nutrition diets

Week number six lecture covering medical math and nutritional concepts.
Goals for the session: review lecture content, med math, concept math.
Exam three will include material covered in this week, scheduled for week twelve.
Emphasis on practice and understanding nutrition—an area where students generally struggle.

Nutrition-related questions may be detailed and complex.
Example question: "This patient has scurvy; what food would you recommend?" Options: broccoli, kiwi, potato, fish.
- Understanding that scurvy is caused by vitamin C deficiency is crucial.
- Identify which of the foods has the highest vitamin C content, noting that broccoli is often a better source than kiwi or fish.
Patients with celiac disease will have questions asking about foods they cannot eat.

Utilize dynamic quizzing to practice nutrition questions, including easy, medium, and hard levels.
Pay attention to rationales behind answers for better understanding.

Waist-Hip Circumference: Different standards for males and females.
Body Mass Index (BMI): Recognize and memorize the ranges for underweight, normal weight, overweight, and obese categories.
Arm Circumference: Another measure to assess nutritional status.

Understanding various nutrition screening tools and their importance in assessing a patient's nutritional needs.
Ensure complete answers during patient screenings.
Questions to ask patients include:
- 24-hour food recall.
- Medical history, focusing on conditions like GERD and any food allergies.

Chewing: Offer small, soft foods to assess ability without risk of choking.
Swallowing: Monitor for any coughing, change in voice, or hesitation while swallowing.
Pay attention to indications of unintentional weight loss.

Nutritional needs vary significantly based on age (infants vs. elderly) and life stages (pregnancy, lactation).
Importance of Folic Acid for pregnant women to prevent neurological issues in infants.

Prealbumin levels: Best indicator of malnutrition. Levels less than 16 indicate malnutrition.
Understanding how protein intake affects recovery and healing.

Main sources of protein include meats (best source) and plant-based sources like beans and grains (combine for complete amino acid profile).
Importance of beans and rice together to form a complete protein for vegetarians.

Hemoglobin and Albumin: Need to be monitored along with vital signs and glucose levels.

Clear Liquid Diet: Water, chicken broth, apple juice—considered clear but not all liquids classified as clear.
Full Liquid Diet: May include dairy products, depending on guidelines.

Pureed Diet: Designed for those unable to chew—food must be smooth.
Soft Mechanical Diet: For those who can manage soft foods like mashed potatoes or scrambled eggs.
Low Residual Diet: Minimal fiber diet for patients needing bowel rest—specifically avoid high fiber foods.
Therapeutic Diets: Tailored to specific conditions (e.g., low sodium for CHF, increased calories for underweight patients).

Encourage patient involvement in selecting and consuming food where possible.
Important to provide oral care after meals to prevent respiratory issues.
Understanding and compliance with feeding systems, distinguishing between open and closed systems (TPN).

Monitor for aspiration risk, diarrhea, constipation, and skin breakdown related to feeding devices.

Patterns in patient feeding strategies are crucial for recovery and nutrition.
In patient care, always aim to maintain dignity and promote independence in eating.
