ATI Pharmacology Exam Practice Questions
Question 1 of 5
Advil, Motrin, and Nuprin are examples of
Correct Answer: C
Rationale: Advil, Motrin, and Nuprin are trade (brand) names for ibuprofen, marketed by different companies, distinct from its generic name (ibuprofen) or chemical name (e.g., 2-(4-isobutylphenyl)propanoic acid). Combination names aren't a category. Trade names reflect commercial branding, familiar to clients, a key distinction in pharmacology.
Question 2 of 5
Which drug type is often used as a first-line treatment for depression due to its side effect profile?
Correct Answer: D
Rationale: SSRIs (e.g., fluoxetine) are first-line for depression-fewer side effects (e.g., no TCA sedation), per guidelines-versus MAOIs (diet risks), beta-blockers (HTN), or TCAs (anticholinergic). SSRIs' safety drives use.
Question 3 of 5
The following drugs exert their principal effects by enzyme inhibition:
Correct Answer: D
Rationale: Selegiline inhibits monoamine oxidase-B, reducing dopamine breakdown. Others, like Atropine and Amlodipine, work via different pathways or receptor mechanisms.
Question 4 of 5
A 55-year-old man with a 40 pack-year history of smoking develops agranulocytosis and some leukemic features. His physical examination of the heart, lungs, and abdomen are within normal limits. Should this disease relate to a potential toxic exposure, which of the following should be considered most likely?
Correct Answer: A
Rationale: Agranulocytosis and leukemic features in a smoker suggest benzene exposure. Benzene, in tobacco smoke, causes bone marrow toxicity. Ethylene alcohol , carbon tetrachloride , methanol , and toluene (E) don't link to leukemia. Benzene's carcinogenicity fits this profile.
Question 5 of 5
A patient was admitted to the emergency department with a pulse oximeter reading of 85% after a successful prehospital resuscitation from cardiac arrest due to an asthma attack. What is the most important initial drug to administer as ordered?
Correct Answer: D
Rationale: Oxygen is the most important initial intervention for a patient with a low pulse oximeter reading (85%) to correct hypoxia and prevent further complications. While epinephrine (A) and albuterol (C) are used to treat asthma, oxygen is the priority to address the immediate hypoxia. Sodium bicarbonate (B) is not indicated unless there is severe metabolic acidosis.
