Nursing Elites

1. A patient with major depressive disorder is started on venlafaxine. Which class of antidepressant does this medication belong to?

• A. Selective serotonin reuptake inhibitors (SSRIs)
• B. Tricyclic antidepressants (TCAs)
• C. Monoamine oxidase inhibitors (MAOIs)
• D. Serotonin-norepinephrine reuptake inhibitors (SNRIs)

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.

2. Which characteristic identified during an assessment serves to support a diagnosis of disruptive mood dysregulation disorder? Select one that doesn't apply.

• A. Female
• B. 7 years old
• C. Comorbid autism diagnosis
• D. Outbursts occur at least once a week

Correct answer: C

Rationale: Characteristics such as age, frequency of outbursts, and occurrence in multiple settings support a diagnosis of disruptive mood dysregulation disorder. While comorbid conditions like autism can coexist with disruptive mood dysregulation disorder, it is not a characteristic that serves to support a diagnosis of this specific disorder.

3. Which of the following is not a potential side effect of electroconvulsive therapy (ECT)?

• A. Short-term memory loss
• B. Headache
• C. Confusion
• D. Tardive dyskinesia

Correct answer: D

Rationale: Electroconvulsive therapy (ECT) can have side effects such as short-term memory loss, headache, confusion, and nausea. Tardive dyskinesia is not a side effect of ECT; it is a movement disorder associated with long-term use of certain medications, particularly antipsychotics.

4. A client diagnosed with post-traumatic stress disorder (PTSD) is being assessed by a healthcare professional. Which symptom would the healthcare professional expect the client to exhibit?

• A. Delusions of grandeur
• B. Hypervigilance
• C. Obsessive-compulsive behaviors
• D. Periods of excessive sleeping

Correct answer: B

Rationale: In individuals with post-traumatic stress disorder (PTSD), hypervigilance is a common symptom. Hypervigilance refers to a state of increased alertness, awareness, and sensitivity to potential threats or danger. This heightened state of vigilance can manifest as being easily startled, having difficulty relaxing or sleeping, and constantly scanning the environment for signs of danger. It is an adaptive response to the trauma experienced and can significantly impact the individual's daily functioning. The other options are not typically associated with PTSD. Delusions of grandeur are more commonly seen in certain psychiatric disorders like bipolar disorder or schizophrenia. Obsessive-compulsive behaviors are characteristic of obsessive-compulsive disorder (OCD), not PTSD. Periods of excessive sleeping may be seen in conditions like depression, but they are not a hallmark symptom of PTSD.

5. A client has been prescribed diazepam (Valium) for the treatment of anxiety. Which of the following instructions should the nurse include in the discharge teaching?

• A. Avoid drinking alcohol while taking this medication.
• B. Take the medication with food to avoid stomach upset.
• C. Stop taking the medication if you feel better.
• D. Double the dose if you miss a dose.

Correct answer: A

Rationale: The correct instruction is to avoid drinking alcohol while taking diazepam (Valium) as it can potentiate the sedative effects and increase the risk of side effects such as drowsiness and dizziness. Taking the medication with food may help reduce stomach upset, but avoiding alcohol is crucial to ensure safe and effective use of diazepam. Choice B is partially correct, as taking the medication with food can indeed help with stomach upset, but it is not as crucial as avoiding alcohol. Choice C is incorrect because abruptly stopping diazepam can lead to withdrawal symptoms and should only be done under medical supervision. Choice D is incorrect as doubling the dose is dangerous and should never be done without healthcare provider approval.
