How to Study for ATI Pharmacology Proctored Exam Questions
Question 1 of 5
What is the therapeutic classification of Omeprazole?
Correct Answer: B
Rationale: Omeprazole belongs to the therapeutic class of antiulcer agents. It is a proton pump inhibitor that works by decreasing the amount of acid produced in the stomach. Omeprazole is commonly used to treat conditions such as gastroesophageal reflux disease (GERD), gastric ulcers, and duodenal ulcers. It helps reduce symptoms such as heartburn, acid reflux, and stomach pain by promoting healing of the stomach lining.
Question 2 of 5
A client who is taking Methotrexate (Trexall) asks the nurse on what is the appropriate activity while taking the medication. The nurse advised the client to play which activity?
Correct Answer: D
Rationale: Tennis is a low-impact activity that is generally safe for patients on methotrexate, as it minimizes the risk of injury and bleeding. High-impact or contact sports like basketball, ice hockey, and football are discouraged due to the increased risk of trauma and bleeding, especially since methotrexate can cause myelosuppression. Encouraging safe physical activity is important for overall health, but precautions must be taken to avoid complications.

Question 4 of 5
The mechanism of action of drugs is best determined by its:
Correct Answer: B
Rationale: Pharmacodynamics refers to the study of how drugs exert their effects on the body, including the interactions between a drug and its target molecule or receptor leading to a biological response. Understanding a drug's mechanism of action involves determining how it interacts with specific receptors, enzymes, ion channels, or other molecular targets within the body to produce the desired therapeutic effects. Pharmacokinetics, on the other hand, involves the study of how drugs move through the body, including their absorption, distribution, metabolism, and excretion, which although important for determining effective drug dosages and concentrations, does not directly provide insight into how a drug exerts its pharmacological effects. Therapeutic action refers to the overall clinical effect of the drug in treating a specific condition, which is influenced by its pharmacodynamics. Pharmaceutical preparations involve drug formulation and delivery methods, such as tablets, injections, or creams, which affect a drug's bioavailability but do not determine its specific mechanism of action.
Question 5 of 5
What agents are used primarily to treat cardiac-related conditions? (Select all that apply.)
Correct Answer: B
Rationale: Drugs that block both alpha- and beta-adrenergic receptors are primarily used to treat cardiac-related conditions. Phentolamine, a nonselective alpha-adrenergic blocking agent, is used to treat extravasation of IV norepinephrine or dopamine and hypertension related to a pheochromocytoma. Alpha1-selective adrenergic blocking agents are used for treatment of hypertension and benign prostatic hyperplasia. The beta-adrenergic blocking agents are used to treat cardiovascular problems (hypertension, angina, migraine headaches) and to prevent reinfarction after myocardial infarction. Beta1-selective adrenergic blocking agents are used for treating hypertension, angina, and some cardiac arrhythmias. The nurse should understand the indications for these agents to ensure safe and effective administration.
