If, upon examination, the physician or physician assistant who meets the qualifications set forth in the definition of a mental health professional in section 228.1 decides that the respondent should be admitted to the hospital, the respondent shall be provided a proper bed in the hospital. The physician or physician assistant who meets the qualifications set forth in the definition of a mental health professional in section 228.1 who has charge of the respondent shall proceed with observation, medical treatment, and hospital care as in the physician’s or physician assistant’s judgment are proper and necessary, in compliance with sections 229.13, 229.14, this section, and section 229.16. After the respondent’s admission, the observation, medical treatment, and hospital care of the respondent may be provided by a mental health professional, as defined in section 228.1, who is licensed as a physician, advanced registered nurse practitioner, or physician assistant.
