Why is acid reflux more common in pregnant women?
progesterone relaxes smooth muscle which prolongs gastric emptying time and increased GI motility
36
Why are pregnant women at higher risk of constipation?

42
How is oral medication admin affected with older adults?
decreased gastric acid secretion can cause pernicious anemia, iron deficiency anemia, malabsorption of calcium
43
Why are older adults more susceptible to dehydration?
ability to conserve water is reduced along with ability to respond to temp and thirst
44
How does liver size change with age?
-it decreases -usually <80yoa -influences medication metabolsim
45
How is renal function changed with age?

Incidence of _____________ increases with age
gallstones
47
Risk factors for constipation in older adults:

blood in vomit
56
Pica
eating non-edible foods

caves in
58
Protuberant abdomen
significant bulge
59
Hernia
protrusion of viscera through muscle wall
60
What is the next step after inspection in the abdominal exam?
auscultation - pa and pe can increase peristalsis and falsely interpret bowel sounds
61
If you hear a bruit...
avoid pa and pe
62
Which end of stethoscope do you use for bowel sounds?
diaphragm - bowel sounds are high pitched
63
Borborygmus
hyperperistalisis/stomach growling
64
How long must you listen before deciding bowel sounds are completely absent?
5 mins
65
Hyperactive Bowel Sounds
-loud -high-pitched -rushing -tinkling -signify increased motility -may indicate bowel obstruction
66
Which end of the stethoscope do you use for vascular sounds?
bell
67
Why shouldn't you palpate over a bruit?
risk of rupturing
68
__________ is heard over solid structure on percussion
dullness
69
_____________ is heard with gaseous distension
hyper-resonance
70
Voluntary guarding
occurs when the patient is cold, tense, or ticklish
71
Umbilical Hernia
appears 2-3 weeks after birth and is prominent when infant cries
72
Diastastis recti
separation of rectus muscles with a visible bulge along midline - more common in infants of African descent
73
When do you refer an umbilical hernia?
-larger than 2.5cm -continues to grow after one month -lasts more than 2 years (european) or 7 years (african)
74
Should you hear vascular sounds on abdomen of infant?
no
75
________ is not percussed in infants
