HESI Pharmacology Practice Exam
1. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied:
- A. Immediately before swimming
- B. 15 minutes before exposure to the sun
- C. Immediately before exposure to the sun
- D. At least 30 minutes before exposure to the sun
Correct answer: D
Rationale: Chemical sunscreens are most effective when applied at least 30 minutes before exposure to the sun to allow them to penetrate the skin and provide optimal protection. Applying sunscreen immediately before swimming (Choice A) or immediately before exposure to the sun (Choice C) may not provide sufficient time for the sunscreen to be absorbed and offer proper protection. Applying sunscreen 15 minutes before sun exposure (Choice B) is also not ideal as it may not allow enough time for the sunscreen to work effectively. Therefore, the correct answer is to apply chemical sunscreen at least 30 minutes before exposure to the sun to ensure it can be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.
2. When providing instructions to a client taking ciprofloxacin (Cipro), which of the following should the nurse include in the teaching plan?
- A. Avoid taking the medication with milk or antacids.
- B. Take the medication with a multivitamin.
- C. Consume extra dairy products while taking this medication.
- D. Take the medication with food if gastrointestinal upset occurs.
Correct answer: A
Rationale: The correct answer is to avoid taking ciprofloxacin (Cipro) with milk or antacids. These can interfere with the medication's absorption. Consuming extra dairy products or taking it with a multivitamin is not recommended for the same reason. If gastrointestinal upset occurs, the medication can be taken with food to help alleviate the symptoms.
3. A healthcare professional is monitoring a client who is receiving intravenous amphotericin B. Which of the following should prompt the healthcare professional to notify the healthcare provider immediately?
- A. Fever
- B. Headache
- C. Nausea
- D. Oliguria
Correct answer: D
Rationale: Amphotericin B is known to cause nephrotoxicity, which can lead to kidney damage. Oliguria, which is decreased urine output, is a concerning sign of kidney dysfunction and should be reported promptly to the healthcare provider to prevent further complications. Fever, headache, and nausea are common side effects of amphotericin B but are not as critical as oliguria in indicating potential kidney damage.
4. Isosorbide mononitrate (Imdur) is prescribed for a client with angina pectoris. The client tells the nurse that the medication is causing a chronic headache. The nurse appropriately suggests that the client:
- A. Cut the dose in half.
- B. Discontinue the medication.
- C. Take the medication with food.
- D. Contact the healthcare provider (HCP).
Correct answer: C
Rationale: Isosorbide mononitrate can cause headaches, which usually disappear during continued therapy. Taking the medication with food or meals can help alleviate the headache. It is important to recommend this approach before considering dose adjustments or discontinuation of the medication. Contacting the healthcare provider would be necessary if the headache persists despite taking the medication with food.
5. A client is being taught about the use of enoxaparin (Lovenox) for the prevention of deep vein thrombosis. Which instruction should the nurse include in the teaching plan?
- A. Inject the medication subcutaneously.
- B. Avoid massaging the injection site after administration.
- C. Administer the medication at the same time each day.
- D. Do not expel the air bubble from the syringe before injection.
Correct answer: C
Rationale: Enoxaparin (Lovenox) is administered subcutaneously at the same time each day to maintain consistent blood levels. Injecting the medication into the muscle is incorrect, as it should be given subcutaneously. Massaging the injection site should be avoided to prevent bruising. The air bubble in the prefilled syringe should not be expelled, as it ensures the full dose is administered.
