HESI Pharmacology Practice Exam Questions
Question 1 of 5
A nurse is providing instructions to an adolescent who has a history of seizures and is taking an anticonvulsant medication. Which of the following statements indicates that the client understands the instructions?
Correct Answer: C
Rationale: Alcohol lowers the seizure threshold and should be avoided by individuals taking anticonvulsants.
Question 2 of 5
A client is prescribed allopurinol (Zyloprim) for chronic gout. Which instruction should the nurse include in the teaching plan?
Correct Answer: A
Rationale: The correct instruction for a client prescribed allopurinol (Zyloprim) for chronic gout is to take the medication with a full glass of water. This helps prevent kidney stones which can be a side effect of the medication. It is important for the client to avoid purine-rich foods to help manage gout symptoms. They should continue taking the medication even during a gout attack as prescribed by the healthcare provider. Allopurinol can be taken with or without food, so there is no need to take it on an empty stomach.
Question 3 of 5
A client is receiving furosemide (Lasix) and is being discharged. What should the nurse include in the teaching plan?
Correct Answer: C
Rationale: Furosemide (Lasix) is a diuretic that can lead to orthostatic hypotension, causing dizziness. Instructing the client to change positions slowly can help prevent this adverse effect. It is important for the client to consume foods rich in potassium to prevent hypokalemia. Taking furosemide in the morning helps reduce the need for frequent urination at night. Encouraging the client to maintain an adequate fluid intake is crucial to prevent dehydration while on this medication.
Question 4 of 5
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:
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 in advance ensures it has enough time to be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.
Question 5 of 5
A client is learning how to mix regular insulin and NPH insulin in the same syringe. Which action, if performed by the client, indicates the need for further teaching?
Correct Answer: A
Rationale: When mixing regular insulin with another insulin preparation, it is crucial to withdraw the regular insulin first to prevent contamination. NPH insulin should be drawn after the regular insulin to maintain the integrity of each insulin type. Therefore, if the client withdraws the NPH insulin first, it indicates the need for further teaching.
