Which of the following maternal cardiovascular findings is expected during labor?

1. Increased cardiac output
2. Decreased pulse rate
3. Decreased white blood cell count
4. Decreased blood pressure

Question 2

A premature infant never seems to sleep longer than an hour at a time. Each time a light is turned on, an incubator closes, or people talk near her crib, she wakes up and cries inconsol-ably until held.

The correct nursing diagnosis is ineffective coping related to: 1. severe immaturity.
2. environmental stress.
3. physiologic distress.
4. interpersonal interactions.

Answer to Question 1

1
1. Correct. During each contraction, 400 ml of blood is emptied from the uterus into the maternal vascular system. This increases cardiac output by about 10 to 15 in the first stage of labor and by about 30 to 50 in the second stage.
2. Incorrect. The heart rate will increase slightly during labor.
3. Incorrect. The WBC count can increase during labor.
4. Incorrect. During the first stage of labor, uterine contractions cause systolic readings to increase by about 10 mm Hg. During the second stage of labor, contractions may cause sys-tolic pressures to increase by 30 mm Hg and diastolic readings to increase by 25 mm Hg.

Answer to Question 2

2
1, 3, 4. Incorrect. Light and sound are known adverse stimuli that add to an already stressed premature infant.
2. Correct. This nursing diagnosis is the most appropriate for this infant.
