An outpatient substance abuse clinic provides vouchers to clients who have a negative urine drug screen. This is an example of which of the following?
Contingency management
Operant conditioning
Cognitive learning
Stimulus discrimination
The Correct Answer is A
Choice A reason: Contingency management is a behavioral intervention that uses tangible rewards to reinforce positive behaviors, such as abstinence. Providing vouchers for clean drug screens is a classic example of this approach.
Choice B reason: Operant conditioning is the broader framework under which contingency management falls. While technically correct, it is less specific than contingency management in this context.
Choice C reason: Cognitive learning involves acquiring knowledge and understanding through thought, experience, and the senses. It does not involve external rewards for behavior.
Choice D reason: Stimulus discrimination refers to the ability to distinguish between different stimuli and respond appropriately. It is not relevant to the reward-based system described.

Correct Answer is B
Explanation
Choice A reason: Schizoid personality disorder is characterized by detachment from social relationships and a limited range of emotional expression. While the client shows social withdrawal and constricted affect, the presence of magical thinking and unusual beliefs (ESP and UFO experiences) is not typical of schizoid personality disorder.
Choice B reason: Schizotypal personality disorder includes social anxiety, eccentric behavior, odd beliefs or magical thinking, and peculiar speech or appearance. The client’s lifelong social anxiety, mismatched clothing, constricted affect, and belief in ESP following a UFO sighting are hallmark features of schizotypal personality disorder.
Choice C reason: Paranoid personality disorder involves pervasive distrust and suspicion of others. Although the client shows some suspiciousness, the presence of magical thinking and eccentric behavior is more consistent with schizotypal personality disorder.
Choice D reason: Antisocial personality disorder is marked by disregard for the rights of others, deceitfulness, impulsivity, and lack of remorse. There is no evidence of these traits in the scenario, making this diagnosis inappropriate.
Correct Answer is B
Explanation
Choice A reason: Neural tube defects are commonly associated with folate deficiency and medications like valproic acid or carbamazepine, not lithium.
Choice B reason: Ebstein's anomaly is a congenital heart defect involving the tricuspid valve and is the most well-documented teratogenic risk associated with lithium exposure during the first trimester. It is rare but serious, making this the correct answer.
Choice C reason: Cleft palate is associated with various teratogens, including phenytoin and alcohol, but not typically with lithium.
Choice D reason: Floppy baby syndrome refers to hypotonia in infants and is most commonly linked to maternal benzodiazepine use, not lithium.
