List two ways to assess a patient’s level of dehydration

• Skin tent

• MM moisture

Which of the following is the least important when monitoring a patient receiving IV fluids?

• urine output 

• oral water intake 

• body weight 

• BP 

oral water intake 

Rapid changes in osmolality can cause:

• Dehydration

• Anemia

• Cerebral edema

• Decreased urination

cerebral edema

T/F: Synthetic colloids are safe and should be used in all cases of hypotension

false

Which of the following is not a common sign of fluid overload?

• nasal discharge

decreased urination 

Calculate the hourly maintenance fluid rate for a dog weighing 16kg

16kg x 60= 960 ml/day/24=0.0417 mL/day=40 ml/hr 

What is a normal dog’s urine production rate?

• 2-4ml/kg/day

• 0-0.5ml/kg/day

• 3-5ml/kg/day

• 1-2 ml/kg/day

1-2 ml/kg/day

Briefly describe the effect hypertonic saline has when administered IV

it draws fluids from the interstitial and intracellular spaces which then goes to the IV spaces
this causes rapid plasma volume expansion

When crystalloid fluids are administered, what percentage of the volume delivered will ultimately remain in the intravascular space?

• 25 %

• 35 %

• 50 %

• 75 %

25%

Calculate the daily maintenance fluid rate for a cat weighing 4.2kg

4.2 x 50=210 ml/day 

Cats can be 40-60 ml/kg/day soo I went half way :)
