A client has been taking large amounts of over-the-counter niacin to lower cholesterol. When assessing the client, which of the following symptoms would be of most concern to the nurse?
1. Heartburn and abdominal discomfort
2. Pale skin
3. Episodic diarrhea
4. A sense of spreading warmth and flushing
1
Rationale: Niacin, taken in large doses, can cause GI distress and aggravate peptic ulcer disease, so the nurse should be concerned about heartburn or abdominal discomfort. Flushing and warmth are a normal side effect of niacin consumption. Pale skin is not associated with niacin consumption. Diarrhea might occur with a niacin deficiency.
