A medical assistant is administering epinephrine to a patient. The assistant should recognize that the epinephrine will cause which of the following effects in the patient's body?
Blood vessel constriction
Calming effect.
Decrease in blood pressure
Pain control
The Correct Answer is A
A. Blood vessel constriction: Epinephrine is a vasoconstrictor, meaning it causes blood vessels to narrow, which increases blood pressure and is often used in emergency situations like anaphylaxis.
B. Calming effect: Epinephrine does not have a calming effect; it stimulates the fight-or-flight response, increasing heart rate, blood pressure, and alertness.
C. Decrease in blood pressure: Epinephrine increases blood pressure by causing vasoconstriction, not a decrease.
D. Pain control: Epinephrine is not used for pain control; it is used to treat severe allergic reactions, asthma attacks, and cardiac arrest.
