A nurse is caring for a client who is postpartum.
Which of the following findings is an indication for the nurse to administer Rho(D) immune globulin?
The client is Rh positive and the newborn is Rh positive
The client is Rh positive and the newborn is Rh negative
The client is Rh negative and the newborn is Rh negative
The client is Rh negative and the newborn is Rh positive
The Correct Answer is D
Choice A rationale:
Rh positive individuals already have the Rh factor on their red blood cells, so they do not need Rho(D) immune globulin to
prevent sensitization.
The newborn being Rh positive does not pose a risk to an Rh positive mother, as their blood types are compatible.
Choice B rationale:
Rh positive individuals cannot develop antibodies against the Rh factor, as it is already present on their own red blood cells.
The newborn's Rh negative status does not create a risk of sensitization for the mother, as there is no Rh factor to trigger an
immune response.
Choice C rationale:
If both the mother and the newborn are Rh negative, there is no risk of Rh incompatibility.
This is because neither individual has the Rh factor on their red blood cells, so there is no potential for sensitization.
Choice D rationale:
When an Rh negative mother carries an Rh positive fetus, there is a risk of Rh sensitization during pregnancy and delivery.
This occurs when fetal blood cells cross the placenta and enter the mother's bloodstream, exposing her immune system to the
Rh factor.
If the mother's immune system recognizes the Rh factor as foreign, it can produce antibodies against it.
These antibodies can cross the placenta in subsequent pregnancies and attack the red blood cells of Rh positive fetuses,
leading to hemolytic disease of the newborn (HDN).
Rho(D) immune globulin is a medication that can prevent Rh sensitization by binding to Rh positive fetal blood cells that have
entered the mother's bloodstream.
This prevents the mother's immune system from recognizing the Rh factor and producing antibodies.
Rho(D) immune globulin is typically given to Rh negative mothers within 72 hours of delivery of an Rh positive newborn, as well as after other events that could lead to Rh sensitization, such as miscarriage, abortion, or ectopic pregnancy.

Correct Answer is B
Explanation
Choice A rationale:
Placing the mother in Trendelenburg's position would not correct the uterine displacement. Trendelenburg's position involves
lowering the head of the bed and raising the feet, which can actually worsen uterine displacement by increasing pressure on
the uterus from the abdominal organs.
It is not indicated for uterine displacement and could potentially have adverse effects on the patient's hemodynamic status
and respiratory function.
Choice C rationale:
Notifying the physician is important, but it is not the first action the nurse should take.
The nurse should assess the patient and attempt to correct the displacement before notifying the physician.
Choice D rationale:
Recording the findings is important for documentation, but it is not an intervention that will correct the uterine displacement.
Choice B rationale:
Massaging the fundus is the correct action to take when a postpartum uterus is displaced.
The fundus is the top of the uterus, and massaging it can help to stimulate the uterine muscles to contract and return to their
normal position.
This is often effective in correcting mild to moderate uterine displacements.
Here are the steps involved in massaging the fundus:
Locate the fundus: The nurse should first locate the fundus by palpating the abdomen just below the umbilicus.
Apply gentle pressure: Once the fundus is located, the nurse should apply gentle pressure with the fingertips in a circular
motion.
Continue massaging: The massage should be continued for several minutes, or until the uterus is felt to be firm and in the
midline position.
Additional notes:
If the uterine displacement is severe, or if the patient is experiencing pain or bleeding, the nurse should notify the physician
immediately.
Other interventions that may be used to correct uterine displacement include:
Assisting the patient to empty her bladder
Straight catheterization
Administration of oxytocin to stimulate uterine contractions
Correct Answer is B
Explanation
Choice A rationale:
Oxygen administration is not indicated in this situation. The client's vital signs are stable, and there is no evidence of
respiratory distress.
Oxygen administration could potentially mask signs of postpartum hemorrhage, which is a serious complication.
It is important to assess the client's respiratory status closely, but oxygen should not be administered unless there is a clear
indication for it.
Choice B rationale:
Methylergonovine is a medication that is used to treat postpartum hemorrhage.
It works by contracting the uterus and reducing blood flow.
However, it is a potent medication that can have serious side effects, such as hypertension and seizures.
It is important to clarify the order with the provider before administering this medication.
The provider may want to assess the client further or consider other options before ordering methylergonovine.
Choice C rationale:
Inserting a urinary catheter is not necessary in this situation.
The client is not experiencing any urinary problems, and there is no evidence of bladder distention.
Catheterization can increase the risk of urinary tract infection, so it should only be performed when there is a clear indication
for it.
Choice D rationale:
Increasing the infusion rate of the IV fluid may be helpful in some cases of postpartum hemorrhage.
However, it is important to assess the client's fluid status before increasing the infusion rate.
Too much fluid can lead to pulmonary edema, which is a serious complication.
