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

The correct answer is: January 18

Choice A: February 24

Reason: This date is incorrect because it does not follow Naegele’s rule accurately. Naegele’s rule involves adding 1 year, subtracting 3 months, and adding 7 days to the first day of the last menstrual period (LMP). For an LMP of April 11, adding 1 year gives April 11, 2024, subtracting 3 months gives January 11, 2024, and adding 7 days results in January 18, 2024.

Choice B: January 18

Reason: This date is correct. Following Naegele’s rule:

Add 1 year to April 11, 2023, resulting in April 11, 2024.
Subtract 3 months, resulting in January 11, 2024.
Add 7 days, resulting in January 18, 2024.

Choice C: January 25

Reason: This date is incorrect because it adds an incorrect number of days. Naegele’s rule specifies adding 7 days, not 14 days.

Choice D: February 18

Reason: This date is incorrect because it subtracts an incorrect number of months and adds an incorrect number of days. The correct subtraction should be 3 months, not 2 months, and the addition should be 7 days, not 37 days.

Correct Answer is C

Explanation

Choice A reason: This is incorrect because gastrointestinal bleeding is not an adverse effect of hydralazine, which is a vasodilator that lowers blood pressure by relaxing the smooth muscles of the blood vessels. Gastrointestinal bleeding can be caused by other conditions such as ulcers, gastritis, or hemorrhoids.

Choice B reason: This is incorrect because sweating is not an adverse effect of hydralazine, but a normal response to vasodilation and heat loss. Sweating can also be caused by other factors such as fever, anxiety, or exercise.

Choice C reason: This is correct because tachycardia is an adverse effect of hydralazine, which can occur as a reflex response to vasodilation and hypotension. Tachycardia can increase the cardiac workload and oxygen demand, which can be harmful for pregnant women with preeclampsia who already have impaired placental perfusion and fetal hypoxia.

Choice D reason: This is incorrect because blurred vision is not an adverse effect of hydralazine, but a symptom of severe preeclampsia that indicates cerebral edema or ischemia. Blurred vision can also be caused by other conditions such as diabetes, glaucoma, or cataracts.

A. Chadwick's sign B. Goodell's sign C. Hegar's sign D. Homan's sign

Correct Answer is A

Explanation

Choice A reason: This is correct because Chadwick's sign is a bluish or purplish discoloration of the cervix, vagina, and vulva caused by increased blood flow to the pelvic area during pregnancy. It is one of the earliest signs of pregnancy and can be observed as early as six to eight weeks of gestation.

Choice B reason: This is incorrect because Goodell's sign is a softening of the cervix due to increased vascularity and edema during pregnancy. It is another early sign of pregnancy and can be detected by palpation around six to eight weeks of gestation.

Choice C reason: This is incorrect because Hegar's sign is a softening of the lower uterine segment or isthmus during pregnancy. It is also an early sign of pregnancy and can be felt by bimanual examination around six to twelve weeks of gestation.

Choice D reason: This is incorrect because Homan's sign is a pain in the calf or popliteal region when the foot is dorsiflexed. It is a sign of deep vein thrombosis, which is a potential complication of pregnancy, but not a normal finding.
