NURS 402- Final Exam questions with correct
answers
Methods to promote vein distention Correct Answer-Scrub in the
direction of the venous flow, Gravity- hang arm off bed, Fist clenching,
Warm compress, Blood pressure cuff, Tourniquet- 3 to 4 inches above,
Transillumination
indications for 24-26 gauge IV Correct Answer-smallest, shortest- not
ideal for viscous infusions, expect blood transfusions to take longer,
preferred for infants and small children
approximate flow rate for 24-26 gauge IV Correct Answer-24 mL/min
indications for 22 gauge IV Correct Answer-adequate for most therapy-
blood can transfuse without damage
approximate flow rate for 22 gauge IV Correct Answer-38 mL/min
indications for 20 gauge IV Correct Answer-adequate for all therapies,
most providers prefer not to go smaller than this for surgery
approximate flow rate for 20 gauge IV Correct Answer-65 mL/min
indications for 18 gauge IV Correct Answer-preferred size for surgery,
veins needs to be large enough to accommodate the cath
,approximate flow rate for 18 gauge IV Correct Answer-110 mL/min
indications for 14-16 gauge IV Correct Answer-for trauma and surgical
patients requiring rapid transfusion, vein needs to be large enough to
accommodate the cath
approximate flow rate for 14-16 gauge IV Correct Answer-over 200
mL/min
site of IV insertion Correct Answer-appropriate veins for peripheral
catheter placement include the dorsal venous network- basilic, cephalic,
and median veins and their branches
IV in hands Correct Answer-not appropriate for older patients with a
loss of skin turgor and poor vein condition and for patients receiving
infusion therapy in an ambulatory care clinic or home care
contraindications for IV placement Correct Answer-mastectomy,
axillary lymph node dissection, lymphedema, paralysis of the upper
extremity, and presence of dialysis grafts/fistulas
midline catheter Correct Answer-typically inserted in the basilic vein of
the upper arm- allows greater hemodilution of the fluids and medications
being infused
, PICC line Correct Answer-basilic vein is the preferred site, sterile
insertion, chest X-ray to verify placement
PICC line indications Correct Answer-accommodates infusions of all
types- lengthy courses of antibiotics, chemotherapy, parenteral nutrition,
and vasopressors can benefit from this catheter; can be used for blood
sampling
non tunneled percutaneous central venous catheters Correct Answer-
emergent or trauma situations, critical care, and surgery
tunneled percutaneous central venous catheters Correct Answer-used
when the need for infusion therapy is frequency and long term;
parenteral nutrition for months, years, or the remainder of their lives
commonly choose this
implanted ports Correct Answer-patients who are expected to require IV
therapy for more than a year, may be access for contrast enhanced CT
hemodialysis catheters Correct Answer-used for hemodialysis procedure
or a pheresis procedure that harvests specific blood cells- very large
lumen
local IV complication S/S Correct Answer-redness, pus, warmth,
induration, pain
