Answer 8

50-70%
20-50%
2-12%
0-7%
0-2%

Question 9

Platelets

Answer 9

150,000-400,000 L (150-400x103 uL)

Answer 11

3.5-5.0 mEq/L

Question 12

Calcium (Ca)

(gallon of milk)

Answer 12

8.5-10.5 mg/dL

A gallon of milk weighs about 8.5 pounds.

Then think of 2% milk to help you remember to add 2 to the 8.5.

(smallest)

Answer 13

1.5-2.5 mEq/L

Question 14

Chloride (Cl)

(hot tub)

Answer 14

95-105 mEq/L

When you think of chloride, think of chlorine in a hot tub.

The average temperature of a hot tub is 95-105 degrees Fahrenheit.

Question 15

Phosphate (PO4)

(relationship to calcium)

Answer 15

2.5-4.5 mg/dL

Calcium and phosphate have inverse relationship in the body

Calcium’s low value is 8.5

Take away the .5’s and focus on the 8 and it will help remember that phosphate’s ranges are 2 x 4

Question 16

Glucose (fasting)

Answer 16

75-110 mg/dL (may see 120) *70-90 for fasting

Question 17

Creatine Kinase (CK)

Answer 17

20-200 U/L *female 20-180

Question 18

Creatine kinase MG (CK-MB)

Answer 18

<0.4-0.6

Question 19

Answer 19

<0.1 ng/mL

Question 20

Brain Natriuretic peptide (BNP)

Answer 20

Question 21

NT-proBNP

Answer 21

<400pg/mL (values increase with age higher in women than men)

Question 22

International normalized ratio (INR)

Answer 22

0.8-1.2

You can use the letter “I” in INR to remember the number 1 (values around 1)

Question 23

Partial thromboplastin time (PTT) *aPTT is more sensitive version of PTT

Answer 23

21-35 secs

You can use the first “T” to remember “Ten” and the second “T” to remember “Twenty/Thirty”

Question 24

Prothrombin time (PT)

Answer 24

10-16 sec, 11-13sec

You can use the “T” in PT to remember “Ten”

Question 40

HCO3
(Carbonation & soda)

Answer 40

22-26 mEq/L or 24-28 mEq/L

When you think of bicarbonate, think of carbonation and soda.

Soda is usually sold in a 12 pack.

However, it’s bicarbonate so we need to multiply the 12 by 2 (BI = 2).

This gives us 24, which will help us remember the normal range of 23-29 mEq/L.
