Why are ADH and aldosterone secreted?

A

Retain sodium and water with aldosterone
Retain water with ADH
–> Blood volume will go up

Q

Explain the parkland formula for fluid replacement.

A

(4ml of LR) X (weight in kg) X (%of TBSA burned) = total fluid replacement for first 24 hours

1st 8 hours = 1/2 total volume
2nd 8 hours = 1/4 total volume
3rd 8 hours = 1/4 total volume

Q

A client’s respirations are shallow. They are retaining _____ and therefore they are in respiratory acidosis.

20
Q

Why is albumin given to the burn patient?

A

Holds onto fluid in the vascular space (can’t give for first 24 hours)
Increases vascular volume, kidney perform, BP, cardiac output).

21
Q

In a client who is receiving fluids rapidly, which is a measurement you could take hourly to ensure you’re not overloading the client?

22
Q

What are the 2 immunizations given to burn patients?

A
  1. Tetanus toxoid

2. Immune globulin

23
Q

Relieves the pressure and restores the circulation, cuts through the eschar.

A

Escharotomy

24
Q

Relieves the pressure and restores circulation but the cut is much deeper into the tissue, the cut goes through the eschar and the fascia.

A

Fasciotomy

25
Does a burn patient have a foley?
Yes - check output hourly
26
What would you do if the urine was brown or red?
Call doctor
27
What drug might be ordered to flush out the kidneys?
Mannitol | never put in fridge, inspect in light for crystals
28
What electrolyte imbalance is a burn patient at risk for?
Hyperkalemia (cells split up and releases potassium)
29
Why would a physician want a burn patient to be NPO and have an NG tube hooked to suction?
Patient could develop a paralytic ileus due to decreased vascular volume and hyperkalemia. NG tube removed when BS X 4 quads
30
Classification of burns: | Damage only to epidermis
Superficial thickness
31
Classification of burns: | Damage to entire epidermis and varying depths of the dermis
Partial thickness
32
Classification of burns: | Damage to entire dermis and sometimes fat
Full thickness
33
What are 2 specific measures for a patient who has burns on their hands?
1. Wrap each finger separate | 2. Use splints to prevent contractures
34
Should a client with burns on their head or neck use a pillow?
No - promotes chin to chest
35
What 2 things like to grow in eschar?
Bacteria and fungus | Necrotic tissue must be removed
36
What type of isolation is used with burn patients?
Reverse isolation
37
What are the 2 enzymatic drugs used to eat dead tissue?
1. Sutilanis (Traverse) | 2. Collagenase (Santyl)
38
Can be used to debride. Give pain medication to patients at least 30 minutes prior. Worry about cross contamination.
Hydrotherapy
39
What are the 4 common drugs used with burns?
1. Silver sulfadizine (silveadene) 2. Mafedine acetate 3. Silver nitrate 4. Povidone-iodine (betadine)
40
What 3 things must be monitored when giving -mycin drugs?
1. BUN 2. Creatinine 3. Hearing loss (ototoxicity and nephrotoxicity - assume they are toxic if BUN and Cr are increasing)
41
Removes the dead burned tissue and takes good skin from a healthy donor site (usually the buttock or thigh).
Grafting
42
What should be done first when someone has suffered a chemical burn?
Remove patient from chemical Remove contacts Flush for 15-20 minutes for body; 30 minutes for eyes
43
How many wounds occur from an electrical burn?
