NUR 172 EXAM 2 HONDROS
QUESTIONS & DETAILED ANSWERS
RATED 100% CORRECT
isotonic solution - correct answer ✔✔A solution in which the concentration of solutes is
essentially equal to that of the cell which resides in the solution
patient admitted with transmission-based precautions what is the minimum PPI needed to be
worn in this room? - correct answer ✔✔Gloves and Gown
hypertonic solution - correct answer ✔✔A solution in which the concentration of solutes is
greater than that of the cell that resides in the solution
hypotonic solution - correct answer ✔✔A solution in which the concentration of solutes is less
than that of the cell that resides in the solution
Heparin antidote - correct answer ✔✔protamine sulfate
INR - correct answer ✔✔International Normalized Ratio - a calculation based on the PT used to
monitor patients using blood thinners. 2.0-3.0 is the range for people taking warfarin: Coumadin
Causes of hematoma - correct answer ✔✔poor venipuncture technique, flow clamp left open,
tourniquet left on to long, cannula to large, digging into vein
Signs of hematoma - correct answer ✔✔Ecchymosis, immediate swelling at the site &
discomfort, leakage of blood at the insertion site- unable to advance cannula
, Phlebitis - correct answer ✔✔inflammation of the inner lining of a vein
thrombophlebitis - correct answer ✔✔inflammation of a vein associated with a clot formation
bacterial phlebitis is caused by - correct answer ✔✔Poor hand hygiene, lack of aseptic
technique, failure to check equipment, or recognize early signs of phlebitis
Often occurs during insertion
Phlebitis Scale - correct answer ✔✔0 = No symptoms
1 = Erythema at access site with or without pain
2 = Pain at access site with erythema and/or edema
3 = Pain at access site with erythema and/or edema, streak formation, palpable venous cord
4 = Pain at access site with erythema and/or edema, streak formation, palpable venous cord >1
inch in length, and purulent drainage
erythema - correct answer ✔✔redness of the skin
Infiltration - correct answer ✔✔admission of a non-vesicant med or solution into the
surrounding tissue
Extravasation - correct answer ✔✔admission of a vesicant into surrounding tissue
CVAD - correct answer ✔✔central vascular access device or indwelling line
treatment of thrombophlebitis - correct answer ✔✔complete bed rest
avoid massage
heat and elevation promote venous return
