The nurse is teaching the client who is wishing to travel by airplane during the first 36 weeks of her pregnancy. Which is the primary risk of air travel for this client that the nurse should address?
- A. Risk of preterm labor
- B. Deep vein thrombosis
- C. Spontaneous abortion
- D. Nausea and vomiting
Correct Answer: B
Rationale: The primary risk with air travel during pregnancy is DVT. Pregnancy increases the risk of blood coagulation, and prolonged sitting produces venous stasis. Preterm labor is not associated with air travel. The threat of spontaneous abortion diminishes during the second trimester. Spontaneous abortion is not associated with air travel. Although nausea and vomiting can occur, they are not dangerous.
The client in labor received an epidural anesthesia 20 minutes ago. The nurse assesses that the client’s BP is 98/62 mm Hg and that the client is lying supine. What should the nurse do next?
- A. Increase the lactated Ringer’s infusion rate.
- B. Elevate the client’s legs for 2 to 3 minutes.
- C. Place the bed in 10- to 20-degree Trendelenburg.
- D. Position the client in a left side-lying position.
Correct Answer: D
Rationale: The first action is to place the client in a left side-lying position. This displaces the uterus and alleviates aortocaval compression. Increasing the infusion rate may be implemented if repositioning the client does not correct the hypotension. Elevating the client’s legs for 2 to 3 minutes is done with severe or prolonged hypertension to increase blood return from the extremities. It may be implemented after repositioning to left side, increasing the IV rate, and placing in Trendelenburg position. Placing in 10- to 20-degree Trendelenburg position is usually implemented if the BP does not increase within 1 to 2 minutes after repositioning to left side and increasing the IV flow rate.
At this point in the client's pregnancy, which test is typically used to detect genetic disorders?
- A. Amniocentesis
- B. Chorionic villi sampling
- C. Rapid plasma reagin
- D. Ultrasound
Correct Answer: B
Rationale: Chorionic villi sampling is performed at 10-13 weeks to detect genetic disorders, suitable for a 10-week pregnancy.
The nurse is caring for the client who has been in the second stage of labor for the last 12 hours. The nurse should monitor for which cardiovascular change that occurs during this stage of labor?
- A. An increase in maternal heart rate
- B. A decrease in the cardiac output
- C. An increase in the white blood cell (WBC) count
- D. A decreased intravascular volume during contractions
Correct Answer: A
Rationale: Maternal HR is normally increased due to pain resulting from increased catecholamine secretion, fear, anxiety, and increased blood volume. When the laboring client holds her breath and pushes against a closed glottis, intrathoracic pressure rises. Blood in the lungs is forced into the left atrium, leading to a transient increase (not decrease) in cardiac output. Although the WBCS increase to 25,000/mm3 to 30,000/mm3 during labor and early postpartum as a physiological response to stress, this is not a cardiovascular change. During the second stage of labor, the maternal intravascular volume is increased (not decreased) by 300 to 500 mL of blood from the contracting uterus.
The nurse teaches the client to recognize which early labor sign?
- A. Bloody show
- B. Fatigue
- C. Increased appetite
- D. Mild nausea
Correct Answer: A
Rationale: Bloody show, a mucous discharge tinged with blood, is a common early labor sign as the cervix begins to dilate.
