Which statement is the most accurate regarding medication use in pregnant women?
1. Inhaled drugs are absorbed more quickly.
2. Drug excretion rates are lowered.
3. Oral drugs' absorption rate is lowered.
4. Drug use should be avoided during pregnancy.
Correct Answer: 1
Rationale: Increases in tidal volume and pulmonary vasodilation during pregnancy lead to quicker absorption rates. Gastric emptying is delayed, leading to prolonged oral drug absorption rates. Renal blood flow is increased, leading to higher excretion rates. Some circumstances call for drug administration during pregnancy. (p. 64)
