The nurse is teaching family members of a child newly diagnosed with muscular dystrophy about early signs.
The nurse knows that teaching was successful when a parent states that which of the following signs may indicate the condition early?
High fevers and tiredness.
Increased muscle strength.
Respiratory infections and obesity.
Difficulty climbing stairs.
The Correct Answer is D
Difficulty climbing stairs is an early sign of muscular dystrophy.
This is because the condition causes progressive muscle weakness, which can make it difficult for the child to perform physical activities that require muscle strength.

Choice A is not the best answer because high fevers and tiredness are not specific to muscular dystrophy and can be caused by many other conditions.
Choice B is not the best answer because muscular dystrophy causes muscle weakness, not increased muscle strength.
Choice C is not the best answer because respiratory infections and obesity are not specific to muscular dystrophy and can be caused by many other conditions.

Correct Answer is B
Explanation
Radiographs are vital to the diagnosis of Legg-Calve-Perthes disease.
Initial X-rays might look normal because it can take one to two months after symptoms begin for the changes associated with Legg-Calve-Perthes disease to become evident on X-rays.
The doctor will likely recommend several X-rays over time, to track the progression of the disease.

Bone biopsy is not a diagnostic procedure for Legg-Calve-Perthes disease.
MRI can visualize bone damage caused by Legg-Calve-Perthes disease more clearly than X-rays can but are not always necessary.
Genetic testing is not a diagnostic procedure for Legg-Calve-Perthes disease.
Correct Answer is B
Explanation
A. Lateral incisors are present:At 6 months, infants typically begin teething, but the lateral incisors usually do not appear until around 9 to 13 months. The first teeth to emerge are usually the lower central incisors.
B. Posterior fontanel is closed:The posterior fontanel, or the soft spot at the back of the baby's head, typically closes by 2 to 3 months of age. Therefore, it is expected to be closed by the time the infant is 6 months old.
C. Infant's birth weight is tripled:By 6 months, infants generally double their birth weight. Tripling of birth weight is more commonly expected by the end of the first year.
D. Infant sits well without support:Most infants begin to sit without support around 7 to 9 months. At 6 months, they may sit with some support but are not yet expected to sit well independently.
