Questions: A nurse should assess a client who has megacolobacteria for indications of which of the following vitamin deficiencies? Vitamin D Vitamin B12 Vitamin K Vitamin C

The answer is the second one: Vitamin B12.

Explanation for each option:

• Vitamin D: This vitamin is primarily absorbed in the small intestine and is not typically associated with bacterial overgrowth in the colon. Deficiency is more related to lack of sunlight exposure or dietary intake.

• Vitamin B12: Megacolobacteria, or bacterial overgrowth in the colon, can lead to Vitamin B12 deficiency. This is because certain bacteria can consume Vitamin B12, reducing its availability for absorption in the ileum, where it is normally absorbed.

• Vitamin K: While some gut bacteria produce Vitamin K, a deficiency is less commonly associated with bacterial overgrowth. Vitamin K deficiency is more often related to issues with fat absorption or liver disease.

• Vitamin C: This vitamin is absorbed in the small intestine and is not typically affected by bacterial overgrowth in the colon. Deficiency is more related to dietary intake.

In summary, a nurse should assess a client with megacolobacteria for indications of Vitamin B12 deficiency due to the potential for bacterial consumption of this vitamin, leading to reduced absorption.
