A nurse is reviewing the laboratory results of a client with pre-eclampsia.

Which of the following findings would indicate a risk of disseminated intravascular coagulation (DIC)?

Decreased fibrinogen level.This indicates that the client has a risk of disseminated intravascular coagulation (DIC), which is a condition where the blood clots abnormally and causes bleeding in various organs.Fibrinogen is a protein that is essential for blood clotting, and a low level means that the clotting factors are being consumed faster than they can be produced.

Choice A is wrong because elevated platelet count is not a sign of DIC, but rather of normal pregnancy or other conditions that cause thrombocytosis.Platelets are blood cells that help form clots, and a high count means that there is an increased production or decreased destruction of platelets.

Choice C is wrong because increased prothrombin time (PT) is not a specific sign of DIC, but rather of any condition that affects the extrinsic pathway of coagulation.PT measures how long it takes for the blood to clot by adding tissue factor, which activates factor VII.A prolonged PT means that there is a deficiency or dysfunction of factor VII or other factors in the common pathway (X, V, II, I).

Choice D is wrong because reduced partial thromboplastin time (PTT) is not a sign of DIC, but rather of hypercoagulable states or antiphospholipid syndrome.PTT measures how long it takes for the blood to clot by adding phospholipids and an activator, which activate factor XII.A shortened PTT means that there is an increased activity or presence of factor XII or other factors in the intrinsic or common pathway.

To prevent blood pressure from exceeding 160/110 mmHg.The goal of pharmacological therapy for pre-eclampsia is to prevent severe hypertension that can lead to complications such as stroke, kidney failure, or placental abruption.

Choice A is wrong because maintaining blood pressure below 140/90 mmHg is the target for normal hypertension, not pre-eclampsia.

Choice B is wrong because reducing blood pressure by 25% within one hour is too rapid and can compromise blood flow to the placenta and the fetus.

Choice C is wrong because keeping diastolic blood pressure between 80 and 100 mmHg is not specific enough and does not account for the systolic blood pressure, which is also important.
