Caring for CVAD: Lesson 1-2-3-4 Post-Test
Questions and Verified Answers
POST-TEST 1:
Choose the characteristics of a tunneled central vascular access device.
(Select all that apply.)
A. Inserted directly into a large vein
B. Inserted through a large vein in the antecubital fossa and threaded into the tip of
the superior vena cava
C. Inserted through subcutaneous tissue between the clavicle and nipple, then into a large vein, and
threaded into the superior vena cava
D. Catheter tip lies in the larger vessels of the upper arm
E. Lower risk of infection than a nontunneled CVAD
F. Catheter tip lies in the superior vena cava
G. Held in place with a Dacron cuff
H. May be single, double, or triple lumen

I. Inserted surgically with the patient in the operating room
J. May be inserted by a specially trained nurse Ans: C-E-F-G-H-I
C. Inserted through subcutaneous tissue between the clavicle and nipple, then into a large vein, and
threaded into the superior vena cava.
E. Lower risk of infection than a nontunneled CVAD

H. May be single, double, or triple lumen
I. Inserted surgically with the patient in the operating room
*A tunneled central vascular access device is inserted by a health care provider with the patient in the
operating room under local anesthesia. It is inserted through the subcutaneous tissue and then into a
large vein and threaded into the superior vena cava. It is held in place by a Dacron cuff under the skin
of the chest wall. Because the subcutaneous tunnel creates space between the end of the catheter and
the actual vein, the risk of infection is lower. The catheter tip lies in the superior vena cava. These
catheters have single, double, or triple lumens that allow simultaneous administration of several
infusions. A percutaneous central venous catheter is inserted directly into a large vein. A peripherally
inserted centra catheter (PICC) line is inserted through a large vein in the antecubital fossa and
threaded into the tip of the superior vena cava. A PICC line may be inserted by a specially trained
nurse. The catheter tip of a midline catheter (MLC) lies in the larger vessels of the upper arm.
