By the way, I have noticed more than once that the work of nurses is significantly underestimated, considering that they only follow the doctor's instructions. This is, of course, true, but they need a lot of endurance and whole baggage of practical knowledge to do everything correctly. After all, patients are living people who should feel comfortable, even if their blood is taken away.
For example, my friend who works as a nurse said that she also took phlebotomy courses to improve her qualifications. And not just some free courses, but these — https://phlebotomynearyou.com/what-is-a-phlebotomy-technician/.
In general, nurses, like doctors, are worthy of no less respect.
