What age group should be routinely screened for scoliosis?
Newborn
Young teens
Older adult
None of the above
The Correct Answer is B
Choice A reason: Newborns are not routinely screened for scoliosis, as it typically develops later. Congenital scoliosis may be assessed in infants with specific risk factors, but routine screening occurs in adolescence when idiopathic scoliosis emerges, making this choice incorrect.
Choice B reason: Young teens, particularly ages 10–15, are routinely screened for scoliosis, as idiopathic scoliosis commonly appears during the growth spurt of puberty. Early detection via physical exams allows for interventions like bracing to prevent curve progression, making this the correct choice.
Choice C reason: Older adults are not routinely screened for scoliosis, as most cases are degenerative or pre-existing. Screening focuses on adolescents when curves are most likely to develop. In adults, scoliosis is monitored if symptomatic, making this choice incorrect.
Choice D reason: Routine scoliosis screening is recommended for young teens, not none of the above. Guidelines from organizations like the American Academy of Pediatrics emphasize screening during adolescence to catch idiopathic scoliosis early, making this choice incorrect.

Correct Answer is C
Explanation
Choice A reason: A dose of 0.2 g (200 mg) requires 2 capsules of 100 mg each, not 3. Administering 3 capsules would deliver 300 mg, exceeding the prescribed dose, potentially causing toxicity due to phenytoin’s narrow therapeutic index, making this choice incorrect.
Choice B reason: “None of the above” is incorrect, as the calculation for 0.2 g (200 mg) divided by 100 mg per capsule yields exactly 2 capsules. A precise dose is possible with the available capsules, so this option does not apply to the scenario.
Choice C reason: Converting 0.2 g to 200 mg and dividing by 100 mg per capsule results in 2 capsules per dose. This matches the prescription exactly, ensuring therapeutic levels of phenytoin, an anticonvulsant, are administered safely, making this the correct choice.
Choice D reason: One 100 mg capsule provides only half the prescribed 0.2 g (200 mg) dose. This underdosing could lead to subtherapeutic phenytoin levels, risking seizures in a patient dependent on this anticonvulsant, making this choice incorrect.
Correct Answer is D
Explanation
Choice A reason: An open fracture involves a break in the skin, allowing bone exposure to the external environment, increasing infection risk. This is the opposite of a fracture contained within the skin, as described in the question, making this choice incorrect for defining a contained fracture.
Choice B reason: A complete fracture refers to a bone broken into two or more separate pieces, regardless of skin involvement. It does not specifically indicate whether the fracture is contained within the skin, as it focuses on bone separation rather than soft tissue status, making it incorrect.
Choice C reason: A compression fracture involves the collapse of a vertebra, typically in the spine, often due to osteoporosis. It does not inherently specify whether the skin is intact. The term is too specific to spinal injuries and not general enough for the question’s description, making it incorrect.
Choice D reason: A closed fracture is a bone break where the skin remains intact, with no external wound. This matches the question’s description of a fracture contained within the skin. It is the standard term used in medical practice to describe such injuries, making it the correct choice.
