A client is experiencing bladder hyperactivity. The nurse should be prepared to educate the client about which of the following medications that may be injected to help decrease the bladder hyperactivity?

Question

A) Capsaicin, a specific C-fiber afferent neurotoxin
B) Botulinum toxin type A
C) Oxybutynin, an antimuscarinic agent
D) Urecholine, a cholinergic agonist

Answer 1

Ans: A
Feedback:
Intravesical injection of medications, such as capsaicin and resiniferatoxin, that are specific C-fiber afferent neurotoxins may be used to decrease bladder hyperactivity. Botulinum toxin type A is used to produce paralysis of striated muscles of the external sphincter. Oxybutynin, an antimuscarinic agent, will decrease detrusor muscle tone. Urecholine, a cholinergic agonist, stimulates parasympathetic receptors to increase bladder tone.
