Q

Which organ is responsible for the production of the following enzymes?
How are these enzymes transported?

(ALT) - Alanine Transaminase

(ALP) - Alkaline Phosphatase

A

The liver is responsible for the creation of:

(ALT) - Alanine Transaminase

For every 10 mmHg change in CO2, the pH will change 0.08 in the opposite direction.

108
Q

A

CPK-MM - Creatine Phosphokinase - Skeletal Muscle

CPK-BB - Creatine Phosphokinase - Brain

CPK-MB - Creatine Phosphokinase - Cardiac

Normal Range Value: 5 - 35 mcg/mL

109
Q

What does the Blood Urea Nitrogen (BUN) panel represent physiologically?

A

The Blood Urea Nitrogen (BUN) panel physiologically represents the metabolic byproduct created from the breakdown of blood, muscle, and protein.

110
Q

You are asked to to run a CBC for a patient. What does the CBC evaluate?

A

Complete Blood Count - used as a broad screening test to check for a variety of conditions including anemia and infections.

WBC - White Blood Count: 4,500 - 11,000 /mL
WBCd - White Blood Count Differential: 40 - 70%
RBC - Red Blood Cell Count: 3.5 - 6M /mL
HGB - Hemoglobin: 15 g/dL
HCT - Hematocrit: 44%
Platelet Count - 150,000 - 400,000/mm3

111
Q

A

Metabolic acidosis is characterized as:

pH decreased
PaCO3 no change
HCO3 decreased

112
Q

What is the normal value range for the Blood Urea Nitrogen (BUN) panel?

A

The normal value range for the Blood Urea Nitrogen (BUN) panel is:

7 - 21 mg/dL

113
Q

What is occurring if the pH is down and the PaCO2 is elevated?

A

Respiratory acidosis has occurred if the pH is down and the PaCO2 is elevated.

Think Seesaw

114
Q

Your patient has an elevated ammonia (NH3) level. What is this indicative of and why?

A

Elevated ammonia (NH3) levels are indicative of liver damage/failure.

With liver damage, the liver may be unable to convert ammonia into urea causing an increase of NH3 levels.

NH3 Standard Value Range: 15 - 45 mcg/dL

115
Q

What are the two main mechanisms leading to hypercapnia?

A

The two main mechanisms leading to hypercapnia (excessive carbon dioxide) are:

  1. Hypoventilation
  2. Ventilation / Perfusion mismatch (V/Q mismatch)
116
Q

What does a Base Excess (BE) of +3 to -3 mmol/L indicate?

A

+3 to -3 mmol/L is considered a normal Base Excess (BE).

117
Q

What is occurring if the pH and the HCO3 are down?

A

Metabolic acidosis has occurred if the pH and the HCO3 are down.

118
Q

What is the normal Arterial Blood Gas (ABG) range for pH (per Hydrogen)?

A

The normal Arterial Blood Gas (ABG) range for pH (per Hydrogen) is:

7.35 - 7.45

119
Q

What does the D-dimer Assey assess?

A

D-dimer assesses for clot formation.

** NOT specific - will NOT indicate the location of the clot **

Normal Range Value: < 0.5 - 1 mcg/mL
< 500 - 1000 mcg/L

120
