A nurse is collecting data from a client during their first prenatal visit. The nurse should identify which of the following findings as a risk factor for gestational diabetes mellitus?
Maternal age of 21 years.
Fasting blood glucose of 72 mg/dL.
Previous newborn weighing 4.8 kg.
Prepregnancy BMI of 23.
The Correct Answer is C
Choice A rationale
Maternal age of 21 years is not considered a significant risk factor for gestational diabetes. Typically, advanced maternal age (35 years or older) is considered a risk factor due to changes in insulin resistance that occur with age.
Choice B rationale
A fasting blood glucose of 72 mg/dL is within the normal range and does not indicate a risk for gestational diabetes. Gestational diabetes is usually diagnosed with fasting blood glucose levels higher than 95 mg/dL.
Choice C rationale
Previous newborn weighing 4.8 kg is a significant risk factor for gestational diabetes. Having a macrosomic (large) baby in a previous pregnancy is linked with an increased risk of developing gestational diabetes in subsequent pregnancies.
Choice D rationale
A prepregnancy BMI of 23 is within the normal range (18.5-24.9) and does not increase the risk of gestational diabetes. Higher BMI levels, particularly above 25, are associated with an increased risk.

Correct Answer is A
Explanation
Choice A rationale
"Decreased BP.”. This is correct because hyperemesis gravidarum can lead to dehydration, which in turn can cause hypotension (decreased blood pressure).
Choice B rationale
"WBC count 15,000/mm³ (5,000 to 15,000/mm³).”. This is incorrect because while WBC count can be elevated due to stress or infection, it is not a primary manifestation of hyperemesis gravidarum.
Choice C rationale
"Pruritus.”. This is incorrect because pruritus is not commonly associated with hyperemesis gravidarum. It is more likely related to other conditions like cholestasis of pregnancy.
Choice D rationale
"Hemoglobin 18 g/dL (11 to 16 g/dL).”. This is incorrect because an elevated hemoglobin level is not a direct manifestation of hyperemesis gravidarum, although dehydration can potentially concentrate blood components and slightly elevate hemoglobin.
Correct Answer is A
Explanation
Choice A rationale
Deep-vein thrombosis (DVT) is a contraindication for diaphragm use due to the increased risk of thromboembolic events with estrogen-based contraceptives.
Choice B rationale
Tobacco use, although a risk factor for cardiovascular disease, is not a direct contraindication for diaphragm use, which is a non-hormonal contraceptive method.
Choice C rationale
Recurrent urinary tract infections are a contraindication for diaphragm use due to the risk of infection exacerbation from device insertion.
Choice D rationale
History of positive group B streptococcus B-hemolytic is not a contraindication for diaphragm use; it typically relates to pregnancy and neonatal infection risk.
