A nurse is caring for a client who is pregnant and is at the end of her first trimester. The nurse should place the Doppler ultrasound stethoscope in which of the following locations to begin assessing for the fetal heart tones (FHT)?

Just above the umbilicus

Just above the symphysis pubis

The right lower quadrant

The left lower quadrant

Answer and Explanation

The Correct Answer is B

The correct answer is B. Just above the symphysis pubis.

A. Just above the umbilicus: At the end of the first trimester, the uterus is still within the pelvic cavity, and fetal heart tones are typically not detectable above the umbilicus at this stage.

B. Just above the symphysis pubis: This is the correct placement for assessing fetal heart tones during the first trimester. The fetal heart is usually located low in the pelvis during early pregnancy, making it most easily heard just above the pubic bone.

C. The right lower quadrant: Fetal heart tones are typically assessed in the midline of the abdomen, and focusing on the lower quadrants may not be the optimal location, especially in the first trimester.

D. The left lower quadrant: Similar to the right lower quadrant, focusing on the lower quadrants may not be the most appropriate location for assessing fetal heart tones during the first trimester.

Correct Answer is C

Explanation

Choice A Reason:

Percutaneous umbilical blood sampling (PUBS) is not appropriate. This invasive procedure involves sampling blood from the umbilical cord and is not typically used in the context of a positive contraction stress test.

Choice B Reason:

Amnioinfusion is not appropriate. Amnioinfusion is a procedure in which sterile fluid is infused into the amniotic cavity to alleviate conditions such as oligohydramnios. It is not a primary diagnostic test for assessing fetal well-being.

Choice C Reason:

Biophysical profile (BPP) is appropriate. The biophysical profile is a diagnostic test that assesses the well-being of the fetus by evaluating various parameters, including fetal heart rate, fetal breathing movements, fetal movements, fetal tone, and the amniotic fluid volume. This test provides additional information to assess fetal well-being and can help guide decisions about the timing and mode of delivery.

Choice D Reason:

Chorionic villus sampling (CVS) is inappropriate. CVS is a prenatal test used for diagnosing certain genetic conditions but is not indicated in the context of a positive contraction stress test.

A. Cover the newborn's eyes while under the phototherapy light: It is important to protect the newborn's eyes from the bright light during phototherapy. Covering the eyes with an eye mask or using a specific eye shield helps prevent potential eye damage. B. Keep the newborn in a shirt while under the phototherapy light: The newborn should ideally be undressed and have as much skin exposed to the phototherapy light as possible. This enhances the effectiveness of the treatment by allowing more skin surface to be exposed to the light. C. Apply a light moisturizing lotion to the newborn's skin: It is generally recommended to avoid applying lotions or oils to the newborn's skin during phototherapy, as these substances can interfere with the effectiveness of the treatment. The skin should be clean and dry. D. Turn and reposition the newborn every 4 hr while undergoing phototherapy: Turning and repositioning the newborn is important for general care, but the frequency may be more frequent than every 4 hours, especially when undergoing phototherapy. The goal is to ensure even exposure of the skin to the light.
