ATI LPN Pharmacology Quiz Questions
Extract:
Question 1 of 5
The patient with tuberculosis is now on isoniazid (INH). Which laboratory test should the nurse monitor?
Correct Answer: A
Rationale: Isoniazid is hepatotoxic, potentially causing liver damage, so monitoring liver function tests (LFTs) is essential to detect early hepatotoxicity. PT/PTT (clotting), BUN (kidney), and CBC (general health) are not primarily affected by INH.
Question 2 of 5
The client asks the nurse which type of diabetes is caused by no insulin secretion by the pancreas. What is the best response by the nurse?
Correct Answer: D
Rationale: Type 1 diabetes is caused by autoimmune destruction of pancreatic beta cells, resulting in no insulin secretion, requiring insulin therapy. Type 2 diabetes involves insulin resistance and relative deficiency, not a complete lack of insulin. The other options misrepresent the pathophysiology of diabetes types.
Question 3 of 5
A nurse is preparing to administer ondansetron 4 mg IM stat. The amount available is ondansetron for injection 2 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 2
Rationale: Using Volume (mL) = Dose (mg) ÷ Concentration (mg/mL), for a 4 mg dose and 2 mg/mL concentration, Volume = 4 ÷ 2 = 2 mL, a whole number as required.
Question 4 of 5
The nurse is screening a group of clients. Which client has the greatest risk for developing type 2 diabetes?
Correct Answer: C
Rationale: Being overweight, especially with central adiposity, is a significant risk factor for Type 2 diabetes, and risk increases with age, particularly over 45. A 55-year-old female who is 20 pounds overweight has the highest risk among the options. Arthritic pain, normal weight in youth, or developmental delay do not directly correlate with increased Type 2 diabetes risk unless accompanied by obesity or inactivity.
Question 5 of 5
Which hormone released by the Islets of Langerhans, acts to increase blood glucose?
Correct Answer: A
Rationale: Glucagon, secreted by pancreatic alpha cells in the Islets of Langerhans, raises blood glucose by promoting glycogenolysis and gluconeogenesis. Insulin, also from the Islets, lowers glucose, making glucagon the correct answer.
