Too much volume in the vascular space | Hypervolemia aka FVE aka Fluid Volume Excess; |
Causes of FVE (Hypervolemia) | CHF, Renal Failure, Alkaseltzer, Fleets enema, IVF w/Na, and Aldosterone |
Alkaseltzer, Fleets ememas, and IVF w/Na have a lot of what? | Na which in turn retains fluid in the vascular space |
Where does aldosterone live? | Adrenal glands |
What is the normal action of aldosterone? | When blood volume gets too low (vomiting, blood loss, etc.) aldosterone is kicked in which makes the body retain NA and H2O which increases blood volume |
What are some dx with too much aldosterone? | Cushings and hyperaldosterone (Combs) |
What is a Dx with too little aldosterone? | Addison's (add steroids) |
Aldosterone = | Na and H20 |

What does ADH do to the body? | Makes the body retain H20 |
What are 2 ADH problems? | Too much and too little |
Too much ADH causes what? | Body retains H20 - creating FVE, SIADH can occur (too much H20), UO decreased and blood becomes dilute |
What happens with too little ADH? | Body loses H20 (diureses), creating FVD, DI can occur, UO increases and blood is concentrated |

Isotonic = | Goes into vascular spave and stays there! |
Examples of Isotonic solutions: | NS, LR, and D5W |
Hypotonic = | They go into hte vascular space, rehydrate, then move into the cell and the cell burns the remainder up in cellular metaboism. They do hydrate, but they won't drive your pressure up b/c they don't stay in the vascular space |

What are the 2 major chemicals that must be remembered? | Bicarb (base) and H, CO2 (acid) |
What is the "lung chemical"? | CO2 (acid) |
What is the "Kidney chemical"? | Bicarb and H (base and acid) |
There is only one way to get rid of CO2 - what is it? | Exhale |
Bicarb, H+, and CO2 can either make you sick or compensate. It depends on what? | On which IMBALANCE you have. |
In Respiratory acidosis/alkalosis, which organs are sick? | Lungs |
During a chemical imbalance in the lungs - what organ compensates? | The kidneys |
What are the chemicals the kidneys use to compensate with? | Bicarb and H+ |
In matebolic acidosis/alkalosis - which organs are sick? | Kidneys |
During a chemical imbalance with the kidneys - what organ compensates? | Lungs |
What is the only chemical the lungs have to compensate with? | CO2 acid |
Do the lungs compensate slowly or quickly? | Quickly |
Do the kidneys compensate slowly or quickly? | Slowly (3 days - but efficient) |
What is Normal pH? | 7.35 - 7.45 (7.40) |
In Metabolic Acidosis, what is sick, and what compensates? | Kidneys are sick, lungs compensate |
In Respiratory Acidosis, what is sick, and what compensates? | Lungs are sick, Kidneys compensate |
In Metabolic Acidosis What happens to the RR and why? | RR increases to blow off CO2 |
In Resp Acidosis, what do the kidneys do to compensate? | Retain/secrete Bicarb into the blood stream |
In figuring out if something is Metabolic or Respiratory, what do you always need to remember? | If all arrows are the same = M. If arrows are different = R. Look at pH level to determine if Acid or Alka |
In Meta Alka, what is sick? | Kidneys |
In Resp Alka, what is sick? | Lungs |
In Resp Acid, what is the problem chemical? | too much CO2 (acid) = RR too shallow or pt not breathing = kidneys will compensate |

What's the first thing you think of with a restless pt? | Early Hypoxia!! |
Cyanosis + Bradycardia = | Late Hypoxia!! |
With a Hysterical pt, think? | Resp Alkalosis (hypERventilation) |
With Resp Alka, how do you treat? | The kidneys will take 3 days to compensate, therefore have pt breathe into paperbag to force them to take back in CO2. Sedate pt if needed to slow down RR |
If a pt is starving, what do you think? | Meta Acidosis. The fat is being broken down, therefore producing keytones, and keytones are acid |
When a pt is vomiting, what do you think? | The body is losing acid, leaving the pt alkaline, therefore Meta Alkalosis |
Pneumothorax = | Resp Acid |
Pneumonia = | Resp Acid |
Alka Seltzer / Antacids = | Meta Alka |
NG to suction = | Meta Alka |
Contusion to lung parenchyma = | Resp Acid |

When does the majority of plasma seepage occur with a burn? | In the first 24H |
Why does a pt's pulse increase with a burn? | Anytime you're in a FVD, pulse increases to compensate |
What does the UO decrease with a burn pt? | Kidneys are either trying to hold on or they aren't being perfused |
What is epi secreted in a burn pt? | Makes the ot vasoconstrict, shunts blood to vital organs |
Why are ADH and aldosterone secreted with a burn pt? | to retain Na+ and H20 with aldosterone and retain H20 with ADH = therefore the pt's blood volume will go up |
What is the most common airway injury with a burn pt? | Carbon Monoxide poisoning |
Tell about CO binding with burn pt's | Normally O2 should bing w/hemoglobin. CO can run much faster then O2...therefore, it gets to the hemoglobin 1st & binds |
Can CO levels be determined with a pulse Ox (pulse sat)? | NO, the pulse ox just shows how much hemoglobin is bound - but bound to what we don't know |
What determines how much CO is bound in a burn pt? | Carboxyhemoglobin; blood test to determine carbon monoxide poisoning |
If pt is hypoxic, what is the Tx? | 100% O2 (the ONLY time a pt is allowed 100% levels) |
Why should you always determine where a burn occured? | If open space, <chance of CO poisoning. If closed place, >chance of CO poisoning |
When you see a pt with burns to the neck / face / chest you had better think of what? | Airway! May need to intubate then trach |

