Final answer:
Based on the assessment of the infant, advising the mother to observe the baby and call 9-1-1 again if necessary is the best course of action.
Step-by-step explanation:
In this scenario, the apneic 2-month-old male appears to be conscious, active, and breathing adequately with a normal oxygen saturation level of 98. Based on this assessment, the best course of action would be to advise the mother to observe her son and call 9-1-1 again if necessary (Option 2). Since the infant is currently in a stable condition, administering high-flow oxygen (Option 3) or requesting an ALS ambulance for transport (Option 1) would be unnecessary. Additionally, there is no indication to transport the infant to the hospital immediately (Option 4).
