Fluids Flashcards
The healthcare provider orders a hypertonic crystalloid IV solution for a 70-year-old patient with cerebral edema. Which assessment should the nurse report immediately to the provider?
a) Improved BP, increased urinary output, and stable vital signs.
b) Hyperglycemia, decreased urinary output, and increased level of conciousness.
c) Thirst, dry mouth, cool extremities, and decreased urinary output/
d) headache, irritability, confusion, widening of pulse pressure, and decreased level of conciousness.
d) headache, irritability, confusion, widening pulse pressure, and decreased level of conciousness.
A pt. is receiving fluid replacement. The nurse’s health teaching with the pt. includes which suggestions? (Select all that apply).
a) Measure weight daily.
b) Know that thirst means a mild fluid deficit.
c) Monitor fluid intake.
d) Avoid the use of calcium supplements.
e) Monitor output.
a, b, c, e
A pt. gained 10 lbs. in 2 days. It is determined that the weight gain is caused by fluid retention. The nurse correctly estimates the weight gain may be equivalent to approximately how much fluid?
a) 2 L
b) 4 L
c) 10 L
d) 11 L
b) 4 L
Definition:
Solutions that contain protein or other large molecular substances that increase osmolarity without dissolving in the solution.
Colloids
Definition:
Solutions that contain fluids and electrolytes and are able to freely cross the capillary walls.
Crystalloids
Definition:
Substances that separate or dissociate into ions (charged particles) in a solution; they are abundant in both ICF and ECF.
Electrolytes
Definition:
Fluid contains more particles than water.
Hyperosmolar
Definition:
Fluid contains fewer particles than water.
Hypo-osmolar
Definition:
Solutions that exert less osmotic pressure than ECF, which allows water to move into the cell.
Hypotonic
Definition:
Fluid that has the same proportion of weight of particles and water.
Iso-osmolar
Definition:
Solutions that have the same approximate osmolality as ECF or plasma. Water does not enter or leave the cell.
Isotonic
Definition:
Solutions that exert greater osmotic pressure than ECF, resulting in a higher solute concentration than the serum.
Hypertonic
Definition:
The number of solutes in a solution; a unit of measurement.
Osmole
Definition:
The number of osmoles per kilogram of water. Expressed as mmol/kg or mOsm/kg.
Osmolality
Definition:
The number of osmoles in 1 L of solution; Expressed as mmol/L or mOsm/L.
Osmolarity
