Question 1 of 5
Children younger than 9 years should not be given tetracyclines because:
Correct Answer: D
Rationale: The correct answer is D: Children's teeth may become discoloured. Tetracyclines can bind to calcium in developing teeth, causing permanent discoloration in children younger than 9 years. This is due to the deposition of the drug within the dentin and enamel of the teeth during their development. This effect is particularly pronounced during the second half of pregnancy and in children up to 8 years of age.
Choice A is incorrect because tetracyclines primarily affect teeth, not cartilage development.
Choice B is incorrect as dehydration is not a direct side effect of tetracyclines.
Choice C is incorrect as photosensitivity is more commonly associated with other antibiotics like fluoroquinolones.
