CORRECT ANSWERS
GRADED A+ LATEST 100%
GUARANTEED PASS
1. Maintenance - CORRECT ANSWER-a. Replaces the ongoing losses of water and electrolytes
under normal physiologic conditions
b. This is usually done when the patient is not expected to eat or drink for a prolonged period of
time i.e. perioperatively or on a ventilator
c. The goal of therapy is to preserve water, electrolyte balance and provide some nutrition
d. If the period of time is expected to go beyond 1-2 weeks, then parenteral or enteral nutrition
should be started
a. Typical maintenance fluid - CORRECT ANSWER-i. D51/2NS with 20KCL
1. Electrolyte free water replacement is less than 1L a day
2. Sodium content is 3.4g which is similar to what is given in the hospital diet
3. Dextrose provides 400 calories which is enough to prevent catabolism
4. Continue this fluid ***unless
a. Sodium decrease, switch to D5NS
b. Sodium rises, switch to D5 1/4NS
, c. Serum potassium falls- add more potassium
1. Most people will be around 125ml/hr
1. Baseline Fluid Requirements - CORRECT ANSWER-a. Non 70kg adult
i. For the first 10 kg of body weight: 100mg/kg/day (1000ml) plus
ii. Second 10kg of body weight: 50mg/kg/day (500ml) plus
iii. For the weight above 20kg: 20ml/kg/day
a. This can be used to calculate the rate of maintenance fluids for a 24-hour period - CORRECT
ANSWER-i. For a 120kg adult
ii. First 10kg= 1000ml
iii. Second 10kg= 500ml
iv. Remaining 100kg = 2000ml
v. Total baseline fluid requirements is 3.5L
vi. 3.5L divided by 24 hours= 145ml/hr which would be a reasonable rate to give maintenance
fluid
1. Replacement - CORRECT ANSWER-a. Corrects existing water and electrolyte deficits. Deficits
result from GI losses, urinary losses, skin losses, bleeding or third space sequestration
a. Rate of replacement - CORRECT ANSWER-i. Must be given at a rate to compensate for
estimated losses (insensible, urine, and other source for loss)
1. Estimated insensible losses are 30-50ml/hr
General rule set IV rate at 50-100ml/hr greater than estimated fluid loss
a. Choice of Fluid - CORRECT ANSWER-i. Depends on the type of fluid that has been lost and any
concurrent electrolyte disorders
