Which statement is true concerning osteogenesis imperfecta (OI)?
OI is easily treated
With a later onset, the disease usually runs a more difficult course
Braces and PT exercises are of no therapeutic value
OI is an inherited disorder
The Correct Answer is D
Choice A: OI is Easily Treated
Osteogenesis imperfecta (OI) is not easily treated. It is a genetic disorder characterized by fragile bones that break easily. While there are treatments available to manage symptoms and improve quality of life, there is no cure for OI1. Treatments include medications to strengthen bones, physical therapy, and surgical procedures.
Choice B: With a Later Onset, the Disease Usually Runs a More Difficult Course
The severity of osteogenesis imperfecta can vary widely, but it is not necessarily true that a later onset leads to a more difficult course. The course of the disease depends on the type of OI and the specific genetic mutation involved. Some types of OI are more severe and present earlier in life, while others are milder and may not be diagnosed until later.
Choice C: Braces and PT Exercises are of No Therapeutic Value
This statement is incorrect. Braces and physical therapy (PT) exercises are valuable in managing osteogenesis imperfecta. Physical therapy helps in building muscle strength, improving joint movement, and preventing fractures. Braces can provide support for weak muscles, decrease pain, and keep joints properly aligned.
Choice D: OI is an Inherited Disorder
This statement is true. Osteogenesis imperfecta is a genetic disorder that is usually inherited in an autosomal dominant pattern. This means that a person only needs one copy of the defective gene from one parent to inherit the disorder. In some cases, OI can also occur due to a spontaneous mutation.

Correct Answer is C
Explanation
Choice A: Apply antibiotic ointment to pin sites daily
Applying antibiotic ointment to pin sites daily is not relevant in the context of Buck extension traction. Buck’s traction is a type of skin traction, which does not involve pins or pin sites. Pin site care is typically associated with skeletal traction, where pins are inserted directly into the bone.
Choice B: Remove the traction boot during baths
Removing the traction boot during baths is not recommended. The traction boot should remain in place to maintain the alignment and immobilization of the affected limb. Removing the boot can disrupt the traction and potentially worsen the condition.
Choice C: Assess neurovascular status every 2 hours
Assessing neurovascular status every 2 hours is crucial for a child in Buck extension traction. This involves checking the circulation, sensation, and movement of the affected limb to ensure there are no complications such as nerve damage or impaired blood flow. Regular neurovascular assessments help in early detection and prevention of complications.
Choice D: Reduce fluid intake
Reducing fluid intake is not a standard care practice for a child in Buck extension traction. Adequate hydration is important for overall health and recovery. There is no indication that fluid intake should be restricted in this scenario.
Correct Answer is ["A","B","C","D","E","F","G","H","I"]
Explanation
The correct answer is
A. Unable to roll over back to front
B. Head lag
C. Feeding difficulties
D. Floppy posture
E. Arms are stiff
F. Does not smile
G. Unable to sit without support
H. Irritable and cries often
I. Unable to pass an object between hands
Choice A reason
Unable to roll over back to front: At 3 months, infants typically start to develop the ability to roll over from their stomach to their back. Rolling over from back to front usually occurs later, around 4 to 6 months. However, the inability to roll over at all by 3 months could indicate developmental delays or muscle weakness, which requires follow-up.
Choice B Reason
Head lag: By 3 months, infants should have enough neck muscle strength to hold their head up when pulled to a sitting position. Persistent head lag at this age can be a sign of developmental delay or neuromuscular disorders, necessitating further evaluation.
Choice C Reason
Feeding difficulties: Infants should be able to suck and swallow effectively by 3 months. Feeding difficulties can lead to inadequate nutrition and growth, and may indicate underlying issues such as gastrointestinal problems or neurological disorders. This requires prompt attention and intervention.
Choice D Reason
Floppy posture: A 3-month-old should start to show more control over their body movements and have a more stable posture. Floppy posture, also known as hypotonia, can be a sign of various conditions, including genetic disorders, muscle diseases, or central nervous system issues. It is important to investigate the cause of hypotonia.
Choice E Reason
Arms are stiff: Stiffness in the arms, or hypertonia, can indicate neurological problems such as cerebral palsy or other motor disorders. It is crucial to assess the underlying cause of increased muscle tone and provide appropriate interventions.
Choice F Reason
Does not smile: Social smiling typically begins around 6 to 8 weeks of age. If a 3-month-old does not smile, it could be a sign of developmental delay, visual impairment, or other social and emotional issues. This warrants further assessment to determine the cause.
Choice G Reason
Unable to sit without support: While sitting without support is not expected until around 6 months, the inability to show any signs of trying to sit or maintain a sitting position with support at 3 months could indicate developmental delays. This should be monitored and addressed if necessary.
Choice H Reason
Irritable and cries often: Excessive irritability and frequent crying can be signs of discomfort, pain, or underlying medical conditions such as infections, gastrointestinal issues, or neurological problems. It is important to identify and address the cause of the infant’s distress.
Choice I Reason
Unable to pass an object between hands: By 3 months, infants should start to develop hand-eye coordination and the ability to grasp objects. The inability to pass an object between hands may indicate developmental delays or motor skill issues, which require further evaluation.
