Question 1

Josie has just been diagnosed with Type 1 diabetes.Diabetes therapy with insulin focuses initially on controlling fasting plasma glucose with the use of a long-acting insulin analog such as .

Accepted Answer

Lantus is a long-acting insulin analog commonly used for controlling fasting plasma glucose in Type 1 diabetes therapy. Novolog and Humulin R are rapid-acting insulin analogs used for controlling postprandial glucose levels, while Humulin N is an intermediate-acting insulin analog.

Question 2

Skylar's illness is in remission and she has been told she no longer needs to take prednisone.How should the prednisone be discontinued?

Accepted Answer

Prednisone should be gradually tapered down to avoid withdrawal symptoms and to allow the body to adjust to the change in medication. Suddenly discontinuing the drug can cause complications such as adrenal insufficiency. Therefore, the best choice would be to gradually taper down the prednisone dose.

Question 3

Erika will be taking corticosteroids for a relatively long period of time.In order to reduce the risk of suppressing her adrenals and causing adrenal atrophy,what type of corticosteroids are most effective?

Accepted Answer

D

Question 4

Danika has Type 1 diabetes and must take a rapid-acting insulin to reduce post-meal hyperglycemia.This is called a ____.

Accepted Answer

A prandial dose is a rapid-acting insulin injection taken before meals by people with Type 1 diabetes to reduce post-meal hyperglycemia. A corrective dose is taken to bring down high blood sugar levels, while glargine is a long-acting insulin used to maintain baseline blood sugar levels. Combination doses involve taking both short-acting and long-acting insulin injections at different times throughout the day.

Question 5

Karla knows that when her friend took thyroid replacement,her friend lost weight.Karla has normal levels of thyroid hormones,but wonders whether taking thyroid replacement would help her lose weight as well.What should you tell her?

Accepted Answer

Taking thyroid replacement when not medically necessary can be dangerous and ineffective for weight loss. It can cause hyperthyroidism, which can lead to heart problems, shaky hands, and weight loss that may not be sustainable. Additionally, it can interfere with other medications and can cause long-term damage to the thyroid gland, leading to permanent hypothyroidism. Therefore, it is not recommended to take thyroid replacement solely for the purpose of weight loss.

Question 6

Erika has had a kidney transplant and is taking,among her many medications,corticosteroids.The corticosteroids are intended to .

Accepted Answer

Corticosteroids are used as immunosuppressive medications to prevent the body from rejecting the transplanted kidney. They work by reducing the activity of the immune system, which would otherwise recognize the transplanted kidney as foreign and attack it.

Question 7

Lauri is being treated for hypothyroidism with a synthetic replacement.What signs might indicate that her dose is too high?

Accepted Answer

A high dose of synthetic thyroid hormone can lead to symptoms of hyperthyroidism, such as exophthalmos (bulging eyes), which is associated with an overactive thyroid.

Question 8

Phebian takes rosiglitazone for his Type 2 diabetes.How does rosiglitazone act?

Accepted Answer

Rosiglitazone works by decreasing insulin resistance and improving the body's sensitivity to insulin, which helps control blood sugar levels in Type 2 diabetes.

Question 9

Bennie has hyperthyroidism due to Grave's disease.What is his likely course of treatment?

Accepted Answer

The standard treatment for hyperthyroidism due to Grave's disease is the use of antithyroid agents to control symptoms followed by treatment with radioactive iodine to reduce the size of the thyroid gland and decrease thyroid hormone production. In some cases, surgical removal of the thyroid may be necessary if other treatments are not effective, but this is usually reserved for cases where the patient cannot tolerate antithyroid agents or radioactive iodine. Therefore, options B and C are unlikely to be the best course of treatment. Option D is also incorrect since surgery is usually not the first line of treatment for hyperthyroidism.

Question 10

Three-year-old Wiley is small for his age;testing reveals that he has very low levels of human growth hormone.What gland produces human growth hormone?

Accepted Answer

The pituitary gland produces human growth hormone, which is responsible for growth and development.

