Question 1 NSG 3850 Exam 1
2/3 of body fluid is intracellular. 1/3 is extracellular. T/F?
CORRECT ANSWER
True
Rationale: The statement is true because the majority of the body's fluid is indeed intracellular, existing
within cells, while a smaller proportion, approximately 1/3, is extracellular, existing outside of cells in spaces
such as blood plasma and interstitial fluid. This distribution allows cells to maintain their internal environment
and regulate the balance of fluids and electrolytes necessary for proper cellular function.
Question 2 NSG 3850 Exam 1
Where is the extracellular fluid?
CORRECT ANSWER
- between cells (interstitial)
- blood vessels (vascular)
- dense connective tissue and bone
- CSF, GI fluids, synovial (transcellular)
Rationale: Extracellular fluid refers to the fluid outside cells, which can be found in various compartments
such as the spaces between cells (interstitial), within blood vessels (vascular), and in specialized fluid-filled
compartments like CSF, GI fluids, and synovial fluid. These locations are distinct from the intracellular fluid,
which is confined within cells, and the correct grouping of extracellular fluid locations highlights the unique
characteristics and functions of each compartment.
Question 3 NSG 3850 Exam 1
When ADH is low, urine volume is
CORRECT ANSWER
high
Rationale: When ADH (antidiuretic hormone) is low, it means the kidneys are not receiving the signal to
reabsorb water back into the bloodstream, so more water is excreted in the urine. As a result, the kidneys
produce dilute urine, leading to a higher urine volume.
,Question 4 NSG 3850 Exam 1
When aldosterone is high, urine volume is
CORRECT ANSWER
low
Rationale: Aldosterone is a hormone that regulates electrolyte balance and fluid retention in the body,
causing the kidneys to retain sodium and water. When aldosterone levels are high, the kidneys retain more
water, leading to a decrease in urine volume.
Question 5 NSG 3850 Exam 1
ADH is the "____ water" hormone.
CORRECT ANSWER
free *causes kidneys to reabsorb plain water
Rationale: ADH (Antidiuretic Hormone) triggers the kidneys to reabsorb water back into the bloodstream,
which is a crucial function in regulating the body's water balance. This process is essential for concentrating
the urine and preventing excessive water loss, making ADH a hormone that promotes water conservation, thus
it's called the "water" hormone.
Question 6 NSG 3850 Exam 1
Aldosterone is the "____ water" hormone.
CORRECT ANSWER
salt *causes kidneys to reabsorb water AND sodium
Rationale: Aldosterone, often referred to as the "water-retaining" hormone, plays a crucial role in regulating
the balance of fluids in the body by stimulating the kidneys to reabsorb water, which in turn, helps to conserve
sodium. This relationship between aldosterone, water reabsorption, and sodium retention is essential for
maintaining proper blood pressure and preventing dehydration.
, Question 7 NSG 3850 Exam 1
BNP is synthesized and released from ventricular cells when ventricular diastolic pressure
INCREASES abnormally, as in:
CORRECT ANSWER
heart failure.
Rationale: BNP is a hormone that helps regulate the balance of fluids in the body, and its release is triggered
by increased ventricular diastolic pressure, which occurs when the heart is unable to relax and fill properly due
to excessive fluid buildup or increased stiffness of the heart muscle. The increased pressure stretches the
ventricular cells, leading to the release of BNP, which then signals the kidneys to remove excess fluid from the
body and reduce the workload on the heart.
Question 8 NSG 3850 Exam 1
Natriuretic peptides (NPs) promote fluid _______________ in _________.
CORRECT ANSWER
excretion, urine
Rationale: Natriuretic peptides (NPs) promote fluid excretion in the kidneys by causing an increase in sodium
excretion, leading to a decrease in fluid retention in the body. This process ultimately results in the formation
and production of urine, which carries excess fluid and electrolytes out of the body.
Question 9 NSG 3850 Exam 1
Reabsorption of Na+ and H2O caused by aldosterone makes a smaller volume of urine and
___________ extracellular fluid volume.
CORRECT ANSWER
expands
Rationale: Aldosterone stimulates the reabsorption of sodium ions (Na+) and water (H2O) by the kidneys,
which leads to an increase in blood volume due to the reabsorbed water contributing to the overall blood
volume. As a result, the increased blood volume causes the body to retain more water, leading to an expansion
of extracellular fluid volume, not a decrease.
