Final answer:
The nurse needs to monitor for cutaneous flushing as an adverse effect when administering niacin.
Step-by-step explanation:
When administering niacin, the nurse needs to monitor for cutaneous flushing as an adverse effect. Niacin, also known as vitamin B3, can cause the skin to become red and warm, resembling a sunburn, due to its vasodilatory effects. This occurs because niacin causes blood vessels to widen and increase blood flow to the skin.
Niacin, also known as vitamin B3, is a water-soluble vitamin that plays a crucial role in various physiological processes in the body. It is one of the eight B vitamins and is essential for maintaining overall health. Niacin is involved in the metabolism of carbohydrates, fats, and proteins, and it also plays a role in DNA repair and cell signaling.
