Application: asthma management stepwise approach essay
A five-bullet asthma paper whose hardest requirement is hidden in a subordinate clause — the arterial blood-gas pattern during an exacerbation, which most students describe backwards.

Which asthma bullet is worth the most, and why is it hidden?
Five bullets, and the marks are not spread evenly across them. The clause most often dropped is the smallest one: *then, explain the changes in the arterial blood-gas patterns during an exacerbation*. It is attached to the pathophysiology bullet by a semicolon rather than given its own line, so it reads like an afterthought and gets treated as one. It is not. It is the only part of this paper that asks you to reason from mechanism to a number a clinician would actually see, and it is the part a marker can grade unambiguously. Give it a paragraph of its own, and write that paragraph before you write the drug sections, because it disciplines everything else you say about severity. Everything downstream — which drugs count as rescue, when a step-up is justified, what an action plan tells a patient to watch for — is easier to argue once you have committed to a mechanism on paper.
The blood-gas answer is also the one most students get backwards. The intuitive guess — acidosis, because the patient cannot breathe — describes the end of the story, not its beginning. A mild or moderate exacerbation produces **respiratory alkalosis**: tachypnoea blows off carbon dioxide, so PaCO₂ falls while hypoxaemia develops from ventilation-perfusion mismatch caused by heterogeneous air trapping. The dangerous moment is the one that looks like improvement. As the work of breathing exhausts the patient, PaCO₂ *normalises* and then rises, so a report reading “normal PaCO₂” in a visibly distressed asthmatic is a warning of impending respiratory failure rather than reassurance. Say that explicitly; it is the sentence that separates a competent answer from a memorised one. The reason the pattern reverses is mechanical rather than metabolic: obstruction and fatigue eventually cut alveolar ventilation below what carbon dioxide clearance requires, so the gas result follows the patient's effort rather than the severity of the obstruction.
Keep chronic asthma and acute exacerbation genuinely separate, because the brief asks how they are similar **and different** and most papers describe one mechanism twice. Chronic asthma is a structural story: persistent eosinophilic and mast-cell inflammation, basement membrane thickening, smooth muscle hypertrophy, goblet cell and mucus gland hyperplasia — airway remodelling that develops over years and does not fully reverse. An exacerbation is an acute-on-chronic event: bronchospasm, mucosal oedema and mucus plugging superimposed on that remodelled airway, producing air trapping and hyperinflation. The shared substrate is inflammation; the difference is timescale and reversibility, and that difference is exactly what makes controller therapy and rescue therapy different classes. Say which changes reverse with a bronchodilator and which do not, because that single distinction explains why a rescue inhaler cannot substitute for a controller. Remodelling is why a patient can be symptom-free and still have measurably abnormal lung function.
The drug halves reward categorical precision. **Long-term control** — inhaled corticosteroids, long-acting beta-agonists as add-on, leukotriene receptor antagonists, biologics — treats inflammation and is taken whether or not the patient feels unwell. **Quick relief** — short-acting beta-agonists, ipratropium, systemic corticosteroids in exacerbation — treats bronchoconstriction. The classic error is filing a LABA under quick relief because “long-acting” sounds stronger, or offering an inhaled corticosteroid as a rescue drug. Be careful with currency too: current international guidance no longer recommends short-acting beta-agonist-only treatment and uses ICS-formoterol as the reliever in some tracks, which is not what older course texts describe. Name a representative agent for each category rather than the category alone, since a marker cannot tell whether you know the classification or have copied a heading. Where your text and current guidance disagree, cite both and say which you are following.
*Impact on adults and children* wants adverse effects and practical consequences, not a second efficacy paragraph. For children the specific, citable concern is inhaled corticosteroid effect on growth velocity, alongside delivery — spacers and masks rather than technique-dependent inhalers. For adults, oral candidiasis and dysphonia from inhaled steroids, the systemic burden of repeated corticosteroid bursts, and the narrow therapeutic window of theophylline where it is still used. Then note whose problem each is: an adverse effect that lands on a caregiver rather than the patient changes what adherence support has to look like, which is the bridge into the assignment's last bullet. Growth velocity is the example worth getting precise, because it is frequently overstated into a claim about final adult height that the evidence does not support. Delivery technique deserves a sentence of its own, since a correctly prescribed inhaler used incorrectly is pharmacologically identical to no inhaler at all.
The last two bullets are where papers become interchangeable, and both have a hidden second audience. The stepwise approach assists *health care providers and patients* — providers get a defensible escalation rule, but patients get something too, and it is worth saying: a step-down goal, so therapy is not simply ratcheted upward forever, and a written action plan tying steps to symptoms they can recognise. Likewise the adherence plan must actually differ by age. Young children depend on a caregiver and a school medication policy; adolescents have the worst adherence of any group and it is usually about autonomy and visibility rather than forgetting; older adults face dexterity, inhaler technique and polypharmacy. Three different problems, three different plans. Ask what actually stops each group taking a daily medicine, because the answer differs by age far more than the medicines do.
Bullet in the brief | What earns the marks | The version that loses them |
|---|---|---|
Pathophysiology of both | Remodelling versus acute-on-chronic event | One mechanism described twice |
Blood-gas changes | Alkalosis first, rising PaCO₂ as a red flag | “Respiratory acidosis and hypoxaemia” |
Control vs relief drugs | Correct class for each, with the mechanism | A LABA filed under quick relief |
Impact on adults, children | Adverse effects and who carries them | Efficacy restated for two age groups |
Stepwise approach | What it gives providers AND patients | An escalation ladder, providers only |
Adherence plan | Three genuinely different age plans | One plan with the ages named |

Here are some helpful links Student paper example Citing Sources The Writing Center is a great resource Welcome to class Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to. I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you. Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted. If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations. Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements. Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week. I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!

