What hormone is responsible for the development and maturation of the ovarian follicles?
- A. follicle-stimulating hormone (FSH)
- B. luteinizing hormone (LH)
- C. estrogen
- D. progesterone
Correct Answer: A
Rationale: Rationale: Follicle-stimulating hormone (FSH) is responsible for the development and maturation of ovarian follicles by stimulating them to grow and produce estrogen. FSH plays a crucial role in the menstrual cycle and acts on the ovaries to promote follicular development. LH surge triggers ovulation, estrogen is produced by the developing follicles and progesterone is primarily produced after ovulation by the corpus luteum. Therefore, A is correct as it directly influences the growth and maturation of ovarian follicles.

A nurse is reviewing laboratory results for client who is pregnant. The Nurse should expect which of the following laboratory values to increase?
- A. RBC count
- B. Bilirubin
- C. Fasting blood glucose
- D. Bun
Correct Answer: A
Rationale: The correct answer is A: RBC count. During pregnancy, an increase in RBC count is expected due to physiological changes in the body to support the increased oxygen demand for the developing fetus. This is known as physiologic anemia of pregnancy. Bilirubin levels may remain stable or decrease during pregnancy. Fasting blood glucose levels may increase due to gestational diabetes, but this is not a universal finding. BUN levels can remain stable or slightly decrease during pregnancy due to increased renal blood flow and glomerular filtration rate.
A patient vaginally delivered an infant at 4750 g moderate shoulder dystocia occurred during the birth. During the initial assessment of the infant the nurse should look for
- A. Erb's palsy
- B. Bell palsy
- C. Bradycardia
- D. Petechiae
Correct Answer: C
Rationale: The correct answer is C: Bradycardia. During shoulder dystocia, the infant may experience umbilical cord compression leading to decreased oxygen supply and potential bradycardia. Bradycardia is a critical sign that requires immediate attention. Erb's palsy (A) is a brachial plexus injury due to shoulder dystocia, not an immediate concern. Bell palsy (B) is a facial nerve paralysis unrelated to birth trauma. Petechiae (D) are small red or purple spots that may indicate bleeding disorders but are not specific to shoulder dystocia.
A client at 28 weeks' gestation is undergoing a glucose tolerance test. What is the purpose of this test?
- A. To detect anemia.
- B. To screen for gestational diabetes.
- C. To assess fetal growth.
- D. To evaluate placental function.
Correct Answer: B
Rationale: The correct answer is B: To screen for gestational diabetes. The glucose tolerance test during pregnancy helps to identify women at risk for developing gestational diabetes, a condition that can lead to complications for both the mother and baby. By measuring blood sugar levels after consuming a glucose solution, healthcare providers can assess how the body processes sugar during pregnancy. This test is specifically designed to detect abnormalities in glucose metabolism during pregnancy.
Choice A: To detect anemia - Anemia is not typically identified through a glucose tolerance test. Anemia is usually diagnosed through a blood test that measures hemoglobin levels.
Choice C: To assess fetal growth - Fetal growth is usually monitored through ultrasound scans and measurements, not through a glucose tolerance test.
Choice D: To evaluate placental function - Placental function is evaluated through other tests like Doppler ultrasound, not through a glucose tolerance test.
A nurse is caring for a client who is at 40 weeks gestation and is in active labor. The client has 6 cm of cervical dilation and 100% cervical effacement. The nurse obtains the client's blood pressure reading as 82/52 mm Hg. Which of the following nursing interventions should the nurse perform?
- A. Prepare for a cesarean birth.
- B. Assist the client to an upright position.
- C. Prepare for an immediate vaginal delivery.
- D. Assist the client to turn onto her side.
Correct Answer: D
Rationale: Correct Answer: D - Assist the client to turn onto her side.
Rationale:
1. Side-lying position improves placental perfusion and circulation, optimizing blood pressure.
2. This position also helps in relieving pressure on major blood vessels, preventing hypotension.
3. It is a non-invasive intervention that can be quickly implemented in the labor setting.
Summary of Other Choices:
A: Preparing for a cesarean birth is not indicated based solely on the client's blood pressure reading.
B: Assisting the client to an upright position may further decrease blood pressure and compromise perfusion.
C: Immediate vaginal delivery is not warranted solely based on the client's blood pressure and cervical dilation.
A nurse is assessing a newborn who was born Post term. Which of the following findings should the nurse expect?
- A. A Rh-negative mother who has an Rh- positive infant
- B. A Rh "“positive mother who has an Rh- negative infant
- C. A Rh-positive mother who has an Rh- positive infant
- D. A Rh- negative mother who has an Rh- negative infant
Correct Answer: A
Rationale: The correct answer is A: A Rh-negative mother who has an Rh-positive infant. Post-term infants are at higher risk for conditions such as Rh incompatibility. Since the mother is Rh-negative and the infant is Rh-positive, there is a potential for Rh incompatibility, leading to hemolytic disease of the newborn. This occurs when the mother's antibodies attack the infant's red blood cells.
Choice B is incorrect because Rh incompatibility occurs when the mother is Rh-negative and the infant is Rh-positive. Choice C is incorrect as both mother and infant being Rh-positive do not lead to Rh incompatibility. Choice D is incorrect because Rh incompatibility does not occur when both mother and infant are Rh-negative.
