Question 1 NR 324 Exam 1
What age group has the highest percentage of water content?
CORRECT ANSWER
Preterm / Neonates
Rationale: The body's water content decreases with age due to the increase in body fat and dry weight of organs, resulting in preterm/neonates
having the highest percentage of water content due to their high proportion of water-rich tissues. This is because neonates have a relatively low
body fat percentage and their organs are largely composed of water, making them the age group with the highest water content percentage.
Question 2 NR 324 Exam 1
Two fluid compartments in the body
CORRECT ANSWER
Intracellular space (inside cells) located in the ICF
Extracellular space (outside cells) located in the ECF
Rationale: The body's fluid compartments are defined based on their location relative to cells, with intracellular fluid (ICF) being the fluid found
inside cells and extracellular fluid (ECF) being the fluid found outside cells. This classification system is based on the physical boundaries that
separate these fluid compartments, with cell membranes serving as the dividing line between the ICF and ECF.
Question 3 NR 324 Exam 1
ICF makes up what percent of total body weight?
CORRECT ANSWER
40%
Rationale: ICF, or Intracellular Fluid, is a component of body water that makes up approximately 2/3 of an adult's total body weight, while the
remaining 1/3 is made up of blood plasma, which is essentially the Extracellular Fluid (ECF). Since the total body weight is comprised of these two
components, the percentage of ECF is calculated as 1/3, or approximately 33.3%, and subtracting ECF from 100% gives the percentage of ICF.
Question 4 NR 324 Exam 1
What are the two main compartments containing ECF? What other compartments are there?
CORRECT ANSWER
Interstitial fluid (fluid in the spaces between cells)
Intravascular fluid (plasma)
Other compartments include lymph and transcellular fluids
Rationale: The two main compartments containing extracellular fluid (ECF) are interstitial fluid and intravascular fluid because these two
compartments are directly connected to the bloodstream and surround cells, making them the primary locations of ECF. The other compartments,
such as lymph and transcellular fluids, are connected to these main compartments through various mechanisms and serve specific functions
within the body, making them relevant but secondary categories.
,Question 5 NR 324 Exam 1
Transcellular fluid includes
CORRECT ANSWER
Cerebrospinal fluid, fluid in the gastrointestinal tract, and joint spaces as well as pleural, peritoneal, intraocular, and pericardial fluid.
Rationale: Transcellular fluid is a type of body fluid that originates from or is closely associated with specific organs or systems, and its
composition and volume are regulated independently of the main circulatory system. The listed fluid types are examples of transcellular fluid
because they are produced by or in association with specific organs, such as the brain (cerebrospinal fluid), gastrointestinal tract (gastrointestinal
fluid), and eyes (intraocular fluid), and are not primarily regulated by the circulatory system.
Question 6 NR 324 Exam 1
1L of water = _____ lb.
CORRECT ANSWER
2.2 lb (1kg)
Rationale: The conversion from liters to pounds is based on the density of water, which is approximately 1 kilogram per liter (kg/L), and knowing
that 1 kilogram is equivalent to 2.20462 pounds, allowing the calculation to be performed. By multiplying the density of water by the unit volume
(1 liter), and then converting kilograms to pounds, the correct weight in pounds for 1 liter of water can be accurately determined.
Question 7 NR 324 Exam 1
The concentrations of electrolytes in body fluids is expressed in _________
CORRECT ANSWER
milliequivalents (mEq) per Liter
Rationale: The correct unit of concentration for electrolytes in body fluids is milliequivalents per Liter because it takes into account the chemical
reactivity of each electrolyte, allowing for accurate measurement of their effects on the body's electrical activity, such as heart rhythm and muscle
contractions. This is in contrast to units like milligrams per Liter, which only measure the mass of the electrolyte without considering its chemical
properties.
Question 8 NR 324 Exam 1
What are the main Ions found in the ECF and ICF
CORRECT ANSWER
ECF cation- sodium, with small amounts of potassium, calcium, and magnesium
ECF anion- chloride, with small amounts of bicarbonate, sulfate, and phosphate anions.
ICF cation- potassium, with small amounts of magnesium and sodium
ICF anion- phosphate, with some protein and a small amount of bicarbonate.
Rationale: The main ions in ECF (extracellular fluid) and ICF (intracellular fluid) are primarily determined by the selective permeability of the cell
membrane, which allows certain ions to pass through more easily than others. This selective permeability, along with the active transport
mechanisms in place, results in a concentration gradient of ions across the cell membrane, which ultimately determines the composition of ECF
and ICF.
, Question 9 NR 324 Exam 1
Hypovolemia (ECF volume deficit)
CORRECT ANSWER
abnormal loss of normal body fluids, (D/V, hemorrhage, polyuria) inadequate intake, or plasma-to-interstitial fluid shift
Rationale: Hypovolemia, or ECF (extracellular fluid) volume deficit, occurs when there's a loss of normal body fluids or an inadequate intake,
resulting in a decrease in the volume of circulating blood, which can be caused by dehydration, hemorrhage, or excessive urine production. The
plasma-to-interstitial fluid shift also contributes to hypovolemia, as fluid shifts from the bloodstream to the surrounding tissues, reducing the
volume of circulating blood and worsening the condition.
Question 10 NR 324 Exam 1
Fluid volume deficit
Assessment- Causes-Treatment-Client education
CORRECT ANSWER
Assessment- Restlessness, drowsiness, lethargy, confusion
• Thirst, dry mucous membranes
• Cold clammy skin
• Decreased skin turgor, ↓ capillary refill
• Postural hypotension, ↑ pulse, ↓ CVP
• ↓ Urine output, concentrated urine
• ↑ Respiratory rate
• Weakness, dizziness
• Weight loss
• Seizures, coma
Causes- • ↑ Insensible water loss or perspiration (high fever, heatstroke)
• Diabetes insipidus
• Osmotic diuresis
• Hemorrhage
• GI losses: vomiting, NG suction, diarrhea, fistula drainage
• Overuse of diuretics
• Inadequate fluid intake
• Third-space fluid shifts: burns, pancreatitis
Treatment- replace water and electrolytes with balanced IV solutions
Client education- Good skin care, if orthostatic hypotension is present, teach to change positions slowly, remind patient to drink
Rationale: This answer is correct because it accurately identifies the assessment, causes, and treatment of fluid volume deficit, a condition
caused by an excessive loss of body fluids, often resulting in dehydration. The client education section provides essential information for
preventing and managing fluid volume deficit, making it a comprehensive and well-rounded answer.
Question 11 NR 324 Exam 1
Hypervolemia (ECF volume excess)
CORRECT ANSWER
Excessive intake of fluids, abnormal retention of fluids (HF or renal failure), or interstitial-to-plasma fluid shift
Rationale: Hypervolemia occurs when there is an excessive amount of fluid in the extracellular fluid (ECF) compartment, which can result from
excessive intake of fluids, abnormal retention of fluids due to conditions like heart failure (HF) or renal failure, or interstitial-to-plasma fluid shift,
where fluid moves from the blood vessels to the interstitial spaces. These conditions lead to an increased ECF volume, causing hypervolemia,
which can have various health consequences if left untreated.

Excessive intake of fluids, abnormal retention of fluids (HF or renal failure), or interstitial-to-plasma fluid shift
