Chapter 32: Cholinergic Agonists
The nurse has administrated a drug that will have a therapeutic effect on the client's PNS. The nurse understands the drug will primarily affect what neurotransmitter?
Acetylcholine
A client with Alzheimer disease has been prescribed rivastigmine but has recently begun refusing to swallow pills. Which is the nurse's best action?
Advocate for the prescription of a transdermal patch.
Decreased acetylcholine levels are characteristics of what disorder?
Alzheimer's disease
The nurse is providing information about how to care for clients during a bioterrorism attack. The nurse knows that which drug will be administered in the case of a sarin attack?
Atropine (Atropine is an anticholinergic med. sometimes used to treat some slow HR and decrease saliva production. In case of a nerve gas attack, atropine is the antidote. It is typically given by IV of injection into the muscle.)
A client is experiencing urinary retention after surgery. The nurse would anticipate administering what medication?
Bethanechol
The PCP is preparing to write a prescription for a client diagnosed with urinary retention. Which medication does the nurse expect to be prescribed?
Bethanechol
A nurse is conducting a medication resolution of a new resident of a care facility and notes that the woman has been taking neostigmine. The nurse should recognize that the woman may have a history of what health problem?
Myasthenia gravis
After teaching a group of students about indirect acting cholinergic agonists used to treat myasthenia gravis, the instructor determines that the teaching was effective when the students identify which agent?
Neostigmine
A military nurse is part of a team reviewing the appropriate response to chemical weapon attacks, including sarin, tabun, and soman. When reviewing the physiology of a response to such drugs, the nurse should identify what goal of treatment?
Restore anticholinesterase function (These drugs are irreversible anticholinesterase agents. The goal of treatment, such as atropine administration, is to restore normal function of anticholinesterase and rid synapses of excessive acetylcholine. Treatment will not achieve any of the other stated goals.)
The nurse is caring for a client who is receiving neostigmine for the treat of myasthenia gravis. The nurse is aware that a potential complication of the treatment is cholinergic crisis, which is characterized by which event?
excessive stimulation of the parasympathetic NS (cholinergic crisis is characterized by excessive stimulation of the PNS. if symptoms are not treated early, hypotension and respiratory failure may occur.
