A nurse is reinforcing teaching with a client who is 15 weeks pregnant about to undergo amniocentesis. This test can identify which traits or problems? Select all that apply.

Choice A rationale:

Tachycardia, or a fast heart rate, is not a common finding in severe preeclampsia. While some women with preeclampsia may experience a slight increase in heart rate, it is not typically a significant or defining feature of the condition. In fact, some women with severe preeclampsia may even experience a slightly decreased heart rate due to increased vagal tone.

Choice B rationale:
Hypotension, or low blood pressure, is also not a typical finding in severe preeclampsia. Blood pressure is often elevated in preeclampsia, and it is one of the key diagnostic criteria. Hypotension would be a concerning finding in a woman with preeclampsia, as it could indicate a serious complication such as placental abruption or HELLP syndrome (Hemolysis, Elevated Liver enzymes, and Low Platelet count).

Choice C rationale:
Polyuria, or excessive urination, is not a characteristic finding of severe preeclampsia. In fact, many women with preeclampsia experience oliguria, or decreased urine output, due to decreased kidney function. This is because preeclampsia can cause damage to the blood vessels in the kidneys, impairing their ability to filter blood and produce urine.

Choice D rationale:
Headache is a common and often severe symptom of severe preeclampsia. It is thought to be caused by increased pressure within the brain due to swelling and vasoconstriction of the blood vessels. Headaches in preeclampsia can be very intense and may be accompanied by other symptoms such as blurred vision, nausea, and vomiting. They are often a sign that the preeclampsia is worsening and that delivery may be necessary.

Choice A rationale:
Large amount of bright red vaginal bleeding is the cardinal sign of placenta previa. This is because the placenta is abnormally positioned low in the uterus, covering the cervix partially or completely. When the cervix starts to dilate in preparation for labor, it can detach from the uterine wall, leading to significant bleeding. The blood is typically bright red, indicating fresh bleeding, and can be painless.
Severity of bleeding: The amount of bleeding can vary from spotting to massive hemorrhage, and it may start suddenly or gradually. Even a small amount of bleeding can be a sign of placenta previa and should not be ignored.
Risks of hemorrhage: Prompt recognition and management of bleeding are crucial to prevent potentially life-threatening hemorrhage for both the mother and the fetus.

Choice B rationale:
Severe pain with no bleeding is not a typical presentation of placenta previa. While some women with placenta previa may experience mild abdominal pain or cramping, severe pain without bleeding is more suggestive of placental abruption, a condition where the placenta prematurely separates from the uterine wall.

Choice C rationale:
High-grade fever is not a direct symptom of placenta previa. However, if a woman with placenta previa develops a fever, it could indicate an infection, which can further complicate the condition and require immediate medical attention.

Choice D rationale:
Sudden sharp pain in the lower abdomen can be a sign of placental abruption but is not characteristic of placenta previa.
