Which statement below accurately describes the role of the ductus arteriosus?

The ductus arteriosus helps connect the umbilical artery to the inferior vena cava.

The ductus arteriosus only carries oxygenated blood from the left side of the heart to the right side.

The ductus arteriosus is found between the right and left atrium.

In fetal circulation, the pulmonary artery and aorta are connected via the ductus arteriosus.

Answer and Explanation

The Correct Answer is D

Choice A rationale

The ductus arteriosus does not connect the umbilical artery to the inferior vena cava. It connects the pulmonary artery to the aorta, bypassing the lungs in fetal circulation.

Choice B rationale

The ductus arteriosus carries deoxygenated blood from the right side of the heart to the aorta. It does not carry oxygenated blood from the left side of the heart.

Choice C rationale

The ductus arteriosus is not located between the right and left atrium. It is a blood vessel connecting the pulmonary artery to the aorta in fetal circulation.

Choice D rationale

In fetal circulation, the pulmonary artery and aorta are connected via the ductus arteriosus. This allows blood to bypass the fetal lungs, which are not yet functional.

Correct Answer is A

Explanation

Choice A rationale

Ballottement refers to the movement of the fetus felt by the provider when pushing on the cervix, causing the fetus to rise and then return to its original position. This is a probable sign of pregnancy.

Choice B rationale

Goodell’s sign refers to the softening of the cervix, which occurs due to increased vascularization during pregnancy. It is not related to the movement of the fetus felt by the provider.

Choice C rationale

Lightening refers to the sensation of the fetus moving down into the pelvis, usually occurring in the later stages of pregnancy. It is not related to the specific movement of the fetus felt by the provider.

Choice D rationale

Chadwick’s sign is the bluish discoloration of the cervix, vagina, and labia due to increased blood flow during pregnancy. It is not associated with the movement of the fetus felt by the provider.

A. "If your HIV testing comes back positive, your baby will be infected." B. "You may notice dark urine and a metallic taste caused by ceftriaxone." C. "After you take the azithromycin, do not consume any calcium-rich foods." D. "Let's discuss some options for notifying your sexual partners."

Correct Answer is D

Explanation

Choice B rationale: Ceftriaxone does not commonly cause dark urine or a metallic taste. These side effects are typically associated with other antibiotics, like metronidazole. The nurse should provide accurate information about medication side effects to maintain client trust.

Choice C rationale: Azithromycin absorption is not significantly affected by calcium intake. Unlike tetracyclines, which bind with calcium and reduce efficacy, azithromycin’s pharmacokinetics remain stable, ensuring the medication effectively treats the infection.

Choice D rationale: Discussing options for notifying sexual partners is essential for preventing the spread of sexually transmitted infections. It ensures that partners can seek testing and treatment, reducing the risk of re-infection and promoting overall community health.
