Correct Answer is C
Explanation
Choice A rationale
A Papanicolaou test, commonly known as a Pap smear, is used to detect cervical cancer and precancerous changes in the cervix. It does not detect herpes simplex type 1. Herpes simplex virus (HSV) testing is typically done through a swab of the lesion or blood tests to detect antibodies.
Choice B rationale
A glucose tolerance test is performed during pregnancy to screen for gestational diabetes, not to predict hyperglycemia in the baby. This test helps identify how well the mother’s body is managing glucose and ensures that both mother and baby remain healthy during pregnancy.
Choice C rationale
A multiple marker screening, also known as a triple or quad screen, is performed during pregnancy to identify potential neural tube defects, such as spina bifida, and chromosomal abnormalities like Down syndrome. This test measures specific substances in the mother’s blood to assess the risk of these conditions.
Choice D rationale
Group B streptococcus (GBS) screening is performed to detect the presence of GBS bacteria in the mother’s body, not to determine the presence of sexually transmitted infections (STIs). GBS can cause serious infections in newborns, so it is important to identify and treat it before delivery.
Correct Answer is B
Explanation
Choice A rationale
Feeding the baby six times a day is not sufficient. Newborns typically need to be fed 8-12 times in 24 hours to ensure they receive adequate nutrition and to establish a good milk supply.
Choice B rationale
Recognizing that the baby sucking on his hands is a hunger cue is correct. This is an early sign of hunger, and responding to these cues helps ensure the baby is fed before becoming too upset.
Choice C rationale
Feeding the baby for 10 minutes on each breast may not be adequate. The duration of feeding can vary, and it is important to allow the baby to feed until they are satisfied, which may take longer than 10 minutes.
Choice D rationale
Waking the baby at least every 6 hours at night for feedings is not recommended. Newborns should be fed more frequently, typically every 2-3 hours, including during the night, to ensure they receive enough nutrition.
