What is <7.35

What is markers for renal function. (fyi: in severe kidney disease, K may be elevated)

What is 3 days or up to 4 months for a newborn

What is elevated or decreased

cortisol should be elevated during stress (ie-after surgery). if we test & it's normal, the body's endogenous catecholamines might be lacking, so we give the patient hydrocort to mimic the natural response

What is normal pH

What is markers for liver function

only prbc's. a type and screen is good for plasma for 6 months

a left shift means the body is pumping out more wbc's quickly because they are needed to fight infection so they are in the blood stream at an earlier stage of development (bands, meta, myelo, pro, band)

elevated amylase/lipase show pancreatitis; common after lymphatic intervention or with other GI abnormalities

Lactate accumulates when there is inadequate O2 delivery. the body is stressed. early warning for diminished cardiac output

BNP is increased in heart failure, it's released with the "stretch" of the heart

What is ab negative

What is c reactive protein. it is made by the liver and released in response to inflammation. it is a blind marker & can also be elevated in trauma, heart attack, infection, chronic inflammatory disease, cancer

newborns, especially preemies, can "spill bicarb" into their urine, making them appear falsely acidotic. the kidneys aren't reabsorbing the bicarb (normal process), so when the urine (normally acidotic) contains bicarb, the pH will be higher

What is respiratory insufficiency (too little rate or too little volume; sleepy, needs more breaths, atelectasis, effusion)

urine output of less than 0.5 mL/kg/hr can indicate poor renal function or perfusion

a positive antibody screen means the baby has made an antibody to a certain rbc antigen. once it is known, the patient must receive that antigen negative blood.

it is produced by many cells in the body, often in response to infection or injury; significantly increased with bacterial infections and sepsis

What is chloride (too low, loop diuretics, Lasix, won't work)

a venous co-ox is generally ordered to look at the mixed venous sat, which is a marker of heart failure. (arterial co-ox may be ordered to check for methemoglobin for iNO toxicity

elevated coags in absence of anticoagulant therapy indicates liver damage

when an infant is listed for incompatible heart transplant, this shows how much antibody the baby makes against different blood types

culture bottle top should always be wiped with an alcohol pad, the blood culture is always transferred first!!! , it is collected prior to start of antibiotics

What is low cardiac output, sepsis, hypothermia, inadequate systemic, metabolic disease, altered glucose metabolism (high or low), preemie kidney disease, liver failure, seizures, renal failure
