If a court directs a respondent who was previously ordered taken into immediate custody under section 125.81 to be placed at a facility for evaluation and appropriate treatment under section 125.83, and no suitable facility can immediately admit the respondent, the respondent shall remain in custody as previously ordered by the court, notwithstanding the time limits stated in section 125.81, until a suitable facility can admit the respondent. The court shall take appropriate steps to expedite the admission of the respondent to a suitable facility at the earliest feasible time.
