Fluids & Electrolytes
Fluid found between cells but outside blood vessels.
Interstitial fluid
Movement of solutes from high to low concentration.
Diffusion
Normal blood pH range
7.35–7.45
Route that delivers medication directly into a vein.
IV
Formula used to calculate a medication volume.
Desired ÷ Have × Volume
The largest percentage of total body water is found here
Intracellular fluid
Movement of water across a semipermeable membrane toward higher solute concentration.
Osmosis
The body's principal buffer anion
Bicarbonate
Which gluteal muscle site can be used for an intramuscular (IM) medication injection?
What is the dorsogluteal site?
Formula for calculating an IV drip rate
Volume × drop factor ÷ time in minutes
Principal cation in extracellular fluid
Sodium
Process that uses energy to move substances against a concentration gradient
Active transport
The body's fastest response to an acid-base disturbance.
Bicarbonate/buffer system
an acid-base disturbance. A: Bicarbonate/buffer systemRoute with very slow absorption and the least systemic effect.
Intradermal
100 mL must infuse over 30 min using a 15 gtt/mL set. Calculate the drip rate
50 gtt/min
Force that pushes water out of capillaries and into interstitial space.
Hydrostatic pressure
A solution with a greater solute concentration than another solution is described as this.
Hypertonic
A patient with metabolic acidosis begins breathing faster and deeper. The body is trying to remove this.
CO₂
You are unsure of a medication dose. This should be your next action.
Contact medical direction
You have 200 mg in 10 mL and need to give 50 mg. How many mL?
2.5 mL
Fluid shifts out of effective circulation and collects in another space, such as with peritonitis or bowel obstruction
Third spacing
Mechanism responsible for moving sodium out of a cell and potassium into it
Sodium-potassium pump/active transport
During metabolic acidosis, the kidneys help compensate by retaining this substance
Bicarbonate
After unsuccessful peripheral IV attempts, a critically ill patient still needs immediate vascular access
IO access
250 mL must infuse over 30 min using a 10 gtt/mL set. Calculate the drip rate
83 gtt/min (rounded)
