Concept Map: Perfusion Drawn as Sixteen Propositions, Where the Words on the Arrows Carry the Teaching and the Boxes Are Nearly Free
Purpose
This concept map is a teaching model for the perfusion unit of our third-semester concepts course. It will be shown to students after they have drawn their own maps, as an example of what a map should do. Most student maps I receive place perfusion in the center and attach eight or ten terms around it: heart failure, blood pressure, capillary refill, edema, shock. The terms are correct, but the lines between them are unlabeled or labeled with words such as "related to." The result is a vocabulary list arranged in a circle. It shows that the student has heard the words, not that the student understands how they connect.
A review of concept maps in medical education found that their value for learning lies in representing relationships between concepts, which requires learners to state how one idea affects another, and that maps can support meaningful learning and assessment when used this way (Daley & Torre, 2010). The linking phrase on each arrow is therefore where the thinking happens, and where a teacher can see it.
How the Map Is Built
The map below is written as sixteen propositions. Each proposition is one arrow: a starting concept, a linking phrase and an ending concept, which together form a statement that can be judged true or false. Drawn, the map places perfusion at the top, the causes of impaired perfusion below it on the left, the tissue consequences on the right and the nursing assessments at the bottom, with the boundary concepts to the side. Written as propositions, it can be checked line by line.
Table 1
The Perfusion Map as Sixteen Propositions
| No. | From | Linking phrase | To |
|---|---|---|---|
| 1 | Perfusion | is the flow of blood through | tissues and organs |
| 2 | Adequate perfusion | depends on | cardiac output, open vessels and pressure around vessels that does not close them |
| 3 | Reduced cardiac output | lowers flow to | all tissues, first those the body can least afford to spare, such as the kidneys and skin |
| 4 | Narrowed or blocked arteries | lower flow to | the tissue beyond the narrowing only |
| 5 | Rising pressure in a closed compartment | squeezes shut | the vessels inside that compartment |
| 6 | Reduced flow | is shown in skin by | coolness, pallor or mottling and capillary refill longer than three seconds |
| 7 | Reduced flow to the kidneys | is shown by | falling urine output and a creatinine that climbs over days |
| 8 | Reduced flow to the brain | is shown by | new confusion or restlessness |
| 9 | Reduced flow to a limb | is shown by | pain, weak or absent pulses and delayed healing |
| 10 | Blood pressure | indicates adequate perfusion only when | tissue signs also show enough flow |
| 11 | The body | compensates for falling flow by | raising heart rate and narrowing skin vessels |
| 12 | Compensation | can hide falling perfusion until | it fails, which is why trends matter more than single values |
| 13 | Low oxygen saturation with warm, well-filled tissue | points to | gas exchange, not perfusion |
| 14 | Pallor and breathlessness with normal flow and saturation | points to | low oxygen-carrying capacity, not perfusion |
| 15 | Nursing assessment of perfusion | compares | both sides, over time, and against the patient's own baseline |
| 16 | Treatment of impaired perfusion | targets | the cause of reduced flow, not the number on the monitor |
What the Linking Phrases Do
Several propositions are built to correct errors students make. Proposition 10 uses the phrase "indicates adequate perfusion only when" rather than "is related to," because students treat blood pressure as a measure of perfusion. The phrase states the condition under which it is one. Proposition 4 says that blocked arteries lower flow "to the tissue beyond the narrowing only," because students often expect peripheral arterial disease to show in vital signs. Proposition 12 connects compensation to a teaching point about trends, so that a normal heart rate or blood pressure is not read as reassurance in a patient who is compensating.
Propositions 13 and 14 sit at the edge of the map and point outward. They exist because the boundary between perfusion and its neighbors is where students misclassify patients, as the unit's concept brief showed. A map with no boundary propositions would imply that everything with low oxygen belongs inside perfusion.
What the Boxes Do Not Do
The map has fewer boxes than most student maps. It does not include every condition, because conditions are exemplars, not parts of the concept. It does not include drugs, because treatments belong to the cause, which proposition 16 states. Giddens (2021) organizes concepts by their scope, attributes and exemplars; a concept map is most useful when it shows the attributes and how they connect, and leaves the exemplars to be recognized through them. A student who can explain propositions 2 through 9 can recognize a perfusion problem in a condition the map never names.
