HESI Pharmacology Practice Exam
1. A client is taking lansoprazole (Prevacid) for the chronic management of Zollinger-Ellison syndrome. The nurse advises the client to take which of the following products if needed for a headache?
- A. Naproxen (Aleve)
- B. Ibuprofen (Advil)
- C. Acetaminophen (Tylenol)
- D. Acetylsalicylic acid (aspirin)
Correct answer: C
Rationale: Acetaminophen is the preferred choice for pain relief in individuals taking lansoprazole for Zollinger-Ellison syndrome due to its lower risk of stomach irritation compared to NSAIDs like ibuprofen and aspirin. Naproxen, ibuprofen, and aspirin are NSAIDs that can increase the risk of stomach irritation and bleeding, which is why they are not recommended for individuals with Zollinger-Ellison syndrome who are already on lansoprazole to reduce stomach acid production.
2. The healthcare provider is applying a topical corticosteroid to a client with eczema. The healthcare provider should monitor for the potential of increased systemic absorption of the medication if the medication were being applied to which of the following body areas?
- A. Back
- B. Axilla
- C. Soles of the feet
- D. Palms of the hands
Correct answer: B
Rationale: The axilla has thinner skin, making it more permeable to topical medications. Areas with thinner skin, like the axilla, allow for higher systemic absorption of topical corticosteroids.
3. Salicylic acid is prescribed for a client with a diagnosis of psoriasis. The nurse monitors the client, knowing that which of the following would indicate the presence of systemic toxicity from this medication?
- A. Tinnitus
- B. Diarrhea
- C. Constipation
- D. Decreased respirations
Correct answer: A
Rationale: The correct answer is A: Tinnitus. Salicylic acid can lead to systemic toxicity, known as salicylism, which may manifest with symptoms like tinnitus, dizziness, hyperventilation, and mental disturbances. Tinnitus is a common early sign of salicylism and should be monitored closely by the nurse to prevent further complications.
4. The client who chronically uses nonsteroidal anti-inflammatory drugs (NSAIDs) has been taking misoprostol (Cytotec). The nurse determines that the medication is having the intended therapeutic effect if which of the following is noted?
- A. Resolved diarrhea
- B. Relief of epigastric pain
- C. Decreased platelet count
- D. Decreased white blood cell count
Correct answer: B
Rationale: Misoprostol is a gastric protectant administered to clients using NSAIDs to prevent gastric mucosal injury. Relief of epigastric pain signifies the medication's therapeutic effect as it indicates a reduction in gastrointestinal symptoms associated with NSAID use.
5. Atenolol hydrochloride (Tenormin) is prescribed for a hospitalized client. The nurse should perform which of the following as a priority action before administering the medication?
- A. Listen to the client's lung sounds.
- B. Check the client's blood pressure.
- C. Check the recent electrolyte levels.
- D. Assess the client for muscle weakness.
Correct answer: B
Rationale: Atenolol hydrochloride is a beta-blocker used to treat hypertension. Checking the client's blood pressure is crucial before administration.
