Question 2 of 5
What drug classification is Valproate?
Correct Answer: C
Rationale: Valproate is a medication classified as an anticonvulsant, which means it is primarily used to treat seizures and epilepsy. It works by stabilizing electrical activity in the brain and helping to prevent abnormal brain signals that can lead to seizures. Valproate is also used as a mood stabilizer to treat bipolar disorder and is sometimes prescribed for migraine prevention. It is not classified as an antiarrhythmic, anticoagulant, or any other type of drug.
Question 3 of 5
The most potent of ester type of Local Anesthesia:
Correct Answer: B
Rationale: Articaine is considered the most potent ester type of local anesthetic. It is known for its high efficacy in providing profound anesthesia due to its unique chemical structure that enhances its ability to penetrate tissues effectively. Articaine also has a rapid onset of action and a relatively long duration of action compared to other ester local anesthetics. These characteristics make it a popular choice for various dental and medical procedures where deep and long-lasting anesthesia is required.
Question 4 of 5
Bactericidal action are elicited by the following, except:
Correct Answer: C
Rationale: Nystatin is an antifungal medication used to treat fungal infections caused by yeast. It works by binding to ergosterol, a component of fungal cell membranes, causing them to become porous and leaky, ultimately leading to the death of the fungus. Nystatin does not have bactericidal action because it specifically targets fungal cells and is not effective against bacteria.
Question 5 of 5
The nurse is caring for a patient who is receiving warfarin (Coumadin) and notes bruising and petechiae on the patient's extremities. The nurse will request an order for which laboratory test?
Correct Answer: B
Rationale: Bruising and petechiae on a patient's extremities are signs of potential thrombocytopenia, which is a decrease in platelet count. Warfarin (Coumadin) is an anticoagulant that works by interfering with the body's ability to use vitamin K to form blood clots. While the International normalized ratio (INR) is often used to monitor the effectiveness of warfarin therapy, and PTT and aPTT may also be relevant in certain cases, the presence of bruising and petechiae suggest a potential issue with platelet levels. Therefore, checking the patient's platelet level with a laboratory test is appropriate in this situation to assess for thrombocytopenia.
