What is the estimated date of birth (EDB) for a client who is pregnant and whose last menstrual period began on July 27? (State the date in MMDD.
For example, July 27 is 0727)

Choice A rationale
Placing a newborn under a radiant heat warmer after birth does not directly prevent basal metabolic rate reduction. The primary function of a radiant heat warmer is to maintain the newborn’s body temperature and prevent hypothermia.
Choice B rationale
While brown fat production is a mechanism used by newborns to generate heat, placing a newborn under a radiant heat warmer does not stimulate brown fat production.
Choice C rationale
The primary purpose of placing a newborn under a radiant heat warmer after birth is to maintain the newborn’s body temperature. Newborns can lose heat rapidly, as they have a

large surface area compared to their body weight. The radiant heat warmer provides a controlled environment that helps maintain the newborn’s body temperature.
Choice D rationale
Preventing hypothermia is a key reason for placing a newborn under a radiant heat warmer. However, the direct purpose of the warmer is to maintain the newborn’s body temperature.

Choice A rationale
While the hepatitis B vaccine is an important part of preventing hepatitis B infection, it is not typically given on a monthly basis until the newborn tests negative for the hepatitis B surface antigen. Instead, the vaccine is usually given in a series of three to four doses over a six-month period.
Choice B rationale
For newborns who test positive for the hepatitis B surface antigen, the current recommendation is to administer both the hepatitis B immune globulin (HBIG) and the

hepatitis B vaccine within 12 hours of birth. The HBIG provides immediate, short-term protection against the virus, while the vaccine stimulates the newborn’s immune system to provide long-term protection.
Choice C rationale
While the hepatitis B immune globulin (HBIG) and the hepatitis B vaccine are both important for preventing hepatitis B infection in newborns, they are not typically administered in the manner described in this choice. The HBIG is usually given once, within 12 hours of birth, while the vaccine is given in a series of three to four doses over a six-month period.
Choice D rationale
The hepatitis B vaccine is typically given within 24 hours of birth, but it is not followed by doses of the hepatitis B immune globulin (HBIG) every 12 hours for three days. Instead, a single dose of HBIG is usually given within 12 hours of birth, along with the first dose of the vaccine.
