Assessment of a pregnant woman and her fetus reveals tachycardia and hypertension. There is also evidence suggesting vasoconstriction. The nurse would question the woman about use of which substance?

Choice A Reason: This is correct because cloudy malodorous fluid indicates that the amniotic fluid is contaminated with bacteria or other microorganisms that can cause infection in the woman or the fetus. Normally, amniotic fluid is clear and odorless.

Choice B Reason: This is correct because abdominal tenderness suggests that the woman has inflammation or irritation of the uterus or other pelvic organs due to infection. Abdominal tenderness can also be accompanied by cramping, pain, or fever.

Choice C Reason: This is correct because fetal bradycardia, which is a slow fetal heart rate below 110 beats per minute, indicates that the fetus is experiencing distress or hypoxia due to infection. Fetal bradycardia can be detected by electronic fetal monitoring or Doppler device.

Choice D Reason: This is correct because elevated maternal pulse rate, which is a heart rate above 100 beats per minute, indicates that the woman has an increased metabolic demand or systemic inflammation due to infection. Elevated maternal pulse rate can also be caused by dehydration, anxiety, or pain.

Choice E Reason: This is incorrect because decreased C-reactive protein levels do not indicate infection. C-reactive protein (CRP) is a protein that is produced by the liver in response to inflammation or infection. Increased CRP levels can be a sign of infection, but decreased CRP levels can be normal or indicate other conditions such as liver disease or malnutrition.

Choice A Reason: This is incorrect because ambivalence is a mixed or contradictory feeling towards something or someone. It may occur in some women during pregnancy, especially if the pregnancy was unplanned or unwanted. However, it is not the most likely emotional response in the first trimester.

Choice B Reason: This is correct because emotional lability is a rapid and exaggerated change in mood or affect. It may occur in many women during pregnancy due to hormonal fluctuations, physical changes, and psychological stressors. Emotional lability may manifest as increased irritability, anxiety, sadness, or crying spells.

Choice C Reason: This is incorrect because introversion is a personality trait that indicates a preference for solitude and inward focus. It may be present in some women before or during pregnancy, but it is not an emotional response that is specific to the first trimester.

Choice D Reason: This is incorrect because acceptance is a positive attitude that indicates a willingness to embrace the reality of something or someone. It may develop in some women during pregnancy as they adjust to their new role and identity as mothers. However, it is not the most likely emotional response in the first trimester.
