Question 1

Obesity is identified using what measurement?

Accepted Answer

Obesity is commonly identified using the Body Mass Index (BMI), which is a measure of body fat based on height and weight.

Question 2

What lab test, often deemed the "lie detector test" by health care workers, measures the average blood glucose levels for the past 2 -3 months?

Accepted Answer

The Hemoglobin A1c test, often referred to as HbA1c, measures the average blood glucose levels over the past 2-3 months, acting as a long-term indicator of blood sugar control.

Question 3

The feedback loop involving luteinizing hormone and estrogen is terminated by

Accepted Answer

Ovulation leads to a decrease in estrogen secretion, which in turn reduces the stimulation of luteinizing hormone (LH) secretion, thus terminating the feedback loop.

Question 4

What cells secrete insulin?

Accepted Answer

Beta cells of the pancreas are responsible for the secretion of insulin, which helps regulate blood glucose levels.

Question 5

Which of the following is an example of negative feedback?

Accepted Answer

E) describes a classic example of negative feedback where the body detects an increase in blood pressure and responds by initiating mechanisms to lower it back to normal, thus negating the initial stimulus.

Question 6

Luteinizing hormone -mediated regulation of estrogen during ovulation in women is an example of

Accepted Answer

The answer of Luteinizing hormone -mediated regulation of estrogen during...

Question 7

John has type 2 diabetes. He has a sedentary lifestyle, is overweight, and recently went to the doctor who gave him a hemoglobin A_1ctest which came back at 7%. What is the best course of treatment for John?

Accepted Answer

John's hemoglobin A1c level of 7% indicates that his diabetes is not well-controlled. A combination of a strict diet, exercise, frequent monitoring, and oral glucose medication is typically recommended for managing type 2 diabetes, especially when lifestyle changes alone are insufficient.

Question 8

The process of maintaining the internal environment in a state compatible for life is called __________, and it occurs primarily through __________.

Accepted Answer

Homeostasis is the process by which organisms maintain a stable internal environment, and it primarily occurs through mechanisms of negative feedback, which help to counteract changes that deviate from the norm.

Question 9

Approximately what percentage of people living in the United States suffers from diabetes mellitus?

Accepted Answer

According to data from the Centers for Disease Control and Prevention (CDC), approximately 10.5% of the U.S. population had diabetes in 2020. The closest option to this percentage is 8%.

Question 10

Although diabetes mellitus has many symptoms, the primary diagnostic symptoms of the disease are ___________ and ___________ .

Accepted Answer

The primary diagnostic symptoms of diabetes mellitus are elevated blood glucose levels and the presence of glucose in the urine. These symptoms are direct consequences of the body's inability to properly use or produce insulin, leading to high blood sugar levels that the body tries to eliminate through the urine.

Question 11

What is the difference between diabetes mellitus and diabetes insipidus?

Accepted Answer

Diabetes mellitus is characterized by a deficit in insulin activity (either due to lack of insulin secretion or resistance to insulin), leading to high blood sugar levels. Diabetes insipidus, on the other hand, involves a deficit in the activity of antidiuretic hormone (ADH), which leads to excessive urination and thirst due to the body's inability to concentrate urine.

Question 12

Prediabetics have a fasting blood glucose level of __________and, according to the Centers for Disease Control (CDC), approximately__________million Americans are prediabetic.

Accepted Answer

Prediabetics have a fasting blood glucose level of 100 -125 mg/dL, and according to the CDC, approximately 80 million Americans are prediabetic.

Question 13

What are the two major consequences for those who suffer from diabetes mellitus?

Accepted Answer

Diabetes mellitus is characterized by high blood glucose levels because the body either doesn't produce enough insulin or cannot effectively use the insulin it produces, leading to cells being unable to utilize glucose for energy.

Question 14

What is the primary reason the prevalence of diabetes is increasing in the U.S. population?

Accepted Answer

The answer of What is the primary reason the prevalence...

Question 15

What percentage of women will develop type 2 diabetes after developing gestational diabetes?

Accepted Answer

The answer of What percentage of women will develop type...

Question 16

Which of the following types of diabetes mellitus was formerly referred to as insulin -dependent or juvenile -onset diabetes mellitus?

Accepted Answer

Type 1 diabetes mellitus was formerly known as insulin-dependent or juvenile-onset diabetes, as it often presents in children and young adults and requires insulin treatment.

Question 17

A patient has a high salt or sodium intake which draws fluid out of his cells to dilute the sodium. This process occurs as a result of

Accepted Answer

The process described is an example of negative feedback control, where the body responds to an increase in sodium concentration (stimulus) by moving fluid out of cells to dilute the sodium, aiming to bring the system back to its set point or normal level.

Question 18

Which of the following people would be more prone to develop diabetes mellitus type II?

Accepted Answer

Obesity is a significant risk factor for the development of type II diabetes, and certain ethnic groups, including Hispanics, have a higher predisposition to develop this condition. Therefore, an obese Hispanic adult would be more prone to develop diabetes mellitus type II compared to the other options provided.

Question 19

What percentage of adults in the United States is obese?

Accepted Answer

As of my last update in 2023, approximately 35% of adults in the United States are considered obese. This percentage reflects a significant public health concern, indicating a high prevalence of obesity in the adult population.

Question 20

Which of the following is a normal blood glucose level?

Accepted Answer

A normal blood glucose level is typically around 70 to 99 mg/dL when fasting, and less than 140 mg/dL two hours after eating. Therefore, 100 mg/dL is within a normal range, making option A correct.
