Anursing student is measuring blood pressure (bp) of a preschooler and seeks from a nursing instructor for hearing korotkoff sounds. what should the instructor suggest to the student?

doctors i believe if i'm wrong sorry

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
