A nurse is caring for a client who is receiving positive end-expiratory pressure (PEEP) via mechanical ventilation. The nurse should monitor the client for which of the following adverse effects of PEEP?

A. A client who has cellulitis and is receiving oral antibiotics every 8 hr has a mild to moderate infection that can be managed at home with proper wound care and medication adherence. The client does not require hospitalization unless there are signs of systemic infection or complications.

B. A client who is postoperative following an upper endoscopy procedure and is alert but does not have a gag reflex has a high risk of aspiration and airway obstruction due to impaired swallowing function. The client requires close monitoring and intervention until the gag reflex returns, which can take several hours or longer depending on the type and amount of anesthesia used.

C. A mother and their newborn 12 hr postdelivery have not completed the minimum recommended stay of 24 to 48 hours for uncomplicated vaginal deliveries or 72 to 96 hours for cesarean deliveries, according to the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists. The mother and their newborn require assessment, education, support, and follow-up care to ensure their health and well-being.

D. A client who has lower extremity weakness and is newly admitted for observation has an undiagnosed condition that could indicate a serious neurological or vascular problem, such as stroke, spinal cord injury, or peripheral artery disease. The client requires diagnostic testing, evaluation, treatment, and rehabilitation to prevent further deterioration or complications.

A. Incorrect. Maintaining a flexible daily schedule for the child may increase their anxiety and confusion, as they may have difficulty adapting to changes in routine and expectations. The nurse should advise the parents to establish a consistent and structured schedule for the child, with clear rules and boundaries.

B. Correct. Using a reward system to modify the child's behavior is an effective strategy to reinforce positive behaviors and reduce negative ones. The nurse should help the parents identify specific and measurable goals for the child, and provide them with praise, tokens, or privileges when they achieve them.

C. Incorrect. Providing a variety of family members to care for the child may overwhelm them and impair their social skills development, as they may have difficulty forming attachments and communicating with different people. The nurse should encourage the parents to select one or two primary caregivers for the child, who can provide them with consistent and supportive interactions.

D. Incorrect. Administering alprazolam as needed to reduce the child's anxiety is not recommended, as it may cause adverse effects such as sedation, dependence, or withdrawal symptoms. The nurse should educate the parents about nonpharmacological interventions for anxiety, such as relaxation techniques, cognitive behavioral therapy, or social skills training.
