A phlebotomist is preparing to perform venipuncture on a patient who had a right-sided mastectomy. Which of the following is the correct site to perform the collection?
Left antecubital
Right cephalic
Left femoral artery
Right basilic
The Correct Answer is A
Choice A reason:
The left antecubital area is the correct site to perform venipuncture on a patient who has had a right-sided mastectomy. It is recommended to avoid the side of the mastectomy due to the risk of lymphedema and other complications associated with the removal of lymph nodes during the surgery. The left antecubital fossa, which is the area in front of the elbow, is a common site for venipuncture and is generally safe for use when the right side cannot be used.
Choice B reason:
The right cephalic vein should be avoided in a patient with a right-sided mastectomy. Venipuncture on the same side as the mastectomy can increase the risk of complications, including lymphedema, which is a condition characterized by swelling due to lymph fluid accumulation. Therefore, the right cephalic vein is not an appropriate choice.
Choice C reason:
The left femoral artery is not a venipuncture site; it is an arterial site. Venipuncture refers to accessing a vein, not an artery, for blood collection. Additionally, arterial puncture is a more invasive procedure typically reserved for arterial blood gas analysis and is not performed for routine venipuncture.
Choice D reason:
Similar to choice B, the right basilic vein should be avoided for venipuncture in a patient who has had a right-sided mastectomy. The basilic vein is located on the inner side of the arm and using it could pose the same risks as using the right cephalic vein, including the potential for lymphedema.

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.
Correct Answer is B
Explanation
Choice A Reason:
Neutralization typically involves a chemical reaction to render a substance harmless or inert. In the context of a blood spill, neutralization would not be the primary concern, as the goal is to eliminate any potential infectious agents, not just to neutralize them.
Choice B Reason:
Disinfection is the process of cleaning an area or surface to destroy or prevent the growth of disease-causing microorganisms. When dealing with a blood spill, disinfection is crucial to ensure that any bloodborne pathogens present are effectively killed, reducing the risk of infection transmission.
Choice C Reason:
Containment refers to the measures taken to control or limit something, in this case, a spill. While containment is an important initial step in managing a spill to prevent it from spreading, it is not the process that refers to the actual cleaning and elimination of pathogens.
Choice D Reason:
Sterilization is a process that destroys all forms of microbial life, including spores, usually through the application of heat, chemicals, or irradiation. While sterilization is a more extreme level of decontamination than disinfection, it is not typically used for routine cleaning of blood spills on counters.
