Study Notes

Energy and Digestion

Main energy source for the body is glucose.
Digestion begins in the mouth.
Emptying of the stomach into the small intestine is controlled by the pyloric sphincter.

Absorption and Nutrient Reactions

Absorption of nutrients and water-soluble vitamins mainly occurs in the small intestine.
Catabolic reactions take place in cells after nutrients are digested, absorbed, and transformed.

Eating Disorders

Self-imposed starvation is known as anorexia nervosa.
Bulimia nervosa is characterized by laxative abuse, binge eating, followed by purging.

Dietary Components

Predominant component of a vegetarian diet is plant-based foods.
Risk factors associated with malnutrition include age, illness, and inadequate food intake.

Saliva and Nutrition Therapy

Main function of saliva in digestion is to begin the breakdown of carbohydrates and lubricate food for swallowing.
Parenteral nutrition (PN) therapy is beneficial in scenarios where patients are unable to consume food orally.

Diet Types and Preferences

A soft diet includes easily digested foods like pastas, moist meats, and canned vegetables.
Preferred method to meet nutrition needs if a patient cannot swallow is enteral nutrition (EN).

Nutrition Formulas and Conditions

Basic Total Parenteral Nutrition (TPN) formula primarily consists of carbohydrates, proteins, and fats.
A gluten-free diet eliminates wheat, oats, rye, barley, and their derivatives.

IV Nutrition Support

Parenteral nutrition support is provided intravenously.
Varied caloric recommendations are necessary for patients with specific metabolic demands.

BMR and MNT Goals

Basal metabolic rate (BMR) refers to the amount of energy expended while at rest.
Main objective of Medical Nutrition Therapy (MNT) is to manage medical conditions through improved nutrition.

Healthy People 2030 Objectives

Increasing consumption of fruits, vegetables, and whole grains aims to improve overall health.
Reducing added sugars, saturated fats, and sodium is crucial to prevent chronic diseases.
Aiming to increase calcium, potassium, and vitamin D intake supports bone and cardiovascular health.
Reducing iron deficiency among children aged 1 to 2 is vital for proper growth and development.

Food Security and Nutrition Goals

Increasing schools that do not sell unhealthy foods promotes better eating habits in children.
Eliminating very low food security among children is important for their physical and mental well-being.
Reducing household food insecurity aims to enhance the nutritional quality of family diets.
Decreasing the proportion of adults with high blood pressure is necessary to reduce cardiovascular risk.

Parenteral Nutrition (PN) Details

Goal of PN therapy is to provide necessary nutrition to patients unable to eat normally.
Avoid using admixture if oil droplets or an oily layer is visible to ensure safety.
A central venous catheter (CVC) is required for PN with greater than 10% dextrose to prevent complications.
An infusion pump regulates the delivery rate of PN solutions.
IV solutions of less than 10% dextrose can be administered via a peripheral vein in appropriate situations.

GI Tract Use and Catheters

Risk associated with disuse of the gastrointestinal (GI) tract includes atrophy and loss of function.
Intravenous fat emulsions support a patient’s calorie needs through supplemental fat.
A standard catheter is used for short-term nutritional needs in patients.
It is essential to confirm placement and patency of a PICC line before flushing and using it.
