A nurse is preparing to administer methylergonovine IM to a client who experienced a vaginal delivery. The nurse should explain to the client that the purpose of this medication is to prevent which of the following conditions?

A. Using a suction catheter is appropriate but may not be the quickest method for immediate airway clearance in this situation.
B. Suctioning the mouth with a bulb syringe is the priority action as it helps clear the airway of secretions and prevents aspiration, ensuring the newborn can breathe effectively.
C. Turning the newborn on his side can help with drainage but does not actively clear the airway, making it a less immediate priority.
D. Suctioning the nose is important, but the mouth should be cleared first to ensure a patent airway, making this option secondary.

a. "Place the retainer clip across the newborn's abdomen":

• This statement is incorrect and potentially dangerous. The retainer clip should be positioned at the level of the armpits to secure the harness straps. Placing it across the abdomen could cause abdominal injury in the event of sudden braking or a crash.

b. "Keep the car seat rear-facing until the newborn can sit unsupported":

• While this is generally true and important safety advice, it is not directly related to the positioning of the newborn in the car seat. Instead, it addresses the orientation of the car seat itself. Rear-facing car seats are safer for infants as they provide better protection for the head, neck, and spine in the event of a crash.

c. "Position the newborn at a 45-degree angle in the car seat":

• This is the correct recommendation. Newborns should be positioned at a 45-degree angle in the car seat to prevent their head from falling forward and potentially obstructing their airway. Many car seats come with angle adjusters or indicators to help achieve this optimal positioning.

d. "Place the shoulder harness straps below the level of the newborn's armpits":

• Placing the shoulder harness straps below the level of the newborn's armpits is incorrect. The straps should be positioned at or slightly below the level of the shoulders to provide proper restraint. Placing them too low increases the risk of the baby slipping out of the harness in the event of a crash.
