Answer to Question 1
A
Excessive use of steroid inhalers reduces local immune function and increases the patient's risk for oral-pharyngeal infections, including candidiasis.
Answer to Question 2
D
Tetracyclines are pregnancy category D drugs. Their use during tooth development in the last half of pregnancy and in infancy can cause a permanent yellow-gray discoloration of the teeth and make the tooth enamel thinner. So, these drugs should not be used during pregnancy or when breastfeeding except for anthrax exposure or for another serious infection that is not likely to re-spond to other antibacterial drugs.
