A patient who has a history of hypertension presents to the emergency department and complains of slight chest pain, rating the pain as a 4 on a scale of 0 to 10;
the blood pressure is 149/92, pulse 138/minute, respirations 24/minute, and temperature 99.0° F. The nurse should anticipate that the prescriber would order what class of medication specifically to lower the heart rate?
a. Sympathomimetic agent
b. Parasympathetic antagonist
c. Parasympathetic inhibitor
d. Sympathetic antagonist
ANS: D
A sympathetic antagonist would block the effects of the sympathetic nervous system and, as a result, lower the heart rate.
A sympathomimetic results in an increase in the heart rate, because it produces a mimicking of the sympathetic nervous system.
A parasympathetic antagonist blocks the effects of the parasympathetic nervous system, thus increasing the heart rate.
A parasympathetic inhibitor would also block the effects of the parasympathetic nervous system, thus increasing the heart rate.
