Question 1 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 2 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 3 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.
Question 4 of 5
A busy patient with many responsibilities is to have a medication ordered to treat her hypertension. To increase compliance with drug therapy, what drug would be a good choice for this patient?
Correct Answer: D
Rationale: Metoprolol would be the best choice because it has an extended-release form that only needs to be taken once a day, which should increase patient compliance. Acebutolol, atenolol, and bisoprolol do not come in extended-release forms. The nurse should consider the patient’s lifestyle and preferences when selecting antihypertensive medications to improve adherence.
