The client is 16 weeks pregnant.
If the pregnancy is progressing as expected, where would the healthcare provider be able to palpate the uterine fundus?
At the umbilicus.
The uterine fundus would not be palpable at 16 weeks.
Halfway between the pubic bone and the umbilicus.
Just above the pubic bone.
The Correct Answer is C
Choice A rationale
At 16 weeks of gestation, the uterine fundus has not yet reached the umbilicus. The umbilicus is typically reached around 20 weeks of gestation. Palpating the fundus at the umbilicus at 16 weeks would suggest a discrepancy in gestational age or a potential complication such as polyhydramnios or multiple gestation, warranting further investigation.
Choice B rationale
The uterine fundus is palpable at 16 weeks of gestation. By this stage, the uterus has grown significantly and ascended out of the pelvis, making it accessible to abdominal palpation. Failure to palpate the fundus at this stage could indicate an inaccurate gestational age, ectopic pregnancy, or other uterine abnormalities, requiring clinical correlation.
Choice C rationale
At 16 weeks of gestation, the uterine fundus is typically palpable approximately halfway between the symphysis pubis and the umbilicus. This anatomical landmark serves as a reliable indicator of gestational age during the second trimester. The fundus ascends by approximately 1 cm per week after 12 weeks of gestation, providing a consistent growth pattern.
Choice D rationale
At 16 weeks of gestation, the uterine fundus is well above the pubic bone. It typically becomes palpable just above the pubic bone around 12 to 14 weeks of gestation as it rises out of the pelvic cavity. Finding the fundus only just above the pubic bone at 16 weeks would suggest a lag in uterine growth or an inaccurate gestational age assessment.

Correct Answer is C
Explanation
Choice A rationale
Phalen's Maneuver is a diagnostic test used to assess for carpal tunnel syndrome. It involves sustained wrist flexion, which increases pressure within the carpal tunnel, exacerbating median nerve compression symptoms such as tingling and numbness in the hand. This test is unrelated to spinal curvature assessment.
Choice B rationale
The Romberg Test evaluates proprioception and cerebellar function, assessing a person's ability to maintain balance with eyes closed. It helps identify neurological deficits affecting balance and coordination but does not involve direct assessment of spinal alignment or curvature, thus it is not used for scoliosis screening.
Choice C rationale
Adam's Forward Bend Test is the primary method used during scoliosis screening. It involves the individual bending forward at the waist with feet together and arms hanging loosely. This position makes any asymmetry or prominence of the ribs or spine more visible, indicating a potential spinal curvature.
Choice D rationale
Lasegue's Sign Test, also known as the Straight Leg Raise Test, is used to detect nerve root irritation, typically associated with sciatica or herniated lumbar discs. It involves passively raising the straightened leg of a supine patient to elicit pain, indicating nerve compression. This test is not for scoliosis screening.
Correct Answer is C
Explanation
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.
