HESI Pharmacology Practice Exam Questions
Question 1 of 5
Nalidixic acid (NegGram) is prescribed for a client with a urinary tract infection. On review of the client's record, the nurse notes that the client is taking warfarin sodium (Coumadin) daily. Which prescription should the nurse anticipate for this client?
Correct Answer: B
Rationale: Nalidixic acid can intensify the effects of oral anticoagulants by displacing these agents from binding sites on plasma proteins. When an oral anticoagulant, like warfarin sodium (Coumadin), is combined with nalidixic acid, a decrease in the anticoagulant dosage may be necessary to avoid excessive anticoagulation and potential bleeding risks.
Question 2 of 5
A client is receiving an intravenous (IV) infusion of an antineoplastic medication. During the infusion, the client complains of pain at the insertion site. The nurse notes redness and swelling at the site, along with a slowed infusion rate. What is the appropriate action for the nurse to take?
Correct Answer: A
Rationale: When a client complains of pain at the IV insertion site, and there are signs of extravasation such as redness and swelling, it is crucial to notify the healthcare provider immediately. Extravasation of antineoplastic medications can cause tissue damage, pain, and necrosis if they escape into surrounding tissues. Prompt action is necessary to prevent further complications and ensure appropriate management of the situation.
Question 3 of 5
A client with Crohn's disease is scheduled to receive an infusion of infliximab (Remicade). The nurse assisting in caring for the client should take which action to monitor the effectiveness of treatment?
Correct Answer: B
Rationale: To monitor the effectiveness of infliximab (Remicade) treatment in a client with Crohn's disease, the nurse should observe the frequency and consistency of bowel movements. Infliximab is an immunomodulator that works to reduce inflammation in the colon, leading to improvements in bowel symptoms such as frequency and consistency. Monitoring these bowel patterns can provide valuable insight into the response to the medication and the overall management of Crohn's disease.
Question 4 of 5
A client is taking lansoprazole (Prevacid). On data collection, which question should the nurse ask to determine medication effectiveness?
Correct Answer: B
Rationale: Lansoprazole is a gastric acid pump inhibitor commonly used to treat gastroesophageal reflux disease (GERD) by reducing stomach acid. Heartburn is a key symptom of GERD, so asking about heartburn can help assess the effectiveness of lansoprazole in managing acid reflux symptoms.
Question 5 of 5
Bethanechol chloride (Urecholine) is prescribed for a client with urinary retention. Which disorder would be a contraindication to the administration of this medication?
Correct Answer: B
Rationale: Bethanechol chloride (Urecholine) should not be administered to clients with urinary strictures as it can contract the bladder and increase pressure within the urinary tract. In individuals with urinary strictures, this elevated pressure may lead to bladder rupture. Therefore, caution is advised when considering the use of Bethanechol chloride in clients with urinary strictures to prevent potential complications.
