10 Questions
What happens when there is an elevation of solutes like urea, unlike an elevation in plasma sodium concentration?
It does not cause cellular dehydration and does not activate mechanisms to defend body fluid homeostasis.
Which of the following solutes are considered effective solutes?
Sodium (Na+) and mannitol
What happens when glucose is administered under conditions of impaired cellular uptake, such as insulin deficiency?
Glucose acts as an effective extracellular solute.
Which of the following statements about osmolality is correct?
Osmolality is the concentration of all solutes, both permeable and impermeable, in a given weight of water.
What happens when hypotonic fluid is administered intravenously?
It causes cellular hydration and a decrease in extracellular fluid volume.
Which of the following conditions is associated with an increase in extracellular fluid volume?
Edema
What is the primary reason for administering isotonic saline intravenously?
To maintain extracellular fluid volume
Which of the following conditions is characterized by a decrease in serum sodium concentration?
Hyponatremia
What is the primary mechanism by which the body defends against changes in osmolality?
Regulation of water intake and excretion
Which of the following solutes is considered unique in terms of its osmotic behavior?
Glucose
