Which of the following items should a phlebotomist recognize as part of the aseptic technique protocol?
Standard precautions
Safety devices
Quality control logs
Disaster emergency plan
The Correct Answer is A
Choice A Reason:
Standard precautions are a set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin (including rashes), and mucous membranes. These measures are to be applied to all patients, regardless of their diagnosis or presumed infection status. Standard precautions include hand hygiene, use of personal protective equipment (PPE), respiratory hygiene/cough etiquette, safe injection practices, safe handling of potentially contaminated equipment or surfaces in the patient environment, and aseptic technique.
Choice B Reason:
Safety devices, such as needles with engineered sharps injury protections, are designed to prevent needlestick injuries and the transmission of bloodborne pathogens. While they are an important aspect of a phlebotomist's work, they are not specifically part of the aseptic technique protocol. Aseptic technique focuses on preventing contamination of sterile surfaces and materials to prevent infection.
Choice C Reason:
Quality control logs are records that document the performance of equipment and procedures to ensure they meet the required standards. They are essential for maintaining the integrity of laboratory results and ensuring patient safety. However, quality control logs themselves are not a component of the aseptic technique protocol, which is more concerned with the immediate prevention of infection during clinical procedures.
Choice D Reason:
A disaster emergency plan is a comprehensive document outlining the actions to be taken in case of an emergency. This plan is crucial for ensuring safety and continuity of care during unexpected events but is not related to the aseptic technique protocol. Aseptic technique is a method used to prevent infection during medical procedures by maintaining a sterile environment.

Correct Answer is B
Explanation
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 D
Explanation
Choice A reason:
The Apgar score is a quick test performed on a newborn at 1 and 5 minutes after birth. The 1-minute score determines how well the baby tolerated the birthing process. The 5-minute score tells the healthcare provider how well the baby is doing outside the mother's womb. While it is an important indicator of a newborn's health, it does not directly influence the calculation of total blood volume.
Choice B reason:
Height is a measure of the length of a person's body. In the context of a 2-day-old infant, height is not a practical or necessary measurement for determining blood volume. Blood volume is more closely related to weight than to height, especially in the case of infants.
Choice C reason:
Head circumference is a measurement of the size of a child's head and is used to monitor brain growth. While it can provide valuable information about a child's development, it is not used to calculate blood volume. The total blood volume of an infant is not determined by the size of the head but rather by the overall weight.
Choice D reason:
Weight is the correct factor to consider when calculating total blood volume for a full-term, 2-day-old infant. The standard formula to estimate an infant's total blood volume is approximately 80 {mL/kg} of body weight. Therefore, knowing the infant's weight in kilograms is essential for this calculation.
