Question 1 of 5
A nurse is planning care for a client who is to undergo a nonstress test. Which of the following actions should the nurse include in the plan of care?
Correct Answer: D
Rationale: The correct answer is D: Instruct the client to press the provided button each time fetal movement is detected. In a nonstress test, the client is required to monitor fetal movements and press a button each time they are felt. This helps assess fetal well-being by measuring the heart rate in response to movement. This action is essential for the accurate interpretation of the test results. Maintaining the client NPO (
A) is not necessary for this procedure. Placing the client in a supine position (
B) can lead to decreased blood flow to the fetus. Instructing the client to massage the abdomen (
C) may interfere with the natural fetal movements being monitored.
Therefore, the correct action is to have the client press the button when fetal movement is detected to ensure an accurate assessment of fetal well-being.
Question 2 of 5
Which hormone is responsible for stimulating the growth and development of the ovarian follicles?
Correct Answer: C
Rationale: The correct answer is C: Follicle-stimulating hormone (FSH). FSH stimulates the growth and development of ovarian follicles by promoting the production of estrogen in the ovaries. It helps in the maturation of the follicles and ultimately leads to ovulation. Estrogen (
A) and Progesterone (
B) are hormones produced by the ovaries but do not directly stimulate the growth of ovarian follicles. Luteinizing hormone (LH) (
D) is responsible for triggering ovulation and the formation of the corpus luteum, not for the growth and development of ovarian follicles.
Question 3 of 5
Which of the following hormones is responsible for inducing ovulation?
Correct Answer: D
Rationale: The correct answer is D: Luteinizing hormone (LH). LH surge triggers ovulation by stimulating the release of the mature egg from the ovarian follicle. Estrogen and progesterone play roles in the menstrual cycle but do not directly induce ovulation. FSH is involved in follicular development but not ovulation.
Question 4 of 5
What is the primary hormone responsible for maintaining the endometrium during pregnancy?
Correct Answer: A
Rationale: The correct answer is A: Progesterone. Progesterone is the primary hormone responsible for maintaining the endometrium during pregnancy. It helps to thicken the endometrial lining, ensuring a suitable environment for implantation and supporting the developing embryo. Progesterone also inhibits uterine contractions, preventing premature labor. Estrogen, FSH, and LH do not play a primary role in maintaining the endometrium during pregnancy. Estrogen is involved in the initial thickening of the endometrium, while FSH and LH are primarily responsible for ovulation and follicle development.
Question 5 of 5
Which of the following tests is used to assess fetal lung maturity?
Correct Answer: D
Rationale: The correct answer is D: Lecithin-sphingomyelin (L/S) ratio. This test is used to assess fetal lung maturity by measuring the ratio of two substances found in the amniotic fluid. An L/S ratio greater than 2:1 is indicative of mature fetal lungs. This test is crucial in determining if a baby can breathe adequately after birth. The other choices are incorrect because:
A) Non-stress test monitors fetal heart rate and movements,
B) Biophysical profile assesses fetal well-being, and
C) Amniocentesis is a procedure to collect amniotic fluid for genetic testing.
