pregnancy. The nurse notes that the drug has a low-molecular weight. Based on this drug characteristic, the nurse understands that this drug: a. can cause greater gastrointestinal distress and hyperemesis when compared to high-molecular weight drugs. b. has reduced renal elimination resulting in toxicity when compared to high-molecular weight drugs. c. is more sensitive to metabolism by circulating maternal hormones when compared to high-molecular weight drugs. d. will be more likely to cross the placenta and affect the fetus when compared to high-molecular weight drugs. ANS: D
Low–molecular-weight drugs are more likely to cross the placental barrier when compared to high-molecular weight drugs. This characteristic does not contribute to increased GI distress or toxicity because of reduced renal elimination. Drugs with low-molecular weight are not more sensitive to metabolism by maternal hormones.
