Which of the following actions should the nurse plan to take? Select the actions the nurse should plan to take.

Choice A rationale: Yellow nasal discharge in a toddler with acute nephrotic syndrome signifies a potential upper respiratory tract infection, which is critically important. Children with nephrotic syndrome are highly susceptible to infections due to significant urinary loss of immunoglobulins, leading to an immunocompromised state. Furthermore, corticosteroid treatments, often prescribed for nephrotic syndrome, suppress the immune system. An infection can precipitate a relapse of the syndrome, lead to severe complications like peritonitis or sepsis, and requires prompt evaluation and potentially antibiotic therapy to prevent life-threatening outcomes.

Choice B rationale: Poor appetite is a non-specific symptom in toddlers with nephrotic syndrome and does not typically indicate an immediate, life-threatening complication. It can be attributed to generalized malaise, abdominal discomfort due to ascites, or even side effects of medications such as corticosteroids. While important to monitor for nutritional status and overall well-being, it does not carry the same urgency as signs of infection, which can rapidly lead to severe health deterioration in an immunocompromised child.

Choice C rationale: Facial edema is a cardinal clinical manifestation of acute nephrotic syndrome, resulting from profound hypoalbuminemia. Reduced plasma oncotic pressure causes fluid to shift from the intravascular space into the interstitial space, leading to generalized edema, often prominently in the face. This finding is expected and indicates the disease process itself, rather than an acute, unexpected complication requiring immediate reporting, unless there is a sudden, significant worsening or associated respiratory compromise.

Choice D rationale: Irritability in a toddler can be a manifestation of general discomfort, illness, or even a side effect of corticosteroid therapy, which can cause mood disturbances and behavioral changes. While it warrants assessment to identify the underlying cause, irritability is a non-specific symptom and does not directly indicate an urgent, life-threatening complication of nephrotic syndrome requiring immediate medical intervention, unlike the signs of an acute infection in an immunocompromised child.

The correct answer is Choice A.

Choice A rationale: Encouraging the infant to stand in the crib while in a cast for developmental dysplasia of the hip (DDH) supports gross motor development and maintains neuromuscular stimulation. Standing promotes proprioceptive input, strengthens postural muscles, and supports bone mineralization through weight-bearing. Infants in hip spica casts or orthotic devices can safely stand with supervision, preserving developmental milestones. Normal serum calcium ranges from 8.5 to 10.5 mg/dL, and mechanical loading enhances osteoblastic activity and skeletal growth.

Choice B rationale: While electronic toys offer sensory stimulation, they do not adequately support gross motor development in infants with DDH. At 10 months, infants require opportunities for vertical positioning and weight-bearing to stimulate vestibular and musculoskeletal systems. Passive play with electronic toys may delay motor milestones such as cruising and standing. Developmental progress depends on integrated sensory-motor experiences, and reliance on sedentary toys may limit engagement of core and lower limb musculature.

Choice C rationale: Latex balloons pose a significant safety hazard due to the risk of aspiration and suffocation. When burst, latex fragments can occlude the airway, especially in infants with underdeveloped protective reflexes. The tracheal diameter in infants averages 4 to 5 mm, making obstruction by balloon fragments potentially fatal. Additionally, latex exposure may trigger allergic reactions, particularly in atopic individuals. The American Academy of Pediatrics strongly advises against latex balloon use in children under 8 years.

Choice D rationale: Prompt diaper changes are essential for skin integrity, especially under a cast where moisture retention can lead to maceration and infection. However, this action does not directly promote growth and development. It is a hygiene measure that prevents irritant contact dermatitis and secondary infections such as Candida albicans. Normal skin pH ranges from 4.5 to 5.5, and prolonged exposure to urine and feces elevates pH, disrupting the acid mantle. While necessary, it lacks developmental stimulation.
