BSNC 3000 - Fluid, Lytes & PONV questions with
verified answers
Water and solute movement across between fluid compartments is
regulated by Ans✔✔-- The plasma membrane
- Capillary walls
Plasma membrane fluid movement is determined by Ans✔✔-- Osmosis
- Ion channels
- Carrier proteins
Capillary wall movement is determined by Ans✔✔-- Bulk flow
- Transcytosis
- Diffusion
Pressures that determine the movement of water and solute across
capillary walls Ans✔✔-- Blood colloid osmotic pressure
- Capillary hydrostatic pressure
Fluid & lyte balance Ans✔✔-The process of regulating ECV, osmolality,
and plasma concentration of lytes
Post op fluid losses Ans✔✔-- Vomiting, diarrhea
- Decreased intake (nausea)
- Blood loss
, - Suctioning/tubing
- Insensible losses (open surgery, tachypnea, wounds)
Post op fluid gain Ans✔✔-- IV, feeding tubes
- Third spacing (edema)
- Pericardial effusion
- Retention, obstruction
- PSR: ADH + aldosterone
- Inflammation
Sodium Ans✔✔-135-145
Most abundant ion in ECF -> determines ECF osmolality and ECV
balance.
Required for ATP generation, muscle contraction, depolarization
Gain (diet) and loss (urine, feces, sweat)
Hyponatremia effects on the cell Ans✔✔-Causes cellular swelling.
Makes depolarization slower so cells are less excitable
Hyponatremia causes Ans✔✔-Loss of Na
- Renal disease
