The practical nurse (PN) is reviewing education for the parents of an infant with developmental dysplasia of the hip about dynamic splinting.
Which information should the PN reinforce about the purpose of this treatment?
Promotes range-of-motion.
Increases extension.
Maintains abduction.
Provides immobilization.
The Correct Answer is C
Choice A rationale
Promoting range-of-motion is typically achieved through exercises and movement. Dynamic splinting aims to maintain a specific joint position rather than actively increasing range of motion, which might be counterproductive to hip stability in developmental dysplasia.
Choice B rationale
Increasing extension would involve straightening the hip joint. In developmental dysplasia of the hip, the goal of treatment is to maintain the femoral head within the acetabulum, which often requires a flexed and abducted position, not extension.
Choice C rationale
Maintaining abduction is the primary purpose of dynamic splinting in developmental dysplasia of the hip. Abduction helps to seat the femoral head deeply into the acetabulum, promoting proper hip development and stability by stimulating acetabular ossification.
Choice D rationale
Providing immobilization implies completely restricting movement. Dynamic splinting, like the Pavlik harness, allows some movement while maintaining the abduction, flexion, and external rotation necessary for proper hip development. Full immobilization is typically not the goal for developmental dysplasia.

Correct Answer is C
Explanation
Choice A rationale
While preventing further disability is a component of care for some progressive conditions, it is not the primary overarching goal for all developmental disabilities. Many developmental disabilities are static and non-progressive, meaning their primary impact is on functional limitations rather than ongoing deterioration. The focus shifts to maximizing existing abilities and potential rather than preventing progression.
Choice B rationale
Meeting rehabilitation needs is a critical aspect of care for children with developmental disabilities, focusing on improving specific skills and functions. However, rehabilitation is a means to an end. The ultimate objective extends beyond just addressing deficits to encompassing the child's holistic development and empowering them to achieve their highest possible level of independence and functioning.
Choice C rationale
The primary goal for a child with a developmental disability is to help them achieve their maximum potential. This encompasses a holistic approach, focusing on enhancing their cognitive, physical, social, emotional, and adaptive skills. It aims to foster independence, improve quality of life, and integrate them into society as much as possible, recognizing their unique strengths and capabilities.
Choice D rationale
Promoting the child's social acceptability, while important for their well-being and integration, is a secondary outcome rather than the primary goal of treatment. The main focus is on the child's individual development and functional abilities. Enhanced social acceptability often naturally follows when a child achieves greater independence and participation in various life domains.
Correct Answer is D
Explanation
Choice A rationale
Cheese is a good source of calcium and protein, but it is not a primary source of iron. Iron is essential for hemoglobin synthesis, and the client's hemoglobin and hematocrit levels are below normal ranges [Hemoglobin, pregnant female > 11 g/dL ( > 110 g/L); Hematocrit, pregnant female > 33% ( > 0.33 volume fraction)], indicating iron deficiency anemia.
Choice B rationale
Cauliflower is a cruciferous vegetable rich in vitamin C and fiber, but its iron content is relatively low. While vitamin C aids in iron absorption, cauliflower itself does not provide a significant amount of dietary iron to effectively address the client's anemic status.
Choice C rationale
Carrots are well-known for their beta-carotene content, a precursor to vitamin A, and provide fiber. However, carrots are not a significant source of iron. To combat iron deficiency anemia during pregnancy, foods rich in heme iron or non-heme iron with good bioavailability are required.
Choice D rationale
Chicken, particularly the dark meat, is a good source of heme iron, which is more readily absorbed by the body compared to non-heme iron found in plant-based foods. Given the client's anemic status, increasing dietary intake of iron-rich foods like chicken is crucial for improving hemoglobin and hematocrit levels.
