The nurse provides care to a patient who is recovering from facial trauma who requires high-flow oxygen therapy. Which method of oxygen delivery does the nurse recognize as best for this patient?
Nonrebreather mask
Face tent
Nasal cannula
Venturi mask
The Correct Answer is B
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.

A. Numbness of fingers. Numbness or tingling (paresthesia) is more common in respiratory alkalosis due to low CO₂ levels causing calcium binding changes.
B. Dry skin. Respiratory acidosis does not typically cause dry skin; rather, it may cause cyanosis or flushed skin due to CO₂ retention.
C. Abdominal pain. Abdominal pain is more commonly seen in metabolic acidosis, not respiratory acidosis.
