21
Q

air embolism:

A

air enters the central veins

22
Q

air embolism: causes

A

solutions runs dry, air in tubing, loose connections, improper removal of CVAD, poor technique with dressing or tubing changes

23
Q

air embolism: S&S

A

dyspnea, tachypnea, lightheadedness, palpitations, drop in BP, weakness, cyanosis, and expiratory wheezes

24
Q

air embolism: intervention

A

call for help, position patient in trendelenburg on THEIR LEFT SIDE, administer oxygen, monitor VS, and have emergency equipment ready

25
Q

complications of IV therapy: fluid overload

A

too much fluid overloads the circulatory system

26
Q

complications of IV therapy: infection

A

localized or
systemic

27
Q

complications of IV therapy: phlebitis

A

irritation to vein; mechanical or chemical

28
Q

complications of IV therapy: infiltration

A

fluid seeps into tissue

29
Q

complications of IV therapy: extravasation

A

infiltration of any caustic medication into tissue

30
Q

chemical phlebitis:

A

inflammation of a vein associated with chemical irritation

31
Q

causes of chemical phlebitis:

A

too rapid of infusion, presence of particulate matter in solution, improper dilution or reconstitution when preparing meds, and administration of irritating meds

32
Q

prevention of chemical phlebitis:

A

use an in-line filter for meds that do not reconstitute completely, increase volume of dilution, CVAD or larger peripheral veins for IV site, slow the rate of infusion, and restart any questionable IVs

33
Q

infiltration:

A

fluid leak into tissue around the vein

34
Q

infiltration S&S:

A

does not irritate the tissue, pain or burning at IV site, skin tightness at site, blanching/coolness of skin, and dependent edema

35
Q

infiltration: interventions

A

stop infusion, remove IV line, place a new IV line, continue to monitor infiltrated site and call physician if needed

36
Q

extravasation:

A

infiltration of a vesicant drug

37
Q

S&S of extravasation

A

pain or burning at IV site, skin tightness at site, blanching/coolness of skin, and dependent edema

38
Q

____ are the safest for administration of vesicant drugs

A

CVADs

39
Q

extravasation: prevention

A

dilute meds as recommended, avoid use of high-pressure pumps, assess & monitor IV site, teach pt what to report

40
Q

venous spasm:

A

sudden, brief, tightening of muscle cells inside the vein

41
Q

causes of venous spasm:

A

viscous solutions, too rapid administration, cold or irritating solutions

42
Q

symptoms of venous spasm:

A

sharp pain at the IV site, pain radiating up the arm with the IV site

43
Q

prevention techniques of venous spasm:

A

dilute meds as recommended, admin solutions and meds at room temperature, admin at recommended rate, restart questionable IVs, and consider a warm compress during infusion

44
Q

IV push preparation example:

A

HCP ordered: ceftriaxone 1 gm IV daily

Pharmacy dispenses: 1 gm vial of ceftriaxone to be reconstituted in 10 mL sterile water

the nurse uses a sterile syringe with a blunt fill needle to access sterile vials

45
Q

IV push administration:

A

follow 7 rights, verify pt allergy/status, scan pt’s arm band, scan med vial and verify with eMAR (3rd check), HH & don clean gloves, remove alcohol permeated cap from IV lumen –> clean needle-less connector access with alcohol pad for 15 seconds

46
Q

IV push administration continued once you get ready to administer with syringe to catheter:

A

-purge air from a sterile saline flush -> attach syringe -> flush lumen & catheter with 9 mL -> remove syringe

-clean needle-less connector access -> attach medication syringe -> administer med at recommended rate -> remove syringe

-clean needle-less connector access -> attach post saline flush syringe -> flush slowly for the first 2-3 mL then vigorously for total of 9 mL

-remove flush syringe -> clamp lumen -> attach new alcohol permeated cap

47
Q

figuring drops per minute for gravity infusion:

A

total volume x drop factor/ time in minutes = gtts/minute

mL x gtts / min = gtts/min

48
Q

use ____ ____ included with the tubing delivery system to control the rate of administration

A

roller clamp

49
Q

IV gravity preparation:

A

activate vial & reconstitute the medication first -> insert and prime primary tubing to administer via gravity flow (prep of med can be done in med room or the pt room)

clamp tubing, remove protection cover from the “set” site on med bag -> remove protective cover from spike and aseptically insert the spike into the “set” site of the bag, squeeze and fill the chamber 1/3 to 1/2 full

slowly open the roller clamp and prime tubing to end port (leaving the protective cover on the tubing end)

50
Q

your primary fluid will be your _____,_____, or _____ solution; primary fluid is also called “___ __ ___” on the IV pump

A

isotonic, hypertonic, or hypotonic solution; guardrail IV fluids

51
Q

“_____ ______” programming are for your medication (abx, pain meds, etc.)

A

guardrail drugs

52
Q

avoid using ____ ____ on the IV pump because the smart pump can’t help with parameters of infusion.

A

“basic infusion”