One of the most important aspects of burn mgmt is what? | Fluid Replacement |
Why is albumin given after a major burn? | Albumin holds onto fluid in the vascular space |
What effect does albumin have on the kidneys w/ a burn pt? | It increases kidney perfusion |
What effect does albumin have on BP w/ a burn pt? | Increases BP |
What effect does albumin have on Cardiac Output w/ a burn pt? | Increases CO |
When giving a burn pt albumin, why do you really have to watch the heart? | When you give albumin, the vascular volume will increase, therefore increasing the workload of the heart. The heart could be stressed, causing FVE |
If FVE happens with a burn pt, what happens to the cardiac output? | It decreases. You will hear wet, crackle sounds |
On any pt who is receiving fluids rapidly, what must be monitored so overload does not occur? | CVP (Cardia Vascular Pressure) |
Why is it important to know what time the pt's burn occured? | Fluid therapy (for the 1st 24H) is based on the time the injury occured, not when Tx was started |
If a burn pt's CVP increases suddenly during IV fluids, what do you watch for? | R sided Heart failure |
What is the Parkland Formula for Burn Pt's? | Calculate what is needed for the first 24H and give 1/2 of it during the first 8H, 1/4 of the total volume the 2nd 8H, then the remaining 1/4 the 3rd 8H |
To calculate fluid replacement for burn pt's (Parkland Formula) what do you need to know? | The pt's weight in kg and TBSA (total body surrface area) |
If a burn pt is restless, what 3 things could it mean and which is PRIORITY? | Fluid replacement is inadequate, pain or hypoxia. Hypoxia is priority |
Always check what to determine if a burn pt's fluid volume is adequate? | UO |
A pt was given only 5mg of Morphine when the order was for a max of 10mg. Why did the nurse do this? | The pt's RR is shallow; give the least amt first; use judgement |
Why are IV pain meds preferred over IM with burns? | They act faster. No muscle with good perfusion for IM |
Why is a burn pt given a tetanus toxoid + the immune globulin? | For antibodies |
Explain the Tetanus Toxoid shot with burn pt's? | Active immunity; takes 2-4 weeks to get the AB's |
Explain the Immune Globulin with burn pt's? | Passive immunity; think immediate protection |
Does more death's occur with upper or lower body burns? | Upper; b/c of airway |
A pt has a circumferential burn on their arm. What does this mean and what should you be checking? | a burn all the way around the arm and cuts off circulation. Check skin color, skin temp, capillary refill, and pulse |
If a pt's vascular checks in his burned arm (circumferential) are bad, the Dr may do what procedure to relieve pressure? | Escharotomy or Faciotomy |
A pt was wrapped in a blanket to stop the burning process. Since the flames were gone does that mean the burning process had stopped? | No (apply cool H20 also) |
What purpose does blankets on a burn pt do? | Stops the flames, holds in body heat and keeps out germs |
Can ice be put on burns? | NO, ice will cause vasoconstriction therefore cutting off circulation |

What things do you look for to determine if any airway injury has occured w/ a burn pt? | Soot on face, dark sputum, synged facial/nasal hair |
Is a foley inserted with burn pt's | Yes and measured hourly. Brown/red UO is normal after a major burn, but still worry |
Is it possible that when you insert a foley on a burn pt that no urine will return? | Yes due to kidneys attempting to conserve the fluid or not perfusing properly |
What drugs might be ordered for a burn pt to help kidneys perfuse? | Lasix, Butnex, Dobuatonine, Dopamine |
Why will a burn pt start to diurese after 48H? | Because the fluid is going back into the vascular space. Now worry about FVE. UO should increase during this time |
K+ always like to live where? | Inside the cell |
Pot is IN, Na+ is OUT | Pot is IN, Na is OUT |
With a burn, what happens to the cells? | Rupture |
What happens to serum K+ levels during a burn? | It increases. The K+ seeps out of the cell and into the vascular space |

What are the S/S of Hypoglycemia? | Cold, clammy, weakness, nervous, increased pulse, nausea, confusion, headache |
What should the pt with hypoglycemia do? | Eat a simple sugar fast |

Diabetes + illness = | DKA |
With every drop in BS, pt loses what? | Few brain cells |
What are the IVFs with a pt in DKA? | Start w/NS, then when BS gets down to about 300 switch to D5W to prevent throwing the pt into Hypoglycemia (anticipate the Dr will order Ka+ to the IV solution at some point) |
