The nurse is providing education to a pregnant woman whose genetic testing confirms her fetus has Down syndrome. The nurse understands that Down syndrome is an example of which abnormality?

Correct Answer: B

Rationale: The correct answer is B: Abnormality of chromosomal number. Down syndrome is caused by an extra copy of chromosome 21, leading to trisomy 21. This results in characteristic physical features and intellectual disability. Chromosomal translocation (A) involves the swapping of genetic material between chromosomes. Multifactorial monosomy inheritance (C) refers to a combination of genetic and environmental factors leading to the loss of a chromosome. Autosomal-recessive inheritance (D) requires two copies of a mutated gene to be present for the disorder to manifest, which is not the case in Down syndrome.

Correct Answer: A

Rationale: The correct answer is A: Semen analysis. This is the first test performed because it helps assess male fertility by evaluating sperm count, motility, and morphology. It is a non-invasive and cost-effective test that can provide valuable insights into the couple's fertility issues. Testicular biopsy (B) is an invasive procedure and typically not the initial test. Endometrial biopsy (C) evaluates the uterine lining and is usually performed later in the evaluation process. Hysterosalpingography (D) is a test to assess the fallopian tubes and uterus in females, which is also not typically the first test performed when evaluating infertility in a couple.

Correct Answer: B

Rationale: The correct answer is B, recently diagnosed with polycystic ovarian syndrome (PCOS). PCOS is a common hormonal disorder that can affect a woman's fertility by causing irregular ovulation or no ovulation. This can make it difficult to conceive. - Choice A (asthma with inhaler): Asthma does not directly impact fertility. - Choice C (polyps removal): External polyps removal does not typically affect fertility. - Choice D (sinus headaches): Seasonal sinus headaches do not directly impact fertility. In summary, PCOS can affect fertility due to hormonal imbalances affecting ovulation, making it the most relevant medical condition in this context.

Correct Answer: A

Rationale: The client's cervical dilation, effacement, and contraction pattern indicate that she is in the latent phase of the first stage of labor. This phase is characterized by cervical dilation of 0 to 3 cm, effacement of 0% to 40%, and contractions every 5 to 10 minutes lasting 30 to 40 seconds. The active phase of the first stage occurs with cervical dilation of 4 to 7 cm, effacement of 40% to 80%, and contractions every 2 to 5 minutes lasting 45 to 60 seconds. The perineal phase of the second stage and early phase of the third stage have different characteristics, making them incorrect choices.
