Small Animal Nursing Flashcards
Normal fluid loss occurs in 3 ways:
Excretion, respiration, sweating/milk
Abnormal fluid loss can occur in 4 ways
Vomiting, diarrhea, panting, polyuria
Normal urine production is _______/kg/hour
1-2ml
Semi-dry mucus membranes and a mild loss of skin tugor means the animal is ___% dehydrated
5
Moderate loss in skin tugor, dry mucus membranes, weak or rapid pulse, sunken eyes mean the animal is ___% dehydrated
8
What symptoms accompany severe/10% dehydration?
Tachycardia, tacky mucus membranes, weak pulse, hypotension, altered state of consciousness, severe sunken eyes
What is the most commonly used type of fluid for replenishing interstitial deficits?
Isotonic crystalloid (LRS, Plasmalyte, Normosol-R)
Give an eample of a hypotonic crystalloid fluid solution
5% Dextrose in water
Give an example of a hypertonic crystalloid fluid solution
7% Hypertonic Saline
A Colloid fluid is a solution containing ___ or ___ molecules. What is its purpose?
protein or starch. to remain in the intravascular space and expand its volume
Name 3 situations when you would use a Colloid fluid solution
When crystalloids are not effectively improving blood volume; large patients, emergency surgery, large fluid loss
Give an eample of a synthetic colloid fluid solution
Hetastarch
Give an example of a natural colloid fluid solution
Plasma or albumin solution
For hypovolemic, shock, or severely dehydrated patients _____ fluids should be administered at ______ml/kg IV for cats and _____ml/kg IV for dogs
Isotonic crystalloids. 50ml/kg for cats and 80ml/kg dogs
When an animal is in shock, calculate the shock dose and give them ___% bolus
25%
How do you calculate the replacement fluid amount needed for a dehydrated animal?
%dehydration x bodyweight (kg) x 10
How do you calculate the daily fluid requirement for an animal with dehydration?
replacement + maintenance + ongoing losses
Maintenance fluids for cats and dogs are:
Cats: 2-3ml/kg/hour
Dogs: 2-6ml/kg/hour
Why would we not use LRS as maintenance fluids?
Maintenance fluids are indicated for patients not eating/drinking and LRS contins more sodium and less potassium than the patient requires
What are 4 existing conditions that would contraindicate the use of fluid therapy?
Pulmonary contusions, pulmonary edema, brain injury or congestive heart failure
