Module 11: 5 CNA Nutrition Dialogues for English Learners

Dialogue 1: Morning Shift Report

Setting: Two CNAs discussing a patient’s dietary needs

Sarah (Day CNA): Good morning, Maria. How was Mrs. Johnson overnight?

Maria (Night CNA): She had some issues. She’s on a low sodium diet, but she complained about the bland food. Also, I noticed signs of dehydration – her skin was dry and she had decreased urine output.

Sarah: Did you check her intake and output records?

Maria: Yes, her fluid intake was very low. The dietician recommended we force fluids today. She needs at least 2000ml.

Sarah: I’ll make sure she gets plenty of water and juice. Any problems with aspiration?

Maria: No, but watch her closely. She has mild dysphagia, so make sure she sits upright when drinking.


Dialogue 2: Helping with a Therapeutic Diet

Setting: CNA explaining diet restrictions to a patient

CNA (David): Mr. Rodriguez, I have your lunch tray. Remember, you’re on a low fat diet because of your heart condition.

Patient: This looks different from what I usually eat. What’s a low fat diet?

David: It means we limit foods high in fats and cholesterol. Your meal has grilled chicken, steamed vegetables, and brown rice – all good sources of protein and carbohydrates without too much fat.

Patient: Can I have butter on my bread?

David: I’m sorry, but butter is high in fat. However, you can have this small amount of margarine. It’s important to follow your therapeutic diet to help your heart stay healthy.

Patient: I understand. Will this help with my digestion too?

David: Yes, lighter foods are often easier to digest. The fiber in these vegetables will also help your digestive system.


Dialogue 3: Dealing with Eating Difficulties

Setting: CNA assisting a patient who has trouble swallowing

CNA (Jennifer): Mrs. Chen, I see you haven’t touched your breakfast. Are you having trouble eating?

Patient: Yes, it’s hard to swallow. Sometimes I feel like food gets stuck.

Jennifer: That sounds like dysphagia. Let me get you a clothes protector first, and then I’ll help. Have you been pocketing food in your cheeks?

Patient: Sometimes. What does that mean?

Jennifer: Pocketing means food stays in your mouth instead of being swallowed. It can be dangerous. I’m going to give you thickened liquids instead of regular water – they’re easier to swallow safely.

Patient: Will I always have to eat this way?

Jennifer: The speech therapist will evaluate your swallowing. For now, we want to prevent aspiration – that’s when food or liquid goes into your lungs instead of your stomach.

Patient: That sounds scary.

Jennifer: Don’t worry. We’ll take good care of you. I’ll make sure you get proper nutrition with foods that are safe for you to swallow.


Dialogue 4: Monitoring Fluid Balance

Setting: CNA discussing hydration with a supervisor

CNA (Kevin): I’m concerned about Mr. Williams in room 205. His intake and output numbers don’t look right.

Supervisor: What did you observe?

Kevin: His fluid intake is very low, only 800ml yesterday. He shows signs of dehydration – dry mouth, concentrated urine, and he seems confused.

Supervisor: Any edema in his legs or face?

Kevin: No edema, but I did notice diaphoresis during the night. He was sweating a lot, which could increase fluid loss.

Supervisor: Good observation. Has he been able to take his essential nutrients?

Kevin: He’s been refusing meals. Yesterday he had anorexia – no appetite at all. I’m worried about over-hydration if we push fluids too quickly though.

Supervisor: You’re right to be careful. Let’s start with small, frequent sips and contact the doctor about possible intravenous infusion if he doesn’t improve.


Dialogue 5: Tube Feeding Discussion

Setting: CNA training session about enteral feeding

Instructor: Today we’ll discuss enteral feeding. Who can tell me what that means?

Student CNA (Alex): Is that feeding through a tube?

Instructor: Correct! Enteral feeding is nutrition given through the digestive system using tubes. What types of tubes might we see?

Student CNA (Lisa): Nasogastric tubes go through the nose to the stomach.

Instructor: Right! And what about more permanent options?

Alex: Gastrostomy tubes go directly into the stomach through the abdomen. And PEG tubes – that’s percutaneous endoscopic gastrostomy – are a type of gastrostomy tube.

Instructor: Excellent! Now, what’s gavage?

Lisa: That’s the process of giving nutrition through the tube, right?

Instructor: Yes! When patients can’t eat normally, we use these methods to ensure they receive proper nutrients, vitamins, and minerals. We always measure the feeding with a graduate – that’s a measuring container – to track exact amounts.

Alex: What if someone needs nutrition but their digestive system isn’t working?

Instructor: Great question! That’s when we might use parenteral nutrition – feeding through an IV. Total Parenteral Nutrition or TPN provides complete nutrition directly into the bloodstream.
