MULTIPLE CHOICE

 

1. The nurse is caring for a patient receiving antineoplastic medications intravenously. The nurse discovers that the intravenous site is red, edematous, and painful. The nurse knows that antineoplastic medications are vesicant medications and documents that the patient has experienced which of the following events?

a.	Occlusion
b.	Extravasation
c.	Phlebitis
d.	Thrombophlebitis

 

 

ANS:  B

When a vesicant medication infiltrates the tissue, this is called an extravasation. Occlusion refers to a thrombus or fibrin sheath that impedes the flow of IV fluids. Phlebitis occurs with redness surrounding the vein, and extravasation leads to trauma within the vein

2. Established standards for routine replacement of peripheral IV catheters and intravenous administration sets have recommended a maximum of _____ hours to reduce IV fluid contamination and prevent catheter site complications.

a.	24
b.	48
c.	72
d.	96

 

 

ANS:  D

Established standards for routine replacement of peripheral IV catheters and intravenous administration sets have recommended a maximum of 96 hours to reduce IV fluid contamination and prevent catheter site complications.

3. While assessing the patient, the nurse recognizes that special caution should be taken with the IV infusion because of fluid volume excess when the nurse notes the presence of which condition?

a.	Poor skin turgor
b.	Crackles in the lungs
c.	Decreased blood pressure
d.	Dry skin and mucous membranes

 

 

ANS:  B

Auscultation of crackles or rhonchi in the lungs may signal fluid buildup in the lungs caused by fluid volume excess. Poor skin turgor is common with fluid volume deficit. The pinched skin stays elevated for several seconds (tenting). This may be an indication of the need for IV therapy. Decreased blood pressure may indicate fluid volume deficit caused by a decrease in stroke volume. This may indicate the need for IV therapy. Dry skin and mucous membranes may indicate dehydration.

4. The nurse needs to specifically prevent air emboli that may result from IV therapy. What should the nurse make sure to do to prevent air emboli?

a.	Use a needleless system.
b.	Prime the tubing completely.
c.	Check for medication compatibility.
d.	Select a larger-gauge needle or catheter.

 

 

ANS:  B

Prime the infusion tubing by filling it with IV solution. Be certain that the tubing is clear of air and air bubbles. Large air bubbles can act as emboli. A needleless system does not specifically prevent the introduction of air emboli. Medication incompatibility may lead to crystallization of the medication and may cause emboli to form from precipitate. It will not lead, however, to air embolism. Catheter size does not contribute to emboli formation.

5. Which of the following steps is necessary when a patient is prepared for IV insertion?

a.	Shaving the hair from the site
b.	Selecting a proximal site in an extremity
c.	Applying a tourniquet 4 to 6 inches above the selected site
d.	Vigorously taping and massaging the selected vein

 

 

ANS:  C

Apply a flat tourniquet around the arm, above the antecubital fossa or 4 to 6 inches (10 to 15 cm) above the proposed insertion site. Do not shave the area. Shaving may cause microabrasions and may predispose to infection. Use the most distal site in the nondominant arm, if possible. Vigorous friction and multiple taping of the veins, especially in older adults, may cause hematoma and/or venous constriction.
