A client's last menstrual period was April 11. Using Naegele's rule, her estimated date of birth (EDB) would be:

February 24

January 18

January 25

February 18

Answer and Explanation

The Correct Answer is B

Choice A Reason: This is incorrect because it is too early. Naegele's rule is a formula that estimates the date of birth by adding one year, subtracting three months, and adding seven days to the date of the last menstrual period. Applying this rule to April 11 gives February 18, not February 24.

Choice B Reason: This choice is correct because applying Naegele’s rule to the provided menstrual date (add seven days to the LMP, then subtract three months) produces the expected estimated delivery timeframe. The method yields the appropriate calendar month and day consistent with a full-term pregnancy calculation.

Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.

Choice D Reason: This option is incorrect because it places the estimated delivery about one month later than the correct result. It appears to come from adding months without the proper day adjustment or from misapplying Naegele’s rule, resulting in a date that is too far into February.

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because cervical insufficiency is a condition where the cervix dilates prematurely and painlessly during pregnancy, leading to preterm delivery or second trimester abortion. It is not a common cause of first trimester abortion, which occurs before 12 weeks of gestation.

Choice B Reason: This is incorrect because uterine fibroids are benign tumors that grow in or on the uterus. They may cause heavy bleeding, pain, or infertility, but they are not a common cause of first trimester abortion. They may increase the risk of miscarriage in later stages of pregnancy.

Choice C Reason: This is correct because fetal genetic abnormalities are the most common cause of first trimester abortion, accounting for up to 70% of cases. Fetal genetic abnormalities are errors in the number or structure of chromosomes that occur during fertilization or cell division. They can cause developmental defects or fetal demise that result in spontaneous abortion.

Choice D Reason: This is incorrect because maternal disease is not a common cause of first trimester abortion. Maternal disease refers to any medical condition that affects the mother's health or pregnancy outcome, such as diabetes, hypertension, thyroid disorders, or infections. Maternal disease may increase the risk of miscarriage in later stages of pregnancy or cause other complications such as preterm labor or preeclampsia.

A. Homelessness B. Age C. BP 110/70 D. BMI 17.5 E. Prenatal care F. Prenatal history

Correct Answer is ["A","D","E","F"]

Explanation

Choice A Reason: Homelessness is a risk factor for high-risk pregnancy because it exposes the woman to various challenges and stressors that can affect her health and well-being. Homeless women may face difficulties in accessing adequate nutrition, hygiene, safety, shelter, transportation, and health care. They may also experience higher levels of violence, substance abuse, mental illness, and social isolation. These factors can increase the risk of infections, complications, preterm birth, low birth weight, and infant mortality.

Choice B Reason: Age is not a risk factor for high-risk pregnancy in this case because the woman is 22 years old, which is within the optimal age range for childbearing. The optimal age range is considered to be between 20 and 35 years old, as women in this age group tend to have fewer complications and better outcomes than women who are younger or older. Women who are younger than 20 or older than 35 are considered to have advanced maternal age or adolescent pregnancy, respectively, which are risk factors for high-risk pregnancy.

Choice C Reason: BP 110/70 is not a risk factor for high-risk pregnancy because it is within the normal range for blood pressure. The normal range for blood pressure is considered to be between 90/60 and 120/80 mmHg. Blood pressure that is too high or too low can indicate problems such as preeclampsia, eclampsia, or hypotension, which are risk factors for high-risk pregnancy.

Choice D Reason: BMI 17.5 is a risk factor for high-risk pregnancy because it indicates that the woman is underweight. BMI stands for body mass index, which is a measure of body fat based on height and weight. The normal range for BMI is considered to be between 18.5 and 24.9 kg/m2. BMI that is too low or too high can indicate problems such as malnutrition, obesity, or gestational diabetes, which are risk factors for high-risk pregnancy.

Choice E Reason: Prenatal care is a risk factor for high-risk pregnancy because it indicates that the woman has not received adequate medical attention and support during her pregnancy. Prenatal care is essential for ensuring the health and well-being of both the mother and the baby. Prenatal care involves regular visits to a health care provider who can monitor the progress of the pregnancy, screen for any complications or infections, provide education and counseling, and prescribe any necessary medications or interventions. Lack of prenatal care can increase the risk of maternal mortality, morbidity, preterm birth, low birth weight, congenital anomalies, and infant mortality.

Choice F Reason: Prenatal history is a risk factor for high-risk pregnancy because it indicates that the woman has had previous pregnancies that ended in miscarriage or stillbirth. Prenatal history can provide important information about the woman's reproductive health and potential complications that may recur or affect her current pregnancy. Previous pregnancy losses can indicate problems such as genetic abnormalities, chromosomal disorders, infections, immunological factors, hormonal imbalances, uterine abnormalities, or placental issues. These factors can increase the risk of spontaneous abortion, fetal demise, preterm birth, intrauterine growth restriction (IUGR), or placenta previa.
