Q

Reasons why nutritional science is applied to nursing
care: RCA

A
  1. The recognition of the role of nutrition in preventing
    diseases or illnesses;
  2. The concern for adapting food patterns of
    individuals to their nutritional needs within the framework
    of their cultural, economic and psychological situations
    and styles; and
  3. The awareness of the need in specified disease
    states to modify nutritional factors for therapeutic
    purpose.

Q

Composed mostly of water, inorganic ions, and
carbon-based molecules, make up over 70% of
cell mass. Nutrition studies their growth and
development, as they form the human body.
Despite differences in size, composition, and
function, all cells can move, grow, ingest food,
excrete waste, respond to the environment, and
reproduce.

    substances entering & leaving the cells.
  • The membrane protein serves as pumps, gates,
    receptors, energy transducers & enzymes.
30
Q

The proteins in the cell membrane from pores or
openings to permit passage of materials by:

A

● Acting enzymes to help substances enter the
cell
● Acting as antigen markers to identify the cell as
“self”
● Serving as receptor sites for hormone

31
Q

A watery solution of mineral, gases & organic
molecules found between the cell membrane &

AUTOLYSIS

A

a process in which intracellular components (inc organelles) are digested due to the cellular degeneration or injury

53
Q

BONE RESORPTION

A

CILIA AND FLAGELLA

56
Q

_____ is shorter than _______

A

CILIA IS SHORTER THAN FLAGELLA

57
Q

The largest of the organelles; surrounded by a nuclear envelope composed of two membranes which enable communication between the vesicles & the cytoplasmic matrix. A continuous channel between this & ER is thus possible.

A

NUCLEUS

58
Q

Contains the genetic material (DNA) of the cell.
Due to the DNA content, it is the initiator & regulator of most cellular activities.

A

NUCLEUS

59
Q

Site of the synthesis of new DNA molecules (replication) & of RNA molecules (transcription).

A

NUCLEUS

60
Q

The control center of the cell that contains the chromosomes. The 46 chromosomes of the human cell are long threads called chromatin that are made of DNA & protein.
