A nurse is caring for a school-age child who is postoperative following surgical removal of their tonsils. Which of the following manifestations should the nurse identify as a potential complication?

Sudden unexpected infant death (SUID), including sudden infant death syndrome (SIDS), is associated with unsafe sleep environments and certain modifiable risk factors. Prevention focuses on safe sleep practices such as supine positioning, firm sleep surfaces, and avoiding soft bedding or overheating. Room-sharing without bed-sharing is recommended because it allows close monitoring of the infant while maintaining a separate safe sleep surface. Parental education is essential to reduce risk.

Rationale:
A. Using bumper pads around the crib is unsafe because they increase the risk of suffocation, entrapment, and impaired airflow. Soft bedding items are strongly discouraged in infant sleep environments. The crib should remain free of loose or padded materials to ensure safe sleep.

B. Sharing a bedroom with the infant for the first 6 months is recommended because it allows the caregiver to closely monitor the infant during sleep while maintaining a separate safe sleep surface. Room-sharing has been shown to reduce the risk of SUID by facilitating early recognition of distress and promoting safer sleep practices.

C. Placing the infant on a soft crib mattress after 4 months is unsafe because soft sleep surfaces increase the risk of suffocation and airway obstruction. Infants should always sleep on a firm, flat mattress covered with a fitted sheet regardless of age. Soft bedding remains a risk factor throughout infancy.

D. Covering the infant with a nonflammable blanket at bedtime is not recommended because any loose bedding can increase the risk of suffocation or overheating. Instead, wearable sleep sacks or appropriate clothing should be used to keep the infant warm safely without loose coverings in the crib.

Atraumatic care during infant immunization focuses on minimizing physical pain and psychological distress while ensuring safe vaccine administration. Infants at 3 months of age experience procedural pain intensely, so nurses use evidence-based comfort measures alongside proper injection technique. Non-pharmacological interventions such as oral sucrose, breastfeeding, and pacifiers are effective in reducing pain perception during short procedures like immunizations. The goal is to promote comfort, reduce stress responses, and support positive healthcare experiences.

Rationale:
A. Using a 20-gauge needle is inappropriate because it is too large for infant intramuscular injections and would increase tissue trauma and pain. Infants typically require smaller gauge needles (e.g., 22–25 gauge) to ensure proper delivery of vaccines with minimal discomfort and tissue injury.

B. Applying eutectic mixture of local anesthetics (EMLA) immediately before injections is ineffective because EMLA requires time (about 30–60 minutes) to achieve adequate dermal anesthesia. Immediate application does not provide pain relief during the procedure, making it unsuitable for short-notice immunization appointments.

C. Injecting immunizations into the deltoid muscle is incorrect for a 3-month-old infant because the deltoid is not sufficiently developed at this age. The recommended site for infants is the vastus lateralis muscle in the anterolateral thigh, which provides a larger, safer muscle mass for intramuscular injections.

D. Providing a pacifier coated with oral sucrose solution is appropriate because sucrose activates endogenous opioid pathways, reducing pain perception in infants during minor procedures. Combined with non-nutritive sucking, it provides effective, quick-acting analgesia and supports atraumatic care during immunization administration.
