Hello! The reason that nurses cannot wear gaudy jewelry is the same reason that you shouldn’t have long, loose hair or clothing in a lab setting: it may catch it things and cause harm to you or others in your environment.
For this specific question, the correct answer would be D. A confused patient can grab at the jewelry.
This could harm the nurse and the patient and jewelry is not appropriate in a medical setting as it can interfere with the healing process of patients.
Any hospital that is said to be governed publicly is fully funded by the government and operates solely off of money that is collected from taxpayers to fund healthcare initiatives.
