What is the hormone responsible for the maintenance of the endometrium during pregnancy and the maturation of mammary gland tissue?
- A. Estrogen
- B. Human chorionic gonadotropin (hCG)
- C. Prolactin
- D. Progesterone
Correct Answer: D
Rationale: The correct answer is D: Progesterone. Progesterone is essential for maintaining the endometrium during pregnancy by promoting its growth and preventing contractions. It also plays a crucial role in preparing the mammary glands for lactation. Estrogen (A) is important in the menstrual cycle but not specifically for maintaining the endometrium during pregnancy. Human chorionic gonadotropin (hCG) (B) is produced by the placenta and is primarily involved in supporting pregnancy and detecting pregnancy tests. Prolactin (C) is responsible for milk production but is not directly related to the maintenance of the endometrium or mammary gland tissue during pregnancy.
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.
The nurse works in a urologist’s office. A male patient is scheduled for routine fertility testing. For which test does the nurse refrain from making preparation?
- A. STI screening
- B. Hormonal levels
- C. Sexual functioning
- D. Ejaculate analysis
Correct Answer: C
Rationale: The correct answer is C: Sexual functioning. The nurse should refrain from making preparation for sexual functioning testing because this is not typically part of routine fertility testing. The focus of routine fertility testing for a male patient in a urologist's office would be on assessing sperm health and quality, which includes tests like semen analysis (choice D). STI screening (choice A) may be necessary to rule out any infections that could affect fertility, and hormonal levels (choice B) are important to assess the endocrine system's role in fertility. However, sexual functioning testing is not directly related to assessing fertility issues in this context.
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.
