Which of the following interventions would be most appropriate for a nurse to prioritize for a patient with acidosis due to impaired gas exchange?

A.

Administering sodium bicarbonate

B.

Restricting fluid intake

C.

Increasing oxygen supplementation

D.

Administering bronchodilators

Answer and Explanation

The Correct Answer is C

A. Administering sodium bicarbonate: This is used for metabolic acidosis. In respiratory acidosis due to gas exchange issues, the priority is to fix the ventilation problem.

B. Restricting fluid intake: This does not directly address gas exchange or pH balance in an acute respiratory setting.

C. Increasing oxygen supplementation: The primary goal for impaired gas exchange is to improve oxygenation and facilitate the removal of CO2.

D. Administering bronchodilators: While helpful if the cause is asthma or COPD, it is not as broad or immediate a priority for general "impaired gas exchange" as ensuring oxygen delivery.

Correct Answer is D

Explanation

A. Vitamin E capsules: Vitamin E is fat-soluble and absorbed in the small intestine; gastrectomy doesn't specifically target its carrier mechanism.

B. Calcium supplements: While calcium is important, it is not directly dependent on intrinsic factor.

C. Iron tablets: Iron may be needed due to less stomach acid, but B12 is the most critical deficiency specifically related to the loss of intrinsic factor.

D. Vitamin B12 injections: Because the stomach produces intrinsic factor, a partial or total gastrectomy prevents B12 absorption. Since the gut can no longer absorb it, B12 must be given via injection (bypassing the gut).
