Of the following karyotype results, which indicates a finding of Turner syndrome?
- A. 46 XY
- B. 46 YY
- C. 46 XX
- D. 46 X
Correct Answer: D
Rationale: Certainly. The correct answer is D (46 X) for Turner syndrome. Turner syndrome is characterized by a missing or partially missing X chromosome in females. Therefore, a karyotype of 45,X or 46,X would indicate Turner syndrome. Choice A (46 XY) is a normal male karyotype, B (46 YY) is not a valid karyotype, and C (46 XX) is a normal female karyotype.

A woman undergoing evaluation of infertility states, "At least when we're through with all of these tests, we will know what is wrong." The nurse's best response is
- A. "I know the test will identify what is wrong."
- B. "I'm sure that once you finish these tests, your problem will be resolved."
- C. "Even with diagnostic testing, infertility remains unexplained in about 20% of couples."
- D. "Once you've identified your problem, you may want to look at the option of adoption."
Correct Answer: C
Rationale: The correct answer is C because it acknowledges the uncertainty in diagnosing infertility, which can remain unexplained in about 20% of couples even after testing. This response is the best because it provides realistic information without giving false hope or making assumptions.
Choice A is incorrect because it asserts that the tests will definitely identify the problem, which is not always the case. Choice B is incorrect as it assumes the problem will be resolved after testing, which may not be true. Choice D is incorrect as it jumps to the conclusion of adoption without addressing the uncertainty of infertility testing.

A woman telephones the prenatal clinic and reports that her water just broke. Which suggestion by the nurse would be most appropriate?
- A. Call us back when you start having contractions.
- B. Come to the clinic or emergency department for an evaluation.
- C. Drink 3 to 4 glasses of water and lie down.
- D. Come in as soon as you feel the urge to push.
Correct Answer: B
Rationale: When a woman's water breaks, there is an increased risk of infection and cord prolapse, making it important for the woman to seek evaluation at the clinic or emergency department. Waiting for contractions to start, drinking water and lying down, and waiting to come in only when feeling the urge to push are not appropriate responses in this situation.
A woman in her 40th week of pregnancy calls the nurse at the clinic and says she is not sure whether she is in true or false labor. Which statement by the client would lead the nurse to suspect that the woman is experiencing false labor?
- A. I'm feeling contractions mostly in my back.
- B. My contractions are about 6 minutes apart and regular.
- C. The contractions slow down when I walk around.
- D. If I try to talk to my partner during a contraction, I can't.
Correct Answer: C

- A. Eggs or oocytes develop within ovarian follicles. The purpose of the medication is to stimulate development of ovarian follicles.
- B. Follistim is a manufactured form of FSH, a hormone released from the pituitary gland during the menstrual cycle.

The nurse should educate Cindy on the medication's purpose, how it works, and the importance of follicle development in the ovulation process.
Choice B is incorrect as Follistim is not a manufactured form of FSH but a specific form of follitropin.
Choice C is incorrect as rapid weight gain is not a typical side effect of ovulation induction with Follistim.
Choice D is incorrect as the typical side effects of Follistim include ovarian hyperstimulation syndrome, abdominal pain, and bloating, not breast tenderness, changes in mood, or depression.
