Question 1

Phil has type 1 diabetes and gives himself insulin injections to help manage his blood glucose level.One afternoon,Phil tested his blood and discovered that his blood glucose level was 60 mg/dl.Based on this information,Phil should

Accepted Answer

A blood glucose level of 60 mg/dl is considered low (normal range is typically 70-130 mg/dl) and can lead to symptoms such as shakiness, sweating, confusion, and even seizures if not addressed. Consuming 15 grams of glucose in a pill or gel is recommended to raise his blood glucose level to a safe level. Giving himself an extra injection of insulin would lower his blood glucose level even further, which is not appropriate in this situation. Doing nothing or not eating anything for 5 hours can exacerbate the low blood glucose level and cause further harm.

Question 2

Which of the following foods has a high glycemic index (70 or more)?

Accepted Answer

Baked potatoes have a high glycemic index, typically above 70, meaning they can cause a rapid increase in blood sugar levels.

Question 3

Which of the following substances is a sugar that contributes to the sweetness of honey?

Accepted Answer

Fructose is a common monosaccharide sugar found in many plants, including nectar. It is the main sugar found in honey and gives it its sweet taste. Ribose is a sugar found in RNA, lactose is a sugar found in milk, and molasses is a byproduct of sugar production and contains a mixture of different sugars.

Question 4

Which of the following foods has a high glycemic index but a low glycemic load?

Accepted Answer

Plain microwave popcorn has a high glycemic index, which means it can cause a rapid increase in blood sugar levels. However, because it is relatively low in carbohydrates per serving, its glycemic load, which takes into account both the glycemic index and the carbohydrate content per serving, is low. This means it has a lesser impact on blood sugar levels when consumed in typical portions compared to foods with a high glycemic load.

Question 5

Table sugar is nearly _____ carbohydrate.

Accepted Answer

Table sugar, or sucrose, is almost entirely composed of carbohydrate, with a purity that can exceed 99%.

Question 6

Betty is constipated; she generally has bowel movements only twice a week.To help relieve her constipation without taking medications,Betty should

Accepted Answer

Increasing fiber intake can help add bulk to the stools and promote regular bowel movements. Restricting fluid intake or reducing intake of fruits and vegetables can potentially make constipation worse. Using colon cleansing enemas daily is not recommended as it can lead to dependence and disrupt the natural balance of the bowels.

Question 8

Mark has type 2 diabetes.For the past two weeks,his fasting blood glucose level has been below 130 mg/dl.Today,Mark's physician tested his blood.Although the fasting value was 125 mg/dl,she reported that he needs to do a better job of controlling his blood glucose level.Why would the physician make such a recommendation to Mark?

Accepted Answer

The physician may have looked at Mark's HbA1c level, which is a measure of average blood glucose over the past 2-3 months. Even if Mark's fasting blood glucose values were within target range for the past two weeks, a high HbA1c level would indicate that his overall blood glucose control needs improvement.

Question 9

Which of the following foods has a low glycemic index (less than 70)?

Accepted Answer

Raw apple has a low glycemic index of less than 70. Cornflakes cereal and jelly beans have high glycemic indices, and popcorn, while a relatively healthy snack, can have a medium to high glycemic index depending on how it is prepared and served.

Question 10

Question 14

Erika has type 1 diabetes and gives herself insulin injections to help manage her blood glucose level.One afternoon,Erika tested her blood and discovered that her blood glucose level was 260 mg/dl.Based on this information,Erika should

Accepted Answer

Based on Erika's high blood glucose level of 260 mg/dl, she should give herself a specific dose of insulin. Insulin helps to lower blood glucose levels and is necessary for individuals with type 1 diabetes to manage their condition effectively. Consuming candy or fruit juice would only increase Erika's blood glucose level further, and taking a dietary supplement containing vitamin C would not affect her blood glucose level. Doing nothing to intervene and leave her blood glucose level elevated can lead to long-term complications of diabetes such as kidney, eye, and nerve damage.

Question 15

Anna has type 1 diabetes and gives herself insulin injections to help manage her blood glucose level.One morning,Anna tested her blood before she ate breakfast and discovered that her blood glucose level was 88 mg/dl.Based on this information,Anna should

Accepted Answer

Anna's fasting blood glucose level of 88 mg/dl is within the target range for individuals with type 1 diabetes. Therefore, she does not need to consume any extra sugar or give herself an extra injection of insulin. It is also not recommended for her to skip breakfast or not eat for the next 5 hours, as this could lead to low blood sugar levels. Anna should continue with her normal routine and monitor her blood sugar levels regularly.

Question 16

Jamie has a tumor that affects the functioning of her beta cells.Based on this information,Jamie's

Accepted Answer

Beta cells are responsible for producing insulin, which regulates blood glucose levels. If Jamie's beta cells are affected by the tumor, it is likely that her blood glucose level is difficult to regulate.
