Q

What would the nurse check with a patient that has a fluid volume deficit? Why?

A

neurological function
–> LOC, PEERRLA, voluntary movements of extremities, muscle strength, reflexes
WHY?
–> Causes an imbalance in the body and doesn’t provide the brain with the water and electrolytes that are needed

Q

When monitoring a client with prolonged vomiting for fluid volume deficit, what does the nurse recognize about fluid shifts that occur as a result on vomiting?
A: Fluid moves from the cells into the interstitial space and the blood vessels
B: Fluid moves from the vascular system causing cellular swelling and rupture
C: An overload of extracellular fluid occurs with a significant increase in intracellular fluid volume
D. Excretion of large amounts of interstitial fluid occurs with depletion of extracellular fluids
