Explanation
•Safety of the nurse and patient is the first priority. Since this patient may be a danger to herself or the nurse, the nurse should first assess the safety of the situation and approach the patient while speaking in a calm voice to ensure the patient does not become startled or aggressive.
•Restraining the patient before assessing her is not appropriate.
•Going to the patient's side and moving the glass should be done after the nurse confirms that the environment is safe.
