A nurse is assessing a client who has a grade 2 placental abruption.
Which of the following findings should the nurse expect?

Choice A rationale

Instructing the client to be NPO (nil per os), or nothing by mouth, is not typically required before an amniocentesis procedure. The client can usually eat and drink normally. Fasting is more commonly associated with procedures involving general anesthesia or those where there is a risk of aspiration, neither of which is routine for an amniocentesis. Clients may be asked to empty their bladder before the procedure to avoid puncturing it.

Choice B rationale

For an Rh-negative client undergoing an amniocentesis, there is a risk of fetomaternal hemorrhage during the procedure, which can lead to the mother's immune system producing Rh antibodies that attack the fetus's red blood cells in the current or future pregnancies. Therefore, administering Rh(D) immune globulin (RhoGAM) after the procedure is essential to prevent Rh sensitization. The standard dose is administered within 72 hours of the procedure.

Choice C rationale

Positioning the client in a left lateral position is typically used to promote optimal uteroplacental perfusion or during the second stage of labor. For an amniocentesis, the client is usually positioned in a supine position with a wedge placed under the right hip to slightly tilt the uterus and prevent vena cava compression, providing the provider with a clear anatomical view for ultrasound guidance.

Choice D rationale

The insertion site on the client's abdomen is cleaned with an antiseptic solution, such as povidone-iodine or chlorhexidine, to reduce the risk of introducing bacteria into the sterile field or uterus. Irrigating the site with sterile water is an inappropriate action for skin preparation as it is not a primary antiseptic and may interfere with the effectiveness of the chosen antiseptic solution.

Choice A rationale

Misoprostol is a prostaglandin analog used to prevent or treat postpartum hemorrhage by inducing uterine contractions, but it is not the primary intervention for preeclampsia without severe features, which focuses on blood pressure control and seizure prophylaxis.

Choice B rationale

Administering an IV bolus of lactated Ringer's is generally contraindicated in preeclampsia because it can increase the risk of pulmonary edema due to generalized fluid retention and increased capillary permeability characteristic of the disorder. Fluid management should be conservative.

Choice C rationale

Clonus, which is the presence of rhythmic, involuntary muscle contractions, is a sign of hyperreflexia and central nervous system irritability. It indicates worsening preeclampsia and the potential progression to eclampsia (seizures), necessitating close neurological assessment for timely intervention.

Choice D rationale

Restricting daily oral fluid intake can lead to dehydration and is not a standard or necessary practice for preeclampsia management without severe features, unless there is evidence of pulmonary edema or acute kidney injury. The focus is on careful fluid balance, not routine restriction.
