The client asks the nurse how a woman can recognize when she is ovulating.
Which should be the nurse's responses? (Select all that Apply)

Choice A rationale

Basal body temperature drops slightly for 24-48 hours before ovulation, indicating the most fertile period.

Choice B rationale

Luteinizing hormone surges just before ovulation, triggering the release of an egg from the ovary.

Choice C rationale

Vaginal acidity does not significantly decrease during ovulation; it remains relatively constant.

Choice D rationale

Libido often rises during ovulation due to hormonal changes, which can increase the chances of conception.

Choice A rationale

Hepatitis B immune globulin at 1 week followed by hepatitis B vaccine monthly for 6 months is incorrect. This schedule delays the immune response and leaves the infant unprotected during the critical early period when the risk of transmission is highest.

Choice B rationale

Hepatitis B immune globulin and hepatitis B vaccine within 12 hr of birth is the correct approach. This combination provides immediate passive immunity through the immune globulin and active immunity through the vaccine, significantly reducing the risk of hepatitis B transmission from mother to child.

Choice C rationale

Hepatitis B vaccine monthly until the newborn tests negative for the hepatitis B surface antigen is incorrect. Monthly administration alone is insufficient without the initial dose of immune globulin, especially since the infant may remain at risk until the negative test result.

Choice D rationale

Hepatitis B vaccine at 24 hr followed by hepatitis B immune globulin every 12 hr for 3 days is incorrect. The delay in the first vaccine dose reduces its efficacy, and the immune globulin schedule does not align with established guidelines for preventing hepatitis B transmission.
