A nurse administers an intravenous solution 3. Hypotonic
of 0.45% sodium chloride. With respect to Hypotonic solutions are less concentrated than body fluids (< than 0.85g of NaCl/100
human blood cells, this solution is: mL)
1. Isotonic
2. Isomeric
3. Hypotonic
4. Hypertonic
A client has been vomiting for 24 hours and 4. Orthostatic hypotension
is experiencing dizziness on arising. During
an assessment in the emergency
department, the client's skin is pale and
moist and the blood pressure is 108/70 when
the client is supine and 88/60 when the
client is standing. The nurse suspects this
client has:
1. Hyperkalemia
2. Hypoglycemia
3. Fluid overload
4. Orthostatic hypotension
Which assessment data should the nurse 3. Distended jugular veins
anticipate when admitting a client with an
extracellular fluid excess?
1. Elevated hematocrit
2. Rapid, thready pulse
3. Distended jugular veins
4. Increased serum sodium
The nurse is aware that the body's attempts 3. Specific gravity
to compensate for excessive fluid losses Specific gravity increased as urine becomes more concentrated but he body's attempt
associated with diarrhea are evident in an to conserve water.
increased:
1. Hematocrit
2. Temperature

2. The presence of dry skin
3. A decrease in blood pressure
4. An altered general appearance
Two body system that interact with the 3. Respiratory and urinary systems
bicarbonate buffer system to preserve the
normal body fluid pH of 7.4 are the:
1. Skeletal and nervous system
2. Circulatory and urinary system
3. Respiratory and urinary systems
4. Muscular and endocrine systems
Which statement correctly compares blood 1. Both contain the same kinds of ions
plasma and interstitial fluid? Blood plasma and interstitial fluid are both part of the extra cellar fluid and are of the
1. Both contain the same kinds of ions same ionic composition.
2. Plasma exerts lower osmotic pressure than
does interstitial fluid
3. Plasma contains slightly more of each kind
of ion than does interstitial fluid
4. The main cation in plasma is sodium,
whereas the main cation in interstitial fluid is
potassium
The weight of extracellular body fluid is 2. Interstitial fluid
approximately 20% of the total body weight ~ 16% of body weight
of an average individual. The component of
the extracellular fluid that contributes the
greatest portion to this amount is the:
1. Plasma fluid
2. Interstitial fluid
3. Fluid in dense tissue
4. Fluid in body secretions
The most important electrolyte of 4. Potassium
intracellular fluid is: The concentration of potassium is greater inside the cells and is important in
1. Sodium establishing a membrane potential, a critical factor in the cel's ability to function.
2. Calcium
