ATI Pharmacology Proctored Exam Practice Questions Questions
Question 1 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 2 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: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 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.
Question 4 of 5
Antihistamines block the actions of histamine at the
Correct Answer: A
Rationale: Antihistamines for allergies (e.g., diphenhydramine) target H1 receptors , blocking histamine's effects like itching or sneezing. B1 and B2 receptors (choices B, C) involve adrenergic responses (e.g., heart rate, bronchodilation), unrelated to histamine. C1 isn't a recognized receptor. H1 blockade is the mechanism for allergy relief, making choice A correct, reflecting antihistamines' specific pharmacological action critical for nurses to understand.
Question 5 of 5
