A nurse is admitting a term newborn following a cesarean birth. The nurse observes that the newborn's skin is slightly yellow right after birth. This finding indicates the newborn is experiencing a complication related to which of the following?

Physiological jaundice

Maternal cocaine abuse

Maternal/newborn blood group incompatibility

Absence of vitamin K

Answer and Explanation

The Correct Answer is C

Choice A reason: Physiological jaundice is not the correct answer, as it is a normal and benign condition that occurs in about 60% of term newborns, and usually appears after the first 24 hours of life. Physiological jaundice is caused by the breakdown of fetal hemoglobin and the immature liver function, and resolves within a few days.

Choice B reason: Maternal cocaine abuse is not the correct answer, as it is a maternal risk factor that can cause various complications in the newborn, such as low birth weight, prematurity, intrauterine growth restriction, or congenital anomalies. Maternal cocaine abuse does not cause jaundice in the newborn, unless it leads to hepatic or renal dysfunction.

Choice C reason: Maternal/newborn blood group incompatibility is the correct answer, as it is a maternal-fetal condition that can cause hemolytic disease of the newborn, which is a severe form of jaundice that can appear within the first 24 hours of life. Maternal/newborn blood group incompatibility occurs when the mother's blood type is Rh negative and the newborn's blood type is Rh positive, or when the mother's blood type is O and the newborn's blood type is A or B. The maternal antibodies cross the placenta and attack the newborn's red blood cells, causing hemolysis, anemia, and hyperbilirubinemia.

Choice D reason: Absence of vitamin K is not the correct answer, as it is a nutritional deficiency that can cause hemorrhagic disease of the newborn, which is a bleeding disorder that can occur within the first week of life. Absence of vitamin K is due to the lack of intestinal flora and the low vitamin K content in breast milk, and can cause bleeding in the skin, mucous membranes, or internal organs. Absence of vitamin K does not cause jaundice in the newborn, unless it leads to hepatic or biliary dysfunction.

Correct Answer is B

Explanation

Choice A reason: Increased subcutaneous fat is not a typical finding in a newborn who was born at 42.5 weeks of gestation, because it is more characteristic of a term or preterm newborn. A postterm newborn tends to have less subcutaneous fat, and may appear thin and wasted.

Choice B reason: Dry, cracked skin is a common finding in a newborn who was born at 42.5 weeks of gestation, because the skin has been exposed to the amniotic fluid for a prolonged period. The skin may also appear peeling, wrinkled, or leathery.

Choice C reason: Scant scalp hair is not a usual finding in a newborn who was born at 42.5 weeks of gestation, because it is more characteristic of a preterm newborn. A postterm newborn tends to have more scalp hair, and may also have long nails and abundant lanugo.

Choice D reason: Copious vernix is not a specific finding in a newborn who was born at 42.5 weeks of gestation, because it is more characteristic of a term or preterm newborn. A postterm newborn tends to have little or no vernix, which is a white, cheesy substance that protects the skin in utero.

A. Calcium carbonate B. Potassium chloride C. Ferrous sulfate D. Calcium gluconate

Correct Answer is D

Explanation

Choice A reason: Calcium carbonate is not the compound that the nurse should have readily available, as it is an antacid that neutralizes stomach acid and relieves heartburn. Calcium carbonate is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.

Choice B reason: Potassium chloride is not the compound that the nurse should have readily available, as it is an electrolyte supplement that replenishes potassium levels and prevents hypokalemia. Potassium chloride is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.

Choice C reason: Ferrous sulfate is not the compound that the nurse should have readily available, as it is an iron supplement that prevents or treats iron deficiency anemia. Ferrous sulfate is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.

Choice D reason: Calcium gluconate is the compound that the nurse should have readily available, as it is an antidote that reverses the effects of magnesium sulfate and restores calcium levels and neuromuscular function. Calcium gluconate is used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.
