Factors are the easy half; adjustments are assessed
The prompt gives you three example categories and then asks a second question that most posts under-answer. Identifying factors is straightforward; discussing how you will adjust the history and physical around them is the assessed skill. Adjust is a doing word, and the marker is looking for changed practice rather than awareness. That means naming what you would ask that you would not otherwise ask, what you would examine differently, in what order, in what position, and what you would interpret differently when you found it. A post that lists five factors and then concludes that the advanced practice nurse must consider each carefully has answered the first half twice. Structure the post so every factor is immediately followed by its adjustment, and the second half cannot be left out. Pairing them also stops the post becoming a textbook summary of the respiratory examination. Every factor should earn an adjustment sentence of its own.
Take the three named categories in turn, because each changes the examination in a different way. A disease process changes what is normal for this patient: emphysema alters the baseline percussion note and the position of the diaphragm, so hyperresonance is expected rather than alarming, while the same finding in a healthy adult is a pneumothorax until proven otherwise. Chronic disease also changes the yield of individual manoeuvres, since tactile fremitus and egophony are less informative in a hyperinflated chest. The adjustment is therefore interpretive as well as procedural: you are recalibrating what a finding means, and saying so explicitly is worth more than adding another manoeuvre. Say which manoeuvres you would still perform in a hyperinflated chest and which you would weight less heavily, because that judgement is the clinical content the discussion is looking for. A post that adds tests without dropping any has not really adjusted anything.
Musculoskeletal changes alter access and mechanics rather than interpretation. Kyphosis, scoliosis, pectus deformity, obesity, prior thoracic surgery and rib fractures each restrict where you can place a stethoscope, how far the chest can expand, and whether posterior fields can be reached at all. The adjustments are concrete and easy to write specifically: examining seated rather than supine, examining in stages if the patient cannot sustain a position, documenting which fields could not be auscultated rather than leaving the record implying a complete examination, and increasing reliance on the history and on measured respiratory rate when the physical examination is constrained. Age belongs here too, since reduced chest wall compliance and weaker cough change both the examination and what the patient can do on request. Say plainly that an unreachable field is a gap in the data rather than a normal finding, since the record will be read later by someone who was not there.
Environmental risks change the history far more than the examination, and this is where the post can differentiate itself. Occupational exposures, second-hand smoke, vaping, wood smoke and indoor air quality, mould and damp housing, altitude, and local air pollution all belong in a respiratory history and are routinely omitted from it. The adjustment is a set of specific questions: what the patient does and has done for work, what materials they handle, whether symptoms change on days off or on holiday, what heats the home, and whether anyone else in the household has the same symptoms. That last question does a lot of work in a short consultation. Say why you would ask each one rather than listing them, since the reasoning is what the discussion is assessing. Symptoms that improve away from home or away from work are the single most useful discriminator in an occupational respiratory history, and the question takes seconds to ask.
Two additions strengthen a post noticeably. The first is naming a factor outside the three categories offered, which shows you read the word such as as an opening rather than a closed list: immunosuppression, pregnancy in the third trimester, a language barrier requiring an interpreter, or a patient who cannot follow the breathe deeply through your mouth instruction because of cognitive impairment. The second is saying what you would do when the physical examination cannot be completed. Advanced practice reasoning includes knowing when the examination has run out and imaging, spirometry or pulse oximetry has to carry the diagnostic weight, and naming that threshold is a stronger answer than implying that a thorough examination always suffices. Naming that threshold tells your peers how you practise rather than what you have read. The honest version of this section names a case where you would order a chest film before completing the examination rather than after it.
On execution, the requirements ask for evidence of review of the course material, websites and literature through proper APA citation, which means three kinds of source and a genuinely cited post rather than a reflective one. Cite where you make a claim about a finding's sensitivity or about an exposure's respiratory effect, not after every sentence. Keep the post organised as factor and adjustment pairs so a marker can see both halves answered, and consider ending with the single adjustment you think is most often skipped in practice, since a stated view gives your peers something specific to respond to and this is a discussion rather than a summary. Pick the adjustment you think is most often skipped and say why you think it is skipped. Keep the citations attached to claims rather than sprinkled, and let the closing view do the work of inviting a reply.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Pair every factor with a specific change to the history or examination.
- 02Recalibrate what a physical finding means in the presence of chronic disease.
- 03Adapt examination technique to musculoskeletal and positional constraints.
- 04Build an occupational and environmental exposure history deliberately.
- 05Recognise when examination has reached its limit and testing must carry the weight.

Course-wide instructions that accompany this question
ADDITIONAL INSTRUCTIONS FOR THE CLASS Discussion Questions (DQ) Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses. Weekly Participation Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week. APA Format and Writing Quality Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. NU609-7C Unit 5 DQ 1 I highly recommend using the APA Publication Manual, 6th edition. Use of Direct Quotes I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source. LopesWrite Policy For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score. Late Policy The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading. Communication Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
