Which analysis of maternal serum may predict chromosomal abnormalities in the fetus?

Choice A reason: Limiting time spent wearing a wet bathing suit is a good preventive measure, as it can reduce the moisture and warmth that can promote the growth of bacteria and fungi in the genital area. The nurse should advise the 15-year old to change into dry clothes as soon as possible after swimming or bathing.

Choice B reason: Not douching is a good preventive measure, as it can preserve the natural balance of the vaginal flora and pH. The nurse should explain to the 15-year old that douching can wash away the protective mucus and lactobacilli that prevent infections, and it can also introduce harmful substances or microorganisms into the vagina.

Choice C reason: Wearing nylon undergarments is not a good preventive measure, as it can trap heat and moisture in the genital area and create a favorable environment for infections. The nurse should recommend the 15-year old to wear cotton or breathable fabrics that can absorb sweat and allow air circulation.

Choice D reason: Using floral scented bath salts is not a good preventive measure, as it can irritate the genital mucosa and alter the vaginal pH. The nurse should caution the 15-year old to avoid using any products that contain perfumes, dyes, or chemicals in the genital area, as they can cause allergic reactions or infections.

Choice E reason: Decreasing sugar intake is a good preventive measure, as it can lower the risk of yeast infections. The nurse should educate the 15-year old that sugar can feed the growth of Candida albicans, which is a common cause of vaginal candidiasis. The nurse should also encourage the 15-year old to eat a balanced diet that includes probiotics, such as yogurt, to maintain a healthy vaginal flora.

Choice F reason: Avoiding tight-fitting jeans is a good preventive measure, as it can prevent friction and pressure on the genital area. The nurse should suggest the 15-year old to wear loose or comfortable clothing that can reduce the risk of skin irritation or injury, which can lead to infections.

Choice A reason: This is incorrect because providing the patient with handouts is not enough to ensure effective communication. The handouts may not be in the patient's preferred language or may use unfamiliar words or concepts. The nurse should also use other methods, such as interpreters, translators, or visual aids, to convey information to the patient.

Choice B reason: This is incorrect because speaking quickly and efficiently may hinder the patient's comprehension and increase the risk of misunderstanding. The nurse should speak slowly and clearly, using simple and common words, and allow time for the patient to ask questions or clarify information.

Choice C reason: This is correct because assessing whether the patient understands the discussion is essential for effective communication and patient education. The nurse should use techniques such as teach-back, ask-me-3, or show-me to verify the patient's understanding and address any gaps or misconceptions.

Choice D reason: This is incorrect because using maternity jargon may confuse the patient and create barriers to communication. The nurse should avoid using medical terms, abbreviations, or slang that the patient may not be familiar with. The nurse should explain any necessary terms in plain language and use examples or analogies to illustrate them.
