Question 1

Why is capillary puncture less desirable for blood gas analysis?

Answer 1

This is because capillary puncture has its partial arterial composition and is temporarily exposed to air during collection, which can alter test results

Question 2

These are rarely collected on adults

Answer 2

Capillary gas specimens

Question 3

These are collected from the same sites as routine capillary puncture specimens

Answer 3

Capillary blood gas specimens

Question 4

What will increase if you warm the site before blood collection

Answer 4

Blood flow and arterialize the specimen

Question 5

How many mins should you warm the site?

Answer 5

5-10 mins

Question 6

Who are commonly tested to detect and monitor increased bilirubin levels caused by overproduction or impaired excretion of bilirubin?

Answer 6

Neonates (newborns)

Question 7

What is associated with overproduction of bilirubin from accelerated red blood cell hemolysis?

Answer 7

Hemolytic disease of the newborn (HDN)

Question 8

Impaired bilirubin excretion often results from?

Answer 8

Temporary abnormal liver function

Question 9

Impaired bilirubin excretion often results from temporary abnormal liver function commonly associated with?

Answer 9

premature infants

Question 10

High levels of bilirubin result in?

Answer 10

Jaundice (yellow skin color)

Question 11

In infants, bilirubin can cross ?

Answer 11

blood-brain barrier

Question 12

At what rate is transfusion needed if levels increase in infants?

Answer 12

at a rate equal or greater than 5.0 mg/dL per hour or when levels exceed 18.0 mg/dL

Question 13

Bilirubin breaks down in the presence of ?

Answer 13

light

Question 14

In what light are jaundice infants placed under to lower bilirubin levels?

Answer 14

Special ultraviolet lights

Question 15

In infants, how are bilirubin specimens collected?

Answer 15

heel puncture

Question 16

What color of microcollection containers is used to reduce light exposure that will protect a bilirubin specimen from effects of ultraviolet light?

Answer 16

Amber-colored

Question 17

The blood-filled circles are often referred to as?

As many as — different disorders can be detected in the blood spots on one form

Answer 18

30

Question 19

What are some disorders tested in NBS?

Answer 19

• Phenylketonuria (PKU)
• Hypothyroidism
• Galactosemia

Question 20

Disorders tested in NBS: – genetic disorder characterized by a defect in the enzyme that breaks down the amino acid phenylalanine, converting it into the amino acid tyrosine

Answer 20

Phenylketonuria (PKU)

Question 21

Disorders tested in NBS: - insufficient thyroid hormones that can affect brain development (e.g., Thyroxine and thyroid stimulating hormone)

Answer 21

Hypothyroidism

Question 22

Disorders tested in NBS: – inherited disorder by lack of the enzyme needed to convert milk sugar galactose into glucose

Answer 22

Galactosemia

Question 23

What technique is always a must before making an incision or puncture?

Answer 23

Aseptic

Question 24

It is a drop of blood spread thin on a microscope slide

Answer 24

Blood film or smear

Question 25

It is required to perform a manual differential (Diff), a test in which the number, type, and characteristics of blood cells are determined by examining a stained blood smear under a microscope

Answer 25

Blood smear or film

Question 26

It may be performed as part of a complete blood count or to confirm abnormal results of a machine-generated differential or platelet count

Answer 26

Manual differential

Question 27

How many blood smears are normally prepared and submitted for testing?

Answer 27

two

Question 28

What test usually requires four fresh peripheral blood (blood from an extremity) smears?

Answer 28

Leukocyte alkaline phosphatase (LAP)

Question 29

When collected with other skin puncture specimens, what should be collected first to avoid effects of platelet clumping?

Answer 29

Blood smears

Question 30

Wiping away the first blood drop removes?

Answer 30

excess tissue fluid and alcohol residue that could distort cell morphology
