Correct Answer: C

Rationale: The most appropriate goal of cognitive-behavioral therapy (CBT) in treating generalized anxiety disorder (GAD) is to change the patient's negative thought patterns. This therapy focuses on identifying and modifying distorted thinking patterns that contribute to anxiety. Exploring childhood experiences (Choice A) may be part of therapy, but the primary focus is on present thoughts and behaviors. While medication (Choice B) can help manage symptoms, CBT aims to address the root cause through cognitive restructuring. Improving social skills (Choice D) is not the primary goal of CBT for GAD, although it may be a secondary benefit as confidence improves with reduced anxiety.

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.

Correct Answer: B

Rationale: During a panic attack, the priority intervention for the nurse is to provide reassurance and stay with the patient. This action helps reduce fear and provides a sense of safety, which can aid in calming the patient and preventing further escalation of the panic attack. Encouraging the patient to verbalize their feelings (Choice A) may be beneficial after the acute phase of the panic attack. Leaving the patient alone (Choice C) may increase feelings of abandonment and escalate the panic attack. Distracting the patient with a task (Choice D) is not recommended during a panic attack as it may divert attention but not address the underlying anxiety and fear.

Correct Answer: D

Rationale: Venlafaxine is classified as a serotonin-norepinephrine reuptake inhibitor (SNRI). SNRIs work by increasing the levels of both serotonin and norepinephrine in the brain, which helps alleviate symptoms of depression. This mechanism of action distinguishes SNRIs from other classes of antidepressants like SSRIs, TCAs, and MAOIs, making venlafaxine an effective choice for patients with major depressive disorder. Therefore, the correct answer is D. Choice A, SSRIs, primarily target serotonin reuptake only. Choice B, TCAs, work by inhibiting the reuptake of norepinephrine and serotonin, but they are not as selective as SNRIs. Choice C, MAOIs, inhibit the enzyme monoamine oxidase, leading to increased levels of various neurotransmitters, including serotonin and norepinephrine, but they are typically used as second- or third-line agents due to dietary restrictions and potential side effects.

Correct Answer: A

Rationale: Cognitive-behavioral therapy (CBT) is widely recognized as the most effective treatment for phobias. CBT helps individuals identify and change negative thought patterns and behaviors associated with their phobias, leading to long-lasting improvement and symptom reduction. Unlike psychoanalysis, which focuses on exploring unconscious conflicts, CBT provides practical strategies to address phobias directly. Medication management may be used in conjunction with therapy but is not typically considered a standalone treatment for phobias. Group therapy can be beneficial for some individuals, but CBT is specifically tailored to target and alleviate phobia symptoms effectively.
