Order of Draw for NHA.

A.

Blood Culture, light blue, red, red-gray/gold tube, green, lavender,gray
B.

Blood Culture, light blue, red-gray, gray, lavender, green
C.

Light blue, gray, green, red, red-gray/gold, lavender, blood cultures
D.

None of the above

Correct Answer
A. Blood Culture, light blue, red, red-gray/gold tube, green, lavender,gray

Explanation
The correct answer is the order of draw for NHA is Blood Culture, light blue, red, red-gray/gold tube, green, lavender, gray. This order is important to prevent cross-contamination and ensure accurate test results. Blood cultures are drawn first to minimize the risk of contamination from other tubes. Light blue tubes are used for coagulation tests, followed by red tubes for serum chemistry tests. The red-gray/gold tube is used for serum separator tests, green tubes are used for plasma separator tests, lavender tubes are used for hematology tests, and gray tubes are used for glucose tests. This order ensures that the correct additives are used for each test and prevents any interference between tubes.

What specimen would need to be transported in a heat block?

A.

Cryofibrogen
B.

BUN
C.

PTT
D.

Billirubin

Correct Answer
A. Cryofibrogen

Explanation
A heat block is used to maintain a specific temperature for certain specimens during transportation. Cryofibrinogen is a protein that can precipitate and form clots at low temperatures. Therefore, it needs to be transported in a heat block to prevent clot formation and maintain its integrity. BUN (blood urea nitrogen), PTT (partial thromboplastin time), and bilirubin do not require specific temperature control during transportation, so they would not need to be transported in a heat block.

All of the following are symptoms of Shock except.

A.

Decrease in breathing
B.

Pale skin
C.

Expressionless face
D.

Cold and clammy skin

Correct Answer
A. Decrease in breathing

Explanation
Shock is a life-threatening condition that occurs when there is inadequate blood flow throughout the body. Symptoms of shock include pale skin, an expressionless face, and cold and clammy skin. These symptoms are caused by a decrease in blood flow and oxygen delivery to the body's tissues. However, a decrease in breathing is not a symptom of shock. In fact, in shock, the body often compensates by increasing the respiratory rate in an attempt to improve oxygenation.

What is the correct site for a Infant heel puncture?

Correct Answer
Interior side of the heel

Explanation
The correct site for an infant heel puncture is the interior side of the heel. This location is chosen because it is less likely to cause damage to important structures such as bones and nerves. Additionally, the interior side of the heel has a good blood supply, making it easier to collect a blood sample for testing.
