A provider prescribes quetiapine 50 mg PO divided equally every 12 hours for 3 days. Available is quetiapine 25 mg tablets. How many tablets should the nurse administer per dose on day 3? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason: This option is incorrect because it underestimates the number of pregnancies (gravida) and overestimates the number of preterm births (preterm). The client has had four pregnancies (twins count as one pregnancy), not three. The client has had one preterm birth (the twins), not two.

Choice B Reason: This option is correct because it accurately reflects the client's obstetric history. GTPAL stands for Gravida, Term, Preterm, Abortions, and Living children. Gravida is the number of pregnancies a woman has had, regardless of outcome. Term is the number of pregnancies that ended at or beyond 37 weeks gestation. Preterm is the number of pregnancies that ended between 20 and 36 weeks gestation. Abortions are the number of pregnancies that ended before 20 weeks gestation, either spontaneously or induced. Living children are the number of children who are alive at present.
The client has had four pregnancies (gravida), one term birth (the son), one preterm birth (the twins), one abortion (the miscarriage), and three living children (the twins and the son).

Choice C Reason: This option is incorrect because it overestimates the number of preterm births (preterm) and underestimates the number of living children (living). The client has had one preterm birth (the twins), not two. The client has three living children (the twins and the son), not one.

Choice D Reason: This option is incorrect because it underestimates the number of pregnancies (gravida) and overestimates the number of abortions (abortions) and preterm births (preterm). The client has had four pregnancies (twins count as one pregnancy), not three. The client has had one abortion (the miscarriage), not two. The client has had one preterm birth (the twins), not two.

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.
