At what degree of scoliosis curvature is a brace typically recommended for treatment in adolescents?
10 degrees.
48 degrees.
30 degrees.
20 degrees.
The Correct Answer is C
Choice A rationale
A 10-degree scoliosis curvature is considered a very mild curve and often falls within the normal range or represents postural asymmetry. At this degree, bracing is not typically recommended; instead, observation and regular monitoring are usually sufficient to track progression, as spontaneous resolution is possible.
Choice B rationale
A 48-degree scoliosis curvature is a significant and severe curve that typically indicates advanced scoliosis. At this degree, bracing alone is often insufficient to correct the curve, and surgical intervention, such as spinal fusion, is usually recommended to prevent further progression and mitigate severe complications.
Choice C rationale
A 30-degree scoliosis curvature in adolescents is a threshold where a brace is typically recommended. This degree of curvature indicates a progressive curve that is likely to worsen if left untreated. Bracing aims to halt the progression of the curve during the adolescent growth spurt, preventing the need for surgery.
Choice D rationale
A 20-degree scoliosis curvature is a moderate curve. While it is more significant than a 10-degree curve, it is often still managed with close observation and monitoring, especially if the adolescent has significant growth remaining. Bracing might be considered, but 30 degrees is a more common guideline for initiation.

Correct Answer is D
Explanation
Choice A rationale
Increased energy levels are typically not a symptom of depression in younger children. Instead, depression often manifests as a reduction in energy, leading to fatigue, lethargy, and a general lack of motivation or interest in previously enjoyed activities. This shift in energy levels can significantly impact daily functioning and play.
Choice B rationale
Decreased irritability is not a common symptom of depression in younger children. On the contrary, young children experiencing depression often exhibit heightened irritability, anger outbursts, and defiance as external manifestations of their internal distress and sadness. This can lead to difficulties in social interactions.
Choice C rationale
Improved concentration is not a symptom of depression; rather, impaired concentration and difficulty focusing are hallmark signs. Children with depression often struggle with academic tasks, forgetfulness, and an inability to sustain attention, leading to a decline in school performance and frustration.
Choice D rationale
Changes in appetite and sleep patterns are common neurovegetative symptoms of depression across all age groups, including younger children. This can present as increased or decreased appetite, leading to weight changes, and difficulties with sleep, such as insomnia, hypersomnia, or frequent awakenings, disrupting daily routines.
Correct Answer is D
Explanation
Choice A rationale
An alpha-fetoprotein (AFP) test is a blood test that measures the levels of AFP in the maternal serum. This test does not require any specific dietary restrictions, such as fasting. Therefore, advising the client to abstain from food or drink for 8 hours before the test is not based on physiological necessity for accurate AFP measurement.
Choice B rationale
Test results are influenced by various factors, including gestational age, multiple pregnancies, and certain fetal anomalies. While chronic illnesses can impact overall health, they do not directly determine the outcome of an AFP screening test, which primarily assesses the risk of neural tube defects or chromosomal abnormalities.
Choice C rationale
An AFP test is a simple blood draw and is not an invasive procedure. Therefore, there is no physiological need for bed rest following the test. Clients can resume their normal activities immediately after the blood sample is collected, as there are no associated post-procedure complications requiring immobility.
Choice D rationale
The AFP test is a screening tool, meaning it identifies individuals who may be at an increased risk for certain conditions, such as neural tube defects or Down syndrome. It does not provide a definitive diagnosis. Abnormal screening results necessitate further diagnostic testing, such as amniocentesis or high-resolution ultrasound, for confirmation.
