A nurse is caring for a client having a biophysical profile.
The client asks what the test is for.
What should the nurse include in the response? (Select all that apply.)

Choice A rationale

A positive rubella serum antibody titer indicates immunity to rubella infection, which is protective during pregnancy. It is not an abnormal finding and does not require immediate reporting. Rubella immunity is important to prevent congenital rubella syndrome in the fetus, a severe condition causing defects such as deafness or cardiac anomalies.

Choice B rationale

Blood pressure of 144/94 mmHg is elevated and indicates gestational hypertension, which could progress to preeclampsia if not managed. Preeclampsia can lead to complications such as eclampsia, placental abruption, or maternal and fetal mortality. Normal blood pressure during pregnancy is less than 140/90 mmHg, making this finding critical to report.

Choice C rationale

Copious leukorrhea is a common physiological change in pregnancy due to increased estrogen levels and vascularity. It is usually benign and protective, preventing infections by maintaining a mildly acidic environment in the vagina. This finding does not warrant immediate concern unless associated with infection symptoms.

Choice D rationale

An O-negative blood type requires administration of Rh immunoglobulin to prevent Rh isoimmunization, but this is routinely managed in pregnancy. It is not an urgent issue unless there are concerns about fetomaternal hemorrhage or alloimmunization, which could harm an Rh-positive fetus.

Choice A rationale

Sunken fontanels are typically a sign of dehydration due to reduced intracranial pressure and are not specific to abusive head trauma. Abusive head trauma often results in elevated intracranial pressure or swelling, which would present differently. Therefore, this finding is unrelated to the mechanisms of abusive head trauma in a 2-month-old.

Choice B rationale

Retinal hemorrhages are strongly associated with abusive head trauma due to the shearing forces during shaking or impact, which rupture retinal blood vessels. This finding is a hallmark of non-accidental trauma in infants, as accidental injuries rarely cause this degree of internal ocular damage.

Choice C rationale

Large bruises on the body could indicate trauma but are not specific to abusive head trauma. Additionally, the pattern or location of bruises is significant for abuse, especially in non-mobile infants. However, bruises alone do not confirm head trauma specifically.

Choice D rationale

Lacerations, such as those on the forearm, might suggest trauma but lack specificity for abusive head trauma. Such injuries are more commonly associated with accidents or other forms of physical abuse that do not necessarily involve the head.
