Q1 QUESTION 1 OF 104
When the client's serum sodium level is 120 mEq/L, the priority nursing assessment is to
monitor the status of which body system?
RESPONSE
Neurological
RATIONALE
Hyponatremia, indicated by a serum sodium level of 120 mEq/L, directly impacts the central nervous
system due to osmotic shifts in brain cells. This can lead to cerebral edema and neurological
dysfunction. Therefore, assessing the neurological system is the priority nursing intervention.
Q2 QUESTION 2 OF 104
The majority of body fluid is located in which area?
RESPONSE
Correct Answer:
Intracellular
RATIONALE
Intracellular fluid constitutes the largest compartment of total body water, representing
approximately two-thirds of the body's fluid volume. This fluid is contained within the cell
membranes of all body cells. Extracellular fluid, which includes interstitial and plasma fluid,
comprises the remaining one-third.
Q3 QUESTION 3 OF 104
The nurse recognizes that the client, on the basis of the imbalance that is present, will
require fluid replacement with isotonic solution. One of the isotonic solutions that may be
ordered by the physician is:
Page 2
, RESPONSE
Correct Answer:
Lactated Ringer solution.
RATIONALE
Isotonic solutions are used to replace extracellular fluid volume without causing a shift of fluid
between compartments. They are osmotically equivalent to plasma, meaning they have a similar
concentration of solutes. This characteristic is vital for maintaining cellular integrity and
hemodynamic stability in clients experiencing fluid deficits.
Q4 QUESTION 4 OF 104
One of the first indications of fluid volume deficit is:
RESPONSE
Correct Answer:
tachycardia.
RATIONALE
Fluid volume deficit initially leads to compensatory mechanisms that maintain cardiac output.
Increased heart rate is an early sign as the body attempts to circulate the reduced blood volume
more rapidly. This physiological response aims to perfuse vital organs despite decreasing
intravascular fluid.
Q5 QUESTION 5 OF 104
The mucous membranes of a normally hydrated individual are:
RESPONSE
Correct Answer:
moist.
RATIONALE
Moist mucous membranes indicate adequate hydration and normal tissue perfusion. This
moistness is maintained by continuous secretion of mucus, which lubricates surfaces and traps
pathogens. Dry or sticky mucous membranes are early indicators of dehydration.

, Q6 QUESTION 6 OF 104
Of the following clients, the nurse recognizes that the individual who is most at risk for a
fluid volume deficit is:
RESPONSE
Correct Answer:
42-year-old with severe vomiting.
RATIONALE
The question asks to identify the client most at risk for fluid volume deficit. This requires
understanding the physiological factors that predispose individuals to dehydration. The rationale
should explain which demographic or clinical condition increases this risk, focusing on
mechanisms like increased insensible fluid loss, decreased intake, or impaired regulatory function.
Q7 QUESTION 7 OF 104
The single best indicator of fluid status is the nurse's assessment of the client's:
RESPONSE
Correct Answer:
daily body weight
RATIONALE
Accurate fluid status assessment relies on monitoring daily weight changes, as even minor
fluctuations can indicate significant fluid shifts. This metric provides a more sensitive and objective
measure of fluid balance than other indicators like skin turgor or mucous membranes. Therefore,
daily weight is the most reliable indicator of a client's fluid status.
Q8 QUESTION 8 OF 104
For the client who needs fluid replacement, which of the following should be avoided?
RESPONSE
Coffee
