Impaired venous return
C)
Decreased intravascular volume
D)
Compression of blood vessels

Question 2

A 20-year-old female has been brought to the emergency department from a rave party where she collapsed on the dance floor. Her accompanying friends acknowledge that the woman took ecstasy early in the evening.

Her heart rate is regular at 89 beats/minute and temperature 39.8 C (103.6 F) orally. The emergency team would recognize that which of the following phenomena, related to the drug, is a likely contributor to the woman's status?
A)
Increased peripheral vasoconstriction
B)
The direct pyrogenic effect of ecstasy
C)
The initiation of an inappropriate immune response
D)

Answer to Question 1

Ans:
A

Feedback:

Venous stasis, decreased intravascular volume contributing to a hypercoagulable state, and pressure from the mattress that compresses the veins are elements of Virchow risk triad for thromboembolic disease. Increased heart rate is less likely to contribute to DVT.

Answer to Question 2

Ans:
A

Feedback:

Amphetamines such as ecstasy can induce hyperthermia by increasing peripheral vasoconstriction. They are not associated with direct hypothalamic effect, pyrogenic effect, or an immune response.
