Why Feeding Fails, and What Helps Right Now
Anatomical domain · Lesson 6 of 20 · Human Body Systems (HBS)
Today's goal: Explain why an open cleft prevents an infant from generating suction, and recommend feeding interventions that compensate, using Mateo's anatomy.
What a finished product looks like
This is a model of the work you should turn in. Use it to check your own: match the structure and the level of detail, do not copy it. Your wording should be your own.
Why feeding is hard: Mateo's mouth and nose are connected through the gap in the roof of his mouth, so he cannot make the gentle suction that pulls milk in. This is about a missing wall, not weak muscles, and his suck is fine.
What we will do: use a soft, squeezable (compressible) bottle so you deliver milk by gentle squeezing in rhythm with his sucking; he does not have to make a vacuum. Hold him more upright so gravity carries milk down the throat, which lowers milk coming out the nose and lowers the chance of milk going toward his airway.
What we will watch: his weekly weight gain. Steady weight gain tells us the plan is working and keeps him on track for safe surgery later.
Also due today: State the single anatomical reason (oronasal communication) in one sentence on the CER exit ticket.
How this was built, step by step
The finished product above did not appear all at once. Here is the path from the question to the turned-in work, so you can follow the same steps.
- 1Start from today's question: Why can't Mateo feed normally, and what can we change today to help him before any surgery?
- 2Work the Model and the Explore questions to reason it out before writing anything.
- 3Pull the specific evidence the product needs from the reading and any database you used.
- 4Write it up in the required format: Write Mateo's one-page feeding plan for his parents: (1) one sentence naming the anatomical reason in plain language, (2) the bottle type you recommend and why it removes the need for suction, (3) the position you recommend and the two problems it reduces, and (4) the single number you will watch each week to know the plan is working. Keep it warm.
- 5Check it against the rubric, then submit.
| Criterion | Proficient | Developing | Beginning |
|---|---|---|---|
| Complete | Every required part of the artifact is present and filled in. | Most parts are present, but one is missing or left blank. | Several parts are missing. |
| Accurate | The science and data are correct and match the evidence. | Mostly correct, with a small factual slip. | Key science or data is wrong. |
| Scientific reasoning (CER) | States a claim, backs it with specific evidence, and explains the reasoning. | Has a claim and evidence, but the reasoning is thin or missing. | Gives an answer with no evidence or reasoning. |
| Professional communication | Clear, organized, and labeled the way a clinician or scientist would write it. | Readable but disorganized or missing labels. | Hard to follow. |
| Submitted | Turned in the right way (Schoology for routine work) and confirmed. | Turned in, but in the wrong place or unconfirmed. | Not turned in. |
- CompleteProficient: Nothing is left blank: the model fills every part of "Write Mateo's one-page feeding plan for his parents: (1) one sentence naming the anatomical reason in plain language, (2) the bottle type you recommend and why it removes the need for suction, (3) the position you recommend and the two problems it reduces, and (4) the single number you will watch each week to know the plan is working. Keep it warm.".
- AccurateProficient: Every number and claim matches the case evidence.
- Scientific reasoning (CER)Proficient: It names a claim, cites the specific evidence, and explains the reasoning, not just the answer.
- Professional communicationProficient: It is organized and labeled like a real chart note.
- SubmittedProficient: It would be turned in on Schoology and confirmed.
