HESI Pharmacology Quizlet
1. 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.
2. Cycloserine (Seromycin) is added to the medication regimen for a client with tuberculosis. Which of the following would the nurse include in the client-teaching plan regarding this medication?
- A. To take the medication after meals
- B. To return to the clinic weekly for serum drug-level testing
- C. To call the health care provider (HCP) if a skin rash occurs
- D. To restrict alcohol intake with this medication
Correct answer: B
Rationale: Cycloserine requires weekly serum drug level determinations to monitor for neurotoxicity. The medication must be taken after meals, and the client should avoid alcohol. Additionally, the client should report any signs of skin rash or central nervous system toxicity to the healthcare provider.
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. A health care provider (HCP) writes a prescription for digoxin (Lanoxin), 0.25 mg daily. The nurse teaches the client about the medication and tells the client that it is important to:
- A. Count the radial and carotid pulses every morning.
- B. Check the blood pressure every morning and evening.
- C. Stop taking the medication if the pulse is higher than 100 beats per minute.
- D. Withhold the medication and call the HCP if the pulse is less than 60 beats per minute.
Correct answer: D
Rationale: When taking digoxin, monitoring the pulse rate is essential due to its potential effects on heart rate. Digoxin can lead to bradycardia, where the pulse rate drops significantly. Withholding the medication and promptly contacting the healthcare provider if the pulse falls below 60 beats per minute is crucial to prevent severe complications and ensure appropriate management. Choices A, B, and C are incorrect because counting radial and carotid pulses, checking blood pressure, or stopping the medication based on a pulse rate higher than 100 beats per minute are not the primary monitoring parameters for a client taking digoxin.
5. Megestrol acetate (Megace), an antineoplastic medication, is prescribed for a client with metastatic endometrial carcinoma. The nurse reviews the client's history and contacts the registered nurse if which diagnosis is documented in the client's history?
- A. Gout
- B. Asthma
- C. Thrombophlebitis
- D. Myocardial infarction
Correct answer: C
Rationale: Megestrol acetate can increase the risk of thromboembolic events. Clients with a history of thrombophlebitis should not receive this medication due to the increased risk of thromboembolic events. Therefore, the nurse should contact the registered nurse if thrombophlebitis is documented in the client's history to ensure appropriate medication management.
