Before the Session
I came in thinking of pneumonia as one illness that is milder in the young and worse in the old. The plan in my head was the same for both: confirm it, give an antibiotic, adjust the dose for age. I had never thought about whether the first decision, to give an antibiotic at all, might be different at the two ends of life.
The two cases were posed together. [Ava], 3, had a fever of [39.1] C, a respiratory rate of [44] and crackles over the right lower chest; she was alert, drinking and saturating [95] percent on room air. Mr. [D.], 74, a retired barber, had three days of productive cough, and his daughter had noticed that morning that he was confused, calling her by her mother's name. His respiratory rate was [26], his blood pressure [104/62], his urea [8.2] mmol/L.
During the Session
The group separated the cases by three questions, taken here as we took them.
The first was what the organism is likely to be. For [Ava], the answer surprised me. In preschool children, viruses cause most community-acquired pneumonia, with respiratory syncytial virus, rhinovirus and human metapneumovirus among the common ones. The 2011 PIDS and IDSA pediatric guideline states that antibiotics are not routinely required for preschool children with community-acquired pneumonia, because viral pathogens are responsible for most of it, and recommends amoxicillin when a bacterial cause is suspected (Bradley et al., 2011). For Mr. [D.], a bacterial cause, most often Streptococcus pneumoniae, is likelier, and the 2019 adult guideline from the American Thoracic Society and IDSA recommends empiric antibiotics for community-acquired pneumonia (Metlay et al., 2019).
The first decision that separates them is not which antibiotic but whether one is needed, and the answer can be no at 3 and yes at 74.
The second question was how sick each patient is. For [Ava], the pediatric guideline's signs of severity, such as hypoxemia, marked work of breathing, dehydration or altered mental status, were absent, so she could be managed at home. For Mr. [D.], a classmate calculated his CURB-65 score aloud: confusion, 1; urea above 7 mmol/L, 1; respiratory rate 30 or more, 0; low blood pressure, systolic below 90 or diastolic 60 or below, 0; age 65 or older, 1. A score of 3. In the study that derived the score, mortality rose steeply with each point, and a score of 3 or more marked severe pneumonia (Lim et al., 2003). His confusion, which I had filed under "older adults get confused," was one of the points that decided where he should be treated.
The third question was where each should be treated. [Ava] could go home with a plan, fever control, fluids and a recheck. Mr. [D.] needed admission, and the discussion turned to whether he needed intensive care, which his score and blood pressure did not yet demand but which his team would watch for. One moment in the discussion stayed with me. A classmate who works in a pediatric urgent care said that parents often arrive expecting an antibiotic for a child with pneumonia and leave unhappy without one. She described how she explains the plan: the lungs are inflamed, most often by a virus at this age; antibiotics do nothing against viruses and bring their own diarrhea and rashes; and here is exactly what would make her change her mind, such as breathing getting harder, the child not drinking or a fever lasting more than a few more days. That explanation made the watchful plan sound like care rather than refusal, and I realized the pediatric decision depends as much on that conversation as on the examination.
After the Session
I now think of the two pneumonias as different problems that share a name. For the preschooler, the key decision is whether an antibiotic is needed, and a careful examination and the expected viral cause may allow a watchful plan with clear return instructions. For the older adult, the key decision is severity and setting, and signs that seem nonspecific in older people, such as confusion, carry real weight in the scores that guide it.
The session also changed how I think about confusion. I had treated it as background in older adults, something that happens with any illness. The CURB-65 score counts it as a sign of severity for a reason: it reflects the brain's response to infection, low oxygen or low blood pressure, and it predicts death. I will not dismiss it again.
What I will do differently: for a young child with suspected pneumonia, I will ask whether a virus is likelier and document why I did or did not prescribe. For an older adult, I will calculate a severity score before deciding where treatment happens, and I will write it in the note. I will also remember that the same word can hide two different sets of decisions.

How this NU568 Unit 5 example is structured
Chronology holds the reflection together, but each section does a distinct job. The first states the author's prior belief precisely enough to be tested, including where it came from, adult rotations applied downward. The second is the longest and the most specific. It attributes the turning points to classmates by role, records the facilitator's question about which organism was most likely at each age, and sets out the two management logics side by side: pediatric decisions weighted toward viral cause, hydration and oxygen saturation, adult decisions weighted toward a severity score and comorbidity. The third section states what the author now believes and one limit on it, since a preschooler with focal findings and high fever may still have a bacterial pneumonia. The last lines commit to a habit for later cases in the course.

For a live Unit 5 seminar in NU568, bring the two cases and your own notes from the discussion; for the written route, the posted prompt does the same job. Include the rubric in both cases. Following your turning point and naming each guideline by year, the reflection sample arrives within 24-48h at no charge the first time. The paper above is an original model document written by our desk, not a submitted student paper and not an official Purdue University Global document.
NU568 Unit 5 questions, answered
Should the reflection include dosing for either patient?
Usually not. The seminar compares reasoning across ages, and doses add length without showing that reasoning. If the prompt asks for management, name the drug class and the guideline behind it, with any specific agent in brackets. A reflection is judged on what changed in your thinking, and a regimen rarely demonstrates that on its own.
What if the seminar compared a condition other than pneumonia?
The structure holds for any condition: your prior belief, the specific differences the session exposed in cause, assessment and plan, and a limit on your revised view. Urinary infection, hypertension and asthma are frequent choices for age comparisons. Tell the desk which condition your session used, and the sample will follow that comparison instead.
Can I reflect on a session I watched as a recording?
Often yes, if your section offers recordings alongside a written alternative. Name the session and say how you engaged with it, then reflect on the reasoning as you followed it. Avoid claiming to have spoken in a discussion you watched. An honest account of what you noticed from the recording is usually graded on the same criteria as live participation.
