Question 1 of 5
A nurse is giving dietary instructions to a client receiving levodopa. Which of the following food items should be avoided by the client?
Correct Answer: A
Rationale: Goat yogurt and other high-protein foods should be avoided when taking levodopa because protein can interfere with the absorption of the medication, reducing its effectiveness. Whole grain cereal, asparagus, and apples are not known to interact with levodopa. Therefore, goat yogurt is the food item to avoid.
Question 2 of 5
Regarding antibiotic resistance:
Correct Answer: B
Rationale: Beta-lactamase isn't the primary resistance mechanism in pneumococci (PBP alteration is), so that's false. Penicillin's poor penetration into gram-negative bacteria due to outer membranes is a true statement, a common resistance factor. Altered penicillin-binding proteins (PBPs) drive pneumococcal resistance, not the main general mechanism, though true in context. Methicillin resistance in Staph (MRSA) is due to mecA gene producing altered PBPs, not just beta-lactamase, so that's false. Penetration issues in gram-negatives are a fundamental barrier, guiding beta-lactam design like piperacillin.
Question 3 of 5
The physician ordered a brand name drug for the client, paroxetine (Paxil). After taking this medication for a year, the client tells the nurse that it is no longer working. What is the best assessment of the nurse at this time?
Correct Answer: B
Rationale: Paroxetine's effectiveness waning after a year suggests possible drug interactions reducing its levels or efficacy, a common issue needing assessment via medication review. Needing a change assumes a conclusion without evidence. Paxil and paroxetine are the same (brand vs. generic), making that question moot. Beck assessment evaluates depression, not drug failure. Interactions align with pharmacokinetic principles, offering a proactive step to identify culprits like enzyme inducers, critical for adjusting therapy.
Question 4 of 5
Graded dose-response curves are most useful for determining
Correct Answer: A
Rationale: Graded dose-response curves plot individual response intensity to dose increases (e.g., pain relief), a pharmacodynamic tool. Population curves (e.g., ED50) suit groups, not individuals. Large or small groups aggregate data, missing individual nuance. Individual focus defines graded curves, key for tailoring therapy.
Question 5 of 5
The patient has been receiving amitriptyline (Elavil) for 2 weeks. He tells the nurse he doesn't think this medicine is working, as he is still depressed. What is the best response by the nurse?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
