A patient states she has taken megadoses of vitamin E for 3 months to improve her circulation but thinks she feels somewhat worse. Which action should the nurse take first?
a. Assess the patient for symptoms and signs of toxicity from excess vitamin exposure.
b. Note that research has not shown that vitamin megadoses produce any benefits.
c. Explain to the patient that megadoses may actually be harmful and advise caution.
d. Assess for signs of circulatory impairment to determine whether improvement has occurred.
A
Megadoses of many vitamins, especially when taken over long periods, may produce dangerous side effects or toxicity. The priority for the nurse is to assess for signs of any dangerous consequences of the patient's use of such a regimen. Secondary interventions would include patient education about research findings related to the practice, along with any benefits and undesired effects associated with the practice. The patient should also be assessed for cardiovascular concerns by a health care provider.
