What could be the primary reason for early decelerations in the fetal heart rate (FHR) pattern?
Spontaneous rupture of membranes.
Uteroplacental insufficiency.
Altered fetal cerebral blood flow.
Umbilical cord compression.
The Correct Answer is A
Choice A rationale
Early decelerations in the fetal heart rate (FHR) are caused by compression of the fetus’s head during a uterine contraction. This often happens during later stages of labor as the baby is descending through the birth canal. They may also occur during early labor if the baby is premature or in a breech position. This causes the uterus to squeeze the head during contractions.
Choice B rationale
Uteroplacental insufficiency is a condition where the placenta does not provide enough oxygen and nutrients to the fetus. This condition is typically associated with late decelerations in the FHR, not early decelerations.
Choice C rationale
Altered fetal cerebral blood flow is not typically associated with early decelerations in the FHR34.
Choice D rationale
Umbilical cord compression is typically associated with variable decelerations in the FHR, not early decelerations.

Correct Answer is B
Explanation
Choice A rationale
Encouraging the client to perform Kegel exercises can help strengthen pelvic floor muscles, but it does not address the immediate problem of a displaced and boggy uterus.
Choice B rationale
Assisting the client to the bathroom to void is the correct action. A full bladder can displace the uterus and prevent it from contracting properly, which can lead to uterine atony and increased risk of postpartum hemorrhage.
Choice C rationale
Asking the client to rate her pain is important, but it does not address the immediate problem of a displaced and boggy uterus.
Choice D rationale
Encouraging the client to move to the left lateral position can improve venous return and cardiac output, but it does not address the immediate problem of a displaced and boggy uterus
Correct Answer is B
Explanation
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.
