A 1-month-old infant is seen in a clinic and is diagnosed with developmental dysplasia of the hip (DDH). On assessment, the nurse understands that which finding would be noted in this condition?
Limited range of motion in the affected hip
Symmetry of the gluteal skinfolds when the infant is placed prone and the legs are extended
Negative Barlow test
Unaffected leg is pale and cool
The Correct Answer is A
A. Developmental dysplasia of the hip (DDH) often presents with a limited range of motion in the affected hip, particularly in abduction.
B. Asymmetry of the gluteal skinfolds, not symmetry, is a typical finding in DDH. This asymmetry is due to the improper alignment of the hip joint.
C. A positive Barlow test, where the hip can be dislocated by adduction and posterior pressure, is indicative of DDH. A negative Barlow test would suggest the absence of DDH.
D. A pale and cool leg is not a common finding in DDH. This would be more indicative of a circulatory problem, not hip dysplasia.

Correct Answer is D
Explanation
A. While monitoring blood pressure is important, a blood pressure of 98/62 mm Hg may not immediately warrant notification unless there are signs of hypotension or other symptoms. The focus should be on careful management of fluid and electrolytes.
B. In cases of acute renal failure, potassium levels can become elevated due to impaired renal function. Therefore, IV fluids should typically be low in potassium to prevent hyperkalemia.
C. In acute renal failure, a diet high in protein and sodium is not recommended. Instead, dietary restrictions are usually advised to manage waste products and fluid balance.
D. Administering IV fluids slowly helps to prevent fluid overload, which is crucial in managing renal failure and maintaining hemodynamic stability.
Correct Answer is B
Explanation
A. Mild illnesses like nasopharyngitis (a common cold) do not typically contraindicate vaccination, so there is no need to delay immunization.
B. It is essential to evaluate for allergies to vaccine components, such as gelatin or neomycin, which could contraindicate the administration of the varicella vaccine.
C. The first dose of the varicella vaccine is recommended at 12-15 months of age, not at 4 years of age, so it is appropriate to administer it during this well-check.
D. The varicella vaccine is administered subcutaneously, not intramuscularly, so this is not the correct route for administration.
