A client with a history of impaired glucose tolerance asks the nurse about the potential impact on her current pregnancy.

The nurse explains that impaired glucose tolerance increases the risk of developing:.

Preterm labor

Ectopic pregnancy

Gestational diabetes

Gestational hypertension

Answer and Explanation

The Correct Answer is C

The correct answer is choice C. Gestational diabetes. Impaired glucose tolerance in pregnancy means that the blood sugar levels are elevated, but not high enough to be diagnosed with diabetes. However, this condition increases the risk of developing gestational diabetes, which is a type of diabetes that occurs only during pregnancy and affects both the mother and the baby.

Choice A is wrong because preterm labor is not directly caused by impaired glucose tolerance, although gestational diabetes may increase the risk of preterm labor.

Choice B is wrong because ectopic pregnancy is not related to impaired glucose tolerance or gestational diabetes. Ectopic pregnancy occurs when a fertilized egg implants outside the uterus, usually in the fallopian tube.

Choice D is wrong because gestational hypertension is not caused by impaired glucose tolerance, although gestational diabetes may increase the risk of gestational hypertension. Gestational hypertension is high blood pressure that develops after 20 weeks of pregnancy and goes away after delivery.

Correct Answer is C

Explanation

The correct answer is

C. It transports glucose from the bloodstream into the cells for energy production.

Insulin is a hormone that regulates the metabolism of carbohydrates, fats, and proteins.It promotes the absorption of glucose from the blood into cells, where it can be used for energy or stored as glycogen or fat.It also inhibits glucose production and secretion by the liver and stimulates lipogenesis and protein synthesis.Insulin is essential for cell metabolism and low insulin levels can cause catabolism of body fat.

A. It converts glucose into glycogen for storage in the liver and muscles.

This statement is partially true, but not the main role of insulin.

Insulin does stimulate the formation of glycogen from glucose in the liver and muscles, but this is not its primary function.Glycogen is a form of stored glucose that can be mobilized when blood glucose levels are low.Insulin also inhibits the breakdown of glycogen (glycogenolysis) and the synthesis of glucose from amino acids and fatty acids (gluconeogenesis) in the liver.

B. It breaks down glucose into carbon dioxide and water for excretion in the urine and lungs.

This statement is false.

Insulin does not break down glucose, but rather facilitates its uptake by cells.

Glucose is broken down by a process called glycolysis, which produces pyruvate and ATP (energy).

Pyruvate can then enter the Krebs cycle and the electron transport chain to produce more ATP, carbon dioxide and water.Carbon dioxide is exhaled by the lungs and water is excreted by the kidneys.

Insulin has no direct role in these processes.

D. It stimulates glucose synthesis from amino acids and fatty acids in the liver.

This statement is false.

Insulin does not stimulate glucose synthesis, but rather inhibits it.

Glucose synthesis from non-carbohydrate sources, such as amino acids and fatty acids, is called gluconeogenesis.

This process occurs mainly in the liver and is stimulated by glucagon, a hormone that opposes insulin.Gluconeogenesis helps to maintain blood glucose levels when dietary intake or glycogen stores are low.Insulin suppresses gluconeogenesis by inhibiting the enzymes involved in this pathway.

A. Every hour B. Every two hours C. Every four hours D. Every six hours

Correct Answer is A

Explanation

The correct answer is choice A. The nurse should monitor the woman’s blood glucose levels every hour during labor.This is because the goal of intrapartum insulin therapy is maternal and fetal euglycemia with a maternal glucose less than 90 mg/dL.Hourly blood glucose monitoring can help adjust the insulin infusion rate and prevent hypoglycemia or hyperglycemia.

Choice B is wrong because every two hours is not frequent enough to maintain optimal glucose control during labor.

Choice C is wrong because every four hours is too long to wait between blood glucose checks and could lead to complications.

Choice D is wrong because every six hours is even longer and more risky than choice C. Normal ranges for blood glucose levels during labor are between 4.0 and 6.0-7.0 mmol/L (72-108 mg/dL).Women with gestational diabetes who require less than 1.0 units/kg/d of insulin may not need intravenous insulin, but they still need to be monitored regularly.
