The pediatric nurse is caring for a group of 4-year-old clients with various diagnoses. The child being treated for which diagnosis will most need help understanding what is happening to him or her?

Choice A reason: Walking then running is a gross motor sequence, not proximodistal, which progresses from central to peripheral control. Arm waving to foot grasping shows this pattern, making this incorrect, as it does not illustrate the infant’s proximodistal development in the instructor’s class.

Choice B reason: Rolling over precedes eye tracking, but proximodistal development involves motor control from trunk to extremities. Arm waving to foot grasping better illustrates this, making this incorrect, as it does not reflect the central-to-peripheral progression of infant motor development in the lesson.

Choice C reason: Imitating sounds to speaking is linguistic, not proximodistal, which focuses on motor control from core to limbs. Arm waving to foot grasping demonstrates this pattern, making this incorrect, as it does not represent the physical developmental sequence taught in the infant development class.

Choice D reason: Kicking and arm waving involve trunk and proximal muscles, while grasping the foot uses distal control, illustrating proximodistal development. Students choosing this show understanding, aligning with infant motor development principles, making it the correct example for a successful class on infant development.

Choice A reason: Rheumatic fever follows streptococcal infections but typically presents with joint pain or carditis, not puffy eyes or abnormal urine. Glomerulonephritis matches the post-infectious symptoms, making this incorrect, as it does not align with the child’s clinical presentation after ear infections.

Choice B reason: Lipoid nephrosis causes edema but lacks a clear link to recent infections or hematuria. Acute glomerulonephritis better explains the symptoms post-ear infection, making this less fitting and incorrect for the suspected condition based on the child’s reported signs and history.

Choice C reason: Urinary tract infections cause dysuria or frequency, not typically puffy eyes or hematuria post-infection. Glomerulonephritis aligns with the streptococcal history and symptoms, making this incorrect compared to the condition suspected based on the child’s clinical presentation to the nurse.

Choice D reason: Acute glomerulonephritis, often post-streptococcal from ear infections, causes hematuria (“funny” urine), periorbital edema (puffy eyes), and headache. This aligns with pediatric nephrology evidence, making it the correct condition the nurse suspects, prompting immediate evaluation by a care provider for the child.
