When educating a client with a new prescription for Atorvastatin to treat Hyperlipidemia, which instruction should the nurse include?
- A. Take this medication in the morning.
- B. Avoid drinking grapefruit juice.
- C. Increase your intake of green, leafy vegetables.
- D. Expect your stools to turn clay-colored.
Correct Answer: B
Rationale: The correct instruction for the nurse to include when educating a client with a new prescription for Atorvastatin to treat Hyperlipidemia is to avoid drinking grapefruit juice. Grapefruit juice can increase the blood levels of atorvastatin, leading to an elevated risk of serious side effects such as liver damage and muscle problems. It is essential for the client to be aware of this potential interaction and to follow the nurse's advice to avoid grapefruit juice while taking Atorvastatin.
A client has a prescription for Amphotericin B. Which of the following laboratory values should be monitored by the nurse to assess for an adverse effect of this medication?
- A. Serum creatinine.
- B. Serum potassium.
- C. Serum sodium.
- D. Serum calcium.
Correct Answer: A
Rationale: Amphotericin B is known to cause nephrotoxicity, a potential adverse effect that can be monitored by checking the client's serum creatinine levels. Regular monitoring of serum creatinine helps in early identification of kidney damage and allows for timely intervention to prevent further complications.
A patient has been ordered the powdered form of the bile acid sequestrant colestipol. Which of the following does the nurse identify as true?
- A. The nurse should have the patient swallow the dose of the colestipol powder one
- C. The powder should be dissolved and immediately administere

Correct Answer: D
Rationale: The nurse should identify that colestipol should be administered 1 hour before or 4 to 6 hours after any other oral medication. This is because colestipol can interfere with the absorption of other medications due to its binding properties in the gut. Administering it separately from other medications helps to avoid any potential interaction and ensures the effectiveness of both the colestipol and other medications. Additionally, colestipol is typically taken with meals to enhance its tolerability and effectiveness in lowering cholesterol levels.
Which of the following describes the action of an agonist on a receptor.
- A. Destroys the receptor
- B. Competes with a
- C. Activates a receptor
- D. Blocks a receptor Pharmacology Final Study Guide ï‚· Which of the following is an antianginal and nitrate?
Correct Answer: C
Rationale: An agonist is a substance that binds to a receptor and activates it, leading to a biological response. Agonists mimic the action of endogenous ligands that normally bind to the receptor, resulting in activation of downstream signaling pathways. This activation can lead to various physiological effects depending on the specific receptor and pathway involved. In contrast, antagonists block or inhibit the actions of agonists by binding to the receptor without activating it, therefore not producing a response. Therefore, the correct answer is that an agonist activates a receptor.
A patient taking imatinib voices concern about gaining 5 pounds in the past week. Which response by the nurse is correct?
- A. Weight gain is a common side effect of imatinib.
- B. You should stop taking imatinib immediately.
- C. This is likely due to fluid retention, which is dangerous.
- D. You must follow a strict diet to avoid further weight gain.
Correct Answer: A
Rationale: Weight gain is a known side effect of imatinib, a tyrosine kinase inhibitor used to treat certain cancers. The nurse should reassure the patient that this is a common occurrence and not necessarily dangerous. However, the patient should be monitored for signs of fluid retention, such as swelling or shortness of breath, which could indicate a more serious condition. Stopping the medication abruptly is not recommended unless advised by the healthcare provider. Dietary changes may help, but they should be discussed with the healthcare team to ensure they do not interfere with treatment.
