A. Hypocalcemia
Hypocalcemia is not the priority focus of care, as it is a low level of calcium in the blood that can cause muscle twitching, seizures, or cardiac arrhythmias. Hypocalcemia can affect newborns who have mothers with diabetes mellitus, but it is less common and less severe than hypoglycemia.
B. Hyperbilirubinemia
Hyperbilirubinemia is not the priority focus of care, as it is a high level of bilirubin in the blood that can cause jaundice, a yellowish discoloration of the skin and eyes. Hyperbilirubinemia can affect newborns who have macrosomia, but it is usually a benign and self-limiting condition that resolves within a few days.
C. Hypomagnesemia
Hypomagnesemia is not the priority focus of care, as it is a low level of magnesium in the blood that can cause tremors, tetany, or seizures. Hypomagnesemia can affect newborns who have mothers with diabetes mellitus, but it is rare and usually asymptomatic.
D. Hypoglycemia
Hypoglycemia is the priority focus of care, as it is a low level of glucose in the blood that can cause diaphoresis, jitteriness, lethargy, or apnea. Hypoglycemia can affect newborns who have macrosomia and mothers with diabetes mellitus, as they have increased insulin production and decreased glucose supply after birth. Hypoglycemia can lead to brain damage or death if not treated promptly.

Full Explanation
Choice A reason: Hypocalcemia is not the priority focus of care, as it is a low level of calcium in the blood that can cause muscle twitching, seizures, or cardiac arrhythmias. Hypocalcemia can affect newborns who have mothers with diabetes mellitus, but it is less common and less severe than hypoglycemia.
Choice B reason: Hyperbilirubinemia is not the priority focus of care, as it is a high level of bilirubin in the blood that can cause jaundice, a yellowish discoloration of the skin and eyes. Hyperbilirubinemia can affect newborns who have macrosomia, but it is usually a benign and self-limiting condition that resolves within a few days.
Choice C reason: Hypomagnesemia is not the priority focus of care, as it is a low level of magnesium in the blood that can cause tremors, tetany, or seizures. Hypomagnesemia can affect newborns who have mothers with diabetes mellitus, but it is rare and usually asymptomatic.
Choice D reason: Hypoglycemia is the priority focus of care, as it is a low level of glucose in the blood that can cause diaphoresis, jitteriness, lethargy, or apnea. Hypoglycemia can affect newborns who have macrosomia and mothers with diabetes mellitus, as they have increased insulin production and decreased glucose supply after birth. Hypoglycemia can lead to brain damage or death if not treated promptly.

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?
A. "It determines the presence of maternal antibodies in the newborn's blood."
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.
B. "It determines if kernicterus will occur in the newborn."
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.
C. "It detects Rh-positive antibodies in the mother's blood."
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.
D. "It detects Rh-negative antibodies in the newborn's blood."
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.

The labor of a pregnant woman with preeclampsia is going to be induced. Before initiating the oxytocin (Pitocin) infusion, the nurse reviews the woman's latest laboratory test findings, which reveal a platelet count of 90,000 mm3, an elevated aspartate aminotransferase (AST) level, and a falling hematocrit. The laboratory results are indicative of which condition?
A. Disseminated intravascular coagulation (DIC) syndrome
Disseminated intravascular coagulation (DIC) syndrome is not the correct answer, as it is a coagulation disorder that causes widespread clotting and bleeding in the body. DIC can occur as a complication of severe preeclampsia, but it is not indicated by the laboratory results. DIC would cause a low platelet count, but also a prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), and a low fibrinogen level.
B. Eclampsia
Eclampsia is not the correct answer, as it is a seizure disorder that occurs in clients with severe preeclampsia. Eclampsia can occur as a complication of severe preeclampsia, but it is not indicated by the laboratory results. Eclampsia would cause a high blood pressure, but also a proteinuria, edema, and hyperreflexia.
C. Hemolysis, elevated liver enzyme levels, and low platelet levels (HELLP) syndrome
Hemolysis, elevated liver enzyme levels, and low platelet levels (HELLP) syndrome is the correct answer, as it is a variant of severe preeclampsia that affects the blood and the liver. HELLP syndrome is indicated by the laboratory results, as it causes a low platelet count, an elevated AST level, and a falling hematocrit. HELLP syndrome would also cause a high blood pressure, a proteinuria, and a right upper quadrant pain.
D. Idiopathic thrombocytopenia
Idiopathic thrombocytopenia is not the correct answer, as it is an autoimmune disorder that causes the destruction of platelets by antibodies. Idiopathic thrombocytopenia can affect pregnant women, but it is not related to severe preeclampsia or the laboratory results. Idiopathic thrombocytopenia would cause a low platelet count, but not an elevated AST level or a falling hematocrit.

A nurse is preparing to administer an injection of Rh0 (D) immunoglobulin. The nurse should understand that the purpose of this injection is to prevent which of the following newborn complications?
A. Erythroblastosis fetalis
Erythroblastosis fetalis is the correct answer, as it is a hemolytic disease of the newborn that occurs when the mother is Rh-negative and the newborn is Rh-positive, and the maternal antibodies cross the placenta and destroy the newborn's red blood cells, causing anemia, jaundice, and edema. Rh0 (D) immunoglobulin is an injection that prevents the formation of Rh-positive antibodies in the mother, and reduces the risk of erythroblastosis fetalis in the current or subsequent pregnancies.
B. Hypobilirubinemia
Hypobilirubinemia is not the correct answer, as it is a low level of bilirubin in the blood that can cause pale skin, poor feeding, or lethargy. Hypobilirubinemia is not related to the Rh factor or the Rh0 (D) immunoglobulin injection, and it is not a common or serious complication in the newborn.
C. Biliary atresia
Biliary atresia is not the correct answer, as it is a congenital defect of the bile ducts that prevents the flow of bile from the liver to the intestine, causing jaundice, dark urine, and clay-colored stools. Biliary atresia is not related to the Rh factor or the Rh0 (D) immunoglobulin injection, and it is not a preventable complication in the newborn.
D. Transient clotting difficulties
Transient clotting difficulties is not the correct answer, as it is a bleeding disorder that occurs due to the deficiency of vitamin K, which is essential for the synthesis of clotting factors. Transient clotting difficulties is not related to the Rh factor or the Rh0 (D) immunoglobulin injection, and it is preventable by administering vitamin K to the newborn.
