The nurse is preparing a client for an amniocentesis. What is the priority nursing action before the procedure?

Correct Answer: C

Rationale: The correct answer is C: Ensure informed consent is signed. Before any invasive procedure like an amniocentesis, it is essential to ensure that the client has full understanding of the risks, benefits, and alternatives. This is crucial for autonomy and ethical practice. Administering IV fluids (choice A) is not a priority before an amniocentesis. Obtaining baseline vital signs (choice B) is important but not the priority over informed consent. Positioning the client in the Trendelenburg position (choice D) is not necessary for an amniocentesis procedure.

Correct Answer: C

Rationale: The correct answer is C because nuchal translucency testing is primarily used to screen for chromosomal abnormalities, such as Down syndrome, in the fetus. This test measures the thickness of the fluid-filled space at the back of the baby's neck. It is typically done between 11 and 14 weeks of pregnancy. This testing helps to assess the risk of genetic conditions in the fetus. Option A is incorrect because nuchal translucency testing does not screen for fetal anemia. Option B is incorrect because it does not detect neural tube defects. Option D is incorrect because it does not confirm gestational age.

Correct Answer: D

Rationale: The correct answer is D, verifying signed informed consent. This is the priority because it ensures the client's understanding and agreement to the procedure, respecting their autonomy. Obtaining baseline vital signs (A) is important but not the priority before surgery. Inserting a urinary catheter (B) may be needed but is not the priority over informed consent. Administering antibiotics (C) is important for preventing infection but should not take precedence over confirming the client's informed consent.

Correct Answer: C

Rationale: Step 1: In the second stage of labor, the baby is descending into the birth canal for delivery. Step 2: Intense rectal pressure is a common sensation as the baby moves down. Step 3: This indicates progress in labor as the baby is descending. Step 4: Choice A is incorrect as breech position presents differently. Step 5: Choice B is incorrect as incomplete cervical dilation may not cause rectal pressure. Step 6: Choice D is incorrect as effective labor contractions are needed for descent.

Correct Answer: A

Rationale: The correct answer is A: Increased thirst and urination. In gestational diabetes, increased thirst and urination can indicate uncontrolled blood sugar levels, which can harm the fetus. This symptom suggests hyperglycemia and requires immediate intervention. B: Fasting blood glucose of 100 mg/dL is within the normal range for pregnancy and not concerning. C: Weight gain of 1 pound in a week can be normal in the third trimester and not specific to gestational diabetes. D: Proteinuria of +1 is more concerning for preeclampsia rather than gestational diabetes.
