A client is 6 weeks pregnant. She had a previous spontaneous abortion at 13 weeks of gestation and a pregnancy that ended at 38 weeks with the birth of a girl.
What does the nurse determine is her gravida and para?

Choice A rationale

Erosive arthritis is not typically associated with Systemic Lupus Erythematosus (SLE). While many SLE patients experience joint pain and swelling known as lupus arthritis, it is characteristically non-erosive and non-deforming. This distinguishes it from rheumatoid arthritis, where the inflammatory process actively destroys bone and cartilage. In SLE, the joint involvement is usually transient and does not show the classic "punched-out" erosions on radiographic imaging, making this finding an unlikely or invalid sign for a typical SLE diagnosis.

Choice B rationale

Pericarditis is a well-recognized manifestation of Systemic Lupus Erythematosus and is the most common cardiac complication of the disease. It involves inflammation of the pericardium, the sac surrounding the heart, which can cause chest pain and a pericardial friction rub. Since SLE is a multisystem inflammatory disease that frequently targets serous membranes, the presence of pericarditis is highly consistent with the pathology of SLE and would be a valid sign found in a patient's medical record.

Choice C rationale

Photosensitivity is a classic and highly valid sign of Systemic Lupus Erythematosus. Approximately 60 to 90 percent of patients with SLE experience an abnormal reaction to ultraviolet (UV) light, which can trigger both skin rashes and systemic disease flares. UV exposure causes skin cell damage and the release of nuclear antigens that react with circulating antibodies, worsening the autoimmune response. Therefore, a history of skin reactions to sunlight is a key diagnostic criterion for the condition.

Choice D rationale

A red, macular facial rash, commonly known as the malar or "butterfly" rash, is the most iconic physical sign of Systemic Lupus Erythematosus. This rash typically spreads across the bridge of the nose and the cheeks while sparing the nasolabial folds. It is a valid clinical finding that appears in a large percentage of patients, particularly during periods of disease activity. Its presence is one of the primary physical markers used by clinicians to identify and monitor SLE.

Choice A rationale

Artificial rupture of membranes, also known as an amniotomy, is a procedure where the amniotic sac is intentionally punctured to induce or augment labor. While it involves a physical intervention, it does not typically involve the type of placental or uterine wall trauma that leads to significant fetomaternal hemorrhage. Therefore, it is not a standard, primary indication for the administration of RhoGAM unless it was accompanied by other complications that resulted in the mixing of fetal and maternal blood.

Choice B rationale

Placenta abruption involves the premature separation of the placenta from the uterine wall, which often causes significant bleeding at the site of attachment. This event creates a high risk for fetomaternal hemorrhage, where Rh positive fetal red blood cells enter the Rh negative mother's circulation. To prevent the mother from developing antibodies against the D antigen, RhoGAM must be administered. This prevents hemolytic disease of the newborn in future pregnancies by providing passive immunity that clears fetal cells.

Choice C rationale

The application of a fetal scalp electrode is a method of internal fetal monitoring that involves attaching a small spiral electrode to the fetal presenting part. While this causes a minor puncture in the fetal skin, it does not usually result in a significant enough breach of the placental barrier to cause maternal sensitization. Consequently, this procedure is generally not considered an indication for RhoGAM administration, as the risk of maternal exposure to fetal blood during this specific process is extremely low.

Choice D rationale

Amniocentesis is a diagnostic procedure where a needle is inserted through the maternal abdomen and into the uterine cavity to withdraw amniotic fluid. Because the needle must pass through the uterine environment and potentially near the placenta, there is a distinct risk of causing a small amount of fetal blood to enter the maternal bloodstream. In Rh negative mothers, this potential exposure necessitates the administration of RhoGAM to prevent the formation of permanent anti-D antibodies that could harm future fetuses.

Choice E rationale

Chorionic villus sampling is a prenatal test performed in early pregnancy that involves taking a sample of placental tissue for genetic testing. Similar to amniocentesis, this invasive procedure carries a significant risk of fetomaternal hemorrhage because it directly disrupts the placental structure. Any time there is a risk of fetal cells entering maternal circulation in an Rh negative individual, RhoGAM is required to provide immunoprophylaxis and protect against the development of Rh isoimmunization, ensuring the safety of subsequent pregnancies
