ATI RN Pharmacology Proctored Exam 2023 Questions
Question 1 of 5
The client receives diphenhydramine (Benadryl) to control allergic symptoms. Which common symptom does the nurse teach the client to report to the physician?
Correct Answer: D
Rationale: Diphenhydramine's anticholinergic effects include urinary hesitancy , a serious symptom risking retention, needing physician reporting. Sedation is expected. Diarrhea and vomiting aren't typical. D prioritizes significant complications, making it the key symptom.
Question 2 of 5
The nurse is reviewing new medication orders that have been written for a newly admitted patient. The nurse will need to clarify which orders? Select all that apply.
Correct Answer: D
Rationale: Medication orders must be clear, complete, and appropriate for the patient's condition. Orders that include 'as needed' (PRN) medications, such as 'Docusate (Colace) as needed for constipation,' require clarification because they lack specific dosing instructions. The nurse must confirm the frequency, dosage, and indications for PRN medications to ensure safe administration. The other orders (Metformin, Sitagliptin, Simvastatin, and Irbesartan) are complete and do not require clarification. Therefore, the nurse should focus on clarifying the PRN order to avoid errors in medication administration.
Question 3 of 5
What is the category status for the drug Omeprazole?
Correct Answer: B
Rationale: Omeprazole is classified as an anti-ulcer agent. It belongs to a class of medications known as proton pump inhibitors (PPIs) that work by reducing the amount of acid produced in the stomach. Omeprazole is commonly used to treat conditions such as gastroesophageal reflux disease (GERD), ulcers, and Zollinger-Ellison syndrome. It is not a laxative, anti-heartburn medication, or antianemic drug.
Question 4 of 5
It is rational and advised therapeutic practice to commence treatment with the following drug using a loading dose if a rapid onset of action is required:
Correct Answer: C
Rationale: A loading dose achieves therapeutic levels quickly for drugs with long half-lives or urgent needs. Clozapine's slow titration avoids agranulocytosis, not rapid loading. Zolmitriptan, for acute migraine, acts fast without loading due to short half-life. Amiodarone, with a half-life of weeks, uses loading doses (e.g., 800-1600 mg/day) to rapidly control arrhythmias, rational for urgent onset. Levodopa's short half-life and titration in Parkinson's don't require loading. Doxazosin, for hypertension, starts low to avoid first-dose hypotension. Amiodarone's pharmacokinetics and arrhythmia urgency make loading advised, balancing efficacy and toxicity risks.
Question 5 of 5
For a drug that obeys first-order (linear) kinetics and fits a one-compartment model for elimination:
Correct Answer: A
Rationale: For first-order kinetics, the rate of elimination is directly proportional to plasma drug concentration, ensuring constant percentage clearance over time.
