Module 7 IV access

Which of the following methods of medication administration will result in the fastest absorption rate?

• Intramuscular injection in the deltoid

• Subcutaneous injection in the abdomen

• Intravenous injection

• Intradermal injection in the forearm

Which patient would be appropriate for intravenous (IV) cannulation?

• A) A 68-year-old male with ischemic chest pain

• B) A 2-year-old female experiencing vomiting and diarrhea for 4 days

• C) A 25-year-old pregnant female, hypotensive after a motor vehicle collision at 32 weeks gestation

• D) All of the above

What does extravasation refer to?

• A) IV cannulation of more than one vein

• B) IV cannulation of an artery

• C) A patent IV line

• D) Infiltration of blood and IV fluid caused by multiple puncture sites in the vein wall

Solution has a higher solute concentration on one side of a semipermeable membrane than on the other side:

• Hypotonic

• Isotonic

• Hypertonic

• Colloid

Solutions on opposite sides of a semipermeable membrane are in equal concentration:

• Hypotonic

• Isotonic

• Hypertonic

• Colloid

What is important to check on an infusion pump prior to transporting a patient from a hospital to another facility?

• Hematoma and extravasation

• Foreign proteins in the IV tubing or solution, causing fever, chills, backache, headache, nausea, vomiting

• Proper rate, solution, concentration, clarity, and expiration

• Motion frequency increases the risk of mechanical phlebitis

If you suspect a clot has formed at the end of the catheter, why should you not try to dislodge it with a fluid bolus?

• Hematoma and extravasation

• Foreign proteins in the IV tubing or solution causing fever, chills, backache, headache, nausea, vomiting

• This may create an embolus, causing neurological or respiratory complications

• Lower the arm, apply a warm compress, and have the patient make a fist

Match the statement with the correct response regarding IV cannulation, direct pressure IV infusion devices, and IV infusion pumps.

• correct response for direct pressure IV infusion devices

• IV infusion pumps

• correct response for IV infusion pumps

• direct pressure IV infusion devices

• correct response for IV cannulation

• IV cannulation

If no blood was observed and you didn’t feel the catheter enter the vein, what should you do?

• Hematoma and extravasation

• Pull back the catheter without exiting the skin, reassess the vein position, and reattempt

• Motion frequency increases the risk of mechanical phlebitis

• Check the site for infiltration, pinched tubing, closed clamp, turned stopcock, or clogged filter

If a vein is difficult to palpate, what actions could you take?

• Hematoma and extravasation

• Motion frequency increases the risk of mechanical phlebitis

• Lower the arm, apply warm compresses, have the patient make a fist, and tap the vein

• This may create an embolus, causing neurological or respiratory complications
