The nurse knows that a normal physiologic alteration of the circulatory system associated with thromboembolic events in pregnancy is:

Increased fibrinogen and decreased fibrinolysis.

Increased blood volume and increased cardiac output.

Decreased hematocrit and increased red blood cell level (RBC).

Decreased blood pressure and decreased hemoglobin.

Answer and Explanation

The Correct Answer is A

Choice A rationale

During pregnancy, there is an increase in fibrinogen and a decrease in fibrinolysis. These changes increase the risk of thromboembolic events, as they promote clot formation.

Choice B rationale

Increased blood volume and cardiac output are normal in pregnancy but do not directly increase the risk of thromboembolic events. They are adaptations to meet the increased metabolic demands.

Choice C rationale

Decreased hematocrit and increased RBC levels are typical in pregnancy but are related to the physiological dilution of blood, not thromboembolic risks.

Choice D rationale

Decreased blood pressure and hemoglobin are common in pregnancy due to increased blood volume but are not associated with increased thromboembolic risks. .

Correct Answer is C

Explanation

Choice A rationale

Syphilis can be treated with antibiotics, particularly penicillin. It is not true that there is no cure, and immunization against syphilis is not available. Proper treatment can prevent transmission to the fetus.

Choice B rationale

Changing cat litter, even with gloves, is not safe for pregnant women due to the risk of toxoplasmosis. Toxoplasmosis can cause serious complications in the fetus, and direct contact with cat feces should be avoided.

Choice C rationale

The best way to prevent CMV (cytomegalovirus) infection is through thorough and consistent hand hygiene. CMV is a common virus that can cause congenital infections, and hygiene practices are crucial for prevention.

Choice D rationale

RPR (Rapid Plasma Reagin) tests for syphilis, not rubella. A rubella vaccine would be needed if the mother is non-immune, but this would be administered post-delivery. The statement reflects a misunderstanding of the tests and vaccines.

A. Fetal nutrition and excretion are carried out by the placenta. B. Fetal respirations are carried out by the placenta. C. The placenta filters harmful substances from maternal blood. D. The placenta receives maternal blood from the uterine arteries.

Correct Answer is C

Explanation

Choice A rationale

Fetal nutrition and excretion are carried out by the placenta. This statement is correct. The placenta provides essential nutrients to the fetus and removes waste products from fetal blood.

Choice B rationale

Fetal respirations are carried out by the placenta. This statement is correct. The placenta facilitates gas exchange, providing oxygen to the fetus and removing carbon dioxide.

Choice C rationale

The placenta filters harmful substances from maternal blood. This statement is incorrect. While the placenta provides some barrier function, it does not filter all harmful substances from maternal blood, and certain drugs and toxins can cross the placental barrier and affect the fetus.

Choice D rationale

The placenta receives maternal blood from the uterine arteries. This statement is correct. Maternal blood flows to the placenta via the uterine arteries, supplying oxygen and nutrients to the fetal side of the placenta.
