A nurse is administering a unit of RBC 350 mL over 3 hr to a client who has anemia. The nurse should set the IV pump to deliver how many mL/hr?

(Round the answer to the nearest whole number)

Choice A reason: Painless red vaginal bleeding is the most characteristic finding of placenta previa, which is a condition where the placenta covers the cervical opening and can cause bleeding in the third trimester. Painless red vaginal bleeding occurs because the placenta is detached from the lower uterine segment as the cervix dilates or effaces, and the blood vessels are torn. The bleeding can be mild or severe, and it can recur or persist until delivery.

Choice B reason: Intermittent abdominal pain following passage of bloody mucus is not a finding that supports placenta previa, but rather a finding that suggests normal labor or preterm labor. Intermittent abdominal pain is caused by uterine contractions, which can be regular or irregular, and can increase in frequency, duration, and intensity. Bloody mucus is the mucus plug that is expelled from the cervix as it dilates or effaces, and it can be tinged with blood or streaked with blood.

Choice C reason: Increasing abdominal pain with a nonrelaxed uterus is not a finding that supports placenta previa, but rather a finding that indicates abruptio placentae, which is a premature separation of the placenta from the uterine wall. Increasing abdominal pain is caused by the bleeding and the hematoma formation behind the placenta, which can compress the uterine muscle and the nerve endings. Nonrelaxed uterus is a sign of uterine hypertonicity, which can reduce the blood flow and the oxygen delivery to the fetus.

Choice D reason: Abdominal pain with scant red vaginal bleeding is not a finding that supports placenta previa, but rather a finding that suggests ectopic pregnancy, which is a condition where the fertilized ovum implants outside the uterine cavity, usually in the fallopian tube. Abdominal pain is caused by the rupture of the tube and the bleeding into the peritoneal cavity, which can irritate the diaphragm and the abdominal wall. Scant red vaginal bleeding is a sign of implantation bleeding, which can occur when the fertilized ovum attaches to the tube wall.

Choice A reason: Administering oxygen via nasal cannula is not a necessary intervention for the client, unless she has signs of hypoxia, such as dyspnea, tachypnea, or cyanosis. Oxygen administration is not routinely indicated for clients with inevitable abortion.

Choice B reason: Offering option to view products of conception is an appropriate intervention for the client, because it can help her cope with the loss of pregnancy and facilitate the grieving process. The nurse should respect the client's decision and provide emotional support.

Choice C reason: Instructing the client to increase potassium-rich foods in the diet is not a relevant intervention for the client, unless she has signs of hypokalemia, such as muscle weakness, cramps, or arrhythmias. Potassium intake is not related to the cause or prevention of inevitable abortion.

Choice D reason: Maintaining the client in a Trendelenburg position is not a recommended intervention for the client, because it can increase the risk of aspiration, respiratory compromise, and venous congestion. Trendelenburg position is not effective in preventing or treating inevitable abortion.
