Question 1 of 5
A 21-year-old male has recently begun pimozide therapy for Tourette disorder. His parents bring him to the emergency department. They describe that he has been having 'different-appearing tics' than before, such as prolonged contraction of the facial muscles. While being examined, he experiences opisthotonos (type of extrapyramidal spasm of the body in which the head and heels are bent backward and the body is bowed forward). Which of the following drugs would be beneficial in reducing these symptoms?
Correct Answer: A
Rationale: Pimozide, a D2 antagonist for Tourette's, can cause acute dystonia (prolonged muscle contractions, opisthotonos) as an extrapyramidal symptom due to dopamine blockade. Benztropine, an anticholinergic, restores dopamine-acetylcholine balance in the basal ganglia, rapidly relieving dystonia by reducing cholinergic overactivity. Bromocriptine, a dopamine agonist, might theoretically help but isn't standard for acute EPS. Lithium treats bipolar disorder, not EPS. Prochlorperazine, an antipsychotic, worsens dystonia. Risperidone adds D2 blockade. Benztropine's proven efficacy in acute dystonia, per clinical guidelines, makes it the best intervention here.
Question 2 of 5
An adolescent client will receive Depo-Provera as a method of birth control. She asks the nurse how long the drug will be effective. What is the best response by the nurse?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A client is prescribed fluoxetine (Prozac) for depression. Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: Fluoxetine, an SSRI, treats depression but interacts with alcohol, worsening sedation or mood , indicating a teaching gap'clients must avoid it. Feeling better in weeks aligns with SSRI onset. Reporting suicidal thoughts is critical due to early risk. Morning dosing prevents insomnia. Drinking wine risks treatment failure or safety issues, critical in depression where stability is fragile. Further teaching must clarify this interaction, ensuring fluoxetine's efficacy and client well-being, making B the statement needing correction.
