Correct Answer is ["A","B","C","E"]
Explanation
Choice A Reason: Nausea is a common presumptive sign of pregnancy, especially in the first trimester. It is caused by hormonal changes and may be accompanied by vomiting.
Choice B Reason: Abdominal enlargement is another presumptive sign of pregnancy, as the uterus grows to accommodate the developing fetus. It may be noticeable as early as 12 weeks of gestation.
Choice C Reason: A positive pregnancy test is a presumptive sign of pregnancy, as it detects the presence of human chorionic gonadotropin (hCG), a hormone produced by the placenta. However, it is not a definitive sign, as it may be affected by other factors such as medications, tumors, or false positives.
Choice D Reason: Braxton Hicks contractions are not a presumptive sign of pregnancy, but a probable sign. They are irregular and painless contractions of the uterus that occur throughout pregnancy, but become more frequent and noticeable in the third trimester. They are also known as false labor contractions.
Choice E Reason: Amenorrhea, or the absence of menstrual periods, is a presumptive sign of pregnancy, as it indicates that ovulation has ceased. However, it is not a definitive sign, as it may be caused by other factors such as stress, illness, or hormonal imbalances.
Correct Answer is ["31"]
Explanation
The correct answer is 31 gtts/min. To calculate the infusion rate, the nurse should use the following formula:
Infusion rate (gtts/min) = Volume (mL) x Drop factor (gtts/mL) / Time (min)
Plugging in the given values, we get:
Infusion rate (gtts/min) = 1000 mL x 15 gtts/mL / 480 min
Infusion rate (gtts/min) = 31.25 gtts/min
Rounding to the nearest whole number, we get 31 gtts/min.
