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 D

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 is incorrect because it is too early. Naegele's rule gives February 18, not January 18.

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

Choice D Reason: This is correct because it follows Naegele's rule. Adding one year, subtracting three months, and adding seven days to April 11 gives February 18.

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because sickle-cell anemia is a genetic disorder that affects the shape and function of the red blood cells. It is not related to the AFP level, which is a protein produced by the fetal liver and yolk sac.

Choice B Reason: This is incorrect because cardiac defects are abnormalities in the structure or function of the heart. They are not related to the AFP level, which is a marker of neural tube defects and abdominal wall defects.

Choice C Reason: This is correct because Down syndrome is a chromosomal disorder that results from an extra copy of chromosome 21. It is associated with a decreased AFP level, as well as increased levels of human chorionic gonadotropin (hCG) and unconjugated estriol (uE3).

Choice D Reason: This is incorrect because respiratory disorders are problems that affect the lungs and breathing. They are not related to the AFP level, which reflects the fetal development and integrity.

Correct Answer is ["415"]

Explanation

To calculate the amount of NG drainage, the nurse should subtract the amount of irrigation fluid from the amount of fluid in the NG canister. The irrigation fluid is not part of the drainage, but rather a way to keep the NG tube patent and prevent clogging.

The amount of irrigation fluid is 30 mL x 2 = 60 mL.

The amount of fluid in the NG canister is 475 mL.

Therefore, the amount of NG drainage is 475 mL - 60 mL = 415 mL.

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 415 mL.
