A pregnant client completes the 1-hour glucose tolerance test (GTT) at 26 weeks' gestation. The nurse explains that if the blood glucose result is above to mg/dL. It is considered a positive screening and the client will need a 3-hour oral glucose tolerance test.

Answer and Explanation

The Correct Answer is ["130 to 140"]

The 1-hour GTT is a screening test for gestational diabetes mellitus (GDM) performed between 24–28 weeks of gestation. The client drinks a 50-gram glucose solution, and blood glucose is measured 1 hour later.

A result ≤130–140 mg/dL is considered normal, indicating the client is unlikely to have GDM.
A result above 130–140 mg/dL is considered positive, prompting a 3-hour, 100-gram OGTT to confirm the diagnosis.

Correct Answer is ["A","B","E"]

Explanation

A. Hemolysis occurs due to microvascular endothelial damage, which leads to fragmentation and destruction of red blood cells. Laboratory evidence includes elevated lactate dehydrogenase (LDH >600 U/L), elevated indirect bilirubin, and decreased haptoglobin. This contributes to fatigue, malaise, and jaundice in severe cases.

B. Elevated liver enzymes indicate hepatocellular injury caused by microvascular damage. Laboratory evidence includes AST >70 U/L and mildly to moderately elevated ALT. This liver damage correlates with right upper quadrant or epigastric pain and may also lead to nausea and vomiting.

C. Although often present, severe hypertension is not required for diagnosis. Some women with HELLP may have only mild or normal blood pressure, so elevated blood pressure alone cannot confirm the syndrome.

D. Hyperglycemia is unrelated; blood glucose levels are usually normal in HELLP syndrome. Elevated glucose may suggest another metabolic disorder such as gestational diabetes.

E. Low platelets occur due to platelet aggregation and consumption in the damaged microvasculature. Laboratory evidence includes platelet counts <100,000/mm³. This increases the risk for bleeding, bruising, and complications during delivery.

A. macrosomia. B. preterm birth. C. low birth weight D. congenital anomalies of the central nervous system.

Correct Answer is A

Explanation

A. Macrosomia, defined as a birth weight greater than 4,000–4,500 grams, is the most common fetal complication associated with gestational diabetes. Hyperglycemia in the mother leads to increased glucose transfer across the placenta, stimulating fetal pancreatic insulin production. Fetal hyperinsulinemia acts as a growth-promoting hormone, resulting in excessive fat and muscle deposition and ultimately large-for-gestational-age infants. Macrosomia increases the risk of birth injuries such as shoulder dystocia, clavicle fractures, and the need for cesarean delivery.

B. Preterm birth is not the primary risk associated with GDM. While poorly controlled diabetes can contribute to preterm labor, it is less common than macrosomia. The main concern in GDM is excessive fetal growth, not premature delivery.

C. Low birth weight is not typically associated with gestational diabetes. In fact, infants of mothers with poorly controlled GDM are often larger than average, not smaller, due to fetal hyperinsulinemia and increased nutrient availability.

D. Congenital anomalies, particularly neural tube defects or central nervous system defects, are primarily associated with pregestational diabetes rather than GDM. Gestational diabetes develops later in pregnancy (usually after 24 weeks) when organogenesis has largely occurred, so the risk for major congenital anomalies is minimal.
