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 nurse is providing instructions to an adolescent who has a history of seizures and is taking an anticonvulsant medication. Which of the following statements indicates that the client understands the instructions?

Correct Answer: C

Rationale: Alcohol lowers the seizure threshold and should be avoided by individuals taking anticonvulsants.

Question 3 of 5

When reviewing laboratory results for a client receiving tacrolimus (Prograf), which laboratory result would indicate to the nurse that the client is experiencing an adverse effect of the medication?

Correct Answer: A

Rationale: An elevated blood glucose level of 200 mg/dL indicates an adverse effect of tacrolimus. This finding suggests hyperglycemia, which is a known adverse effect of the medication. Other potential adverse effects of tacrolimus include neurotoxicity and hypertension. Monitoring blood glucose levels is crucial to detect and manage this adverse effect promptly.

Question 4 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.

Question 5 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.
