What are functions of the placenta?

The nurse is providing education to a pregnant person at 10 weeks’ gestation who is experiencing nausea and vomiting. The nurse is aware the nausea and vomiting are due to which hormone produced by the placenta?
- A. relaxin
- B. human chorionic gonadotropin
- C. human placental lactogen
- D. luteinizing hormone
Correct Answer: B
Rationale: The correct answer is B: human chorionic gonadotropin (hCG). At 10 weeks' gestation, hCG is the hormone produced by the placenta responsible for nausea and vomiting, known as morning sickness. hCG levels peak around this time, coinciding with the onset of these symptoms. Relaxin (A), human placental lactogen (C), and luteinizing hormone (D) are not directly associated with causing nausea and vomiting in pregnancy.
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.
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.
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.
