    Exercise \(\PageIndex{1}\)

    A nurse is preparing to teach a client about temperature regulation and homeostasis. Which statement should the nurse include in the teaching plan?

  • Homeostasis makes your blood pressure rise when you experience stress.
  • Homeostasis allows you to maintain a stable body temperature despite the outside temperature.
  • Homeostasis is solely under the control of your brain and nervous system.
  • Homeostasis converts food into energy.
    • Answer

    Homeostasis allows you to maintain a stable body temperature despite the outside temperature.

    Exercise \(\PageIndex{2}\)

    The nurse is caring for a client with a high serum osmolality. Which condition is the client likely to have?

  • Dehydration
  • Fluid volume excess
  • Hypothermia
  • Hyperkalemia
    • Answer

    Dehydration

    Exercise \(\PageIndex{3}\)

    The nurse is caring for a client with excessive fluid accumulation in the pleural cavity. The nurse determines that fluid is accumulating in which fluid compartment?

  • Intracellular
  • Extracellular
  • Interstitial
  • Transcellular
    • Answer

    Transcellular

    Exercise \(\PageIndex{4}\)

    The nurse is caring for a client who has been experiencing diarrhea. Which anion does the nurse anticipate the client is losing through this loss of extracellular fluid?

  • Calcium
  • Sodium
  • Potassium
  • Chloride
    • Answer

    Chloride

    Exercise \(\PageIndex{5}\)

    The nurse is caring for a client with a gastrointestinal hemorrhage. Which fluid compartment does the nurse understand is losing fluid?

  • Interstitial compartment
  • Intravascular compartment
  • Transcellular compartment
  • Intracellular compartment
    • Answer

    Intravascular compartment

    Exercise \(\PageIndex{6}\)

    A nurse is caring for a pregnant client who is in labor. Which of the following statements accurately describes the concept of positive feedback in the context of labor?

  • Oxytocin is suppressed, stimulating uterine contractions.
  • Oxytocin is released, stimulating uterine contractions.
  • Oxytocin is suppressed, increasing contractions.
  • Oxytocin is released, halting uterine contractions.
    • Answer

    Oxytocin is released, stimulating uterine contractions.

    Exercise \(\PageIndex{7}\)

    A nurse is teaching a group of nursing students about the Na+K+ATPase pump. Which of the following statements accurately describes the role of this pump in maintaining cellular function?

  • Potassium moves out of the cell and sodium moves into the cell, thereby maintaining a higher concentration of potassium inside the cell.
  • Sodium moves out of the cell and potassium moves into the cell, thereby maintaining a higher concentration of sodium inside the cell.
  • Sodium and potassium move out of the cell, thereby maintaining an equal concentration of electrolytes inside and outside the cell.
  • Sodium and potassium move into the cell, thereby maintaining a higher concentration of electrolytes outside the cell.
    • Answer

    Sodium moves out of the cell and potassium moves into the cell, thereby maintaining a higher concentration of sodium inside the cell.

    Exercise \(\PageIndex{8}\)

    Which of the following is an example of a negative feedback loop in the human body?

  • Release of oxytocin during childbirth
  • Blood clotting
  • Lactation
  • Regulation of blood glucose levels
    • Answer

    Regulation of blood glucose levels

    Exercise \(\PageIndex{9}\)

    The nurse is caring for a client with a fluid imbalance. Which statement accurately describes the distribution of intracellular (ICF) and extracellular fluid (ECF) in the body?

  • The ICF constitutes approximately 40% of total body fluid, and ECF accounts for 20%.
  • The ICF constitutes approximately 40% of total body fluid, and ECF accounts for 60%.
  • The ICF constitutes approximately 20% of total body fluid, and ECF accounts for 80%.
  • The ICF constitutes approximately 80% of total body fluid, and ECF accounts for 20%.
    • Answer

    The ICF constitutes approximately 40% of total body fluid, and ECF accounts for 20%.

    Exercise \(\PageIndex{10}\)

    Which of the following best describes the concept of osmotic equilibrium in the body?

  • The balance of water and electrolytes in the body
  • The balance of water and solutes across a semipermeable membrane
  • The balance of ions in the body’s extracellular and intracellular fluid compartments
  • The balance of acids and bases in the body’s fluid
    • Answer

    The balance of water and solutes across a semipermeable membrane
