[APUS57]

When a nurse administers a hypotonic intravenous solution to a client, how will the water move?
 
  1. By osmosis from the plasma compartment to the interstitial compartment.
  2. By diffusion from the plasma compartment to the interstitial compartment.
  3. By diffusion from the interstitial compartment to the plasma compartment.
  4. By osmosis from the interstitial compartment to the plasma compartment.

Question 2

The nurse is reviewing a client's lab values, which indicate normal serum osmolality. Which intravenous solutions will not cause a fluid shift in this client?
 
  1. Colloids
  2. Isotonic solutions
  3. Hypertonic solutions
  4. Hypotonic solutions

Answer to Question 1

Correct Answer: 1
Rationale 1: Water will move from the plasma compartment to the interstitial compartment, by osmosis, in response to administration of hypotonic intravenous solutions.
Rationale 2: Water does not move by diffusion.
Rationale 3: Water does not move by diffusion.
Rationale 4: Water will move from the plasma compartment to the interstitial compartment, by osmosis, in response to administration of hypotonic intravenous solutions.
Global Rationale: Water will move from the plasma compartment to the interstitial compartment, by osmosis, in response to administration of hypotonic intravenous solutions. Water does not move by diffusion.

Answer to Question 2

Correct Answer: 2
Rationale 1: Colloids will likely cause a shift of fluid from the interstitial and/or intracellular space to the intravascular space.
Rationale 2: Isotonic solutions will likely cause no fluid shift in this client.
Rationale 3: Hypertonic solutions will likely cause a shift of fluid from the interstitial and/or intracellular space to the intravascular space.
Rationale 4: Hypotonic solutions will likely cause a shift of fluid from the intravascular space to the interstitial and/or intracellular space.
Global Rationale: Isotonic solutions will likely cause no fluid shift in this client. Colloids will likely cause a shift of fluid from the interstitial and/or intracellular space to the intravascular space. Hypertonic solutions will likely cause a shift of fluid from the interstitial and/or intracellular space to the intravascular space.
