A nurse is caring for a client with an intravenous catheter. When administering medication by IV push through the port, the nurse pinches the tubing upstream from the port when instilling the medication.
 
  Which of the following reasons explains the nurse's action? A) Provides access to the inside of the tubing
  B) Creates negative pressure in the syringe
  C) Validates that the IV catheter is in the vein
  D) Ensures that the medication reaches the client

Question 2

A client with protracted nausea and vomiting has been receiving intravenous solution at 125 ml/h for the past several hours.
 
  The administration of this solution has resulted in an increase in blood pressure because the water in the solution has passed through the semipermeable membrane of blood cells, causing them to swell. This client has been receiving: A) Packed red blood cells
  B) An isotonic solution
  C) A hypertonic solution
  D) A hypotonic solution

Answer to Question 1

D
Feedback:
Pinching the tubing when instilling it with the drug ensures that the tube does not get backfilled and that the drug gets administered to the client. Piercing the port with the needle provides access to the inside of the tubing. Negative pressure is created by pulling back the plunger of the syringe. Pinching the tubing when instilling it with the drug does not validate that the IV catheter is in the vein, but the presence of blood in the tubing does.

Answer to Question 2

D
Feedback:
Because hypotonic solutions are dilute, the water in the solution passes through the semipermeable membrane of blood cells, causing them to swell. This temporarily increases blood pressure as it expands the circulating volume. Hypertonic solutions draw water out of body cells while isotonic solutions have little effect on the distribution of body fluids. Blood transfusions do not cause the entry of water into body cells.
