Heart failure Hypokalemia Hypocalcemia Hyperkalemia Question 7 1 / 1 pts The nurse is reviewing medication information with a nursing student prior to administering an oral drug and notes that the drug has extensive first-pass effects. Which statement by the student indicates the student understands the concept of first-pass effect? “The first-pass effect reduces all the toxic effects of the drug" "The first-pass effect means the drug must make a second pass through the liver to make it a more active drug.” “A drug given via the oral route may be extensively metabolized by the liver before reaching the systemic circulation.” “The first-pass effect means the drug must circumvent the liver.” Question 8 1 / 1 pts The nurse prepares to change a patient’s medication from an intravenous to an oral form and notes that the oral form is ordered in a higher dose.
