In adrenocortical insufficiencies, such as Addison’s disease, what causes the most severe manifestations?
An insufficient amount of triiodothyronine (T3) and thyroxine (T4)
Decreased levels of all the adrenocortical hormones
Deficiencies in the renin-angiotensin system
An insufficient amount of circulating cortisol
The Correct Answer is D
Choice A rationale
An insufficient amount of triiodothyronine (T3) and thyroxine (T4) would lead to hypothyroidism, not Addison’s disease.
Choice B rationale
Decreased levels of all the adrenocortical hormones could lead to various symptoms, but the most severe manifestations of Addison’s disease are specifically caused by an insufficient amount of circulating cortisol.
Choice C rationale
Deficiencies in the renin-angiotensin system could affect blood pressure regulation, but they would not cause the most severe manifestations of Addison’s disease.
Choice D rationale
An insufficient amount of circulating cortisol is indeed what causes the most severe manifestations of Addison’s disease. Cortisol is a hormone that helps your body respond to stress, including the stress of illness, injury or surgery. It also helps maintain your blood pressure, heart function, immune system and blood glucose (sugar) levels.

Correct Answer is C
Explanation
Choice A rationale
Hyperglycemic lipid syndrome is not a disorder related to breaking down fats for energy in clients with type 1 diabetes.
Choice B rationale
Lipidosis hyperosmolar ketosis is not a recognized medical condition.
Choice C rationale
Diabetic ketoacidosis (DKA) is a condition that can occur in clients with type 1 diabetes when the body starts breaking down fats for energy due to a lack of insulin.
Choice D rationale
Nonketotic hyperglycemic hyperosmolar syndrome (NHHS) is a serious condition that can occur in people with diabetes, particularly type 2, but it is not specifically related to the breakdown of fats for energy.
Correct Answer is C
Explanation
Choice A rationale
An exaggerated stress response in a client with type 1 diabetes would not cause higher blood sugar readings through the release of insulin. In fact, stress tends to increase blood sugar levels.
Choice B rationale
The release of glucocorticoids during stress does not typically cause lower blood sugar readings. Glucocorticoids tend to raise blood sugar levels.
Choice C rationale
An exaggerated stress response can cause higher blood sugar readings through the release of glucocorticoids. Stress hormones like glucocorticoids interfere with insulin’s ability to move glucose from the blood into the cells, leading to an increase in blood sugar levels.
Choice D rationale
An exaggerated stress response would not cause lower blood sugar readings through the release of insulin. Stress typically raises, not lowers, blood sugar levels.
