Question 1 of 5
Which type of anemia is diagnosed with a Schilling test?
Correct Answer: B
Rationale: The Schilling test is used to determine the cause of vitamin B12 deficiency, a potential precursor to pernicious anemia. This test involves the use of a small oral dose of radioactive B12 and a large nonradioactive intramuscular dose. A 24-hour urine specimen is then collected to measure the amount of radioactivity in the urine, and thus radioactive B12. This test is not helpful in diagnosing aplastic, megaloblastic, or iron-deficiency anemia.
Question 2 of 5
A client is hospitalized for ingesting an overdose of acetaminophen. The nurse prepares to administer which specific antidote for this medication overdose?
Correct Answer: C
Rationale: Acetylcysteine restores sulfhydryl groups that are depleted by acetaminophen metabolism. Flumazenil is the antidote for benzodiazepine reversal. Phytonadione is the antidote for warfarin sodium. Naloxone hydrochloride reverses respiratory depression caused by an opioid.
Question 3 of 5
The nurse is preparing to administer a dose of warfarin (Coumadin) to a client. The client's International Normalized Ratio (INR) is 4.0. What should the nurse do?
Correct Answer: B
Rationale: An INR of 4.0 is above the therapeutic range (2-3), indicating a risk of bleeding, so the nurse should hold the dose and notify the physician.

Question 5 of 5
The nurse is caring for a client post-cataract surgery. Which instruction should the nurse include in discharge teaching?
