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)?

The correct answer is B. Place the client in the lateral position.

A. Increasing the rate of maintenance IV infusion may be necessary, but the initial action should be to address potential aortocaval compression. Repositioning the client to the lateral position helps alleviate compression on the vena cava and improves blood flow to the uterus.

B. Placing the client in the lateral position is the correct first action. Changing the client's position, particularly from a supine to a side-lying position, can relieve aortocaval compression and improve uteroplacental perfusion.

C. Elevating the client's legs is not the priority in this situation. Repositioning the client to the lateral position is more important to address potential aortocaval compression.

D. Administering oxygen using a nonrebreather mask may be indicated, but repositioning the client to the lateral position is the first action to address potential aortocaval compression. Oxygen administration can follow if necessary.

The correct answer is B. Turn the client onto her side.

A. Administering oxygen to the client is a reasonable intervention in the presence of late decelerations, but turning the client onto her side is the priority action to relieve potential compression of the vena cava and improve fetal oxygenation.

B. Turning the client onto her side is the correct first action.

Late decelerations are often associated with uteroplacental insufficiency. Changing the client's position, especially to the left lateral position, can help alleviate pressure on the vena cava, improving blood flow to the uterus and fetal oxygenation.

C. Increasing the client's IV fluid infusion rate may be considered, but it is not the first action to address late decelerations. Positioning changes should be initiated promptly.

D. Palpating the client's uterus is an assessment that may be done, but it is not the first action when late decelerations are observed. Positioning changes take precedence.