Using the Map in Class
Students will first draw their own perfusion maps in pairs, with a rule that every line must carry a phrase that makes a true statement. They will then exchange maps with another pair and mark each proposition true, false or too vague to judge. Only then will this model be shown, projected large enough that every linking phrase can be read from the back of the room. Students will compare it with their own maps and add or correct at least three propositions. The comparison, not the model itself, is the teaching. Students will also be asked which of their own propositions they would now reject and why. In past cohorts, the most common rejected proposition has been some version of "low blood pressure causes poor perfusion," which is true in some patients and misleading in others. Writing a better linking phrase for it, one that states the condition, is often the moment a student grasps what the concept is.
The same structure will be used for assessment later in the unit. Students will be given a partial map with blank linking phrases and asked to complete them, which tests understanding of relationships more directly than asking them to list signs and symptoms. Concept-based learning aims for this kind of deep understanding that students can carry into clinical practice (Nielsen, 2016), and the linking phrases are the best evidence of it on paper.

The Chamberlain NR 536 Week 4 instructions
For Week 4 you typically create a concept map for a nursing concept and explain how you would use it in teaching. Prompts ask for the map, the relationships it shows, how it reflects the concept's attributes and exemplars, and its use with learners. Focus on the linking phrases. A map is only as good as what its arrows claim; a label such as related to shows nothing. Write each link so that, read with its two concepts, it forms a statement that is true or false. Include links that correct common misconceptions and links that mark the concept's boundary. Keep conditions and drugs out unless they are part of the concept itself. Explain classroom use and cite concept map literature in APA 7.
How the NR 536 Week 4 example is put together
The paper opens by describing the typical student map, a vocabulary circle with unlabeled lines, and cites a review showing that concept maps work when they state relationships. It explains how the map was built and presents sixteen numbered propositions in a table, from what perfusion is through causes, tissue signs, compensation and boundaries to assessment and treatment. A section explains how specific linking phrases correct errors, including a conditional phrase about blood pressure. Another explains what the map leaves out and why. The final section describes students drawing maps in pairs, marking each other's propositions true, false or vague, comparing with the model and completing a map with blank links later.
Where the points sit in the NR 536 Week 4 rubric
Concept map rubrics usually reward accurate representation of the concept, meaningful relationships among ideas, clear linking phrases, appropriate scope and a sound plan for teaching use. Graders read the arrows closely, so propositions that make precise, checkable claims earn more than extensive node lists. Links that address known misconceptions show pedagogical insight. Boundary links that connect the concept to its neighbors demonstrate understanding of its edges. Explaining exclusions shows judgment about scope. A teaching plan that has students construct and critique maps before seeing a model reflects evidence on active learning. Clear presentation of the map, whether drawn or tabulated, supports the grade.
NR 536 Week 4 help from the desk
The most common weakness is a map crowded with correct terms linked by vague phrases. Make each link a statement. Another is a map that lists conditions around the concept, which turns it into a catalog of exemplars rather than a picture of how the concept works. Students also leave out the boundary, so the map seems to cover every patient with similar signs. Add links outward. Avoid arrows that point both ways without explanation. Check each proposition by reading it aloud; if it is not clearly true or false, rewrite it. Finally, plan how learners will use the map, since a model shown before they try their own teaches less than one they compare with afterward.

NR 536 Week 4 questions, answered
Does the map need a particular program, or is a hand drawing acceptable?
Sections almost never require a specific tool and no points ride on the choice. Legibility does carry weight: labels that survive being printed, arrows whose direction is unambiguous, and a layout that does not force a reader to trace a line across the page. A clean hand drawing photographed straight is usually fine unless your classroom asks for a file type.
How does the narrative avoid repeating the diagram?
By arguing instead of describing. The drawing already shows that one thing affects another, so the words are spent on why that arrow points the way it does, which patient makes it visible, and where a reasonable colleague would place it differently. A narrative that reads as a caption is the most common reason strong diagrams come back with middling marks.
Should every exemplar from earlier weeks appear on the map?
No, and crowding them in usually costs more than it adds. Two or three cases attached to different attributes demonstrate the spread the concept needs. A map is a claim about relationships, not a record of coverage, and a reader forced to hunt for the structure through a field of patient labels will not find the argument being made.
Where can I find a free NR 536 Week 4 sample paper?
The sixteen-proposition perfusion map shown above is the whole NR 536 Week 4 sample, openly available on this page. If you are mapping another concept, send it to us and a map with checkable linking phrases can be built.
Why does the NR 536 map focus on linking phrases?
Because the phrase on each arrow shows whether the learner understands how two ideas connect. The sample writes every link as a statement that can be judged true or false, which is what a reader grades.
