Limping boys of four and thirteen compared, exam and causes both adjusted for age, including why the teenager's knee pain sends the examination to his hip. Searches like "nu 552 unit 9 assignment example", "nu552 unit 9 sample" and "nu552 unit 9 example" land here.
What a finished NU552 Unit 9 lifespan assessment comparison looks like
About five pages: a comparison table and two short narratives. The table's rows are exam steps, from watching the child play or walk to hip rotation, log roll, knee palpation and temperature; its columns give the four-year-old's version, the teenager's, and the reason each differs. Below it sit two ranked differentials. For the younger boy, transient synovitis is most likely and septic arthritis most dangerous, with Perthes disease and an occult fracture lower. Kocher's four criteria are listed, noting that the original study's probabilities fell in later validation cohorts. For the older boy, slipped capital femoral epiphysis leads on danger and, given obligatory external rotation on hip flexion, on likelihood too, above Osgood-Schlatter disease and patellofemoral pain. What both exams share closes the paper.
How a NU552 Unit 9 example is structured
Age is treated as a variable that changes both the examination and the likely diagnoses, and the paper keeps those halves distinct. The exam table explains each adjustment by development or anatomy: a four-year-old cannot localize pain reliably and is examined through play; a thirteen-year-old can describe pain but may feel hip pathology in the knee, referred along the obturator nerve. Both differentials use the same likelihood and danger columns, making the contrast easy to read. Prediction rules are cited with their limits. The teenager's case makes the sharpest point: an exam confined to the painful knee would have missed the leading diagnosis, and the table shows hip rotation as the step that found it. Its last lines note what does not change with age: fever and refusal to bear weight always raise concern for infection.
One complaint, two ages
Both boys limp, and the opening states that the same word covers different anatomy, different causes and different examinations. That framing makes the comparison the argument rather than two unrelated cases.
Exam steps that change
Play-based observation, the log roll and hip rotation shift in emphasis and technique between the two ages. Each row gives a reason grounded in development or anatomy for the difference.
A prediction rule with caveats
Kocher's criteria for septic arthritis appear with original and validation figures in brackets. The rule was derived in one population and performed less well elsewhere, a limit stated outright.
Knee pain, hip cause
Referred pain explains why the teenager's exam turned to the hip. Obligatory external rotation during hip flexion is recorded, and slipped epiphysis goes first on both likelihood and danger.
What stays the same
Fever with refusal to bear weight raises infection at any age. Only a few findings keep their meaning across the lifespan, and the paper names them.
Where marks go in NU552 Unit 9
The comparison is graded on whether age reshapes the examination as well as the reasoning. A paper that adjusts technique for the younger child but then uses one differential for both boys does half the job. Differentials that differ while the exam stays identical miss the other half. Examining only the knee in a limping adolescent with knee pain is the specific error this kind of case is built to catch, and instructors look for the hip exam. Prediction rules cited as definitive, without their validation limits, lose precision. Differentials ranked without saying whether likelihood or danger set the order draw familiar comments. Uncited developmental claims, no statement of which findings mean the same at every age, and tables listing steps without reasons shave off a little more.

NU552 Unit 9 questions, answered
Can the comparison be between an adult and an older adult?
Yes, and the method is unchanged. Comparing abdominal pain in a thirty-year-old and an eighty-year-old, for example, would adjust the exam for blunted tenderness in late life and move vascular causes up the differential. The sample adjusts both the examination and the diagnoses for whatever ages the prompt pairs, giving reasons.
Are clinical prediction rules expected here?
Where a well-known rule applies to the complaint, citing it usually strengthens the paper. The sample uses Kocher's criteria for the younger child and states their limits. A rule quoted without its derivation population or validation performance tends to draw comments in reasoning courses, so the caveat carries equal weight with the rule itself.
Should both cases get equal length?
Roughly, though the comparison table does most of the work. The sample gives each boy a short narrative and a ranked differential of similar length, then spends its analytical space on the contrast. A paper treating one age in depth and the other in a paragraph reads as a single case with an appendix.
