CCP 223 - Lab Analysis

Question 1

Weak acids are proton ___.

Answer 1

Donors.

Question 2

Weak bases are proton ____.

Answer 2

Acceptors.

Question 3

What is more sensitive for the screening of pancreatitis: Amylase or lipase?

Answer 3

Lipase.

Tip to remember: there is a ‘P’ in lipase.

Question 4

ABCD of ABG interpretation stands for:

Answer 4

A - Anion gap + albumin
B - Blood gas
C - Compensation
D - Declare hypoxemia

Question 5

What is the expected compensation ratios for the various types of metabolic/resp acidosis/alkalosis?

Answer 5

Met Acid 1:1
Met Alk 1:0.7
Resp Alk 1:0.5
Resp Acid 1:0.3

Question 6

Interpret this ABG:

7.38 / 63 / 100 / 32

Answer 6

Respiratory acidosis with a superimposed metabolic alkalosis.

Question 7

Define “anion gap”:

Answer 7

The difference between the sum of routinely measured anions (ie. sodium and potassium) and routinely measured cations (ie. chloride and HCO3).

Question 8

Causes of AGMA:

Answer 8

KULT, or MUDPILESCAT

Question 9

Normal anion gap is:

Answer 9

10 +/- 2

Question 10

Normal osmolar gap is:

Answer 10

≤ 10

Question 11

Anion gap is calculated using:

Answer 11

AG = Na - (Cl + HCO3)

Question 12

Causes of NAGMA:

Answer 12

1) RTA
2) GI losses
3) Hyperchloremia

Question 13

Causes of metabolic alkalosis:

Answer 13

1) Iatrogenic

2) Alkaline ingestion (ie. Tums)
