## Question

An unsensitized Rh-negative client at 30 weeks of pregnancy is evaluated after a minor motor vehicle crash with abdominal impact. The client has no vaginal bleeding. Which prescription should the nurse anticipate?

## Option

1. Schedule only the routine antibody screen at the next prenatal visit
2. Delay prophylaxis until birth confirms that the newborn is Rh-positive
3. Arrange fetal administration of Rh immune globulin after ultrasonography
4. Administer prescribed Rh(D) immune globulin after the abdominal trauma **✔ Correct answer**

**Correct answer: 4**

## Explanation

Abdominal trauma can cause fetomaternal hemorrhage without vaginal bleeding. Give Rh(D) immune globulin to an unsensitized Rh-negative pregnant client after a sensitizing event to prevent anti-D antibody formation. The medication is administered to the pregnant client, not the fetus.

## In-depth explanation

Quick answer
Anticipate Rh(D) immune globulin for the unsensitized Rh-negative client after abdominal trauma.

Why this is correct
Fetal Rh-positive red cells can enter maternal circulation after trauma without visible bleeding. Rh immune globulin clears those cells before the maternal immune system forms antibodies that could affect this or a future pregnancy.

Easy analogy or mental picture
Rh immune globulin acts like a cleanup team that removes fetal Rh-positive cells before the maternal immune system records them as a target. The comparison does not mean it can reverse sensitization after anti-D antibodies already exist.

Memory hook
Rh-negative and not sensitized plus a bleeding-risk event means protect before antibodies form.

NCLEX decision rule
In an unsensitized Rh-negative pregnancy, anticipate Rh immune globulin after abdominal trauma or another potential fetomaternal hemorrhage unless the fetus is conclusively Rh-negative.

Why the other choices are wrong
Waiting for routine screening or delivery misses protection after the current sensitizing event. Rh immune globulin is given to the pregnant client rather than directly to the fetus.References
