My facilty has posted BB guidelines in every exam room and there is no bending. To Quailify for a Bottom Bunk you MUST meet at least one of the following Criteria: 1. Seizure Disorder 2.Acute Joint Injury (temporary profile only) 3.History of Back Surgery 4.History of Joint Surgery 5.Missing a limb 6.Pregnany 7. Age greater than 50 (to be determined on a case by case basis) They request a BB, we point to the sign. If they dont have any of the above they usually just say "oh,ok".
