A nurse is caring for a client who is in labor. The nurse observes late decelerations of the fetal heart rate on the external fetal monitor. After placing the client in a side-lying position, which of the following actions should the nurse take?

A. Administer oxygen via a face mask: This is the correct answer. Administering oxygen helps improve oxygenation to the fetus and is a standard intervention for late decelerations.

B. Decrease the rate of IV fluids: Decreasing IV fluids is not typically the first intervention for late decelerations. The primary goal is to improve oxygenation to the fetus, and increasing or maintaining maternal blood volume is important.

C. Perform fetal scalp stimulation: Fetal scalp stimulation is not the first-line intervention for late decelerations. It is more commonly used for assessing fetal well-being and responsiveness during the labor process.

D. Elevate the client’s head: Elevation of the client's head is not the recommended position for addressing late decelerations. Placing the client in a side-lying position is more appropriate to relieve pressure on the vena cava.

A. This test determines if your baby is at risk for developing hypoglycemia after birth: The indirect Coombs' test is not related to assessing the risk of hypoglycemia in the baby. It specifically focuses on Rh sensitization.

B. The test will determine the amount of amniotic fluid around the fetus: The indirect Coombs' test does not assess the amount of amniotic fluid around the fetus. It is specifically aimed at detecting antibodies in the maternal blood.

C. The test studies blood flow in the fetus and placenta using ultrasound waves: This description is more indicative of a Doppler ultrasound or other tests that assess blood flow. The indirect Coombs' test is a blood test and does not involve ultrasound waves.

D. This test will detect the presence of Rh-positive antibodies in your blood

The indirect Coombs' test is performed during pregnancy to detect the presence of Rh antibodies in the maternal bloodstream. Rh antibodies can develop if an Rh-negative mother is carrying an Rh-positive baby, and there is a risk of hemolytic disease of the newborn (HDN) in subsequent pregnancies. The test helps identify if the mother has developed antibodies against Rh-positive blood, which could potentially affect the fetus.
