have one's hands full困难

Primary care providers have their hands full and may not be able to follow through with patients who have trouble driving because they can’t turn their heads or remember where they are going — or have gotten shorter and haven’t changed their seat settings sufficiently to reach car pedals easily.

初级保健医生忙得不可开交，可能无法对那些驾驶有困难的病人进行跟进——这些病人或是因为无法转头、记不住要去哪里，或是因为身高变矮却没有充分调整座椅，以致难以轻松踩到踏板。
