A nurse is caring for a client who is 6 hr postpartum. The client is Rh-negative and her newborn is Rh-positive. The client asks why an indirect Coombs test was ordered by the provider. Which of the following is an appropriate response by the nurse?
"It determines the presence of maternal antibodies in the newborn's blood."
"It determines if kernicterus will occur in the newborn."
"It detects Rh-positive antibodies in the mother's blood."
"It detects Rh-negative antibodies in the newborn's blood."
The Correct Answer is C
Choice A reason: This statement is incorrect, as it describes the direct Coombs test, not the indirect Coombs test. The direct Coombs test is performed on the newborn's blood, and it detects the presence of maternal antibodies that have attached to the newborn's red blood cells. The direct Coombs test can help diagnose hemolytic disease of the newborn, which is a condition where the maternal antibodies destroy the newborn's red blood cells, causing anemia and jaundice.
Choice B reason: This statement is incorrect, as it is not the purpose of the indirect Coombs test, but rather a possible complication of hemolytic disease of the newborn. Kernicterus is a severe form of jaundice that occurs when the bilirubin level in the blood is very high, and it can cause brain damage, deafness, or death. Kernicterus can be prevented by treating the jaundice with phototherapy or exchange transfusion.
Choice C reason: This statement is correct, as it describes the indirect Coombs test, which is performed on the mother's blood, and it detects the presence of Rh-positive antibodies that have formed in response to the exposure to the Rh-positive blood of the newborn. The indirect Coombs test can help identify the risk of hemolytic disease of the newborn, and guide the administration of Rh immunoglobulin, which is a medication that prevents the formation of Rh-positive antibodies.
Choice D reason: This statement is incorrect, as it is not possible for the newborn to have Rh-negative antibodies, since the newborn has Rh-positive blood. Rh-negative antibodies are produced by Rh-negative individuals who have been exposed to Rh-positive blood, such as Rh-negative mothers who have Rh-positive newborns. Rh-negative antibodies can cross the placenta and attack the Rh-positive red blood cells of the newborn, causing hemolytic disease of the newborn.

Correct Answer is B
Explanation
The correct answer is B. No special treatment is necessary.
Choice A reason: Prone positioning is not typically recommended for a fractured clavicle in infants. It does not facilitate bone alignment in the case of clavicle fractures and is not part of standard care.
Choice B reason: This is the correct choice because clavicle fractures in newborns generally heal on their own without the need for special treatment. Parents may be instructed to pin the child’s sleeve to the front of their clothing to avoid moving the arm while it heals, but beyond gentle handling, no other special treatment is necessary. In most cases, clavicle fractures in newborns heal very quickly without any problems, and usually, no treatment is required.
Choice C reason: Immobilization and casting are not standard care for newborn clavicle fractures. These fractures typically heal without such interventions, and immobilization with a cast is not needed for these types of injuries in infants.
Choice D reason: While range-of-motion exercises might be beneficial later in the healing process, they are not the primary consideration immediately after the fracture occurs. The initial care plan focuses on gentle handling and comfort for the infant, not on exercises.
Correct Answer is B
Explanation
Choice A reason: Contractions occurring every 3 to 5 min are normal and expected in the active phase of the first stage of labor, which lasts from 4 to 8 cm of cervical dilation. The nurse does not need to report this finding to the provider.
Choice B reason: Each contraction lasting longer than 110 seconds is abnormal and concerning, as it can indicate uterine hyperstimulation, which can reduce the blood flow to the placenta and fetus, and cause fetal distress. The nurse should report this finding to the provider immediately and prepare for interventions, such as stopping oxytocin infusion, administering tocolytics, or performing an emergency cesarean section.
Choice C reason: Contractions are strong in intensity are also normal and expected in the active phase of the first stage of labor, as they facilitate the cervical dilation and effacement. The nurse does not need to report this finding to the provider.
Choice D reason: Client reports feeling contractions in lower back are common and not harmful, especially if the fetus is in the occiput posterior position, which causes the fetal head to press against the sacrum. The nurse does not need to report this finding to the provider, but can offer comfort measures, such as massage, counterpressure, heat, or position changes.
