A 3-month-old baby has been diagnosed with cystic fibrosis (CF). The mother says, 'How could this happen? I had an amniocentesis during my pregnancy and everything was supposed to be normal!' What must the nurse understand about this situation?

Correct Answer: B

Rationale: In this scenario, the correct answer is B) The baby may have an uncommon genetic variant of the disease. This is because cystic fibrosis (CF) is a genetic disorder that can be caused by various mutations in the CFTR gene. While some genetic tests, including amniocentesis, can detect certain common mutations associated with CF, they may not identify all possible genetic variants that can lead to the disease. Therefore, it is possible for a baby to have an uncommon genetic variant of CF that was not detected during the mother's prenatal testing. Option A) Cystic fibrosis cannot be diagnosed by amniocentesis is incorrect because while amniocentesis may detect some common mutations associated with CF, it is not exhaustive and may miss uncommon genetic variants. Option C) It is possible that the laboratory technician made an error is incorrect as the issue lies more with the limitations of the genetic testing methods rather than a technician error. Option D) Instead of obtaining fetal cells the doctor probably harvested maternal cells is incorrect as amniocentesis is specifically designed to obtain fetal cells for genetic testing, and harvesting maternal cells would not provide accurate information about the baby's genetic status. Educationally, this question highlights the complexity of genetic testing for conditions like cystic fibrosis and emphasizes the importance of understanding the limitations of prenatal diagnostic tests in detecting all possible genetic variants that can lead to a disease. It underscores the need for comprehensive genetic counseling and testing to provide accurate information to parents about their baby's health.

Correct Answer: A

Rationale: In this scenario, the correct nursing response is to tell the woman that pregnancy cannot be determined until she misses her next period (Option A). This response is appropriate because clomiphene citrate (Clomid) can mimic early pregnancy symptoms like nausea and frequency of urination. It is crucial to wait until a missed period to confirm pregnancy accurately. Option B is incorrect because sensitive pregnancy testing at this stage may not be conclusive due to the possibility of false positives from the medication. Option C is incorrect as taking a pregnancy test after completing the drug cycle may lead to unnecessary anxiety or false results. Option D is incorrect because merely reassuring the woman without advising further evaluation could delay appropriate pregnancy confirmation. Educationally, this question highlights the importance of understanding the effects of fertility medications on early pregnancy symptoms and the need for accurate timing in pregnancy testing. It emphasizes the significance of evidence-based practice in nursing care and the necessity of providing clear and accurate information to patients to ensure their well-being and informed decision-making.

Correct Answer: B

Rationale: The correct answer is B because delivering the sample to the laboratory within 1 hour of collection ensures the sample is fresh and provides accurate results. Keeping the sample in a cooler (choice A) is unnecessary and may not be feasible. Collecting the sample during frequent sexual activity (choice C) can skew results. Withdrawal method (choice D) may not provide an adequate sample for analysis. Timing and freshness are crucial for accurate results.

Correct Answer: A

Rationale: The correct answer is A. Cindy is prescribed Follistim AQ to stimulate the development of ovarian follicles, where eggs or oocytes develop. This medication helps in ovulation induction. 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.

Correct Answer: C

Rationale: Rationale: C is correct because hysterosalpingogram involves injecting a radiopaque dye into the uterine cavity to visualize the uterus and fallopian tubes. This helps identify any blockages or abnormalities. A is incorrect as the procedure is usually done without general anesthesia. B is incorrect as the procedure is typically scheduled in the early follicular phase. D is incorrect as Tylenol may not be sufficient for managing post-procedure cramping.
