A client who is 8 weeks pregnant presents with breast tenderness, morning sickness, and a missed period. Based on the client's symptoms, which of the following, which of the following signs would be classified as presumptive?

A. Burping the infant during and after feeding is an important practice to release swallowed air, reduce discomfort, and prevent spitting up or gas. Burping as needed and during natural pauses in feeding demonstrates proper technique and understanding of infant feeding safety and comfort, indicating correct learning.

B. Adding rice cereal to formula at 2 weeks of age is not recommended. Early introduction of solids or thickened formula can increase the risk of aspiration, overfeeding, and gastrointestinal complications. Solid foods are generally introduced at about 4–6 months of age when the infant is developmentally ready.

C. Warming a bottle in a microwave oven is unsafe. Microwaves can cause uneven heating and “hot spots”, which may burn the infant’s mouth or throat. Safe warming methods include placing the bottle in warm water or using a bottle warmer.

D. Refrigerating leftover formula for the next feeding is inappropriate. Prepared formula should be used within 1–2 hours of feeding, and any leftover milk or formula from a feeding should be discarded to prevent bacterial growth and potential infection.

A. Genital warts are caused by human papillomavirus (HPV) infection. They usually present as painless, cauliflower-like lesions on the external genitalia. Genital warts do not cause cyclical pelvic pain, progressively worsening dysmenorrhea, dyspareunia, irregular bleeding, or infertility, making this an unlikely cause of the client’s symptoms.

B. Pregnancy does not account for chronic, long-term pelvic pain or progressive worsening over several years. Additionally, pregnancy is not a chronic condition and cannot explain the client’s secondary infertility or irregular vaginal bleeding over multiple menstrual cycles.

C. Endometriosis occurs when endometrial tissue grows outside the uterine cavity, most commonly on the ovaries, fallopian tubes, or peritoneum. It is characterized by progressive dysmenorrhea with pain during menstruation that worsens over time, persistent or cyclic pelvic pain often severe, dyspareunia or pain during sexual intercourse, irregular bleeding such as spotting or heavy periods, and infertility due to adhesions and altered pelvic anatomy that can impede conception. The client’s long history of progressively worsening pain, dyspareunia, irregular bleeding, and difficulty conceiving strongly supports endometriosis as the most likely diagnosis.

D. Premenstrual syndrome (PMS) involves physical and emotional symptoms, such as mood swings, bloating, breast tenderness, and mild cramps, that occur 1–2 weeks before menstruation. PMS does not cause severe, progressively worsening pelvic pain, dyspareunia, chronic irregular bleeding, or infertility.
