A patient with chronic atrophic gastritis was prescribed monthly Cobalamin (B12) injections The determines that teaching regarding the injections has been eﬀective when the patient States:

These injections will increase the hydrochloric acid in my stomach:

The cobalamin injections need to be taken until my inﬂamed stomach heals.

The cobalamin injections will prevent me from becoming anemic.

These injections will decrease my risk for developing Stomach cancer.

Answer and Explanation

The Correct Answer is C

The correct answer is choice c. The cobalamin injections will prevent me from becoming anemic.

Choice A rationale:

Cobalamin (B12) injections do not increase hydrochloric acid production in the stomach. Chronic atrophic gastritis often leads to decreased production of hydrochloric acid due to the loss of parietal cells, but B12 injections do not reverse this condition.

Choice B rationale:

The need for cobalamin injections is typically lifelong in patients with chronic atrophic gastritis because the condition leads to a permanent loss of intrinsic factor, which is necessary for B12 absorption. The injections are not just until the stomach heals.

Choice C rationale:

Chronic atrophic gastritis can lead to vitamin B12 deficiency due to the loss of intrinsic factor, which is essential for B12 absorption. This deficiency can cause pernicious anemia, and B12 injections are necessary to prevent this condition.

Choice D rationale:

While chronic atrophic gastritis does increase the risk of stomach cancer, B12 injections are not specifically aimed at reducing this risk. The primary purpose of B12 injections is to prevent anemia.

Correct Answer is D

Explanation

Coﬀee-ground material in the NG suction indicates that there is active bleeding in the upper gastrointestinal tract, which could be a life-threatening situation. This requires immediate medical attention and intervention to control the bleeding and stabilize the patient.

Options A, B, and C are also important assessment data, but they are not as urgent as option D in this scenario.

A. Respiratory alkalosis B. Respiratory acidosis C. Metabolic alkalosis D. Metabolic acidosis

Correct Answer is A

Explanation

Based on the given arterial blood gas results, the patient's pH is elevated, indicating alkalosis. The PaCO2 level is decreased, which suggests respiratory compensation. The bicarbonate (HCO3-) level is within the normal range. Therefore, the interpretation of the arterial blood gas results is respiratory alkalosis.
