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. A client with chronic obstructive pulmonary disease (COPD) is prescribed tiotropium (Spiriva). Which instruction should the nurse include in the teaching plan?
- A. Use the medication as a rescue inhaler.
- B. Rinse your mouth after using the inhaler.
- C. Take the medication on an empty stomach.
- D. Take the medication with a full glass of water.
Correct answer: B
Rationale: Tiotropium (Spiriva) is not a rescue inhaler but a maintenance medication for COPD. The correct instruction for the nurse to include in the teaching plan is to advise the client to rinse their mouth after using the inhaler. This practice helps prevent dry mouth and throat irritation, common side effects of tiotropium. There are no specific recommendations to take tiotropium on an empty stomach or with a full glass of water.
3. While assisting in caring for a pregnant client receiving intravenous magnesium sulfate for preeclampsia management, a nurse notes the client's absent deep tendon reflexes. What determination should the nurse make based on this data?
- A. The magnesium sulfate is effective.
- B. The infusion rate needs to be increased.
- C. The client is experiencing cerebral edema.
- D. The client is experiencing magnesium toxicity.
Correct answer: D
Rationale: When a pregnant client receiving intravenous magnesium sulfate for preeclampsia management exhibits absent deep tendon reflexes, this indicates magnesium toxicity. Magnesium toxicity can occur as a complication of magnesium sulfate therapy, leading to suppressed reflexes. It is crucial for the nurse to recognize this sign promptly and report it to prevent further complications or harm to the client.
4. A client is prescribed nitroglycerin (Nitro-Dur) transdermal patch for angina. Which instruction should the nurse include in the client's teaching plan?
- A. Apply the patch to a hairless area of skin.
- B. Leave the patch on for 24 hours.
- C. Apply the patch at the same time each day.
- D. You can keep the patch on while taking a shower.
Correct answer: C
Rationale: The correct instruction for the nurse to include in the client's teaching plan is to apply the nitroglycerin (Nitro-Dur) transdermal patch at the same time each day. This consistency helps maintain steady blood levels of the medication. While it is important to apply the patch to a hairless area of the skin for proper absorption, it does not necessarily have to be left on for 24 hours; typically, it is worn for 12-14 hours to allow for a nitrate-free period and reduce tolerance. Additionally, the patch can generally be kept on while taking a shower, as water exposure does not typically affect its efficacy.
5. A client is instructed to take levothyroxine (Synthroid). The medication should be taken:
- A. With food
- B. At lunchtime
- C. On an empty stomach
- D. At bedtime with a snack
Correct answer: C
Rationale: Levothyroxine should be taken on an empty stomach to enhance absorption. Taking it with food or at bedtime can interfere with its absorption, reducing its effectiveness. Therefore, it is essential for the client to take levothyroxine on an empty stomach to ensure optimal therapeutic outcomes.
