ATI Capstone Pharmacology Assessment 2 Questions
Question 1 of 5
Which food items should the nurse advise a patient taking a monoamine oxidase inhibitor (MAOI) to avoid?
Correct Answer: C
Rationale: MAOIs (e.g., phenelzine) with tyramine-rich foods (chocolate, wine, fava beans) risk hypertensive crisis-per pharmacology-unlike juice/cheese or water/fish. Tyramine avoidance is critical, per diet.

Question 3 of 5
Select all the early manifestations of lithium
Correct Answer: A
Rationale: Nausea is one of the early manifestations of lithium toxicity. It is important to monitor for this symptom in patients taking lithium to detect toxicity early and prevent more serious complications. Hypotension and renal failure are more severe manifestations of lithium toxicity that occur at later stages. Muscle weakness is not typically associated with early lithium toxicity.
Question 4 of 5
Thiopental is used as an anesthetic agent during surgery to repair a small-bowel obstruction in a 78-year-old man. Approximately 1 day after his surgery, toxicology studies still reveal some thiopental present in the bloodstream. What is the most likely explanation for this finding?
Correct Answer: C
Rationale: Thiopental, a barbiturate, persists 24 hours post-surgery. Physiologic metabolism is correct-its lipophilicity causes redistribution to fat, with slow hepatic metabolism, normal in the elderly. Hepatitis or insufficiency lacks evidence. Renal failure doesn't primarily clear it. Trauma (E) is unrelated. This reflects thiopental's pharmacokinetics, not pathology.
Question 5 of 5
A client with bell's palsy tells the nurse that acetaminophen (Tylenol) is taken daily as prescribed by the physician. Which laboratory value would indicate a toxicity of the medication?
Correct Answer: A
Rationale: Acetaminophen (Tylenol) toxicity primarily affects the liver and can result in hepatic injury. When the liver is damaged, it can lead to the elevation of liver enzymes and other markers of liver function. Blood urea nitrogen (BUN) is a measure of kidney function, not liver function. Therefore, an elevated BUN level would not indicate acetaminophen toxicity. In cases of acetaminophen overdose, the liver enzymes, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), would typically be elevated, indicating liver damage.
