A

Electrolytes; dehydration

28

May occur in combination with other imbalances. Name 6 causes for FVD.

A
  1. fluid loss from vomiting
  2. diarrhea
  3. GI suctioning
  4. sweating
  5. decreased intake

30
Q

Functioning IV therapy:

What are the three types of IV therapy?

A

Maintenance

Replacement

Restoration

31
Q

Funtions of IV Therapy: Maintenance

Mainly for those who are _____ and/or ______. (Remember insensible loss.) ______cc fluid/sq meter of body serface.

A

NPO; stressed 1500

32
Q

Function of IV therapy: Maintenance

For maintenance fluids what is given and why?

A

glucose, Na+, K+, H20

Maintenance supplies calories, sparing protein, minimized ketone formation.

33
Q

Function of IV therapy: Replacement

Replacement therapy is used for long term ____. Usually D/C’d in ___ hours. Replaces fluids when body can’t maintain requirements. Will probably need ______

A

NPO; 48; potassium

34
Q

Function of IV therapy: Replacement

What people will need replacement therpay?

A

GI surgeries, N/V, diarrhea, tissue injuries, major surgeries, wound infection.

35
Q

Function of IV therapy: Replacement

As nurses what should we look for?

A

Check Urine and output >30ml/hr for 48hrs

36
Q

Function of IV therapy: Restoration

Used for restoration on ongoing basis- greater than ___hrs. Similar to replacement except need: strict _____, daily labs for _________. type of fluids depends on type _____

A

48; I&Os, electrolytes; lost

37
Q

Function of IV therapy: Restoration

Who may need restoration therapy?

A

people with abscesses, NG tube, burns, large abd wounds.

38
Q

Factors affecting IV therapy:

Name 5 things that may affect IV therapy.

A
  1. age- elderly, babies (#1)
  2. health status
  3. fluid balance
  4. development of complications- draining wounds
  5. equipment-pump, controller
39
Q

IV influencing Factors:

What are the 4 influencing factors?

A
  1. Nurse practice act- only RNs can hang blood
  2. institutional guideline- read guidlines at facility
  3. centers for disease control (CDC)
  4. IV Nurses Society- set rules
40
Q

Vascular Access devices:

  1. Peripheral
  2. Midline
  3. Peripherally inserted Central Venous Catheter (PICC)
  4. Central venous catheter (CVC)
  5. Short term non-tunneled
  6. Long term tunneled
  7. hickman, broviac
  8. implanted port
  9. groshong
  10. Others: dialysis, intraoscous (inside bone), intrathecal
A

Some meds can damage the veins and must be administered through other routes instead of the normal IV peripheral route. PICC line removal you will use a slow stop/start method, an antibacterial cream may be used. It must also be measured after to ensure it was removed intact. If it is not intact upon removal must notify MD so an x-ray must be done to find the remaining catheter that may be inside the body.

41
Q

PICC line placement: take 15 seconds to review image. A PICC is advanced through the cephalic or basilic vein to the axillary, subclavian or brachiocephalic vein or the superior vena cava

A
42
Q

Tunnel: take 15 secs to study image.

A
43
Q

Portacath: take 15 sec to study image

A
44
Q

IV Solutions:

Name the 3 cystalloid solutions:

A
  1. hypotonic
  2. isotonic
  3. hypertonic
45
Q

IV solutions:

What are exapanders? name them.

A

Colloids; blood, albumin, hespan

46
Q

Solutions: hypotonic (<250 mOsm/L)

Action: hydrates cell by pulling H20 into ______ spaces from _______ space.

A

cellular; vascular

47
Q

Solutions: Hypotonic (<250 mOsm/L)

Indication: treatment of ______ dehydration.

Concerns: may exaggerate _______ due to fluid shifting out of vascular space.

What patient would we NOT give this to?

A

hypertonic; hypotension

ANS: Brain injury it can cause cerebral edema, we would give manitol

48
Q

Solutions: Isotonic (250-375 mOsm/L)

Action: hydrates ________ compartment; replaces volume without disrupting ________ and ________ volumes.

A

intravascular;intracellular; interstitial

49
Q

Indications: treatment of ______ dehydration. replaces ____

A

vascular;NaCl

50
Q

concerns: use cautionusly in patients who are fluid-______ or who would become compromised if vacular volume would _______ such as cardiac/renal patinets.

A

overloaded; increase
