A nurse is reinforcing teaching with a client about laboratory testing during pregnancy. Which of the following statements should the nurse include in the teaching?

(a) "Wear an underwire bra between feedings."
Wearing an underwire bra between feedings can compress breast tissue and impede milk flow, increasing the risk of mastitis. This recommendation is incorrect and could contribute to the development of mastitis rather than preventing it.

(b) "You should use a breast pump if you plan to return to work."
Regularly expressing breast milk with a breast pump, especially if planning to return to work, helps maintain milk supply and prevents engorgement, which can lead to mastitis. This recommendation encourages appropriate breastfeeding practices to prevent mastitis.

(c) "Wash your nipples with soap and water daily."
While maintaining good breast hygiene is important, excessive washing with soap and water can strip the nipples of natural oils and increase the risk of dryness and cracking, which may predispose to mastitis. This recommendation is not the most effective strategy for preventing mastitis.

(d) "Cover your breasts immediately after feedings."
Covering the breasts immediately after feedings may trap moisture and promote bacterial growth, increasing the risk of mastitis. It is important to allow the breasts to air dry after feedings to prevent moisture buildup and promote healing of any cracked nipples. This recommendation is not appropriate for preventing mastitis.

(A) "A Papanicolaou test will be performed to detect the presence of herpes simplex type 1."
The Papanicolaou (Pap) test is not performed during pregnancy to detect herpes simplex type 1. The Pap test is a cervical cancer screening test that detects abnormal cervical cells, usually caused by human papillomavirus (HPV) infection or other factors. It is not used to detect herpes simplex type 1.

(B) "A group B streptococcus screening will be performed to determine the presence of STs."
Group B Streptococcus (GBS) screening is performed during pregnancy to detect the presence of GBS bacteria in the mother's genital and rectal areas. GBS is a common bacteria that can cause serious infections in newborns if passed from the mother during childbirth. GBS screening is not related to sexually transmitted infections (STIs).

(C) "A multiple marker screening will be performed to identify neural tube defects."
Multiple marker screening, also known as maternal serum screening or quad screen, is a routine prenatal test performed between 15 and 20 weeks of gestation. It helps identify the risk of certain chromosomal abnormalities, including neural tube defects like spina bifida and anencephaly. This screening measures the levels of certain proteins in the mother's blood to assess the risk of these birth defects.

(D) "A glucose tolerance test will be performed to predict hyperglycemia in your baby."
A glucose tolerance test (GTT) is performed during pregnancy to diagnose gestational diabetes mellitus (GDM), a condition characterized by high blood sugar levels during pregnancy. The purpose of the GTT is to identify maternal hyperglycemia, which can lead to complications for both the mother and the baby. The test is not performed to predict hyperglycemia specifically in the baby.
