ATI Proctored Pharmacology 2024 Questions
Question 1 of 5
The client is receiving a brand name drug and wants to change to the generic form because it is cheaper. What is the best outcome for this client?
Correct Answer: A
Rationale: Understanding two differences (e.g., cost, inactive ingredients) between brand and generic drugs empowers the client to make informed choices, the best outcome. Sticking to brand after physician talk assumes preference. Asking why brand is better misaligns-generics are equivalent. Cost reduction methods are practical but secondary to comprehension. Knowledge of differences supports the switch, aligning with cost-saving goals.
Question 2 of 5
The nurse administers lorazepam (Ativan) to a client with anxiety. Which statement by the client indicates understanding of the medication?
Correct Answer: B
Rationale: Lorazepam, a benzodiazepine, reduces anxiety via GABA enhancement but potentiates CNS depression with alcohol, risking sedation or respiratory failure. Avoiding alcohol shows understanding of this danger, key for safety. Driving is unsafe due to drowsiness. It doesn't cure anxiety 'it's symptomatic relief. Extra doses risk dependence. Avoiding alcohol aligns with lorazepam's pharmacology, critical in anxiety management where misuse is common, making B the statement reflecting proper education.
Question 3 of 5
A liquid preparation of K penicillin V contains 125mg/5ml. If you want a patient to take 250mg. each dose, you would prescribe ___ per
Correct Answer: C
Rationale: To prescribe 250mg of K penicillin V, you would need to have 10ml of the liquid preparation (125mg/5ml x 10ml = 250mg). Since 1 teaspoon (tsp) is approximately equal to 5ml, you would need to prescribe 2 teaspoons of the liquid preparation for the patient to take 250mg per dose.
Question 4 of 5
A 52-year-old man who works as an air traffic controller has seasonal allergies. Currently, he is very symptomatic but cannot miss work because of staffing issues. Which of the following agents would be best suited for this patient?
Correct Answer: D
Rationale: An air traffic controller needs a non-sedating allergy treatment. Fexofenadine , a second-generation antihistamine, avoids drowsiness. Chlorpheniramine , Diphenhydramine , and Doxylamine sedate. Hydroxylamine (E) isn't a drug. Fexofenadine ensures safety and efficacy for his job.
Question 5 of 5
Action of fibrinolytic drugs
Correct Answer: C
Rationale: Fibrinolytic drugs act by promoting the breakdown of blood clots or thrombi. These drugs activate plasminogen, which is present in the blood, to form plasmin. Plasmin is an enzyme that directly breaks down fibrin, the main protein in blood clots, thus dissolving the clot and facilitating the restoration of blood flow in the affected area. This mechanism of action helps in treating conditions such as acute myocardial infarction (heart attack) and ischemic stroke, where rapid clot dissolution is crucial to prevent tissue damage.
