A composite six-year-old's sandpaper rash, a positive rapid strep test, weight-based [amoxicillin] capped at its maximum and a school return date make up NU580's Unit 9 case. Searches like "nu 580 unit 9 assignment example", "nu580 unit 9 sample" and "nu580 unit 9 example" land here.
What a finished NU580 Unit 9 acute illness case study looks like
Four pages in case study form: presentation, differential, diagnostics, management and follow-up. The presentation gives the history, two days of sore throat and a rash that began on her neck, then the examination: tonsillar exudate, a red tongue with prominent papillae, a blanching sandpaper rash heavier in the skin folds, and no cough. The differential sets scarlet fever beside a viral exanthem, a drug rash and, briefly, Kawasaki disease, explaining why two days of fever keeps the last one low. Diagnostics record the rapid antigen detection test as positive, so no backup culture is needed. Management calculates [amoxicillin] at [50 mg/kg] once daily for her [21] kg, which reaches [1050 mg] and is capped at [1000 mg], for [10] days. Follow-up covers school return, household symptoms and the rare complications to watch.
How a NU580 Unit 9 example is structured
Age runs through every section. The differential explains that group A streptococcal pharyngitis peaks in school-age children and is uncommon under three, which is why the 2012 IDSA guideline discourages routine testing in the youngest children. The diagnostics section adds that clinical scores alone are not enough to diagnose strep in children, and that a negative rapid test in a child would normally be backed by a throat culture. Management is written as a calculation with every figure shown, since the weight-based dose overtaking the maximum is the teaching point: the cap, not the formula, sets her dose. An alternative for penicillin allergy is named with its own bracketed regimen. The follow-up section cites the AAP Red Book on school return and lists acute rheumatic fever and peritonsillar abscess as complications prompting reassessment.
A rash read with the throat
The sandpaper texture, deeper color in the elbow creases and a flushed face with pale skin around the mouth are described as the pattern of scarlet fever, and the case ties the rash to the streptococcal toxin rather than treating it as a separate problem.
Age decides whether to test
At six she sits in the peak age range for streptococcal pharyngitis. The case contrasts her with a hypothetical two-year-old, whose sore throat would rarely justify testing because the disease and its complications are uncommon at that age.
Where the formula meets the cap
Fifty milligrams per kilogram for her [21] kilograms exceeds the daily maximum, so the case writes [1000 mg] once daily and explains that older, heavier children commonly hit this ceiling. Volume is converted for the [400 mg/5 mL] suspension and bracketed.
An allergy alternative, bracketed
For a reported penicillin allergy without anaphylaxis, the case names [cephalexin] with its weight-based regimen, and notes that a history of anaphylaxis would move the choice to [clindamycin] or [azithromycin], each with its own course length.
Back at school, and what to watch
Return is set after at least [12] hours of therapy with the fever gone, citing the Red Book. The father learns which symptoms in siblings merit testing and which later signs, such as joint pain or a muffled voice, mean coming back.
Where marks go in NU580 Unit 9
Two things get tested early: whether the diagnosis rests on testing rather than appearance, and whether the dose is right for this child. Treating on the rash alone, without a rapid test, contradicts the guideline the case expects, and so does ordering a culture after a positive rapid result. Dosing errors take the heaviest deductions: a weight-based figure written without the maximum, a twice-daily regimen totaled incorrectly, or a course shorter than [10] days for [amoxicillin]. A differential that lists conditions without saying why each is less likely reads as a list, not reasoning. School return stated as a day count rather than tied to therapy and fever tends to draw a comment. At the margin, complications named without a return trigger and references older than the editions in current use cost a few points.

NU580 Unit 9 questions, answered
Why bracket every dose in a sample?
Brackets mark values that belong to the composite case, not recommendations for any real child. Doses depend on weight, age, product concentration and current references, so every figure should be verified against the source your course uses. The sample shows each calculation in full precisely so the method can be checked and applied to your own case data.
Should the case study include a differential for a clear diagnosis?
Usually, yes. Even when the answer seems obvious, rubrics in advanced practice courses tend to reward a short differential with reasons each alternative is less likely. Two or three serious alternatives, briefly ruled down, show judgment without padding. The sample includes Kawasaki disease for that reason, then explains why two days of fever makes it unlikely.
How recent must the guideline be?
Cite the current edition your course accepts. For streptococcal pharyngitis the 2012 IDSA guideline has long been the standard reference, and the AAP Red Book appears in regular editions, so name the one you used. If a newer guideline exists for your condition, graders expect it, and citing a superseded one is a common accuracy deduction.
