The correct answer is C. Hypercyanotic spells can be precipitated by activity. Being able to identify and intervene early by recording and monitoring the circumstances surrounding the spells may help to decrease the incidence. The knee-chest position can help with the immediate problem but will not reduce the number of hypercyanotic spells. Arterial blood gases will be drawn and monitored but this will not reduce the number of hypercyanotic spells. The health care provider would not need to be contacted at this point.
