By subtracting 7 days from the first day of the client's last menstrual cycle and then adding 3 months and 1 year
By adding 7 days to the first day of the client's last menstrual cycle and then subtracting 3 months and 1 year
The Correct Answer is A
A. By subtracting 3 months from the first day of the client's last menstrual cycle and then adding 7 days and 1 year: This is Naegele's rule for estimating the due date: subtract 3 months from the first day of the last menstrual period (LMP), add 7 days, and then add 1 year.
B. By adding 3 months to the first day of the client's last menstrual cycle and then subtracting 7 days and 1 year: This reverses the correct order. You subtract 3 months, not add.
C. By subtracting 7 days from the first day of the client's last menstrual cycle and then adding 3 months and 1 year: This calculation incorrectly subtracts days instead of adding days.
D. By adding 7 days to the first day of the client's last menstrual cycle and then subtracting 3 months and 1 year: The rule adds days and subtracts months, but adding a year here is not correct. You add 1 year at the end.

Correct Answer is A
Explanation
A. "A client should avoid consuming undercooked meat while pregnant." Toxoplasmosis, one of the TORCH infections, can be contracted by eating undercooked or raw meat. Avoiding undercooked meat helps prevent this infection, which can cause severe complications for the fetus.
B. "Obtain an immunization against rubella early in pregnancy." Rubella vaccine (part of MMR) is a live virus vaccine and is contraindicated during pregnancy due to the risk of harm to the fetus. Rubella vaccination should be administered before conception or postpartum.
C. "Seek prophylactic treatment if cytomegalovirus is detected during pregnancy." Currently, there is no prophylactic treatment for cytomegalovirus (CMV) during pregnancy. Prevention focuses on hygiene practices, such as frequent handwashing, especially after handling bodily fluids, to reduce the risk of transmission.
D. "A client should avoid crowded places during pregnancy." While avoiding crowded places may reduce exposure to certain infections, it is not a specific strategy for preventing TORCH infections. Other preventative measures, like avoiding raw meat and practicing good hygiene, are more effective.
Correct Answer is A
Explanation
A. Quickening: Quickening refers to the first movements of the fetus felt by the mother, which often feels like fluttering or light movements. It typically occurs between 16 and 20 weeks of gestation.
B. Chloasma: Chloasma refers to the darkened patches of skin that can appear on the face during pregnancy, also known as the "mask of pregnancy."
C. Lightening: Lightening refers to the descent of the fetus into the pelvis in preparation for birth, which usually occurs in the third trimester, not at 18 weeks of gestation.
D. Ballottement: Ballottement is a technique used during a pelvic examination where the examiner taps on the cervix and feels the fetus bounce back. It is a clinical sign rather than something the mother feels.
