A Blood Pressure of 104 That Reassured Everyone: Reading Acuity From Breathing, Lactate, Mottled Knees and a Low Temperature
NU650 · Unit 1 Discussion Board Post
Posted by [Student Name]
The patient is composite; vital signs and values are bracketed.
Initial Post
The patient I want to discuss was an [81]-year-old woman sent from assisted living because staff said she was "not herself." Her triage vital signs were blood pressure [104/62], heart rate [102], respiratory rate [24], temperature [35.9] degrees Celsius and a pulse oximetry reading of [94] percent without oxygen, with a nursing note that she "seems tired." Because her pressure was above 100 and she was talking, she was placed in a hallway bed with a moderate acuity level.
The same first page held four findings that nobody weighted. Her respiratory rate of [24] was the earliest one; fast breathing is often the body compensating for a metabolic acidosis before the pressure falls. Her lactate, drawn with the first labs, was [3.6] mmol/L, a marker of poor perfusion or impaired clearance. When I examined her, both knees were mottled and her capillary refill was about [4] seconds, which is skin evidence of the same problem. In septic shock, mottling that spreads from the knees has been linked to higher mortality, independent of blood pressure (Ait-Oufella et al., 2011). Finally, her temperature was below normal. A fever is frequently absent when frail older adults are infected, and in patients with severe sepsis a body temperature at or below 36.5 degrees was associated with more organ failure and higher 28-day mortality (Kushimoto et al., 2013).
Dividing her heart rate by her systolic pressure gives a shock index near [1.0]. Every one of those findings pointed the same way, and the one number that pointed the other way decided where she went.
This was also a screening problem. Our department uses qSOFA as its sepsis screen, and she scored [1] point, for her breathing rate, so the screen was negative. The 2021 Surviving Sepsis Campaign guideline advises that qSOFA should not be the only screen and favors SIRS, NEWS or MEWS in that role, because qSOFA is specific but misses many patients early (Evans et al., 2021). She met [three] SIRS criteria. She was diagnosed with urosepsis [three] hours later, after her pressure fell to [86/50].
My question for the group: in your emergency department or unit, which single finding would have made you move her to a monitored bed, and does your screening tool depend on qSOFA alone?
Reply to a Classmate Who Chose Lactate
You chose the lactate as the finding that would have moved her, and I agree it was the strongest single number on the page. I would add one caution for this patient: lactate can rise from impaired clearance in liver disease or from metformin, so in an older adult on several medications it should be read with the rest of the picture. Here, her mottling and breathing rate made the lactate harder to explain away. The guideline suggests measuring lactate in suspected sepsis and repeating it to guide resuscitation (Evans et al., 2021), which would have caught her trend even if the first value had been borderline.
Reply to a Classmate Who Defended the Triage Nurse
You made a fair point that the triage nurse followed the department's own screen, and that the error belonged to the system rather than one person. I agree with you. What I took from your post is that a better screen, such as NEWS, would have scored her respiratory rate, heart rate and low temperature together and placed her in a higher band. That is a policy change a nurse practitioner can raise at a quality meeting, which is more useful than asking one nurse to override a tool she was trained to trust.

What the NU650 Unit 1 assignment asks for
The first NU650 discussion asks how acuity is judged when a patient first arrives. You describe an acutely ill adult, identify the findings that show how sick the patient is, explain the physiology behind each, and connect the case to a screening tool or triage practice supported by current evidence. The prompt usually wants you to take a position on where the patient belongs, a monitored bed, a floor bed or intensive care, and to invite classmates to test it. Sections expect an initial post of about 500 words with two scholarly sources by midweek and two replies of 150 words or more by the end of the unit. Use a composite patient, since every classmate can read the thread.
How the NU 650 Unit 1 example is put together
The post puts the reassuring number first, because the claim under test is that one vital sign set the triage level. A paragraph then takes the four overlooked findings in turn and gives each a sentence of physiology: fast breathing as early compensation for acidosis, lactate as a sign of poor perfusion, mottling and slow refill as skin evidence of the same, and a low temperature as a recognized presentation in older adults. Studies on mottling in septic shock and on hypothermia in severe sepsis support the last two. The shock index is calculated in one line. A screening paragraph follows because the problem was also a system one. The replies each add one idea rather than agreeing.
Where the points sit in the NU650 Unit 1 rubric
Points in the Unit 1 rubric are spread across clinical content, use of evidence, critical thinking, peer responses and writing. Content earns full credit when each finding is linked to its physiology, not only listed. Evidence counts when the sources are current and fit the claim, such as the 2021 guideline for the qSOFA point and a mottling study for the skin finding. Critical thinking is where most points are won or lost: a post that sees a pattern across several findings scores higher than one that fixes on a single abnormal value. Peer responses are graded on substance, so a reply that adds a caution about lactate or a system-level fix earns more than agreement. APA format applies to in-text citations and references.
Common NU650 Unit 1 mistakes, and how to avoid them
Points are most often lost by repeating the triage error in the post itself, letting a normal-looking blood pressure frame the whole case. Another is listing abnormal findings without the physiology that connects them, which reads as a checklist rather than reasoning. Students often present qSOFA as a screening tool without mentioning that the current guideline advises against using it alone. Some posts use a real patient from clinical, which risks identifying someone. Replies are often too short or simply agree. Finally, check that each number has its unit and that the lactate, pressure and temperature appear with the time they were measured, since acuity is about timing as much as values.

NU650 Unit 1 questions, answered
Why use a composite patient instead of one from my own clinical?
A composite cannot identify anyone, and every classmate in the section can open a board thread. The sample assembles an invented older adult from typical findings, brackets every value, and follows any case the prompt supplies. Rotation patients, and whatever a preceptor checks or countersigns, are kept out of every sample.
Is it wrong to mention qSOFA at all?
No. It still predicts poor outcome in patients with suspected infection, which is what it was derived to do. The 2021 Surviving Sepsis Campaign guideline advises against using it alone to screen because its sensitivity is low. The sample mentions it in exactly that role, beside NEWS2, and lets the contrast in this patient make the point.
Where can I find a free NU650 Unit 1 sample paper?
This page holds the full NU650 Unit 1 discussion post with both replies, including the four overlooked findings and the screening point. If your prompt describes a different patient or asks about a different triage question, you can ask the desk for a free post written to your case.
Should an NU650 Unit 1 post use qSOFA or NEWS?
The sample uses the 2021 Surviving Sepsis Campaign position, which advises against qSOFA as the only screening tool and prefers SIRS, NEWS or MEWS for screening. qSOFA can still be mentioned for its original purpose, predicting poor outcome.
Can the NU650 Unit 1 post argue for intensive care?
It can if the findings support it. The sample stops short of that because the question it asks is about triage from the first page, but a pressure that falls despite fluids, rising lactate or new confusion would each justify intensive care in a reply.
