Illness Scripts: Acute Bronchitis, Lung Cancer and Bronchiectasis as Causes of Coughing Up Blood, Laid Out in Parallel Slots
Why These Three
For the course's patient, whose streaked sputum began with a cold three weeks ago, the common and dangerous causes of hemoptysis in adults include acute respiratory infections such as bronchitis, bronchiectasis, chronic obstructive pulmonary disease and malignancy (Earwood & Thompson, 2015). Three scripts are written here: acute bronchitis, the most likely; lung cancer, the one that must not be missed; and bronchiectasis, a less common cause that can mimic both. Each script fills the same slots in the same order so they can be read across. Illness scripts organize what a clinician knows about a disease around who gets it, how it develops and how it shows itself, which makes comparison with a patient possible (Bowen, 2006).
The Scripts
Table 1
Three Illness Scripts for Hemoptysis in Parallel Slots
| Slot | Acute bronchitis | Lung cancer | Bronchiectasis |
|---|---|---|---|
| Who tends to get it | Any adult, often after a viral upper respiratory infection | Older adults with heavy smoking history; risk rises with age and pack-years | Adults with past severe infections, cystic fibrosis or immune problems |
| What sets it off | A viral infection inflaming the airway lining | Long exposure to tobacco smoke and other carcinogens | Damaged, widened airways that trap mucus and become repeatedly infected |
| How fast it builds | Days; cough may linger up to three weeks | Weeks to months, often insidious | Years, with flares |
| What it does | Cough, sometimes with streaks of blood from inflamed mucosa | Persistent or changing cough, hemoptysis, sometimes weight loss or chest pain | Chronic daily productive cough, recurrent infections, intermittent hemoptysis |
| What travels with it | Recent cold; no weight loss; usually clears | Weight loss, hoarseness, clubbing, recurrent pneumonia in one area | Large volumes of sputum most days for years |
Note. Note. Scripts summarize general clinical knowledge; causes listed in Earwood and Thompson (2015).
Semantic Qualifiers
Pairs of opposing terms sharpen the scripts. Acute against chronic separates bronchitis, days to weeks, from bronchiectasis, years. Streaked against frank separates the small amounts typical of bronchitis from larger bleeds. Productive against dry, and first episode against recurrent, add further contrasts. For this patient, the qualifiers are subacute, three weeks; streaked; first episode; productive cough after a cold. They fit bronchitis well, but subacute and first episode in a former heavy smoker also fit early lung cancer.
The Separator
The feature that best separates the two leading scripts is time and trajectory. Bronchitis improves: the cough and streaking fade within about three weeks. Lung cancer does not: the symptom persists, recurs or changes. This patient is at the boundary, three weeks in. That makes the separator a reason to look rather than a reason to reassure.
What Stays Out
Each script leaves out treatment and detailed pathology, which do not help match a patient to a disease. Rare causes, such as vasculitis or foreign bodies, are left out of this set; they would be added only if the history pointed to them, such as kidney problems or an inhaled object.
Carrying One Forward
The lung cancer script carries forward to the rest of this course, because whether it can be set aside decides when the workup ends. For this patient, an age of 58 and about 36 pack-years make the script's first slot a close fit. In a large primary care cohort, the three-year positive predictive value of a first episode of hemoptysis for respiratory tract cancer was 7.5% in men (Jones et al., 2007). That figure will serve as the patient's starting probability in the test characteristics problem set.
How the Scripts Would Change for Another Patient
The same three scripts would weigh differently in another patient. For a 25-year-old nonsmoker with streaked sputum after a cold, the bronchitis script would fit almost entirely and the cancer script would barely open, because its first slot, an older heavy smoker, would not match. For a 70-year-old with a lifelong daily cough and large volumes of sputum, the bronchiectasis script would move forward. Scripts do not change from patient to patient; what changes is how well each patient fits each slot. That is why the scripts are written in general terms and the matching is done separately, as in the next assignment's problem representation.

PA 503 Week 2 instructions, in plain terms
Week two asks you to write two or three illness scripts for conditions that could explain a complaint. Lay them out identically, with the same slots in the same order, so a reader can scan across them: who tends to get the condition, what sets it off, how fast it develops, what it does and what usually travels with it. Keep each script short and leave out treatment and detailed pathology. Add semantic qualifiers that sharpen the contrast, such as acute against chronic. Identify the single feature that best separates the leading scripts. Say what you deliberately left out, and carry one script forward into the next stage of reasoning about the patient.
Inside the PA 503 Week 2 example
The scripts compare acute bronchitis after a viral infection, lung cancer in older heavy smokers and bronchiectasis with years of daily sputum. A table fills five slots for each, from who gets it to what travels with it. Semantic qualifiers place the patient as subacute, streaked, first episode and productive after a cold, fitting bronchitis but not excluding early cancer. Time and trajectory are named as the separator, since bronchitis fades within about three weeks and cancer persists. Rare causes are left out unless history points to them. A section shows how the same scripts would fit a young nonsmoker or an older lifelong cougher, and the cancer script carries forward a 7.5% starting probability.
Reading the PA 503 Week 2 grading rubric
Most points go missing when the scripts are drafted independently, so the slots drift, one carries an epidemiology line and another does not, and the comparison the exercise exists for becomes impossible. Nearly as costly is a script padded with textbook detail, such as treatment or histology, that does not help match a patient to a disease. Scripts without semantic qualifiers, with no separating feature named or with nothing carried forward also lose points. Strong work fills the same slots in the same order, keeps each script short, adds qualifiers, names the separator, states what was left out and carries one script into the patient's case. A note on how fit would change for a different patient is a strong addition.
PA 503 Week 2 help: mistakes that cost points
Illness scripts take practice to keep short and parallel, because textbooks present diseases in long and varied formats. If you share the complaint and the conditions your section assigned, we can help you set up identical slots, choose semantic qualifiers that sharpen the comparison and name the feature that best separates the leading scripts. We can also help you trim textbook detail that does not help with matching. The scripts and their wording stay yours. Instructors who prescribe a slot order get exactly that order in the custom sample, slot for slot.
Get a PA-503 Week 2 example written to your instructions
Send the conditions your section named, the word cap, and the format it wants the comparison in, and a custom example is written to those and returned within 24 to 48 hours, the first one free. Where the assignment leaves the conditions open, the desk picks a set that genuinely competes rather than three nobody would ever confuse.

PA 503 Week 2 questions, answered
How many conditions belong in the set?
Two or three is the usual instruction, and the exercise stops working above four because the comparison turns into a survey. What matters more is that the conditions genuinely compete: three nobody would confuse produce a set with nothing to separate. If your instructions name them, the example uses those; if not, the desk picks a set that actually collides.
Does a script need citations?
Most sections want a course text or a clinical reference behind the epidemiology and the typical findings, since those are claims rather than opinions. The comparison itself is your own reasoning and is not cited. Follow the reference style your section publishes, and send it along so the example arrives already in that format.
Can a table replace the written scripts?
Some sections ask for exactly that and others forbid it outright. A table makes the parallel slots obvious and gives the separator an easy home, so where the choice is open it is usually the stronger format. Send the instructions and the example is built in whichever form your classroom expects to receive.
