The nurse is caring for a client who blinks when the nurse asks a question and coughs when the nurse looks at him. Which condition does the nurse suspect?

Choice A reason: Conduct disorder involves persistent patterns of violating societal norms and the rights of others. Involuntary motor or vocal tics are not characteristic of conduct disorder. Choice B reason: Tourette’s disorder is characterized by multiple motor tics and at least one vocal tic. Blinking and coughing are examples of involuntary motor and vocal tics, making this the most appropriate diagnosis. Choice C reason: Oppositional defiant disorder involves defiance, irritability, and argumentative behavior toward authority figures. It does not include involuntary tics. Choice D reason: Autism spectrum disorder involves social communication deficits and restricted, repetitive behaviors. While stereotyped movements may occur, involuntary tics such as blinking and coughing are not typical features.
