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 A
Explanation
Choice A rationale
An intrauterine device (IUD) is contraindicated for a client who has a positive pregnancy test. Inserting an IUD during pregnancy can lead to complications such as infection, miscarriage, and preterm birth. It is crucial to confirm the absence of pregnancy before IUD insertion.
Choice B rationale
A history of gallbladder disease does not contraindicate the use of an IUD. IUDs are primarily contraindicated in cases of active pelvic infection, certain uterine abnormalities, and confirmed pregnancy, but not gallbladder disease.
Choice C rationale
While smoking is a significant risk factor for many health issues, including cardiovascular disease, it is not a direct contraindication for the use of an IUD. However, smokers should be counseled about the risks of smoking and offered support to quit.
Choice D rationale
Being nulliparous (having never given birth) is not a contraindication for IUD use. IUDs can be safely used by nulliparous women, though some might have a slightly higher risk of expulsion or insertion-related discomfort compared to women who have given birth.
