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. A patient with schizophrenia is prescribed risperidone. The nurse should monitor the patient for which common side effect of this medication?

• A. Agranulocytosis
• B. Weight gain
• C. Hair loss
• D. Hyperthyroidism

Correct answer: B

Rationale: When a patient is prescribed risperidone, an atypical antipsychotic, the nurse should monitor for weight gain as it is a common side effect of this medication. Weight gain can occur due to metabolic changes and increased appetite associated with risperidone use. Agranulocytosis is a severe decrease in a type of white blood cells, and it is not a common side effect of risperidone. Hair loss and hyperthyroidism are also not typically associated with risperidone use.

3. The healthcare provider is providing medication education to a patient who has been prescribed lithium to stabilize mood. Which early signs and symptoms of toxicity should the healthcare provider stress to the patient? Select one that does not apply.

• A. Increased attentiveness
• B. Getting up at night to urinate
• C. Improved vision
• D. An upset stomach for no apparent reason

Correct answer: C

Rationale: Early signs of lithium toxicity include gastrointestinal upset, tremors, increased urination, and increased thirst. Improved vision is not a typical early sign of lithium toxicity and should be ruled out as a symptom to watch for.

4. During a treatment team meeting, the point is made that a client with schizophrenia has recovered from the acute psychosis but continues to demonstrate apathy, avolition, and blunted affect. The nurse who relates these symptoms to serotonin excess will suggest that the client receive?

• A. Chlorpromazine
• B. Phenelzine
• C. Haloperidol
• D. Olanzapine

Correct answer: D

Rationale: In this scenario, the symptoms of apathy, avolition, and blunted affect are indicative of negative symptoms commonly seen in schizophrenia. These symptoms are often associated with dopamine and serotonin imbalances in the brain. Olanzapine, an atypical antipsychotic, is known for its efficacy in treating both positive and negative symptoms of schizophrenia. It acts by blocking serotonin and dopamine receptors, helping to alleviate the symptoms mentioned. Chlorpromazine and Haloperidol are typical antipsychotics that primarily target dopamine receptors, while Phenelzine is an MAOI used to treat depression and anxiety disorders, not schizophrenia. Therefore, the most appropriate choice for this client displaying these symptoms related to serotonin excess would be Olanzapine.

5. When should healthcare professionals be most alert to the possibility of communication errors resulting in harm to the patient?

• A. Change of shift reports
• B. Admission interviews
• C. One-to-one conversations with patients
• D. Conversations with patient families

Correct answer: A

Rationale: Healthcare professionals should be most alert to the possibility of communication errors resulting in harm to the patient during change of shift reports. This is a critical time when information is transferred between healthcare providers, and any errors in communication during this handover can lead to adverse outcomes for the patient.
