Question 1

When classifying blood pressure in the pediatric population,the same cut-points are used as when classifying the blood pressure of adults.

Accepted Answer

The cut-points used to classify blood pressure in children and adolescents are based on age, sex, and height percentiles, and are not the same as those used for adults.

Question 2

Although precision is necessary in order for accuracy to exist,accuracy is not necessary in order for precision to exist.

Accepted Answer

Precision refers to the degree of consistency and exactness, while accuracy refers to the degree of correctness or truthfulness. Therefore, precision can exist independently of accuracy, as long as there is consistency and exactness in the measurements or calculations. However, accuracy cannot exist without precision, as there must be some level of consistency in order to determine whether the result is correct or not.

Question 3

An A1C level of _______% and higher is a risk factor for diabetes.

Accepted Answer

An A1C level of 5.7% and higher is considered a risk factor for diabetes, indicating prediabetes or diabetes when it reaches or exceeds this threshold.

Question 4

Asymptomatic adults should be screened for prediabetes or diabetes mellitus starting at age ________ years.

Accepted Answer

Asymptomatic adults should start being screened for prediabetes or diabetes mellitus at age 45 years, according to guidelines from various health organizations. This recommendation is based on the increasing risk of diabetes with age and the potential for early intervention to prevent complications.

Question 5

Because cholesterol and triglycerides are fat soluble,they must be transported in the blood by spherical macromolecular complexes known as __________.

Accepted Answer

The answer of Because cholesterol and triglycerides are fat soluble,they...

Question 6

The American Diabetes Association has several medical nutrition therapy recommendations for adults with diabetes.Which one of the following is NOT on this list?

Accepted Answer

The American Diabetes Association recommends limiting alcohol intake and avoiding sugary beverages, but moderate consumption of alcoholic beverages (such as one drink per day for women and two drinks per day for men) can be incorporated into a healthy eating plan for those with diabetes. Nonnutritive sweeteners can also be used in moderation. Therefore, option C is not on the list of recommendations.

Question 7

Children who are overweight and have two or more risk factors should be screened for diabetes mellitus starting at age ________ years.

Accepted Answer

Children who are overweight and have two or more risk factors should be screened for diabetes mellitus starting at age 10 years, according to the American Diabetes Association guidelines. Screening should be repeated every three years if results are normal, and more frequently if results are abnormal.

Question 8

Diabetes that develops during pregnancy is known as ________.

Accepted Answer

The answer of Diabetes that develops during pregnancy is known...

Question 9

One of the advantages of using non-HDL-cholesterol as an indicator of CHD risk is that it can be accurately determined in the non-fasting state.

Accepted Answer

Non-HDL cholesterol includes all the atherogenic lipoproteins and its measurement does not require fasting. This makes it convenient to obtain in routine clinical practice.

Question 10

Glycosylated hemoglobin is considered a good indicator of average blood glucose levels during the previous 8 to 12 weeks.

Accepted Answer

Hemoglobin A1c (HbA1c), which is also called glycosylated hemoglobin, reflects an average blood glucose (sugar) level over the previous 2 to 3 months. This is because red blood cells live for about 3 months, and the HbA1c test measures the percentage of hemoglobin that has glucose attached to it during that lifespan. Therefore, HbA1c is an important tool for managing diabetes and assessing blood sugar control over time.

Question 11

Diastole refers to the phase of cardiac relaxation.

Accepted Answer

Diastole is the phase of cardiac cycle where the heart muscle relaxes and fills with blood.

Question 12

Risk factor intervention efforts that are implemented before a certain risk factor even develops are known as ________ prevention.

Accepted Answer

The answer of Risk factor intervention efforts that are implemented...

Question 13

Type 2 diabetes is rarely diagnosed in individuals younger than 30 years of age.

Accepted Answer

Although type 2 diabetes is more commonly diagnosed in adults over 40 years of age, it can occur at any age including in children and young adults.

Question 14

Current clinical practice guidelines developed by the U.S.National Heart,Lung,and Blood Institute for preventing cardiovascular disease in children and adolescents do not recommend universal screening of lipid levels in children and adolescents.

Accepted Answer

The current clinical practice guidelines developed by the U.S. National Heart, Lung, and Blood Institute do recommend universal lipid screening for children and adolescents at specific ages (once between the ages of 9 and 11 and again between 17 and 21) to better identify those at risk for cardiovascular disease.

Question 15

Individuals at increased risk of developing diabetes in the future because they have either impaired fasting glucose or impaired glucose tolerance are said to have ________.

Accepted Answer

The answer of Individuals at increased risk of developing diabetes...

Question 16

The majority of within-individual variability in cholesterol analyses is due to preanalytical factors.

Accepted Answer

Preanalytical factors such as fasting status, timing of sample collection, and sample handling and transportation can significantly impact cholesterol measurements within an individual over time.
