ATI Mental Health Practice A

Correct Answer: C

Rationale: The correct answer is C: Dry mouth. Dry mouth is a common side effect associated with tricyclic antidepressants (TCAs). TCAs block acetylcholine receptors, leading to anticholinergic effects such as dry mouth, constipation, blurred vision, and urinary retention. It is important for the nurse to educate the patient about this side effect to promote awareness and provide appropriate management strategies, such as maintaining good oral hygiene and staying hydrated. Choice A, hypertension, is not a common side effect of TCAs. Choice B, diarrhea, is not a typical side effect of TCAs; in fact, TCAs are more likely to cause constipation. Choice D, weight loss, is less common with TCAs as they are more likely to cause weight gain.

Correct Answer: C

Rationale: Paroxetine is a selective serotonin reuptake inhibitor (SSRI) commonly prescribed for obsessive-compulsive disorder due to its efficacy in managing OCD symptoms. While different SSRIs may be used based on individual patient response and tolerability, Paroxetine stands out as a well-established option for treating OCD. Fluoxetine (Choice A) is another SSRI commonly used for OCD, but Paroxetine is more commonly associated with this indication. Citalopram (Choice B) and Escitalopram (Choice D) are also SSRIs but are not typically the first choice for treating OCD.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. Venlafaxine, an SNRI, can lead to hypertension as a side effect. This medication can cause an increase in blood pressure, particularly at higher doses. Educating the patient about this potential adverse effect is crucial to enhance awareness and monitoring for any signs or symptoms of elevated blood pressure. Choices B, C, and D are incorrect because venlafaxine is more likely to cause hypertension rather than hypotension, bradycardia, or hyperglycemia.

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: B

Rationale: When initiating fluoxetine therapy in a patient with major depressive disorder, monitoring for suicidal ideation is crucial due to the increased risk of suicidal thoughts or behaviors that can occur, especially in the initial phase of treatment. This close monitoring is essential to ensure patient safety and intervene promptly if such symptoms arise. Weight gain, hypertension, and hyperglycemia are potential side effects of some medications used to treat depression, but suicidal ideation is the most critical and immediate side effect to monitor for when starting fluoxetine.