From pathophysiology to a stepwise plan and adherence by age
Pathophysiology of chronic asthma
Set out persistent inflammation and airway remodelling as a structural, long-timescale process.
Pathophysiology of acute exacerbation
Describe bronchospasm, oedema and mucus plugging superimposed on the remodelled airway.
Arterial blood-gas changes
Trace the pattern from early alkalosis and hypoxaemia to rising PaCO₂ with fatigue.
Long-term control and quick-relief drugs
Present both classes by therapeutic role, with representative agents and mechanisms.
Impact on adults and children
Give adverse effects and practical burdens for each group.
The stepwise approach
Explain assessment, step-up and step-down, and what each audience gains from it.
Medication adherence by age
Build three plans for three developmental stages and say what drives non-adherence in each.
Finding blood-gas evidence and current stepwise guidance
Recommended databases
- The assigned Huether and McCance and Arcangelo chapters
- PubMed Central
- NHLBI asthma guidelines
- Global Initiative for Asthma reports
Search sequence
- 1.Read the assigned chapters first, since the paper is built on them and the stepwise figure your marker has in mind is the one in the Arcangelo text.
- 2.Then check current guidance against those chapters, because asthma pharmacotherapy has changed materially since the editions the brief names and a paper that notices this is stronger than one that does not.
- 3.Search specifically for arterial blood-gas findings in acute asthma rather than for asthma pathophysiology in general, as the progression from alkalosis to hypercapnia is what the brief's clause is asking about.
- 4.Search inhaled corticosteroid adverse effects by age group, so the children and adults sections rest on evidence rather than on the same paragraph twice.
Asthma pathophysiology and management guideline sources
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.
Nothing here is cleared for citation until you have read it.
- 01
Status Asthmaticus
StatPearls, NCBI Bookshelf · 2025
The source for the clause most papers get wrong. It states that mild and moderate exacerbations typically produce respiratory alkalosis from tachypnoea, that hypoxaemia develops as severity increases, and that PaCO₂ may falsely normalise as fatigue reduces respiratory effort — with hypercarbia and hypoxaemia indicating impending respiratory failure. It also carries a table of arterial blood-gas findings in acute asthma, and explains the air trapping and ventilation-perfusion mismatch that produce them.
- 02
Asthma
StatPearls, NCBI Bookshelf · 2025
Covers the chronic side of the comparison — the inflammatory cell populations, airway remodelling and hyperresponsiveness that distinguish established asthma from the acute event — together with the drug classes and their mechanisms. Use it to keep the two pathophysiology sections genuinely different rather than restating one of them.
- 03
2020 Focused Updates to the Asthma Management Guidelines
National Heart, Lung, and Blood Institute, NIH · 2020
The US framework the course's stepwise approach descends from, updated well after the assigned chapters were written. Citing it lets you present the stepwise approach as current practice rather than as a textbook diagram, and it is the natural place to source the step-down half of the argument that most papers omit.
- 04
2025 GINA Strategy Report
Global Initiative for Asthma · 2025
The currency check. Present-day international guidance no longer recommends short-acting beta-agonist-only treatment and positions ICS-formoterol as a reliever, which is a different picture from the one the assigned chapters describe. Noting the divergence — rather than silently choosing one — is the cheapest way to show the reading went beyond the required texts.
Before the asthma management essay is submitted
Common mistakes
- Skipping the arterial blood-gas clause because it is attached to another bullet rather than given its own.
- Reporting respiratory acidosis as the early exacerbation pattern when it is the late one.
- Treating a normalising PaCO₂ as improvement rather than as a warning sign.
- Describing chronic asthma and exacerbation with the same mechanism twice.
- Classifying a long-acting beta-agonist as a quick-relief drug.
- Answering “impact on adults and children” with efficacy instead of adverse effects.
- Explaining the stepwise approach only from the provider's side.
- Writing one adherence plan and labelling it with three age groups.
- Using only the assigned chapters, so the drug guidance is a generation out of date.
Submission checklist
- Chronic and acute mechanisms are described separately and then compared.
- The blood-gas paragraph states the early pattern and the late pattern.
- The significance of a normal PaCO₂ in a distressed patient is stated.
- Long-term control and quick-relief drugs are in the correct categories.
- Adverse effects are given for adults and separately for children.
- The stepwise section says what patients gain, not only what clinicians gain.
- Step-down, not only step-up, appears in the stepwise section.
- The adherence plans for three age groups differ in substance.
- Title page, introduction, summary and references are present.
