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.

The nurse is preparing for a community education program on hypertension. Which of these parameters determine the regulation of arterial blood pressure?

Question 4 of 5
Following surgery, a client is placed on cefotaxime (Claforan). The assessment for possible adverse effects should include observing for
Correct Answer: A
Rationale: Cefotaxime, a third-generation cephalosporin, treats postoperative infections but disrupts gut flora, commonly causing diarrhea due to overgrowth of pathogens like Clostridioides difficile. This adverse effect can range from mild to life-threatening pseudomembranous colitis, making it a priority observation. Headache might occur but is less frequent and specific to cefotaxime. Constipation contrasts with its GI effects, as diarrhea is more typical, while tachycardia could signal anaphylaxis or secondary infection but isn't a primary concern. Monitoring for diarrhea allows early detection of complications, enabling prompt intervention like discontinuing the drug or starting probiotics. This focus aligns with cephalosporins' pharmacological profile, where GI disturbance is a well-documented risk, especially post-surgery when patients are vulnerable. Thus, observing for diarrhea is the nurse's key assessment, ensuring patient safety and effective management of adverse effects, making A the correct choice.
Question 5 of 5
A 38-year-old man who is obese complains of an extremely painful, swollen metatarsophalangeal joint of his left big toe. He presents to his primary care physician for evaluation. He has had two similar attacks in the past 4 years. The physician prescribes probenecid. Which of the following describes probenecid's mechanism of action?
Correct Answer: C
Rationale: Gout (recurrent toe pain) is treated with probenecid , which inhibits urate reabsorption in the proximal tubule, increasing uric acid excretion. Anti-inflammatory and leukocyte migration inhibition are colchicine's effects. Xanthine oxidase inhibition is allopurinol's. Upregulation (E) is wrong. Probenecid's uricosuric action reduces urate levels, preventing attacks.
