Drawing more than the recommended amount of an infant's blood volume may result in which of the following conditions?
Pernicious anemia
Iatrogenic anemia
Hyperthermia
Hypothermia
The Correct Answer is B
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.

Correct Answer is A
Explanation
Choice A reason:
Occult blood detection is not a process that occurs naturally after a venipuncture to control bleeding. It is a laboratory test used to detect blood in the stool that is not visible to the naked eye. This test is unrelated to the venipuncture process.
Choice B reason:
The term "Phlebotomists" refers to healthcare professionals who perform venipuncture. It is not a process but a profession. Therefore, it does not fit the context of the question regarding the control of bleeding after venipuncture.
Choice C reason:
Hematopoiesis is the process of creating new blood cells in the body and occurs in the bone marrow. While it is an ongoing process essential for replenishing the body's blood supply, it is not directly related to controlling bleeding after a venipuncture.
Choice D reason:
Hemoconcentration is a condition where the blood concentration of cells and solids is higher than normal, usually due to a loss of plasma. This can occur during venipuncture if the tourniquet is left on for too long, but it is not a process used to control bleeding.
Correct Answer is C
Explanation
Choice A reason:
A 16-gauge needle is quite large and is typically used for rapid fluid administration or blood donation in adults. It is not suitable for pediatric patients due to the size of their veins and the potential for causing trauma and discomfort.
Choice B reason:
An 18-gauge needle is also large and commonly used for adult patients in situations where larger volumes of blood are needed quickly. For a 6-year-old patient, this gauge would be too large and could cause significant pain and increase the risk of damaging the vein.
Choice C reason:
A 23-gauge needle is recommended for pediatric patients, including those who are 6 years old. It is small enough to minimize discomfort and the risk of injuring the vein, yet it allows for adequate blood flow for collection³. This size needle is often used with a winged infusion set, which is suitable for the smaller, more fragile veins of pediatric patients.
Choice D reason:
A 27-gauge needle is very small and is typically used for intradermal injections or for very small veins, such as those in neonates. While it would cause minimal discomfort, it may not provide an adequate flow rate for venipuncture in a 6-year-old patient.
