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?

Erythroblastosis fetalis

Hypobilirubinemia

Biliary atresia

Transient clotting difficulties

Answer and Explanation

The Correct Answer is A

Choice A reason: 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.

Choice B reason: 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.

Choice C reason: 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.

Choice D reason: 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.

Correct Answer is B

Explanation

Choice A reason: Uterine enlargement greater than expected for gestational age is not a typical manifestation of ectopic pregnancy, because the embryo is implanted outside the uterus, usually in the fallopian tube. The uterus may be slightly enlarged due to hormonal changes, but not more than expected for the gestational age.

Choice B reason: Unilateral, cramp-like abdominal pain is a common manifestation of ectopic pregnancy, because the embryo grows and stretches the fallopian tube, causing inflammation and irritation. The pain may be mild or severe, depending on the size and location of the ectopic pregnancy, and may radiate to the shoulder or back.

Choice C reason: Severe nausea and vomiting is not a specific manifestation of ectopic pregnancy, because it can be caused by other conditions, such as hyperemesis gravidarum, gastroenteritis, or appendicitis. The client may have mild nausea and vomiting due to hormonal changes, but not more than usual for the gestational age.

Choice D reason: Large amount of vaginal bleeding is not a usual manifestation of ectopic pregnancy, because the bleeding is usually internal, into the abdominal cavity. The client may have spotting or light bleeding due to the detachment of the endometrium, but not heavy or profuse bleeding.

Correct Answer is ["117"]

Explanation

The correct answer is 117 mL/hr.

To calculate the IV rate, the nurse should use the following formula:

IV rate (mL/hr) = (Volume to be infused (mL) / Time of infusion (hr)) x Drop factor (gtt/mL)

In this case, the volume to be infused is 350 mL, the time of infusion is 3 hr, and the drop factor is 1 gtt/mL (assuming the IV pump is calibrated in mL/hr). Therefore, the formula becomes:

IV rate (mL/hr) = (350 mL / 3 hr) x 1 gtt/mL

IV rate (mL/hr) = 116.67 mL/hr

The nurse should round the answer to the nearest whole number, which is 117 mL/hr.
