Question 1 of 5
A patient tells the nurse that he likes to eat large amounts of garlic to help lower his cholesterol levels naturally. The nurse reviews his medication history and notes that which drug has a potential interaction with the garlic?
Correct Answer: B
Rationale: Garlic is known to have antiplatelet and anticoagulant properties. When taken in large amounts, garlic can enhance the effects of anticoagulant medications like warfarin (Coumadin), which can increase the risk of bleeding. Therefore, it is crucial for patients on warfarin therapy to avoid consuming excessive amounts of garlic or garlic supplements to prevent potential interactions and complications.
Question 2 of 5
A client with bell's palsy tells the nurse that acetaminophen (Tylenol) is taken daily as prescribed by the physician. Which laboratory value would indicate a toxicity of the medication?
Correct Answer: A
Rationale: Acetaminophen (Tylenol) is primarily metabolized in the liver. Hepatotoxicity is a serious potential side effect of acetaminophen overdose or excessive use. One of the markers for liver damage due to acetaminophen toxicity is an elevated blood urea nitrogen (BUN) level. Normal BUN levels range from 7 to 20 mg/dl, and a level of 60 mg/dl indicates kidney dysfunction, which can result from liver damage caused by acetaminophen toxicity. Therefore, an elevated BUN level would indicate a toxicity of acetaminophen in this client with Bell's palsy who is taking acetaminophen daily. The other laboratory values mentioned are not specific markers for acetaminophen toxicity.
Question 3 of 5
What is the expected outcome for Valproate?
Correct Answer: D
Rationale: Valproate is an anticonvulsant medication commonly used to treat seizure disorders such as epilepsy. It works by stabilizing electrical activity in the brain, which helps to reduce the occurrence of seizures. Therefore, the expected outcome of Valproate treatment is a decrease in seizure activity and an improvement in seizure control.
Question 4 of 5
What is the classification for the drug valproate?
Correct Answer: B
Rationale: Valproate is classified as an anti-convulsant medication. It is commonly used to treat seizures, particularly in the management of epilepsy. Valproate works by affecting certain chemicals in the brain to control seizures and stabilize mood in some psychiatric conditions. It is not classified as an anti-diabetic, anti-ulcer agent, or anti-hypertensive medication.
Question 5 of 5
What is the therapeutic classification of Metformin?
Correct Answer: D
Rationale: Metformin belongs to the therapeutic classification of antidiabetic agents. It is commonly used to treat type 2 diabetes by helping to control blood sugar levels. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity in the body's tissues. This helps the body use insulin more effectively, leading to better blood sugar control.
