HESI Practice Test Pharmacology
1. A client with hypertension is prescribed hydrochlorothiazide. The nurse should monitor the client for which potential side effect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: B
Rationale: When a client is prescribed hydrochlorothiazide, the nurse should monitor for hypokalemia as a potential side effect. Hydrochlorothiazide is a diuretic that can lead to potassium loss, hence monitoring potassium levels is crucial to prevent complications related to hypokalemia.
2. After a child has just returned from surgery for a tracheostomy, what is the priority nursing action?
- A. Suctioning the tracheostomy tube
- B. Changing the tracheostomy dressing
- C. Monitoring respiratory status
- D. Ensuring the tracheostomy ties are secure
Correct answer: A
Rationale: The priority nursing action after a child has undergone tracheostomy surgery is to suction the tracheostomy tube. Suctioning is crucial to maintain a clear airway, remove secretions, and prevent potential airway obstruction, which is essential for the child's respiratory function. Changing the tracheostomy dressing, while important for wound care, does not take precedence over airway clearance. Monitoring respiratory status is vital but comes after ensuring airway patency. Ensuring tracheostomy ties are secure is significant for stabilizing the tube but is not as urgent as maintaining a patent airway through suctioning.
3. What should be used to feed an infant born with a unilateral cleft lip and palate?
- A. Plastic spoon
- B. Cross-cut nipple
- C. Parenteral infusion
- D. Rubber-tipped syringe
Correct answer: B
Rationale: A cross-cut nipple is the most appropriate choice for feeding an infant with a unilateral cleft lip and palate. Using a cross-cut nipple helps regulate the flow of milk, making feeding easier for the infant and reducing the risk of aspiration. Plastic spoons, parenteral infusion, and rubber-tipped syringes are not recommended for feeding infants with cleft lip and palate as they can pose risks such as choking, aspiration, or inadequate milk intake. It is essential to choose a feeding method that minimizes these risks and ensures proper nutrition for the infant.
4. Which diet selection by a client who is depressed and taking the MAO inhibitor tranylcypromine sulfate (Parnate) indicates to the nurse that the client understands the dietary restrictions imposed by this medication regimen?
- A. Hamburger, French fries, and chocolate milkshake.
- B. Liver and onions, broccoli, and decaffeinated coffee.
- C. Pepperoni and cheese pizza, tossed salad, and a soft drink.
- D. Roast beef, baked potato with butter, and iced tea.
Correct answer: D
Rationale: The correct answer is (D) Roast beef, baked potato with butter, and iced tea. This diet selection indicates that the client understands the dietary restrictions imposed by taking tranylcypromine sulfate (Parnate) because it does not contain tyramine. Tyramine in foods can interact with MAO inhibitors like Parnate, leading to a hypertensive crisis, which is life-threatening. Choices (A, B, and C) contain foods high in tyramine like cheese, pepperoni, and chocolate, which are contraindicated for clients taking MAO inhibitors.
5. The healthcare provider notes that a client has a new prescription for 20 mEq of potassium. The IV site is inflamed but not tender, and has a blood flashback. What action should the healthcare provider take?
- A. Obtain a liter of normal saline with 20 mEq of KCl
- B. Contact the healthcare provider to clarify the prescription
- C. Withhold the prescription medication until a new IV is started
- D. Fax the prescription to the pharmacy for immediate dispensing
Correct answer: B
Rationale: The healthcare provider should contact the prescriber to clarify the prescription because an inflamed IV site may indicate potential issues with administering the medication. It is important to ensure that the prescription is appropriate and safe for the client before proceeding with administration. Option A is incorrect because administering potassium through an inflamed IV site can lead to further complications. Option C is not the best course of action as clarifying the prescription first is essential. Option D is also incorrect as the focus should be on ensuring the safety of the client before dispensing the medication.
