient requiring high-flow therapy.
D. Venturi mask. A Venturi mask delivers precise oxygen concentrations but still requires a snug fit on the face, which may not be comfortable or feasible for a patient with facial trauma.
