HESI Pharmacology Practice Exam
1. A client with heart failure is prescribed furosemide (Lasix) and digoxin (Lanoxin). Which instruction should the nurse include in the client's teaching plan?
- A. Avoid foods high in potassium.
- B. Report a pulse rate less than 60 beats per minute.
- C. Take the medications in the morning.
- D. Weigh yourself daily.
Correct answer: B
Rationale: The correct answer is B. The nurse should instruct the client to report a pulse rate less than 60 beats per minute, as it could indicate digoxin toxicity. Consuming potassium-rich foods is encouraged due to the potential for furosemide (Lasix) to cause hypokalemia. The medications should be taken in the morning to prevent nocturia. Weighing oneself daily is important to monitor for fluid retention, a crucial aspect in managing heart failure. Therefore, choices A, C, and D are incorrect as they do not address the specific teaching point related to digoxin and its potential toxicity.
2. A child is hospitalized with a diagnosis of lead poisoning. The healthcare provider assisting in caring for the child would prepare to assist in administering which of the following medications?
- A. Activated charcoal
- B. Sodium bicarbonate
- C. Syrup of ipecac
- D. Dimercaprol (BAL in Oil)
Correct answer: D
Rationale: Dimercaprol (BAL in Oil) is a chelating agent indicated for lead poisoning. It works by binding to lead and facilitating its removal from the body. Activated charcoal is used for certain types of poisoning by adsorbing toxins, while sodium bicarbonate can be used to treat acidosis. Syrup of ipecac is no longer recommended for poison treatment due to potential risks.
3. Before administering furosemide (Lasix) to a client with heart failure, what is the most important laboratory test result for the nurse to check?
- A. Potassium level
- B. Creatinine level
- C. Cholesterol level
- D. Blood urea nitrogen
Correct answer: A
Rationale: The correct answer is to check the potassium level before administering furosemide (Lasix) to a client with heart failure. Furosemide is a loop diuretic that can cause hypokalemia, so it is crucial to assess the potassium level to prevent complications like cardiac arrhythmias associated with low potassium levels.
4. A healthcare professional prepares to administer sodium polystyrene sulfonate (Kayexalate) to a client. Before administering the medication, the professional reviews the action of the medication and understands that it:
- A. Releases bicarbonate in exchange for primarily sodium ions
- B. Releases sodium ions in exchange for primarily potassium ions
- C. Releases potassium ions in exchange for primarily sodium ions
- D. Releases sodium ions in exchange for primarily bicarbonate ions
Correct answer: B
Rationale: Sodium polystyrene sulfonate, such as Kayexalate, is a cation exchange resin that functions by releasing sodium ions in exchange for primarily potassium ions. This medication is commonly used to treat hyperkalemia, a condition characterized by elevated levels of potassium in the blood.
5. Glimepiride (Amaryl) is prescribed for a client with diabetes mellitus. A healthcare provider reinforces instructions for the client and advises them to avoid which of the following while taking this medication?
- A. Alcohol
- B. Organ meats
- C. Whole-grain cereals
- D. Carbonated beverages
Correct answer: A
Rationale: Alcohol should be avoided when taking glimepiride (Amaryl) because it can cause a disulfiram-like reaction and enhance the hypoglycemic effects of the medication. Consuming alcohol with glimepiride can lead to symptoms such as flushing, palpitations, nausea, and vomiting. Therefore, it is crucial for individuals on glimepiride therapy to steer clear of alcohol to prevent adverse reactions and maintain optimal medication efficacy.
