Which hormones will the body use when there is too much fluid (fluid overload) or too
little fluid (dehydration)? Select all that apply. - correct answerAtrial natriuretic peptide
Antidiuretic hormone
Aldosterone
Match the description with the type of fluid imbalance. - correct answerHypervolemia -
Too much fluid accumulates and/or organs in the body are unable to manage or
excrete.
Hypovolemia - Blood is lost due to hemorrhage and poor fluid intake.
Maldistribution of fluid - Movement of fluid from one compartment to another without a
loss of fluid.
After being out at the beach for hours, an adult suffered from an extensive sunburn
covering their back, arms, and legs. Which fluid imbalance is this person most likely
experiencing? - correct answerHypovolemic fluid imbalance
Identify the signs and symptoms most likely seen with each type of fluid imbalance.
Each sign or symptom may be seen in more than one type of fluid imbalance. - correct
answer*Hypovolemia:*
Dizziness
Low blood pressure
Oliguria
*Maldistribution:*
Generalized swelling
*Hypervolemia:*
,Weight gain
Generalized swelling
Oliguria
You suspect someone may have hypervolemia. Which tests would most accurately
support this? - correct answerDaily weight
Read the case scenario below, and then select all the signs or symptoms that are
consistent with a fluid imbalance.
Chris (preferred pronouns: he, him) is a high school football player who came into the
office after practice. He said that he was dizzy and lightheaded. The nurse in the office
took his blood pressure and it was low. His pulse rate was elevated. He also had
bruising on both arms. The outside temperature during practice was 105 degrees
Fahrenheit, and Chris forgot to bring water. He has no medical history, but his father
has a history of heart disease and kidney disease. - correct answerDizzy and
lightheaded
Blood pressure and it was low
Pulse rate was elevated

Which of the following types of fluid imbalance could this student be experiencing? -
correct answerHypovolemia due to dehydration
Chris (preferred pronouns: he, him) is a high school football player who came into the
office after practice. He said that he was dizzy and lightheaded. The nurse in the office
took his blood pressure and it was low. His pulse rate was elevated. He also had

has a history of heart disease and kidney disease.
The intravascular system is depleted through __________ metabolism and fluid
__________ from sweat. This activates baroreceptors, which cause __________ in
order to __________ blood pressure. When fluid levels get __________ enough, blood
pressure starts to __________ and pulse rate starts to __________. The brain

Which strategies could have prevented this student's problems? Select all that apply. -
correct answerHaving water available at the practice
Taking frequent rest breaks
Offer shaded areas at practice
Select the mechanism that best explains the corresponding example. - correct
answerElectrolytes - Intravenous fluids used by healthcare professionals rely on sodium
concentrations to treat conditions of fluid imbalance.
Blood pressure - Receptors throughout the body that send signals to the autonomic
nervous system to constrict or dilate blood vessels depending on the fluid imbalance it
may sense.
Proteins - Low levels can cause movement of fluid into interstitial areas, causing
edema. For example, low levels can cause a water leak from the vascular area into the
surrounding tissue, causing edema.
Hormones - Renin is converted to angiotensinogen to cause vasoconstriction. It also
stimulates production of aldosterone by the adrenal gland, which helps to keep fluid in
the vascular system.
Categorize the following conditions with which type of fluid imbalance. - correct
answer*Hypovolemia:*
• Blood loss from external injury
• Dehydration
• Extensive burns
*Maldistribution:*
• Anaphylactic reaction
• Systemic inflammatory response syndrome
• Transfusion reaction
*Hypervolemia:*
• Heart failure
• Liver failure
, • Renal failure
Which environmental factors directly affect fluid balance? Select all that apply. - correct
answerLack of potable water in a small town.
Concentration of bisphenol A in food containers.
Regular daily temperature is 120 degrees Fahrenheit.
Which risk factors make older adults and children more sensitive to fluid imbalances?
Select all that apply. - correct answerWeight and height
Total body water differences
Kidney function
When the osmoreceptors detect a decreased blood volume and increased blood
concentration of salt, what function increases in the body? - correct answerThirst
Other than measuring fluid intake and output, how can fluid changes be accurately
measured in the body? Select all that apply. - correct answerWeight
Urinary frequency
What clues (symptoms) would alert you that you are dehydrated? - correct answer1. No
tears
2. Cracked tongue
3. Dry skin
4. Dry lips
5. Dry mucosa
6. Flaky scalp
Match each type of dehydration to the proper cell. - correct answer1. Hypertonic
2. Isotonic
3. Hypotonic
Match the type of dehydration with the correct definition. - correct answerThe
interpretation of the client's lab work indicated they lost fluid and electrolytes equally. -
Isotonic
The interpretation of the client's lab work indicated they lost more electrolytes than fluid.
- Hypotonic
The interpretation of the client's lab work indicated they lost more fluid than electrolytes.
- Hypertonic
What are some common reasons for dehydration? Select all that apply. - correct
answerBleeding from trauma
Diarrhea
Decreased fluid intake
Medications (diuretics)
