What is the best action for a nurse to take on finding a
client's serum chloride level is 101 mEq/L? - Correct Answer
✅Urge the client to drink more water.
Notify the primary health care provider.
Assess the client's deep tendon reflexes..
Document the finding as normal
The normal range for serum chloride levels is between 98 and
106 mEq/L. No action beyond confirming documentation is
needed.
What effect does the nurse expect that an infusion of 200 mL
of albumin will have immediately on a client's plasma osmotic
and hydrostatic pressures? - Correct Answer ✅Decreased
osmotic pressure; decreased hydrostatic pressure
Decreased osmotic pressure; increased hydrostatic pressure
Increased osmotic pressure; increased hydrostatic pressure
Increased osmotic pressure; decreased hydrostatic pressure
The addition of albumin to the plasma would add a colloidal
substance that does not move into the interstitial space.

Thus, the osmotic pressure would immediately increase. Not
only does the additional 200 mL add to the plasma
hydrostatic pressure, but also the increased osmotic pressure
would draw water from the interstitial space, increasing the
plasma volume and ultimately leading to an increased
hydrostatic pressure in the plasma volume.
What responses does the nurse expect as a result of infusing
500 mL liter of a 3% saline intravenous solution into a client
over a 1 hour time period? - Correct Answer ✅A. Plasma
volume osmolarity increases; blood pressure increases
B. Plasma volume osmolarity decreases; blood pressure
increases
C. Plasma volume osmolarity increases; blood pressure
decreases
D. B. Plasma volume osmolarity decreases; blood pressure
decreases
Rationale:
A 3% saline solution is hypertonic to body fluids and would
immediately increase the osmolarity of the plasma volume,
making it somewhat hypertonic to other body fluids. Not only

does the 500 mL increase the plasma volume to raise blood
pressure, the increased osmolarity of the plasma would cause
the interstitial fluid to move into the plasma volume,
contributing to blood pressure increase.
Which clinical indicators are most relevant for the nurse to
monitor during IV fluid replacement for a client with
dehydration? Select all that apply. - Correct Answer ✅A.
Blood pressure
B. Deep tendon reflexes
C. Hand-grip strength
D. Pulse rate and quality
E. Skin turgor
F. Urine output
Rationale:
The most important body fluid compartment to maintain for
function is the plasma volume of circulating blood. The most
reliable indicators for effectiveness of IV fluid replacement to
increase this volume are blood pressure and pulse. Urine
output is also very sensitive to changes in plasma volume
and is a reliable indicator of adequacy of fluid replacement
