ATI Mental Health Practice A

Correct Answer: C

Rationale: Drowsiness is a common side effect of benzodiazepines prescribed for anxiety. Benzodiazepines work by depressing the central nervous system, which can lead to drowsiness as a side effect. This sedative effect is often desired in the treatment of anxiety disorders, but individuals should be cautious when engaging in activities that require alertness, such as driving, while taking these medications. Insomnia, weight gain, and increased appetite are not typically associated with benzodiazepines; instead, drowsiness and sedation are more common side effects.

Correct Answer: D

Rationale: Escitalopram, an SSRI used in treating generalized anxiety disorder, typically takes 6-8 weeks to achieve its full therapeutic effect. While some improvement may be noticed earlier, the maximum benefit is usually experienced after this timeframe. Options A, B, and C are incorrect because they underestimate the time required for escitalopram to reach its full effectiveness. Educating patients about the realistic timeline for medication effectiveness is crucial in managing expectations and ensuring adherence to the prescribed treatment.

Correct Answer: A

Rationale: Encouraging deep, slow breathing is the most appropriate intervention for a patient experiencing a panic attack. This technique can help the patient regulate their breathing, reduce hyperventilation, and promote relaxation, which are essential in managing the symptoms of a panic attack. Choice B, encouraging the patient to talk about their feelings, may not be effective during an acute panic attack as the focus should be on calming the patient down. Choice C, leaving the patient alone, can lead to increased feelings of fear and isolation during a panic attack. Choice D, engaging the patient in physical activity, may exacerbate symptoms as it can increase the feeling of being out of control.

Correct Answer: C

Rationale: The correct answer is C, 'Sexual dysfunction.' Paroxetine, an SSRI commonly prescribed for OCD, can lead to sexual dysfunction as a side effect. Patients should be educated about this potential adverse effect to ensure they are aware and can seek appropriate management if needed. Choices A, B, and D are incorrect because insomnia, weight loss, and hypertension are not typically associated with paroxetine use as common side effects in patients with OCD.

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.
