Answer to Question 1

A
In the third trimester, drugs excreted by the kidneys may have to be increased, because renal blood flow is doubled, the glomerular filtration rate is increased, and drug clearance is accele-rated. Hepatic metabolism increases, meaning that drugs metabolized by the liver must be in-creased. All drugs can cross the placenta. Anatomic defects are more likely to occur in the em-bryonic period, which is in weeks 3 through 8 in the first trimester.

Answer to Question 2

D
Spironolactone takes up to 48 hours for its effects to develop, so it should not be used when the patient needs immediate diuresis. This patient has shortness of breath, crackles, and edema and needs a short-acting diuretic, such as furosemide. Asking the patient about the use of salt substi-tutes is not indicated. The patient does not need assessment of serum electrolytes.
