ATI RN Pharmacology Proctored Exam 2023 Quizlet Questions
Question 1 of 5
The nurse manages care for several clients receiving hormone replacement therapy (HRT). What will the priority assessment by the nurse include as related to side effects?
Correct Answer: A
Rationale: HRT increases clotting risk, making calf pain a priority due to potential DVT, a life-threatening side effect. Libido , back pain , and fatigue are less urgent. A ensures safety, aligning with HRT risks, making it the priority.
Question 2 of 5
Which of the following agents exerts its therapeutic effect in multiple sclerosis via potassium channel blockade?
Correct Answer: A
Rationale: Dalfampridine treats MS by blocking potassium channels in demyelinated axons, enhancing nerve conduction and improving walking ability. Exposed potassium channels in MS leak current, impairing signal propagation; dalfampridine's blockade restores function. Donepezil boosts acetylcholine for Alzheimer's. Riluzole reduces glutamate in ALS. Bromocriptine, a dopamine agonist, manages Parkinson's. Dalfampridine's unique potassium channel action directly addresses MS's neurological deficit, supported by clinical evidence, making it the correct agent here.
Question 3 of 5
Enteric coated acetylsalicylic acid has been prescribed for a patient to treat chronic arthritis. The patient calls the clinic nurse because of gagging and difficulty swallowing the tablets. What response would the nurse give to the patient?
Correct Answer: D
Rationale: Enteric-coated tablets should not be crushed or opened, as this disrupts their protective coating and can cause gastric irritation. The patient should be instructed to swallow the tablets whole with plenty of water or milk. Crushing (A) or opening the tablets (C) is inappropriate. Notifying the healthcare provider (B) may be necessary if the patient cannot tolerate the medication.
Question 4 of 5
Which of the following is NOT an opioid or NSAID?
Correct Answer: D
Rationale: Acetaminophen is not an opioid or NSAID. It is a pain reliever and fever reducer, but it works in a different way compared to opioids and NSAIDs. Unlike opioids, acetaminophen does not have the same risk of physical dependence or addiction. And unlike NSAIDs, acetaminophen does not have anti-inflammatory properties. It is often used for mild to moderate pain relief and as a fever reducer. Be cautious when taking acetaminophen, as high doses can be harmful to the liver.
Question 5 of 5
An overwhelmed nursing student asks the instructor whether there are any tips that will make learning pharmacology easier. The instructor gives an example of the anticoagulant heparin. The instructor indicates that knowing heparin and comparing other drugs to it will facilitate learning the many anticoagulants. Which approach is the instructor using?
Correct Answer: D
Rationale: The prototype approach uses a representative drug like heparin to learn a class (anticoagulants), comparing others to its traits-mechanism, effects, side effects-simplifying study. Mechanism of action is narrower. Generic or trade names focus on nomenclature, not learning strategy. Prototype leverages a familiar example, a proven method for mastering drug groups.
