Fluid and Electrolytes Flashcards

1
Q

What is Fluid

A

Fluid is necessary for life and homeostasis. 60% of the human body is fluid. It exists in two compartments Extracellular (outside the cell) & Intracellular (inside the cell). 2/3 of the fluid is in the intracellular space.

Q

What are Electrolytes?

A

Active ions that carry charges.
Cations are Na+, Ca+, K+, Mg+
Anions are Cl-, HC03-, P04-
Concentrations vary depending on the compartment

Q

Lifespan Consideration for Infants and Children (Less than 2 yr.)

A

Infants have an increased risk of fluid and electrolyte imbalance because they have a higher respiratory rate & metabolic rate and immature kidneys. When infants are FVD their mucous membranes are dry, sunken soft spot and become lethargic.
***AT MOST RISK is preterm infants because of immature kidneys effect their ability to concentrate urine

Q

Lifespan Consideration for Older Adults

A

The thirst sensation in the elderly is blunted resulting in decreased fluid intake. Decrease body mass which decreases the amount of water in the body. Decreased renal reserve due to decrease in the number of nephrons.

TIGHT & CONTRACTED 
Decreased LOC 
Hypotension & bradycardia 
Diarrhea & hyperactive bowels  
Paralysis in extremities 
Decreased DTR
25

A
LOW & SLOW 
Cardiac dysthymias 
Shallow respirations 
Irritability 
Confused & Lethargic 
Flaccid limbs - skeletal muscle weakness
Hypoactive Bowel - paralytic ileus
27
Q

***REQUIRES FLUID RESTRICTION
29
Q

A

They are BESTIES! If sodium is LOW chloride is LOW

30

Fever

32
Q

Magnesium acts like LAW & ORDER in the muscle and keeps the peace. Required for calcium and vitamin D absorption. Magnesium and Calcium are BESTIES!

33
Q
