ATI Pharmacology Practice B Questions
Question 1 of 5
A 33-year-old female is brought to the emergency department by her mother. The patient had a sudden onset of fever and her temperature is now 40°C (104°F). She has no sick contacts. The mother mentions that she is on a medication for schizophrenia but could not remember the name. A complete blood count shows 250 neutrophils per microliter. Which of the following medications is she likely taking?
Correct Answer: A
Rationale: Fever and severe neutropenia (250 neutrophils/μL) in a schizophrenic patient suggest clozapine . Clozapine causes agranulocytosis, a rare but serious side effect requiring monitoring. Olanzapine , Quetiapine , Risperidone , and Haloperidol (E) rarely cause this. Clozapine's risk explains the acute presentation, necessitating immediate cessation.
Question 2 of 5
A 53-year-old man with chronic neuropathic back pain and depression is managed with amitriptyline. He has recently complained of urinary frequency and was given a prescription for Ditropan. He now complains of acute abdominal pain and is unable to pass flatus or bowel movement. What is the most likely explanation of this finding?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A child is experiencing absence seizures that interrupt his ability to pay attention during school and activities. Which of the following therapies would be most appropriate for this patient?
Correct Answer: A
Rationale: Ethosuximide treats absence seizures by blocking T-type calcium channels in thalamic neurons, reducing 3 Hz spike-and-wave discharges that disrupt attention, ideal for school-aged children. Carbamazepine, a sodium channel blocker, controls focal and tonic-clonic seizures but worsens absence seizures. Diazepam manages acute seizures, not chronic absence. Carbamazepine plus primidone targets other seizure types, not absence. Watchful waiting risks educational impact. Ethosuximide's specificity, efficacy, and pediatric safety make it the most appropriate, per guidelines.
Question 4 of 5
Oral decongestants differ from intranasal decongestants in that oral decongestants
Correct Answer: B
Rationale: Oral decongestants (e.g., pseudoephedrine) act systemically, vasoconstricting vessels beyond the nose, causing effects like hypertension , unlike intranasal decongestants (e.g., oxymetazoline), which are localized but risk rebound congestion. Oral efficacy isn't inherently superior; it's slower. Rebound is nasal-specific. High efficacy is vague. Choice B highlights systemic impact, a key distinction nurses must recognize for safe administration.
Question 5 of 5
The physician prescribes fluticasone (Flonase) for the client. The nurse would hold the drug and contact the physician with which assessment finding?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
