ATI VATI Pharmacology Assessment Questions
Question 1 of 5
A patient complains of night blindness. The nurse correctly recommends which foods?
Correct Answer: B
Rationale: Night blindness is often caused by vitamin A deficiency. Foods rich in vitamin A, such as fortified milk and eggs, are recommended. Skim milk and peas (A), nuts and yeast (C), and enriched breads and cereals (D) are not significant sources of vitamin A.

Question 3 of 5
A patient has taken two doses of interferon Alfa-2b (Intron-A). He comes to the clinic today with the following complaints. Which symptoms would the nurse identify as common adverse effects of this therapy?
Correct Answer: A
Rationale: Interferon Alfa-2b is an immunomodulatory drug used for conditions like hepatitis or cancer, known for causing flu-like symptoms and systemic effects. Common adverse effects include dizziness, fatigue, and anorexia (loss of appetite), as listed in the correct answer (1, 3, 4). Dizziness reflects the drug's impact on the central nervous system, often reported early in therapy. Loss of appetite and fatigue are also hallmark symptoms due to interferon's influence on metabolism and energy levels. An itchy rash , while possible as a hypersensitivity reaction, is less commonly associated with interferon compared to these systemic effects. The nurse must recognize these as expected side effects, distinguishing them from severe reactions requiring intervention. Since the question asks for common adverse effects and the correct answer includes multiple symptoms, choice A (dizziness) is a key identifier among them, supported by its prevalence in clinical use, making it the primary focus here.
Question 4 of 5
Methotrexate, the most widely used antimetabolite in cancer chemotherapy does not penetrate the central nervous system (CNS). To treat CNS disease this drug must be administered:
Correct Answer: C
Rationale: Methotrexate is a drug commonly used in cancer chemotherapy due to its ability to inhibit the synthesis of DNA, RNA, and proteins necessary for cell reproduction. Unfortunately, methotrexate does not penetrate the blood-brain barrier well, which means it cannot effectively reach or treat central nervous system (CNS) diseases when administered through traditional routes like oral ingestion or intravenous injection.
Question 5 of 5
The following are substrates for CYP3A:
Correct Answer: A
Rationale: Ciclosporin is extensively metabolized by CYP3A enzymes, making it susceptible to drug interactions with inhibitors or inducers of this pathway.
