The nurse is preparing to teach a prenatal class about fetal circulation. Which statements should be included in the teaching plan?

Correct Answer: A

Rationale: The ductus arteriosus bypasses fetal lungs. The umbilical vein carries oxygenated blood, and arteries carry deoxygenated blood to the placenta.

Correct Answer: B

Rationale: The Four Cs (Concerns, Causes, Comfort, and Collaboration) focus on understanding the patient's perspective and concerns.

Correct Answer: D

Rationale: The implant provides long-term contraception for 3 years, so the patient should understand it is a long-term method. Choice A is correct, and the patient must be aware of this. Choice B is correct, as the procedure involves a minor surgical process, and the patient will need someone to drive them home. Choice C is correct because irregular bleeding is a common side effect of the implant. Choice D is incorrect, as the implant does not provide STI protection.

Correct Answer: D

Rationale: Blurred vision is a potential prenatal complication during the third trimester of pregnancy and can be a sign of conditions such as preeclampsia or gestational diabetes. It is important for the nurse to further assess this finding and consult with the healthcare provider to ensure appropriate management and monitoring of the client's condition. Periodic tingling of fingers, absence of clonus, and leg cramps are common discomforts during pregnancy and do not typically indicate a prenatal complication.

Correct Answer: A

Rationale: The ductus arteriosus shunts blood from the pulmonary artery to the aorta, bypassing the fetal lungs.
