Answer to Question 1

C
The use of histamine H2 blockers has not been studied in pregnant women and safe use has not been established. These drugs pass into breast milk so should be avoided while breastfeeding. During pregnancy, lifestyle changes (e.g., eating more slowly, eating smaller meals) should be tried first to control reflux. Pregnant women must consult with their prescriber before taking any drug for reflux.

Answer to Question 2

C
A positive reaction to a TB skin test requires that the skin around the injection site be indurated, not just red. Induration is caused by infiltration of the skin around the test site with many white blood cells, making the area red and swollen, and the tissue much harder than the surrounding normal skin. Bruising is a result of bleeding into the injection site, not infiltration and induration from white blood cells.
