Which of the following actions is appropriate when transporting a specimen for ABG analysis?

Choice A reason:
Collecting the specimen in an SST (serum separator tube) is not suitable for ABG (arterial blood gas) analysis. SST tubes are used for chemistry tests that require serum separation after centrifugation and are not designed for the preservation of blood gases.

Choice B reason:
Placing the specimen in ice is the correct action when transporting a specimen for ABG analysis. Cooling the specimen slows down metabolic processes, which can alter the levels of gases and pH in the blood if not promptly analyzed. This is particularly important if there is a delay expected in the analysis of the ABG specimen.

Choice C reason:
Collecting the specimen in sodium citrate is not appropriate for ABG analysis. Sodium citrate is an anticoagulant used in coagulation studies and would interfere with the measurement of blood gases and pH levels in an ABG analysis.

Choice D reason:
Inserting the specimen in a light-resistant package is not a standard requirement for ABG specimens. While protecting specimens from light is important for certain types of tests, such as those for bilirubin, it is not necessary for ABG analysis.

Choice A Reason:
Pernicious anemia is a type of anemia caused by a deficiency of vitamin B12, which is not directly related to the volume of blood drawn. It is typically associated with the inability to absorb vitamin B12 from the gastrointestinal tract and is not a consequence of drawing blood.

Choice B Reason:
Iatrogenic anemia is the correct answer. It is a condition that can occur when too much blood is drawn from an infant, leading to anemia caused by medical intervention. Infants have a limited blood volume, and removing more than the recommended amount can significantly decrease their red blood cell count, resulting in anemia.

Choice C Reason:
Hyperthermia refers to an abnormally high body temperature, which is not a direct result of drawing blood. It is more commonly associated with environmental factors, infections, or other medical conditions that cause the body's temperature regulation to fail.

Choice D Reason:
Hypothermia is a condition where the body temperature drops below the normal range, which is also not a direct consequence of drawing blood. It is typically caused by prolonged exposure to cold temperatures and is unrelated to the volume of blood drawn from an infant.
