Physio Lab #9

Question 1

what is it important for healthcare workers to know about physical activity?

Answer 1

the impact of physical activity on energy metabolism

Question 2

what does energy metabolism entail?

Answer 2

the digestion, absorption, uptake, and storage of energy substrates

Question 3

what is this lab going to do

Answer 3

review the impact of physical activity on energy metabolism (digestion, absorption, uptake, storage) through plasma glucose testing under conditions of rest, pre-activity, and post-activity consumption

Question 4

what are the conditions that we are testing under plasma glucose?

Answer 4

rest, pre-activity, and post-activity consumption

Question 5

why must volunteers fast and how long

Answer 5

3 hours before (water only)

Question 6

why no diet drinks?

Answer 6

because sweet taste will interfere with the tests, whether or not the body absorbs calories

Question 7

why should you not participate in this exercise

Answer 7

blood born disease, blood glucose reguation disorder, clotting disorder

Question 8

what should those not participating in the testing do

Answer 8

record information, prepare equipment, other tasks

Question 9

when to wear gloves

Answer 9

when handling someones blood ALWAYS wear globes

Question 10

what to do when we suspect we are getting anomalous readings from the glucose reading

Answer 10

see the TA

Question 11

when must lancets be disposed of

Answer 11

carefully/immediately after use

Question 12

what to do if you open a new bottle of control solution

Answer 12

write the day you opened it on the bottle

Question 13

who is in charge of control solutions and checking glucometers?

Answer 13

the TA

Question 14

what to do the first time you use a new test drum (test strip container)

Answer 14

run a control

Question 15

when should test strip drums should be used by?

Answer 15

90 days after opening

Question 16

why are we washing our hands in warm soapy water before using lancets

Answer 16

warm water = stimulates blood flow

Question 17

then after washing, how long should the arm hang on the side and why?

Answer 17

30 seconds so the blood can flow to the fingertips

Question 18

when should we squeeze our finger and how long

Answer 18

before pricking for 3 seconds

Question 19

what to be careful of when using lancents

Answer 19

dont squeeze the finger too hard

Question 20

when should blood be applied to the test strips

Answer 20

immediately

Question 21

where should anything that contacts blood other than SHARPS go

Answer 21

the biowaste bag

Question 22

where do sharps do

Answer 22

sharps container

Question 23

what do you wipe down the glucometer with after using?

Answer 23

alcohol

Question 24

why is homeostatic maintenance of plasma glucose critical?

Answer 24

because the brain is almost entirely dependent upon glucose as an energy substrate

Question 25

what does glucose homeostasis beginw ith

Answer 25

feedforward reflexes following ingestion and digestion by the GI tract

Question 26

what is glucose regulated by once in the plasma

Answer 26

antagonistic control of the pancreatic hormones insulin and glucagon

Question 27

for the exercise, what should the metronome be set at?

Answer 27

75 bpm

Question 28

what exercise is happening?

Answer 28

right foot on step, then left foot, right foot down, left foot down (if stress, try another procedure)

Question 29

mouth enzyme/digestive aids; substrate; absorption

Answer 29

saliva carbs none

Question 30

stomach enzyme/digestive aids

Answer 30

HCl, pepsinogen, gastric lipase, mucous, gastrin, histamine

Question 31

stomach substrates/products

Answer 31

protein, fats

Question 32

stomach absorption

Answer 32

lipid soluble substances like alcohol and aspirin

Question 33

small intestine enzymes

Answer 33

enzymes, mucus, bicarbonate, bile, hormones

Question 34

small intestine substrate/products

Answer 34

polypeptide, carbs, fats, nucleic acids,

Question 35

small intestine absorption

Answer 35

amino acids, small peptides, monosaccharides, fatty acids, monoglycerides, cholesterol, nitrogen

Question 36

in what form is glucose stored? in which organs

Answer 36

glycogen in the liver, muscles, adipose tissue

Question 37

insulin: stimuli, receptor, efferent

Answer 37

s: eating, carbs in lumen, GI abdominal dissention r: a cells in pancreas, CNS, endocrine cells e: GLP-1, GIP, inc para, dec symp

Question 38

insulin: effectors, immediate response, overall response

Answer 38

effectors: liver, muscle, adipose immediate: inc glycolysis, glycogenesis, lipogenesis, protein synthesis, glucose transport overall: dec plasma glucose

Question 39

glucagon: stimuli, receptor, efferent

Answer 39

stimuli - dec plasma glucose, dec plasma amino acid receptor - a+b ceels of pancrease efferent - inc glucagon and dec insulin

Question 40

glucagon: effector, immediate response, overall response

Answer 40

effector: liver, muscle, adipose immediate response: glycogenesis, gluconeogenesis, ketones overall - inc plasma glucose

Question 41

how is glucose transported from the plasma into most cells?

Answer 41

GLUT transporter

Question 42

why GLUT transporter?

Answer 42

because they are reversible and can move glucose in and out of cells easily

Question 43

which gastrointesinal hormone is upregulated by presensce of glucose in the small intestine

gastric inhibitory peptide

Question 44

which metabolic hormone is upregulated by gastric inhibitory peptide

insulin
