Final answer:
An epinephrine infusion at 0.02 mcg/kg/min is most likely to increase heart rate due to its action on the beta-1 adrenergic receptors. Epinephrine also increases blood pressure and is used as a primary treatment for anaphylactic shock. Acetylcholine, on the other hand, increases digestion, which corrects the incorrect statement provided.
Step-by-step explanation:
An infusion of epinephrine (Epi) at 0.02 mcg/kg/min is most likely to have the following effect: increased heart rate. Epinephrine, also known as adrenaline, is a hormone and a medication that is involved in regulating visceral functions (i.e., those of the inner organs). Epinephrine increases blood pressure and the heart rate due to its action on the beta-1 adrenergic receptors in the heart. Conversely, beta-blockers can be used to inhibit the effects of adrenaline and can lead to an inhibitory effect on heart rate and blood pressure.
The incorrect pairing from the provided information would be a statement (c): acetylcholine decreases digestion, whereas acetylcholine actually increases digestion by stimulating the muscles of the gastrointestinal tract and increasing the secretion of digestive enzymes. As for the drug used to counteract the effects of anaphylactic shock, the answer is (a) epinephrine. Epinephrine is the primary treatment for anaphylaxis with its vasoconstrictive effects that also help to alleviate symptoms.
Overall, epinephrine is known for its role in the body's fight-or-flight response, where it increases heart rate, breathing rate, muscle contractions, blood pressure, and blood glucose levels, preparing the body to respond to a perceived threat.
