A nurse is caring for a laboring client and notes that the fetal heart rate begins to decelerate after the contraction has started. The lowest point of deceleration occurs after the peak of the contraction. What is the priority nursing action?

Correct Answer: B

Rationale: Late decelerations are caused by uteroplacental insufficiency, indicating that the fetus is not receiving adequate oxygen during contractions. This is an emergency that requires prompt intervention. Changing the client's position helps to improve placental blood flow, which can reduce the stress on the fetus. If the decelerations continue, further interventions, including oxygen administration and notifying the provider, may be necessary.

Correct Answer: B

Rationale: Naegele's rule is a standard way of calculating an estimated delivery date (EDD). It involves subtracting three months from the first day of the last menstrual period (LMP), adding seven days, and then adding one year. In this case, subtracting three months from May 4th, 2013, gives February 4th. Adding seven days results in a due date of February 11th, 2014.

Correct Answer: A

Rationale: Meperidine is an opioid analgesic that can cross the placenta and cause respiratory depression in the newborn. Naloxone is an opioid antagonist that is administered to reverse the effects of opioids. It is critical to have Naloxone available when opioids are administered during labor, especially close to delivery.

Correct Answer: C

Rationale: The correct course of action after missing oral contraceptive pills depends on how many pills are missed. If three pills are missed, the client should not 'double up' but rather follow the manufacturer's instructions and use an alternative form of contraception until the next cycle. Taking too many pills at once increases the risk of side effects without restoring contraceptive protection.
