Which of the following medications is commonly used to treat attention-deficit/hyperactivity disorder (ADHD)?

Correct Answer: C

Rationale: Methylphenidate is a central nervous system stimulant commonly used in the treatment of ADHD. It helps improve focus, attention, and impulse control in individuals with ADHD. Haloperidol and clozapine are antipsychotic medications typically used for other conditions such as schizophrenia, while fluoxetine is a selective serotonin reuptake inhibitor commonly used to treat depression and anxiety disorders. Therefore, the correct answer is Methylphenidate (Choice C).

Correct Answer: A

Rationale: Memory loss, especially short-term memory loss, is a common side effect associated with electroconvulsive therapy (ECT). During ECT treatment, the electrical currents passed through the brain can disrupt short-term memory formation. This side effect is usually temporary, but patients should be closely monitored for any changes in memory function during and after the treatment. Choices B, C, and D are incorrect because they are not commonly associated with ECT. Hypertension, weight gain, and hyperglycemia are not typically observed as side effects of ECT.

Correct Answer: A

Rationale: Cognitive processing therapy is a specialized form of cognitive-behavioral therapy that has been shown to be highly effective in treating posttraumatic stress disorder (PTSD). This therapy focuses on helping individuals process and make sense of their traumatic experiences, leading to symptom reduction and improved coping mechanisms. Psychoanalysis, medication management, and group therapy can be beneficial in some cases, but cognitive processing therapy is specifically tailored for addressing the symptoms and underlying causes of PTSD. Psychoanalysis may not be as effective for PTSD due to its focus on unconscious conflicts rather than trauma processing. Medication management can be useful as an adjunct to therapy but does not address the core issues of PTSD. Group therapy can provide support but may not offer the individualized approach that cognitive processing therapy provides.

Correct Answer: B

Rationale: During a manic episode in bipolar disorder, individuals may experience heightened energy levels, impulsivity, and decreased need for sleep. Providing a structured and low-stimulus environment is crucial in managing manic episodes. This intervention helps reduce overstimulation and provides a calm and predictable setting, which can be beneficial in helping the patient regain control and stability. Group activities and high-energy physical activities may exacerbate the symptoms of mania by increasing stimulation and excitement. Allowing the patient to set their schedule may not provide the necessary structure needed during a manic episode, hence making it less appropriate.

Correct Answer: B

Rationale: Flat affect and social withdrawal are characteristic of negative symptoms in schizophrenia. Negative symptoms involve disruptions to normal emotions and behaviors, such as reduced emotional expression (flat affect) and social withdrawal. These symptoms reflect a decrease or absence of normal functions. Positive symptoms, on the other hand, involve the presence of abnormal behaviors or experiences, such as hallucinations and delusions, which are added to a person's experiences. Cognitive symptoms relate to difficulties with thinking, memory, and processing information, impacting cognition. Mood symptoms involve disturbances in mood regulation, which is distinct from the flat affect seen in negative symptoms.
