it may interfere with cartilage development
Children become dehydrated easily
photosensitivity may occur
children's teeth may become discolored
The Correct Answer is D
A. It may interfere with cartilage development: Tetracyclines can deposit in developing bones and teeth, potentially causing discoloration and affecting bone growth in children.
B. Children become dehydrated easily: While dehydration is a concern in any illness, it's not the specific reason to avoid tetracyclines in children.
C. Photosensitivity may occur: Photosensitivity can be a side effect of some medications, but it's not the main reason to avoid tetracyclines in children.
D. Children's teeth may become discoloured: Tetracycline can stain developing teeth, causing permanent discoloration. This is the major reason to avoid them in young children.
