24

________ refers to all of the biochemical reactions within the cells of the body.

Metabolism

25

_________ is the building of more complex biochemical substances by synthesis of nutrients.

Anabolism

26

_________ is the break down of biochemical substances into simpler substances and occurs during physiological states of negative nitrogen balance.

Catabolism

27

An energy-dependent process whereby particles move from an area of greater concentration to an area of lesser concentration. A special carrier moves the particle across the cell membrane.

Active transport

28

The force by which particles move outward from an area of greater concentration to lesser concentration. The particles do NOT need a special carrier to move outward in all directions.

Passive diffusion

29

Movement of water through a membrane that separates solutions of different concentrations. Water moves to equalize the concentration pressures on both sides of the membrane.

Osmosis

30

Engulfing of large molecules of nutrients by the absorbing cell when the molecule attaches to the absorbing cell membrane.

Pinocytosis

31

______________ present evidence based criteria for an acceptable range of amounts of vitamins and nutrients for each gender and age group.

Dietary reference intakes (DRIs)

32

________ provides an estimate of what a person should weigh.

Ideal body weight (IBW)

33

__________ measures weight corrected for height and serves as an alternative to traditional height-weight relationships.

Body mass index (BMI)

34

______ refers to difficulty swallowing.

Dysphagia

35

Ingestion of a diet balanced with carbs, fats, proteins, vitamins, and minerals provide the essential nutrients to carry out the normal physiological functioning of the body throughout the life span.

True

36

Through digestion food is broken down into its simplest form for absorption. Digestion and absorption occur mainly in the small intestine.

True

37

Guidelines for dietary change recommend reduced fat, saturated fat, sodium, refined sugar, and cholesterol and increased intake of complex carbohydrates and fiber.

True

38

Because improper nutrition affects all body systems, nutritional assessment includes a review of total physical assessment.

True

39

Enteral feedings are for patients who are unable to ingest food but are able to digest and absorb food in the gastrointestinal tract.

True

40

EN protects intestinal structure and function and enhances immunity.

True

41

TPN supplies essential nutrients in appropriate amounts to support life through the administration of a concentrated nutrient solution into the superior vena cava near the right atrium of the heart.

True

42

MNT is a recognized treatment modality for both acute and chronic disease states.

True

43

One of the most important responsibilities of a nurse administering enteral feedings is to take precautions to prevent patients from aspirating feeding formula.

True
