The patient is diagnosed with myasthenia gravis, a condition in which antibodies block, alter, or destroy the receptors for acetylcholine. What symptom would the nurse expect this patient to display?
A) Muscle dysfunction
B) Seizures
C) Uncoordinated movements
D) Sleep all the time
A
Feedback:
Acetylcholine communicates between nerves and muscles so inability of this neurotransmitter to function properly, whether blocking, altering, or destroying the receptors, would result in muscle dysfunction. Inadequate gamma-aminobutyric acid would result in seizures. Inadequate dopamine would result tin uncoordinated movements. Serotonin is important in arousal and sleep.
