HESI Pharmacology Practice Exam
1. A client is receiving dietary instructions from a nurse regarding warfarin sodium (Coumadin) therapy. The nurse advises the client to avoid which food item?
- A. Grapes
- B. Spinach
- C. Watermelon
- D. Cottage cheese
Correct answer: B
Rationale: The correct answer is B: Spinach. Spinach is high in vitamin K, which antagonizes the effects of warfarin sodium, an anticoagulant medication. Clients taking warfarin should avoid consuming foods rich in vitamin K, like spinach, to maintain the medication's effectiveness. Grapes (choice A), watermelon (choice C), and cottage cheese (choice D) do not interfere with the effects of warfarin, so they are safe for the client to consume while on warfarin therapy.
2. A client with a peptic ulcer is diagnosed with a Helicobacter pylori infection. The nurse is reinforcing teaching for the client about the medications prescribed, including clarithromycin (Biaxin), esomeprazole (Nexium), and amoxicillin (Amoxil). Which statement by the client indicates the best understanding of the medication regimen?
- A. My ulcer will heal because these medications will kill the bacteria.
- B. These medications are only taken when I have pain from my ulcer.
- C. The medications will kill the bacteria and stop the acid production.
- D. These medications will coat the ulcer and decrease the acid production in my stomach.
Correct answer: C
Rationale: Triple therapy for Helicobacter pylori infection usually includes two antibacterial drugs and a proton pump inhibitor. These medications will kill the bacteria and decrease acid production.
3. A client is being monitored while receiving bethanechol chloride (Urecholine) for urinary retention. Which of the following indicates a therapeutic effect of this medication?
- A. Increased heart rate
- B. Increased peristalsis
- C. Passage of flatus
- D. Urinary output of 50 mL per hour
Correct answer: D
Rationale: Bethanechol chloride (Urecholine) is administered to stimulate the bladder and treat urinary retention. The therapeutic effect is indicated by an increased urinary output, as it demonstrates the medication's ability to prompt the bladder to empty. Increased heart rate and passage of flatus are unrelated to the therapeutic effects of bethanechol. Although bethanechol can increase peristalsis, the primary therapeutic goal is to address urinary retention.
4. The client has a PRN prescription for ondansetron (Zofran). For which condition should this medication be administered to the postoperative client?
- A. Paralytic ileus
- B. Incisional pain
- C. Urinary retention
- D. Nausea and vomiting
Correct answer: D
Rationale: Ondansetron, also known as Zofran, is an antiemetic medication primarily used to treat nausea and vomiting. In the postoperative setting, it is commonly administered to manage postoperative nausea and vomiting, which are frequent occurrences after surgery. Ondansetron works by blocking serotonin, a natural substance in the body that can trigger nausea and vomiting. It is also utilized to manage chemotherapy-induced nausea and vomiting. Therefore, the correct condition for which ondansetron should be administered to the postoperative client is nausea and vomiting.
5. A client presenting with complaints of not feeling well is seen in a clinic. The client is taking several medications for the control of heart disease and hypertension, including a beta-blocker, digoxin (Lanoxin), and a diuretic. A tentative diagnosis of digoxin toxicity is made. Which of the following assessment data would support this diagnosis?
- A. Dyspnea, edema, and palpitations
- B. Chest pain, hypotension, and paresthesia
- C. Double vision, loss of appetite, and nausea
- D. Constipation, dry mouth, and sleep disorder
Correct answer: C
Rationale: The correct answer is C. Double vision, loss of appetite, and nausea are classic signs of digoxin toxicity. Other signs may include bradycardia, visual disturbances, and confusion. These symptoms are indicators that the client may be experiencing adverse effects due to elevated levels of digoxin in the system, requiring immediate medical attention to prevent serious complications.
