A patient in labor is undergoing an epidural block and is given intravenous fluid. What is the purpose of this?
- A. To treat hypotension that results from hemorrhage
- B. To increase urine output
- C. To treat insensible fluid losses
- D. To treat hypotension that results from sympathetic blockade
Correct Answer: D
Rationale: The correct answer is D: To treat hypotension that results from sympathetic blockade. When an epidural block is administered during labor, sympathetic blockade can lead to a drop in blood pressure. By providing intravenous fluid, the goal is to increase preload and maintain blood pressure to counteract the hypotension caused by sympathetic blockade.
A: Treating hypotension from hemorrhage is not the primary purpose in this scenario.
B: Increasing urine output is not the main goal of giving intravenous fluid during an epidural block.
C: Treating insensible fluid losses is not the immediate concern when a patient is experiencing hypotension from sympathetic blockade.
When is the earliest interval that chorionic villus sampling (CVS) can be performed during pregnancy?

A biophysical profile is performed on a pregnant patient. The results show a nonreactive stress test (NST), three episodes of fetal breathing movements (FBMs), limited gross movements, opening and closing of the hand indicating the presence of fetal tone, and adequate amniotic fluid index (AFI). What is the correct interpretation of this test result?
- A. A score of 10 would indicate that the results are equivocal.
- B. A score of 8 would indicate normal results.
- C. A score of 6 would indicate that birth should be considered as a possible treatment option.
- D. A score of 9 would indicate reassurance.
Correct Answer: B
Rationale: A biophysical profile score of 8-10 is considered normal, indicating fetal well-being.
When assessing the fruit intake of a pregnant client, the nurse notes that the client usually eats 1 piece of fruit per day and drinks a 12 oz glass of fruit juice per day. Which of the following is the most important communication for the nurse to make?
- A. You are effectively meeting your daily fruit requirements.
- B. Fruit juices are excellent sources of folic acid.
- C. It would be even better if you were to consume more whole fruits and less fruit juice.
- D. Your fruit intake far exceeds the recommended daily fruit intake.
Correct Answer: C
Rationale: Whole fruits provide fiber and additional nutrients compared to fruit juices, which may contain added sugars. Encouraging increased consumption of whole fruits aligns with healthy dietary guidelines for pregnancy.

- B. Drink orange juice before rising.
- C. Consume 1 teaspoon of nutmeg each morning.
- D. Eat 3 large meals plus a bedtime snack.
Correct Answer: A
