A patient is admitted to the emergency department for a severe migraine headache
The patient tells the nurse that she has used Cafergot (ergotamine tartrate and caffeine) for frequent migraine headaches over the past 6 months and has been experiencing numbness and tingling in the fingers and toes. The nurse should further assess the patient for which of the following signs and symptoms? (Select all that apply.) a. Diminished peripheral pulses
b. Muscle aches
c. Pallor of the extremities
d. Nausea
e. Vomiting
A, B, C
Chronic use of Cafergot can lead to overdose, which should be suspected in this case because the patient has had frequent episodes of migraines and subsequent numbness and tingling in the fin-gers and toes. Overdose can cause ischemia secondary to constriction of peripheral arteries and arterioles, which can cause the extremities to become cold, pale, and numb. Muscle pain develops, and gangrene eventually may result.
Nausea and vomiting are side effects, not the effects of a possible overdose of Cafergot.
