What a finished PA-520 Week 3 obstructive versus restrictive memo looks like
One page, in memo form, carrying whichever header block the section's template prints and a subject line written so the record can be identified without opening the file. The finding comes first, in a sentence that could be read on its own and still mean something. Underneath it the figures appear with units, arranged so the reader can follow the same route the writer took. The shape of the flow-volume loop is described in words rather than gestured at, since most classroom versions supply a picture and mark the description of it. A short limits paragraph states what spirometry is unable to demonstrate on its own, and a single line names the measurement that would. The sign-off runs to one sentence.
How a PA-520 Week 3 example is structured
Header block, then the finding, then the evidence, in that order, because a memo holding its conclusion back until the last paragraph reads as an essay and gets marked as one. The evidence runs from the ratio to the capacity, each figure carrying its units, and the loop description sits beside whichever figure it supports. Reasoning is written as elimination: what a preserved ratio with a reduced capacity is consistent with, and what it rules out. The limits paragraph follows immediately, so the memo never leaves an overstatement standing at the foot of a page. Figures the memo does not rely on are left out rather than displayed, since a memo is chosen for compression. The next-measurement line comes last and is specific about which test and what it would show, not a general suggestion that more work is needed.
Finding first
The memo states its conclusion in the opening sentence, and everything below works to support that one sentence. Holding the finding back is the commonest way this record loses its form points.
The loop, described
Where a trace is supplied, its shape is put into words: where the curve falls away, how the descent behaves, what that appearance is consistent with. An adjective on its own earns nothing.
What spirometry cannot demonstrate
A reduced capacity with a preserved ratio is suggestive and not confirmatory, and the memo says so plainly rather than leaning on the figures for more than they carry.
Family, not name
The assignment asks which broad family the figures belong to. A named illness in place of a family answers a different question and forfeits the row the memo was set for.
The next measurement, named
The closing line names one specific test and states what result would settle the question, which turns a pattern into something the reader can act on.
Where marks go in PA-520 Week 3
The deduction that hurts most here is restriction declared confirmed on spirometry alone, since the memo has then asserted something the supplied figures are unable to demonstrate. A loop summarized in an adjective rather than described costs the second row on most rubrics. Memos written as essays, with the finding withheld until the close, lose the form points even where the reasoning underneath is sound. Length is its own risk here, since a memo running past a page has stopped being one. A mixed picture forced into one family costs more than an honest statement that the figures sit between them. And a memo closing without the next measurement named leaves its reader holding a pattern with nothing to do about it, which is the one outcome the memo form exists to prevent.

PA-520 Week 3 questions, answered
Can restriction be confirmed from spirometry alone?
No, and saying so is worth points. A reduced capacity with a preserved ratio is consistent with restriction and also with an effort that ended early or with air trapped behind obstruction. The finished memo records the pattern as suggestive, names lung volume measurement as the thing that would confirm it, and leaves the claim where the evidence leaves it.
How formal does the header block need to be?
Formal enough to be filed and found again: addressee, author, the date, and a subject line carrying the record and the question, in whatever format your section's template gives. Where no template is posted, a four-line block is standard and takes seconds to write; markers tend to check that it exists rather than grade its typography.
The figures look like both families. What then?
Write that. A combined picture is a legitimate finding, and the memo states which features point each way, notes that spirometry cannot separate them, and names the measurement that would. Forcing an ambiguous set into one family to produce a tidy finding is the commonest way this record loses its reasoning row.
