A pregnant woman is in her third trimester.

She asks the nurse to explain how she can tell the true labor from false labor.

The nurse would explain that true labor contractions.

Choice A rationale

While hand hygiene is the most important factor in preventing the spread of germs to the baby, the primary reason for wearing gloves when handling a newborn immediately after birth is not to protect the baby from the nurse. Apgar scores and initial assessments are often performed while the infant is still covered in amniotic fluid and blood. Standard precautions are designed to protect healthcare workers from potential exposure to maternal pathogens found in these body fluids.

Choice B rationale

Standard precautions require the use of gloves when there is potential contact with blood, body fluids, or non-intact skin. Newborns are born covered in amniotic fluid, maternal blood, and vernix caseosa, all of which are considered potentially infectious materials. The nurse wears gloves to prevent the transmission of bloodborne pathogens, such as HIV, Hepatitis B, or Hepatitis C, from the maternal fluids on the infant's skin to the nurse's own hands before the first bath.

Choice C rationale

The Apgar scoring system is a clinical tool used to evaluate the newborn's physical condition at 1 and 5 minutes after birth. It assesses heart rate, respiratory effort, muscle tone, reflex irritability, and color. While the nurse may be wearing gloves while performing this assessment due to the presence of body fluids, the Apgar protocol itself does not dictate the use of personal protective equipment. The use of gloves is a broader infection control policy.

Choice D rationale

Wearing gloves is a clinical safety requirement and does not serve as a symbolic indicator of who has primary responsibility for the infant's care. Both the primary nurse and the parents have responsibilities, but the nurse uses gloves as part of a professional safety standard. Communicating the purpose of gloves helps the father understand that the practice is a routine safety measure for the staff rather than an indication of a health problem with his baby.

Choice B rationale

Newborns are born with a sterile gastrointestinal tract, meaning they lack the normal flora or bacteria necessary to synthesize vitamin K. Vitamin K is a fat-soluble vitamin essential for the synthesis of clotting factors II, VII, IX, and X in the liver. Since it takes several days for the infant's gut to become colonized through feeding, the injection is administered to prevent Vitamin K Deficiency Bleeding, a potentially fatal hemorrhagic condition.

Choice C rationale

Vitamin K has no direct physiological role in the production or metabolism of bilirubin in the liver. Bilirubin levels are managed through the breakdown of red blood cells and hepatic conjugation processes. While the liver is the site where vitamin K facilitates the production of coagulation factors, its administration is strictly for the prevention of hemorrhage and has no effect on the development of neonatal jaundice or the excretion of heme byproducts.

Choice D rationale

It is inaccurate to state that infants are deficient in vitamin K for an entire year. Once the newborn begins regular feedings, bacteria such as Escherichia coli begin to colonize the intestines and produce vitamin K naturally. This physiological process usually establishes adequate levels within the first week of life. The prophylactic injection given at birth provides the necessary levels to protect the infant during those critical first few days before natural production begins.
