A nurse is assisting with the care of a client who has delirium. The client is disoriented and restless. Which of the following conditions should the nurse identify as a risk factor for delirium?

Choice A reason: Shoulder harnesses at shoulder level secure the infant, distributing crash forces evenly. Scientifically, this aligns with safety standards, preventing spinal injury by stabilizing the torso, a critical car seat feature per biomechanical crash studies for optimal protection.

Choice B reason: A cushion under the head risks airway obstruction or spinal misalignment in crashes. Scientifically, added padding alters manufacturer design, increasing injury risk, as car seats are engineered for direct fit without extras per safety regulations.

Choice C reason: A 90-degree angle is upright, risking airway collapse in newborns with weak necks. Scientifically, a 30-45-degree recline supports breathing and spinal alignment, making this unsafe per pediatric and crash safety evidence.

Choice D reason: Airbags in the front seat can fatally injure infants in rear-facing seats via rapid inflation. Scientifically, back-seat placement avoids this, as airbag force exceeds infant tolerance, contradicting safety mandates for car seat positioning.

Choice A reason: Counterpressure helps back labor pain, not cesarean incision pain. It targets muscle tension, not surgical site discomfort, which stems from tissue trauma. For a day-old cesarean, this misaligns with pain source, lacking scientific support for reducing abdominal strain during position changes post-surgery.

Choice B reason: Limiting position changes reduces mobility, risking complications like thrombosis or stiffness post-cesarean. Movement aids recovery, and pain management should facilitate, not hinder, it. This advice contradicts evidence-based practice promoting early ambulation, making it an ineffective and potentially harmful nonpharmacological strategy.

Choice C reason: Splinting the incision with a pillow supports the abdominal wall, reducing strain on sutures during movement. This decreases pain from muscle stretching post-cesarean, aligning with scientific principles of mechanical support, making it an effective, evidence-based nonpharmacological method to manage discomfort safely.

Choice D reason: Patterned breathing aids labor or anxiety, not surgical pain. It distracts from discomfort but does not address physical strain on the cesarean incision during position changes. Lacking direct mechanical relief, it’s less effective scientifically compared to splinting for this specific postoperative pain context.
