Question 1

The amount of blood collected from infants must be documented to avoid:

Accepted Answer

Iatrogenic anemia can occur in infants due to excessive blood collection for diagnostic testing. It's important to carefully document and limit the amount of blood drawn to prevent this condition. Hemolytic disease of the newborn and sickle cell anemia are not caused by blood collection.

Question 2

Excessive massaging or squeezing of the heel during a skin puncture procedure can cause:

Accepted Answer

Excessive massaging or squeezing can damage the heel, cause hemolysis by forcing blood through the puncture site, and introduce tissue fluid, contaminating the sample.

Question 3

Which of the following is the safest area for infant heel puncture? The:

Accepted Answer

The fleshy areas on either side of the heel are considered the safest areas for an infant heel puncture. This is because these areas avoid bone and minimize the risk of injury to the infant.

Question 4

Concerns that must be considered when collecting blood specimens from elderly patients include changes to the following as a result of advanced age:

Accepted Answer

Changes in sight, hearing, and skin are all concerns that must be considered when collecting blood specimens from elderly patients due to the physiological changes that occur with advanced age.

Question 5

Which of the following tests is required by law for neonatal screening?

Accepted Answer

Phenylketonuria (PKU) and congenital hypothyroidism are commonly included in mandatory newborn screening programs to prevent the severe consequences of untreated conditions.

Question 6

Precautions that must be taken to protect the skin and veins of elderly patients during blood collection include:

Accepted Answer

All the options listed are correct precautions to take when collecting blood from elderly patients. Elderly patients often have less elastic skin and more delicate veins, making them more susceptible to injury during blood collection. Careful anchoring of veins can prevent rolling and subsequent injury, applying pressure for a longer period can prevent excessive bleeding due to slower clotting times, and using smaller gauge needles and specialized equipment can minimize bruising and injury to fragile veins.

Question 7

It is necessary to control depth of lancet insertion during heel puncture to avoid:

Accepted Answer

Controlling the depth of lancet insertion during a heel puncture is crucial to avoid bone injury, as going too deep can harm the underlying bone structures.

Question 8

Which test is used to screen for hemolytic disease of the newborn?

Accepted Answer

Bilirubin testing is used to screen for hemolytic disease of the newborn, as this condition can lead to an increase in bilirubin levels due to the breakdown of red blood cells.

Question 9

Which test is used to screen infants for the inability to digest a sugar found in milk?

Accepted Answer

The Galactose test is used to screen infants for galactosemia, a condition where the body is unable to process galactose, a sugar found in milk.
