A laboring client's membranes have just ruptured. What is the nurse's next action?

Assess the client's blood pressure.

Assess the fetal heart rate pattern.

Take the client's temperature.

Prepare for a c-section.

Answer and Explanation

The Correct Answer is B

Assess the fetal heart rate pattern.

Choice B rationale:

When a laboring client's membranes have just ruptured, the nurse's next action should be to assess the fetal heart rate pattern. Rupture of membranes can lead to changes in amniotic fluid, which can affect the fetal environment and potentially cause fetal distress. By assessing the fetal heart rate pattern, the nurse can determine if the baby is tolerating the labor process well or if there are signs of fetal compromise that require further intervention.

Choice A rationale:

While assessing the client's blood pressure (Choice A) is important during labor, it is not the immediate next action when the membranes have ruptured.

Choice C rationale:

Taking the client's temperature (Choice C) is also important, but it is not the priority action when the membranes have ruptured.

Choice D rationale:

Preparing for a c-section (Choice D) is not the initial action unless there are specific indications for an emergency cesarean section. Assessing the fetal heart rate is more critical at this stage.

Correct Answer is A

Explanation

Choice A rationale:

This is the correct choice. The American Academy of Pediatrics (AAP) recommends keeping children in a rear-facing car seat until they reach the age of 2 or until they reach the maximum weight and height allowed by the car seat's manufacturer. This is because rear- facing seats provide better support for a baby's head, neck, and spine during a crash, reducing the risk of injury.

Choice B rationale:

Placing the retainer clip over the upper part of the baby's abdomen is incorrect and potentially dangerous. The retainer clip should be positioned at armpit level to secure the harness straps properly.

Choice C rationale:

Placing the baby in the car seat at a 90-degree angle is not necessary. The car seat should be installed according to the manufacturer's instructions, and the angle will vary based on the specific car seat model.

Choice D rationale:

Placing the shoulder harness straps in the slots an inch above the baby's shoulders is incorrect. The straps should be positioned at or below the baby's shoulders for rear-facing car seats and at or above the shoulders for forward-facing seats.

A. The client's blood does not contain the Rh factor, so she produces anti-Rh antibodies that cross the placental barrier and cause hemolysis of red blood cells in newborns. B. The client's blood contains the Rh factor, and the newborn's does not, and antibodies that destroy red blood cells are formed in the fetus. C. The client has a history of receiving a transfusion with Rh-negative blood. D. The client's anti-A and anti-B antibodies cross the placenta and cause the destruction of the fetal red blood cells.

Correct Answer is A

Explanation

Choice A rationale:

Rh incompatibility occurs when an Rh-negative client is exposed to Rh-positive fetal blood, typically during a prior pregnancy or delivery. The client’s immune system produces anti-Rh antibodies that cross the placenta in subsequent pregnancies, attacking the Rh-positive red blood cells of the fetus. This hemolysis releases bilirubin, leading to hyperbilirubinemia in the newborn.

Choice B rationale:

Rh incompatibility only occurs when the client is Rh-negative and the fetus is Rh-positive. An Rh-positive client will not form antibodies against an Rh-negative fetus, as their immune system recognizes the Rh factor as normal.

Choice C rationale:

This choice is not related to the mechanism of Rh incompatibility. Receiving a transfusion with Rh-negative blood would not cause the mother's immune system to produce anti-Rh antibodies or lead to Rh incompatibility with her newborn.

Choice D rationale:

This choice describes the ABO blood group system, not the Rh factor. ABO incompatibility can occur when a mother with blood type O (producing anti-A and anti-B antibodies) has a newborn with blood type A, B, or AB, leading to hemolysis of the fetal red blood cells. However, the question specifically mentions Rh incompatibility, which involves the Rh factor, not the ABO system.
