During a prenatal visit, a pregnant woman says, "I know the amniotic fluid is important, but can you tell me more about it?" When describing amniotic fluid to a pregnant woman, which description would the nurse most likely include?
This fluid acts as a cushion to help protect your baby from injury.
The amount of fluid remains fairly constant throughout the pregnancy.
The fluid is mostly protein to provide nourishment to your baby.
This fluid acts as a transport mechanism for oxygen and nutrients.
The Correct Answer is A
Choice A Reason: This is correct because this description accurately reflects one of the main functions of amniotic fluid, which is to act as a shock absorber and buffer against external forces or movements that could harm the fetus. Amniotic fluid also allows the fetus to move freely and develop its muscles and bones.
Choice B Reason: This is incorrect because this description is false. The amount of amniotic fluid changes throughout the pregnancy, depending on the stage of fetal development and other factors. The normal range of amniotic fluid volume is between 500 and 1000 mL at term. Too much or too little amniotic fluid can indicate a problem with the fetus or the placenta.
Choice C Reason: This is incorrect because this description is false. The fluid is not mostly protein, but mostly water (about 98%). The water comes from the mother's blood plasma and the fetal urine. The remaining 2% of amniotic fluid consists of various substances, such as electrolytes, hormones, enzymes, antibodies, and fetal cells. Amniotic fluid does not provide nourishment to the fetus, but rather protects it from infection and helps regulate its temperature.
Choice D Reason: This is incorrect because this description is false. Amniotic fluid does not act as a transport mechanism for oxygen and nutrients, but rather as a barrier that prevents them from reaching the fetus directly. Oxygen and nutrients are delivered to the fetus through the placenta and the umbilical cord, which are connected to the maternal blood circulation.

Correct Answer is B
Explanation
Choice A Reason: Nagele's rule is a formula that estimates the due date by subtracting three months from the first day of the last menstrual period and adding seven days. However, this method assumes a regular 28-day cycle and may not be accurate for women with irregular cycles or who are unsure of their last menstrual period.
Choice B Reason: Ultrasound is the most accurate method of determining the estimated due date, especially in the first trimester. Ultrasound uses sound waves to create an image of the fetus and measure its size and development. Ultrasound can also detect any abnormalities or complications that may affect the pregnancy.
Choice C Reason: Gestation wheel is a circular calendar that estimates the due date by aligning the first day of the last menstrual period with a corresponding date on the wheel. However, this method also assumes a regular 28-day cycle and may not account for variations in ovulation or implantation.
Choice D Reason: Birth calculator is an online tool that estimates the due date based on various factors such as the last menstrual period, cycle length, ovulation date, conception date, or ultrasound date. However, this method may not be reliable as it depends on the accuracy of the input data and the algorithm used by the calculator.
Correct Answer is ["2"]
Explanation
To calculate how many capsules to administer per dose, the nurse should divide the ordered dose by the available dose and round to the nearest whole number.
The ordered dose is 50 mg.
The available dose is 25 mg per capsule.
Therefore, the number of capsules to administer per dose is 50 mg / 25 mg = 2 capsules.
The answer should be rounded to the nearest whole number and use a leading zero if it applies. Do not use a trailing zero.
Therefore, the final answer is 2 capsules.
