Test 3 Flashcards
How do you do a skin turgor test in horses?
pinch skin on lateral side of neck
How do you do a skin turgor test in small animals?
pinch skin on lateral chest
What does a normal skin turgor test look like?
skin returns promptly to normal position 1 sec or less
A snap back with a >1 sec return means what?
> 5% dehydration
A snap back with a >8 sec return means what?
severe dehydration
Skin turgor is less reliable in what kind of patient?
obese
Thin horses and older than 15 years have what kind of skin snap?
delayed regardless of hydration
CRT is more accurate for assessing hydration than what?
skin turgor
CRT reflects cardiac output which is directly affected by what?
hydration status
Prolonged CRT usually means what?
low CO, most commonly result of inadequate hydration
What is a normal CRT?
<2.5 sec
What is an abnormal CRT?
> 2.5 sec
What is the CRT for a severely dehydrated animal?
5-8 sec
What do dry, tacky MM mean?
dehydration unless they have been panting
What do moist MM mean?
normal
What do slick MM mean?
nausea
What do pale MM mean?
lack of blood flow. Could be due to dehydration, hypovolemia
What does yellow urine mean?
concentrating=dehydration
Rapid weight gain means what?
possibility of overhydration or urine output has suddenly stopped
Rapid weight loss means what?
dehydrated, blood loss, urine losses increased over fluid input
What is a lung characteristic of pulmonary edema?
“crackles” sounds “wet”, “gurgling”
What can cause the lungs to sound “wet”?
too many fluids, can occur with congestive heart failure
Decreased lung sounds can happen when?
obesity, effusions and hypovolemia
What does a bounding pulse strength mean?
overhydrated and low BP
What does a thready pulse strength mean?
dehydrated and low BP
Rapid HR may mean what?
hypovolemia, hypoxia
Slow HR may mean what?
hypovolemia
Cool limbs indicate what?
hypovolemia (dehydration)
What does is mean when the eyelid and scleral conjunctiva will be puffy and fluid filled?
edema
What can Chemosis be an indicator of?

A Doppler uses what to audibly locate the arterial pulse?
ultrasound crystal and monitor
BP cuff determines what?
systolic, diastolic, mean arterial pressures
You can program BP cuffs to do what?
record at intervals
