A client reports that her last menstrual period began on March 5, 2024. Using
Naegele's rule, what is the client's estimated date of delivery (EDD)?
A. December 5, 2024
B. December 12, 2024
C. December 19, 2024
D. January 12, 2025
Rationale: Naegele's rule calculates the EDD by taking the first day of the last
menstrual period, subtracting 3 months, adding 7 days, and adding 1 year. March
5 minus 3 months is December 5. December 5 plus 7 days is December 12. Adding
1 year yields December 12, 2024.
A client is currently 12 weeks pregnant. She has delivered two babies at 39 weeks,
one at 34 weeks, and had one miscarriage at 8 weeks. She has three living
children. Using the GTPAL system, how should the nurse document this client's
history?
A. G4 T2 P1 A1 L3
B. G5 T2 P1 A1 L3
C. G5 T2 P0 A1 L3
D. G4 T2 P0 A1 L3
Rationale: The GTPAL system stands for Gravida, Term, Preterm, Abortions, and
Living children. G (Gravida) is 5 (the four previous pregnancies plus the current
one). T (Term) is 2. P (Preterm) is 1. A (Abortions) is 1 (miscarriages and elective
abortions before 20 weeks). L (Living) is 3.
,A prenatal client's rubella titer results indicate she is not immune. Which
instruction should the nurse include in the client's discharge teaching?
A. Receive the MMR vaccine immediately
B. Receive the MMR vaccine in the immediate postpartum period
C. Avoid all contact with individuals who have a rash
D. Plan to receive the vaccine during the second trimester
Rationale: The MMR vaccine is a live vaccine and is contraindicated during
pregnancy. Clients who are not immune should receive the vaccine in the
immediate postpartum period. The client should also be instructed to avoid
pregnancy for at least 1 month after receiving the vaccine. Receiving it
immediately (A) or during the second trimester (D) is contraindicated.
A client at 16 weeks gestation is scheduled for a maternal serum alpha-fetoprotein
(MSAFP) screening. The nurse should explain that an elevated MSAFP level may
indicate which condition?
A. Neural tube defect
B. Down syndrome
C. Gestational diabetes
D. Placenta previa
Rationale: An elevated MSAFP level is associated with open neural tube defects,
such as spina bifida and anencephaly, as well as abdominal wall defects. Low
levels of MSAFP are associated with chromosomal abnormalities like Down
syndrome (B). Gestational diabetes (C) and placenta previa (D) are not detected by
MSAFP screening.
, A client at 32 weeks gestation calls the clinic reporting a low backache and a
feeling of pelvic pressure. Which action should the nurse implement?
A. Instruct the client to rest in a supine position for 1 hour
B. Advise the client to come to the clinic immediately for evaluation
C. Reassure the client that these are normal discomforts of pregnancy
D. Tell the client to increase her fluid intake and monitor her temperature
Rationale: Low backache and pelvic pressure are classic signs of preterm labor.
The client is at 32 weeks gestation, and any signs of preterm labor require
immediate evaluation. Resting (A) delays necessary medical intervention. These
are not normal discomforts at this stage (C). Increasing fluids (D) is not the priority
intervention for suspected preterm labor.
A pregnant client asks the nurse why folic acid is important during pregnancy.
Which response by the nurse is best?
A. It helps prevent gestational diabetes.
B. It helps prevent neural tube defects.
C. It helps prevent postpartum hemorrhage.
D. It helps prevent pregnancy-induced hypertension.
Rationale: Folic acid is essential for the development of the neural tube. Adequate
intake prior to conception and during early pregnancy significantly reduces the risk
of neural tube defects such as spina bifida. It does not directly prevent gestational
diabetes (A), postpartum hemorrhage (C), or pregnancy-induced hypertension (D).
During a prenatal assessment, the nurse notes a bluish discoloration of the cervix.
The nurse should document this finding as which of the following?
A. Hegar's sign
