Rationale 3: Potassium iodide (KI) will not protect the liver from the effects of radioactive iodine.
Rationale 4: Potassium iodide (KI) will not protect the kidneys from the effects of radioactive iodine.
Global Rationale: Potassium iodide (KI) can prevent up to 100 of the radioactive iodine from entering the thyroid gland. Potassium iodide (KI) will not protect the liver, the kidneys, or the brain from the effects of radioactive iodine.
Answer to Question 2

Rationale 1: Administering the average dose of medication to a patient in severe renal failure can have mortal consequences. The consequences of recognizing that renal patients will require less-than-average doses of medications cannot be overemphasized.
Rationale 2: Knowing which drugs will increase fluid retention is important but not as important as recognizing another precaution.
Rationale 3: Ensuring that each patient's intake and output is measured precisely is important but not as important as another precaution.
Rationale 4: Recognizing which drugs are nephrotoxic is important but not as important as another precaution.
