As a woman enters the second stage of labor, her membranes spontaneously rupture. What action should the nurse take?

Check fetal heart rate

instruct her to bare down with the next contraction

Place her legs in stirrups

Test a sample of the amniotic fluid for meconium

Answer and Explanation

The Correct Answer is A

A) Check fetal heart rate:
The first priority when a woman's membranes spontaneously rupture is to assess fetal well-being. The nurse should immediately check the fetal heart rate (FHR) after the rupture of membranes to evaluate for any signs of fetal distress. If there are any concerns regarding the FHR, further interventions may be needed, such as adjusting the maternal position or preparing for a possible emergent delivery. Monitoring the FHR will help guide subsequent decisions regarding care.

B) Instruct her to bear down with the next contraction:
While the second stage of labor involves pushing, it is important to wait for the appropriate signs of readiness before instructing the mother to bear down. The nurse should ensure the cervix is fully dilated and that fetal descent is progressing appropriately. Rushing into pushing too early or without proper readiness can lead to maternal and fetal complications.

C) Place her legs in stirrups:
Placing the mother’s legs in stirrups is typically done once she is in the active phase of pushing (typically when the cervix is fully dilated and fetal descent is ready). It is not the first priority immediately after the membranes rupture. The nurse should first assess the fetal heart rate and ensure the woman is comfortable and ready to push before assuming the lithotomy position or placing her legs in stirrups.

D) Test a sample of the amniotic fluid for meconium:
Testing the amniotic fluid for meconium should be done if there is concern that the amniotic fluid may be stained, as meconium in the amniotic fluid can be a sign of fetal distress. However, the first action after the membranes rupture is to check the fetal heart rate. If the FHR is normal, further actions, like testing the fluid, may follow, but the priority remains assessing fetal well-being.

Correct Answer is C

Explanation

A) Dry and stimulate newborn with towel:
Drying and stimulating the newborn immediately after birth is a standard practice to prevent heat loss and promote early bonding. This action helps to prevent heat loss through evaporation and stimulates the newborn to breathe. It is an appropriate intervention to reduce the risk of hypothermia, not increase it.

B) Place a hat on the newborn's head:
Placing a hat on the newborn’s head is an appropriate and helpful intervention. Since a significant amount of heat is lost through the head, especially in newborns who have a larger surface area relative to their body mass, keeping the head covered with a hat helps to retain warmth and reduce the risk of hypothermia. This would not place the newborn at risk for hypothermia.

C) Maintain the delivery room temperature at 20° C (68° F):
A delivery room temperature of 20° C (68° F) is on the lower end of the recommended range for newborn care. Newborns are particularly susceptible to heat loss due to their high surface area-to-body weight ratio and immature thermoregulation system. A cooler environment like 20°C increases the risk of hypothermia, as the newborn will lose heat more quickly than it can generate on its own.

D) Place a blanket on top of maternal and newborn:
Placing a blanket over the mother and newborn is an appropriate intervention to prevent heat loss. This promotes warmth by reducing heat loss from the newborn's body surface to the cooler environment. This would not place the newborn at risk for hypothermia; instead, it helps to maintain body temperature.

Correct Answer is ["2"]

Explanation

Given:

Desired dose: Ampicillin 0.5 g PO

Available concentration: Ampicillin capsules 250 mg each

To find:

Number of capsules to administer for a single dose

Step 1: Convert desired dose to milligrams

We know that 1 gram (g) is equal to 1000 milligrams (mg). Therefore, to convert the desired dose from grams to milligrams, we multiply by 1000:

Desired dose (mg) = Desired dose (g) x 1000

Desired dose (mg) = 0.5 g x 1000 = 500 mg

Step 2: Calculate the number of capsules

To find the number of capsules, we divide the desired dose by the strength of each capsule:

Number of capsules = Desired dose / Capsule strength

Number of capsules = 500 mg / 250 mg/capsule = 2 capsules
