A
Increased heart rate
B
Decreased blood glucose levels
C
Dilation of airways
D
Increased blood pressure
Verified step by step guidance1
Understand the role of epinephrine: Epinephrine, also known as adrenaline, is a hormone and neurotransmitter that plays a key role in the body's fight-or-flight response.
Identify the common effects of epinephrine: Typically, epinephrine increases heart rate, dilates airways, and increases blood pressure to prepare the body for rapid action.
Consider the effect on blood glucose levels: Epinephrine generally increases blood glucose levels by stimulating glycogenolysis, which is the breakdown of glycogen to glucose in the liver.
Analyze the options given: Compare each option with the known effects of epinephrine. Increased heart rate, dilation of airways, and increased blood pressure are consistent with epinephrine's effects.
Determine the incorrect statement: Since epinephrine increases blood glucose levels, the statement 'Decreased blood glucose levels' is not an effect of epinephrine.
