Chapter 32- Cholinergic Agonists, Exams of Nursing

Utah Valley University (UVU)Nursing
Prof. Weslie E. Sheldon

Your patient has had cevimeline (Evoxac) prescribed. What would be an appropriate dosing schedule for a patient taking cevimeline (Evoxac)? Once a day Twice a day Three times a day Every four hours A student asks the pharmacology instructor to describe the function of a cholinergic agonist. What would the instructor reply? Cholinergic agonists increase the activity of dopamine receptor sites throughout the brain and spinal cord. Cholinergic agonists decrease the activity of GABA receptor sites throughout the body. Cholinergic agonists increase the activity of acetylcholine receptor sites throughout the body. Cholinergic agonists decrease the activity of norepinephrine receptor sites throughout the brain and spinal cord.
