ATI Pharmacology Proctored Exam Practice Questions Questions
Question 1 of 5
A patient presents with hypotension and bradycardia. The patient indicates that one of her physicians recently prescribed three new medications to her current list of 10 medications per day. Based on this information, which statement would be the most accurate?
Correct Answer: B
Rationale: Polypharmacy-13 drugs-raises interaction risks (e.g., beta-blockers plus CCBs causing hypotension/bradycardia), a common adverse outcome in complex regimens. Allergy lacks specific signs (e.g., rash). Non-compliance isn't indicated-she reports use. Transient effects need time evidence. Polypharmacy fits symptoms, per pharmacodynamics.
Question 2 of 5
A 24-year-old sexually active woman presents to her primary care physician with vaginal itching and a greenish, frothy vaginal discharge. Her boyfriend is asymptomatic. She is prescribed metronidazole for Trichomonas vaginalis. Which of the following should be told to avoid while taking metronidazole?
Correct Answer: A
Rationale: Metronidazole treats Trichomonas vaginalis, and alcohol must be avoided. It inhibits aldehyde dehydrogenase, causing a disulfiram-like reaction (nausea, flushing). Aspirin , caffeine , grapefruit juice , and machinery (E) lack this interaction. This precaution prevents severe discomfort, ensuring treatment adherence.
Question 3 of 5
A 31-year-old woman is planning to take a 7-day cruise to the Caribbean islands. She has never been on a ship before and fears developing motion sickness. She purchases scopolamine transdermal patch. When is the best time for her to place the patch to maximize drug efficacy?
Correct Answer: D
Rationale: Scopolamine prevents motion sickness via anticholinergic action. Applying prior to symptoms -ensures prophylaxis. After nausea (A, B) or vomiting is too late. Memory loss is a side effect, not timing. Preemptive use maximizes efficacy for her cruise.
Question 4 of 5
A mother brings her unconscious 14-year-old son to the emergency department. He was found in his bedroom by his mother appearing agitated and sweaty. He complains of a feeling of ants crawling under his skin and a dry mouth. The mother suspects that he has been abusing his brother's prescription ADHD medicine, showing an empty pill bottle. What should he be given now?
Correct Answer: C
Rationale: ADHD stimulant (e.g., amphetamine) overdose (formication, dry mouth) lacks a specific antidote, but flumazenil -is listed, likely a typo for a benzo to calm agitation. Ammonium chloride , epinephrine , pilocarpine , and theophylline (E) don't fit. Benzos would address symptoms.
Question 5 of 5
A 9-year-old boy is sent for neurologic evaluation because of episodes of apparent inattention. Over the past year, the child has experienced episodes during which he develops a blank look on his face and his eyes blink for 15 seconds. He immediately resumes his previous activity. Which one the following best describes this patient's seizures?
Correct Answer: D
Rationale: Absence seizures, typical in childhood, feature brief (10-20 second) lapses in awareness with staring and eye blinking, followed by immediate resumption of activity, as described. Simple partial seizures preserve consciousness with focal symptoms (e.g., twitching). Complex partial seizures impair awareness longer, with automatisms. Tonic-clonic seizures involve convulsions. Myoclonic seizures cause jerks without staring. The short duration, blank look, and rapid recovery align with absence seizures' EEG pattern (3 Hz spike-and-wave), distinguishing it here.
