Five days after a spontaneous vaginal delivery, a woman comes to the emergency room because she has a fever and persistent cramping. The nurse recognizes that the cause of these signs and symptoms may be:

Endometritis

Cystitis

Dehydration

Hypovolemic shock

Answer and Explanation

The Correct Answer is A

Endometritis. This is because the client's symptoms suggest that she has endometritis, which is an infection of the lining of the uterus. Endometritis is a common postpartum complication that can occur after vaginal or cesarean delivery. The client may also have foul-smelling vaginal discharge, chills, and fatigue.

Choice B is wrong because cystitis is an infection of the bladder that causes pain or burning during urination, not cramping.

Choice C is wrong because dehydration does not cause fever or persistent cramping.

Choice D is wrong because hypovolemic shock is a condition of low blood volume that causes low blood pressure, rapid pulse, and pale skin, not fever or cramping.

Correct Answer is C

Explanation

ask the client to empty her bladder. A full bladder can cause the uterus to be displaced and lead to excessive bleeding. The moderate lochia rubra, normal temperature, soft breasts, firm fundus, slightly deviated to the right, pulse rate of 88/min, and respiratory rate of 18/min are all normal findings.

Choice A is not correct because the client's milk will come in regardless of nursing frequency.

Choice B is not correct because the client's temperature is within normal limits.

Choice D is not correct because there is no indication of an increase in IV fluids.

A. The ductus arteriosus expands to allow more blood to enter the lungs B. The foramen ovale closes, preventing blood exchange from right to left in the heart C. The umbilical vein that carried oxygenated blood in utero becomes the ascending aorta entering the right atrium D. The ductus venosus shunts oxygenated aortic blood to the lungs.

Correct Answer is B

Explanation

The foramen ovale closes, preventing blood exchange from right to left in the heart. This is because the foramen ovale is a fetal shunt that allows blood to bypass the lungs and flow from the right atrium to the left atrium. After birth, when the baby starts to breathe air, the lungs expand and the pulmonary resistance decreases. This causes an increase in blood flow and pressure in the left atrium, which pushes the foramen ovale closed. This prevents blood from mixing between the right and left sides of the heart and allows oxygenated blood to circulate to the body¹².

Choice A is not correct because the ductus arteriosus does not expand to allow more blood to enter the lungs. The ductus arteriosus is another fetal shunt that

connects the pulmonary artery to the aorta. It allows blood to bypass the lungs and flow from the right ventricle to the aorta. After birth, when the baby starts to breathe air, the oxygen concentration in the blood increases and causes the ductus arteriosus to constrict and close. This increases blood flow to the lungs and decreases blood flow to the aorta.

Choice C is not correct because the umbilical vein that carried oxygenated blood in utero does not become the ascending aorta entering the right atrium. The umbilical vein is a fetal vessel that carries oxygenated blood from the placenta to the fetus. It connects to either the portal vein or the ductus venosus, which then drains into the inferior vena cava. After birth, when the umbilical cord is clamped and cut, the umbilical vein collapses and becomes a fibrous cord called ligamentum teres hepatis.

Choice D is not correct because the ductus venosus does not shunt oxygenated aortic blood to the lungs. The ductus venosus is another fetal vessel that connects the umbilical vein to the inferior vena cava. It allows some of the oxygenated blood from the placenta to bypass the liver and enter directly into the systemic circulation. After birth, when the umbilical cord is clamped and cut, the ductus venosus closes and becomes a fibrous cord called ligamentum venosum.
