HESI Pharmacology Practice Exam Questions

Question 1 of 5

A client is receiving dietary instructions from a nurse regarding warfarin sodium (Coumadin) therapy. The nurse advises the client to avoid which food item?

Correct Answer: B

Rationale: Spinach is high in vitamin K, which antagonizes the effects of warfarin sodium, an anticoagulant medication. Therefore, clients taking warfarin should avoid consuming foods rich in vitamin K, like spinach, to maintain the medication's effectiveness.

Question 2 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 3 of 5

A postoperative client has received a dose of naloxone hydrochloride for respiratory depression shortly after transfer to the nursing unit from the postanesthesia care unit. After administration of the medication, the nurse checks the client for:

Correct Answer: C

Rationale: Naloxone hydrochloride is an antidote to opioids and may be administered to postoperative clients to address respiratory depression. This medication can also reverse the effects of analgesics, potentially leading to a sudden increase in pain. Therefore, the nurse must assess the client for any unexpected rise in pain levels after naloxone administration.

Question 4 of 5

A client is receiving morphine sulfate for pain management. Which assessment finding requires immediate action?

Correct Answer: C

Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a serious side effect of morphine sulfate that can lead to respiratory compromise and requires immediate intervention. Constipation, drowsiness, and nausea are common side effects of morphine but are not immediately life-threatening compared to respiratory depression.

Question 5 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.
