Exam 5: Protein: The Cellular Foundation

In patients with liver and kidney disease,increased levels of protein are recommended because these organs require continual cellular and tissue rebuilding that only protein can provide.

Each statement is true of the physiologic role of protein,except one.Which is the exception?

Each is a characteristic manifestation of necrotizing ulcerative gingivitis (NUG),except one.Which is the exception?

The physiologic role of proteins does NOT include:

Which is NOT recommended for a patient who wishes to lose weight and eat a more healthy diet?

In a 2-oz cooked serving,which food supplies the least protein?

Per kilogram of body weight,which group has the lowest RDA for protein?

The distinguishing feature of amino acids is the amine group.This nitrogen source is not present in carbohydrates but is present in fats and many vitamins.

Indispensable amino acids are essential for the body but are not required in the diet.Dispensable amino acids are not essential for the body but contribute to protein formation in various ways.

An edentulous patient dislikes eating meat.What substitutions could the dental hygienist suggest to provide the most protein intake?

Protein-energy malnutrition (PEM)may be responsible for increased incidence of noma and necrotizing ulcerative gingivitis (NUG)because these conditions are associated with depressed immune responses caused by nutritional deficiencies.

Which food is most likely to contribute to protein deficiency?

Patients with periodontal disease might require increased protein intake because the physiologic response to inflammation and infection can negatively affect protein synthesis.

The intake of 193 g/day of protein is the highest level recommended because consumption above this level can jeopardize adequate intakes of nutrients from other food sources.

Poor nutrition results in delayed eruption and exfoliation of deciduous teeth and increased dental caries.Increased caries susceptibility in at-risk children may be related to changes in salivary composition caused by malnutrition.

Amino acids combine with each other to form polypeptides,which are components of food and body proteins.The number of amino acids in a protein varies between 10 and 25,but each protein has a specific number.

A patient presents the following meal pattern of a typical day.This individual is most likely what type of vegetarian? *Breakfast 1 medium orange Cup oatmeal Cup sliced almonds 1 tsp margarine 1 cup soy milk *Lunch 1 cup cooked black beans 1 6-inch tostada 2 slices of tomato 1 leaf of lettuce 1 medium banana 1 cup soy milk *Dinner 1 cup bean soup 1 cup raw spinach leaves 1 slice rye bread 1 tsp margarine 1 cup pears 1 cup soy milk

Tissue building,maintenance,and repair are physiologic roles of proteins and carbohydrates because both nutrients provide essential amino acids necessary for these functions.

The type of vegetarian most at risk for nutrient deficiencies is the:

Prognosis for a protein-deficient patient undergoing periodontal surgery is reduced because excess nitrogen reduces the ability of the periodontium to withstand stress of surgery.
