Final answer:
Tetracycline is contraindicated in pregnancy due to potential adverse effects on fetal bone and teeth development. Therefore, the nurse should recognize that Tetracycline should not be given to the pregnant patient.
Step-by-step explanation:
The nurse should identify that pregnancy is contraindicated for receiving Tetracycline, as it is known to be associated with adverse effects on the development of bones and teeth in the fetus. Therefore, the correct answer is C) Tetracycline. This antibiotic can lead to discoloration of the teeth and possible inhibition of bone growth. While Erythromycin and Azithromycin are both macrolides, they are generally considered safer alternatives during pregnancy. Ciprofloxacin is also not recommended during pregnancy but is not selected in this context because Tetracycline is more clearly contraindicated.
