A nurse in a mental health clinic is assessing a client who has a history of seeking counseling for relationship problems. The client shows the nurse multiple superficial self-inflicted lacerations on their forearms. The nurse should identify these behaviors as characteristics of which of the following personality disorders?

A. This choice is correct because a child who has autism spectrum disorder often exhibits strict adherence to routines and rituals, and may become distressed or agitated when there are changes or disruptions to their usual patterns.

B. This choice is incorrect because difficulty paying attention to tasks is not a specific manifestation of autism spectrum disorder, but rather a common symptom of attention-deficit/hyperactivity disorder (ADHD). A child who has autism spectrum disorder may have difficulty focusing on tasks that are not of interest to them, but may also show intense concentration on tasks that are of interest to them.

C. This choice is incorrect because disobedience to authority figures is not a specific manifestation of autism spectrum disorder, but rather a common behavior problem in children and adolescents. A child who has autism spectrum disorder may have difficulty understanding social cues and expectations, but may also show compliance and cooperation when given clear instructions and positive reinforcement.

D. This choice is incorrect because excessive anxiety when separated from parents is not a specific manifestation of autism spectrum disorder, but rather a common symptom of separation anxiety disorder. A child who has autism spectrum disorder may have difficulty forming attachments and expressing emotions, but may also show affection and attachment to familiar people.

Choice A reason:

"You should administer the medication at bedtime." This statement is incorrect option. Administering methylphenidate at bedtime is not appropriate because it is a stimulant medication, and taking it in the evening could interfere with the child's ability to fall asleep and disrupt their sleep pattern.

"Your child should avoid foods containing tyramine. “This statement is incorrect option. Tyramine is not a concern with methylphenidate. Tyramine is associated with certain antidepressant medications, such as MAO inhibitors. Methylphenidate is not a MAO inhibitor, so there is no need for the child to avoid tyramine-containing foods.

Option C: "You should administer the medication after breakfast." This is the correct option. Administering methylphenidate after breakfast is a common practice because it allows the child to benefit from the medication during school hours when improved attention and focus are needed the most.

"Your child should avoid excess sodium intake." This statement is an incorrect option. Excess sodium intake is not directly related to methylphenidate use. However, it is generally a good idea for anyone, including children, to have a balanced and healthy diet, which may include monitoring sodium intake. But it is not specifically tied to the administration of methylphenidate.
