Question 1

1 / 1 pts

A patient has been receiving intravenous (IV) antibiotics and as a result has had several IV site locations. What action can the nurse take to promote venous distention in the patient? (Select all that apply.)

Correct!

Apply a warm pack to the arm for several minutes.

Rub or stroke the patient's arm.

To promote venous distention in the patient, the nurse may place the patient's arm in a dependent position (avoid elevating the arm), and rub or stoke the patient's arm. The nurse may also apply a warm pack to the arm for several minutes or apply one tourniquet on the mid-upper arm and stroke downward toward the hand. After 1 to 2 minutes, apply a second tourniquet slightly below the antecubital fossa. Heat causes vasodilation, and application of the tourniquets forces blood to distend the smaller veins. Although relaxation techniques may prevent vasoconstriction, they fail to promote venous distention. Sites distal to a previous venipuncture site and an extremity with compromised circulation such as paralysis should be avoided, because such sites increase the risk of infiltration of a newly placed IV line and excessive vessel damage. Gentle rubbing or stroking of the patient's arm promotes venous distention. Vigorous rubbing and multiple tapping of the patient's veins should be avoided. These techniques may cause injury to the vein, such as a hematoma, or cause venous constriction.

Intravenous Therapy: Lesson 2 Post-Test: BSN246-07 Concepts of Nursing I 2021-2

At what angle should an IV catheter puncture the skin and vein during insertion in a middle-aged adult?

Correct!

10- to 30-degree angle.

The skin and vein should be punctured with the catheter held at a 10- to 30-degree angle. The angle of insertion may be decreased when inserting the catheter into an elderly patient to avoid rolling the vein or puncturing through the vein. Superficial veins require a smaller angle, and deeper veins require a greater angle. A 45-degree angle may be used for administering a subcutaneous injection. A 90-degree angle may be used to administer an intramuscular injection.

Question 3

1 / 1 pts

When should the tourniquet be released a second time during the procedure for insertion of a peripheral intravenous device?

After a "flashback" of blood is observed and the catheter has been advanced off the stylet.

The tourniquet is released after a "flashback" of blood is observed in the catheter's flashback chamber and the catheter has been advanced off the stylet until the catheter hub rests at the venipuncture site. Releasing the tourniquet restores blood flow to the arm. If the tourniquet is released too soon, the vein will collapse, making insertion more difficult.

Question 4

1 / 1 pts

The nurse is preparing an IV infusion before initiating an IV. Which of the following is a correct action performed by the nurse?

Correct! After spiking the bag of IV fluids, the nurse fills the drip chamber 1/3 to 1/2 full and primes the tubing, making sure there are no bubbles.

The correct procedure for preparing an IV infusion before initiating an IV is as follows: The nurse opens the infusion set and places the roller clamp 2 to 5 cm (3/4 to 2 inches) below the drip chamber and moves the roller clamp to the off position. The nurse removes the protective sheath over the IV tubing port on plastic IV solution bag. The nurse removes the sheath from the insertion spike and inserts the spike into the IV bag, fills the drip chamber 1/3 to 1/2 full, and primes the infusion tubing with IV solution, making sure there are no air bubbles.

Question 5

1 / 1 pts

The nurse is preparing an IV infusion before initiating an IV. The nurse removes the protective sheath covering the tubing insertion spike and accidentally touches the spike. What is the nurse’s best action at this time? https://nightingale.instructure.com/courses/3265985/quizzes/7825497

Discard IV tubing and obtain a new one.

The insertion spike has been contaminated. To reduce the likelihood of infection, the nurse should discard the tubing and obtain a new one.

Question 6

1 / 1 pts

The nurse is assessing the patient for signs and symptoms of fluid volume excess. Which of the following would indicate the patient is experiencing this complication and should be reported? (Select all that apply.)

Shortness of breath and crackles in lungs. Elevated blood pressure and edema.

Signs and symptoms of fluid volume excess (FVE) include crackles in lungs, shortness of breath, elevated blood pressure, and edema. Signs and symptoms of fluid volume deficit include decreased urine output, dry mucous membranes, hypotension, and tachycardia. Good skin turgor and capillary refill less than 3 seconds are normal findings.
