What routine lab tests should a pregnant person have in the first trimester? Select all that apply.
- A. complete blood count (CBC)
- B. blood type and Rh factor
- C. urinalysis
- D. thyroid function tests
Correct Answer: D
Rationale: The correct answer is D: thyroid function tests. During pregnancy, thyroid function is crucial for the health of the mother and baby. Thyroid disorders can lead to complications. Testing thyroid function in the first trimester helps detect any abnormalities early.
A, B, and C are commonly performed tests in pregnancy, but they are not specific to the first trimester. A CBC helps assess overall health, blood type and Rh factor are important for identifying potential blood type incompatibilities, and urinalysis can indicate urinary tract infections or other issues. However, these tests are not unique to the first trimester and are typically done throughout pregnancy.

The nurse is counseling a female patient who has unsuccessfully attempted to become pregnant through a variety of methods and treatments for infertility. Which psychosocial manifestation is the nurse most likely to recognize?
- A. Close connections with extended family
- B. Strong intimate relationship with her partner
- C. Difficulty accepting pregnancy if it does occur
- D. Greater focus on career and job opportunities
Correct Answer: C
Rationale: The correct answer is C: Difficulty accepting pregnancy if it does occur. A patient who has struggled with infertility may have developed emotional barriers or fears related to pregnancy due to past disappointments. This psychosocial manifestation is common in individuals who have faced challenges with fertility. It is important for the nurse to recognize and address this potential issue during counseling.
A: Close connections with extended family is not the most likely psychosocial manifestation in this scenario. While extended family support can be beneficial, it may not be the primary concern for a patient struggling with infertility.
B: Strong intimate relationship with her partner is important for coping with infertility, but it is not the most likely manifestation for the nurse to recognize in this scenario.
D: Greater focus on career and job opportunities is not the most likely psychosocial manifestation for a patient struggling with infertility. While some individuals may prioritize their career, the primary concern in this case is related to emotional challenges with pregnancy acceptance.
An expectant father asks the nurse, “Which part of the mature sperm contains the male chromosome?” What is the correct response by the nurse?
- A. X-bearing sperm
- B. The tail of the sperm
- C. The head of the sperm
- D. The middle portion of the sperm
Correct Answer: C
Rationale: The correct response is C: The head of the sperm. The head of the sperm contains the genetic material, including the male chromosome (Y chromosome). This is where the genetic information determining the sex of the offspring is located. The tail of the sperm is responsible for movement, not genetic material. X-bearing sperm would contain the female chromosome, not the male chromosome. The middle portion of the sperm does not specifically contain the genetic material related to determining the sex of the offspring.
A nurse is conducting prenatal education classes for a group of expectant parents. Which information should the nurse include in her discussion of the purpose of amniotic fluid? (Select all that apply.)
- A. Cushions the fetus
- B. Protects the skin of the fetus
- C. Provides nourishment for the fetus
- D. Allows for buoyancy for fetal movement
Correct Answer: A
Rationale: The correct answer is A: Cushions the fetus. Amniotic fluid acts as a cushion that protects the fetus from physical trauma and provides a stable environment for fetal growth. It helps prevent compression injuries and maintains a constant temperature. The other choices are incorrect because: B) Protects the skin of the fetus: While amniotic fluid does provide some protection, its main purpose is cushioning. C) Provides nourishment for the fetus: The placenta is responsible for providing nourishment to the fetus, not amniotic fluid. D) Allows for buoyancy for fetal movement: While amniotic fluid does allow for buoyancy, its primary function is to cushion the fetus.
Where does conception most commonly occur?
- A. None
- B. In the ampulla of the fallopian tube.
- C. None
- D. None
Correct Answer: B
Rationale: Fertilization typically occurs in the ampulla.
Why might a provider recommend percutaneous umbilical blood sampling? Select all that apply.
- A. an increased risk of Down syndrome shown on a previous scan
- B. to detect Down syndrome in the fetus, as this test provides the most accurate screening
- C. to check for genetic and chromosomal abnormalities the fetus is at high risk for
- D. to verify the blood type of the fetus
Correct Answer: B
Rationale: Percutaneous umbilical blood sampling is recommended to detect Down syndrome accurately by analyzing fetal blood. This is because it directly tests the fetal blood for chromosomal abnormalities like Down syndrome, providing a definitive diagnosis. Other choices are incorrect because A does not specify the need for a direct blood test, C is too general, and D can be determined using other non-invasive methods like amniocentesis.