Question 11

Nasir's acute flare-up of ulcerative colitis is being treated with corticosteroids.Why are corticosteroids recommended for only brief treatment of ulcerative colitis flare-ups?

Accepted Answer

The answer of Nasir's acute flare-up of ulcerative colitis is...

Question 12

Routine newborn testing reveals that Kassandra has congenital hypothyroidism.If congenital hypothyroidism is untreated,Kassandra might develop .

Accepted Answer

Untreated congenital hypothyroidism can lead to cognitive disabilities, as thyroid hormones are critical for brain development and function. While hearing and vision loss can occur in some cases, cognitive disabilities are a more common consequence of untreated hypothyroidism. Hyperactivity disorder is not typically associated with hypothyroidism.

Question 13

Your friend Kaylin has been diagnosed with Type 1 diabetes and you take part in her diabetes education classes to learn more.What symptoms might indicate that Kaylin is hyperglycemic?

Accepted Answer

Fruity breath is a symptom of hyperglycemia in diabetic patients, indicating that the body is burning fat instead of glucose for energy. A, B, and C are symptoms of hypoglycemia, which is low blood sugar, not hyperglycemia.

Question 14

Ayla has a severe allergic reaction and is treated with corticosteroids.What gland produces corticosteroids?

Accepted Answer

Corticosteroids are hormones produced by the adrenal gland. They are often used in the treatment of allergic reactions and other inflammatory conditions. The pituitary gland produces other hormones such as growth hormone and thyroid-stimulating hormone, while the islets of Langerhans in the pancreas produce insulin and glucagon to regulate blood sugar levels. The thyroid gland produces thyroid hormone to regulate metabolism.

Question 15

Martina is being treated for hypothyroidism with a synthetic T4 replacement.What is the advantage of this approach?

Accepted Answer

The answer of Martina is being treated for hypothyroidism with...

Question 16

Freya takes glipizide for Type 2 diabetes.To what class does this drug belong?

Accepted Answer

Glipizide belongs to the class of drugs known as sulfonylureas, which work by stimulating the release of insulin from the pancreas, thereby decreasing blood glucose levels.

Question 17

Cornelius is experiencing severe pain in his knees associated with rheumatoid arthritis.He and his doctor are discussing corticosteroid therapy.What administration route is most likely?

Accepted Answer

Injection into the joint is the most appropriate route for corticosteroid therapy in cases of severe pain associated with rheumatoid arthritis as it provides targeted relief to the affected area. IM injection and oral administration have a systemic effect and can have more side effects, while topical administration may not be effective for deeper joint pain.

Question 18

Your friend Kaylin,who has Type 1 diabetes,shows signs of hypoglycemia,although she is still conscious.What should you do?

Accepted Answer

Giving Kaylin a source of fast-acting carbohydrates, such as orange juice, candy, honey, or syrup, can help raise her blood glucose levels quickly. Afterward, a high protein snack like peanut butter or milk can help stabilize her blood sugar. This treatment is recommended by the American Diabetes Association for managing hypoglycemia. It is important to note that administering insulin would lower Kaylin's blood glucose levels further and should not be done in this situation. Additionally, administering glucose solution via IM injection is not recommended and should only be done by trained medical professionals.

Question 19

Clara has been diagnosed with Type 2 diabetes and is being started on an oral antidiabetic agent.What biguanide might she be given?

Accepted Answer

Metformin is a commonly used biguanide for the treatment of Type 2 diabetes. It works by reducing glucose production in the liver and increasing insulin sensitivity. Acarbose is an alpha-glucosidase inhibitor, glipizide is a sulfonylurea, and exenatide is a glucagon-like peptide-1 (GLP-1) receptor agonist, which are all different classes of antidiabetic medications.

Question 20

Elisha has Type 1 diabetes and uses an analog insulin.What is an advantage of analog insulin?

Accepted Answer

Analog insulins are designed to more closely mimic the body's natural insulin release patterns, which can lead to a decreased risk of hypoglycemia compared to older, human insulins. This is because their action profiles can be matched more closely to the body's insulin needs, reducing the likelihood of blood sugar levels falling too low.
