Your patient has been give succinylcholine in an effort to facilitate endotracheal intubation. However, you are unable to place an endotracheal tube. You should
administer neostigmine to reverse the paralysis and allow the patient to breathe spontaneously.

administer a cholinesterase inhibitor other than neostigmine.
immediately place the patient on continuous positive airway pressure (CPAP).
manually ventilate the patient until succinylcholine wears off.
