Which of the following areas should a phlebotomist use for a capillary collection from a 2-month-old infant?

Choice A reason:
Septicemia, also known as sepsis, is a serious bloodstream infection that can be life-threatening. It is not a disorder that is screened for at birth because it is not a congenital condition but rather an infection that can occur at any time when bacteria enter the bloodstream.

Choice B reason:
Bacteremia refers to the presence of bacteria in the bloodstream and, like septicemia, is not a congenital disorder. It is not typically screened for at birth as it is an acquired condition that can occur after exposure to bacteria.

Choice C reason:
Phenylketonuria (PKU) is a genetic disorder that results in an inability to metabolize the amino acid phenylalanine. Untreated, PKU can lead to intellectual disability, seizures, and other serious health problems. Newborn screening for PKU is required in every state in the U.S. because early detection and dietary treatment can prevent the severe consequences of the disorder.

Choice D reason:
Proteinuria is the presence of abnormal amounts of protein in the urine, which can be a sign of kidney disease. It is not a condition that is screened for at birth as part of the standard newborn screening panel.

Choice A reason:
Wearing gloves is an important step in preventing the spread of infection, but it is not the first step. Gloves provide a barrier between the phlebotomist's hands and the patient, which can help prevent the transmission of pathogens. However, gloves can still become contaminated, and if hand hygiene is not performed before donning gloves, pathogens can be transmitted when gloves are changed or removed.

Choice B reason:
Hand hygiene is widely recognized as the single most important practice in preventing the spread of infections. It is the first line of defense against the transmission of infectious agents. Washing hands with antimicrobial soap and water mechanically removes pathogens, and the antimicrobial agents in the soap can kill or inhibit the growth of microorganisms. This step is crucial before any patient contact, especially before invasive procedures like venipuncture.

Choice C reason:
Applying antiseptic to the puncture sites prior to venipuncture is a critical step in the prevention of infection at the site of the blood draw. This practice is essential for eliminating skin flora that could potentially enter the bloodstream during venipuncture. However, this is not the first step, as effective hand hygiene should precede any patient contact or procedure.

Choice D reason:
Decontaminating equipment before use is a necessary step to ensure that no infectious agents are transmitted via medical instruments. This includes cleaning and sterilizing equipment that comes into direct contact with the patient. While this is a vital part of infection control, it follows hand hygiene in the sequence of steps a phlebotomist should take.
