A Hispanic woman comes to the clinic with complaints of occasional headaches and fatigue. Upon assessment, the patient's vital signs are BP 163/97, P 82/minute, T 97.8° F, R 18/minute
Her height is 5' 2", and her weight is 165 pounds. She is diagnosed with hypertension. What class of medication would the nurse anticipate the prescriber will order for this patient?
a. Sympathetic antagonist
b. Parasympathetic antagonist
c. Sympathomimetic agent
d. Sympathetic agonist
ANS: A
A sympathetic antagonist blocks the actions of the sympathetic nervous system, causing blood pressure to come down in a patient with hypertension.
A parasympathetic antagonist has an opposing effect, which causes the blood pressure to rise; this is contraindicated in a patient with hypertension.
A sympathomimetic agent mimics the effects of sympathetic response, causing an increase in blood pressure; this is contraindicated in a patient with hypertension.
A sympathetic agonist also causes a sympathetic response and increases blood pressure; this is contraindicated in a patient with hypertension.
