The nurse is teaching an adult patient with Type 1 diabetes that a primary cause of the development of diabetic ketoacidosis (DKA) is:
Omitted meals
Polydipsia and polyphagia
Not taking enough insulin
An insulin overdose
The Correct Answer is C
Choice A rationale
Omitted meals can lead to hypoglycemia, not diabetic ketoacidosis (DKA). DKA is caused by a lack of insulin, not a lack of food intake.
Choice B rationale
Polydipsia and polyphagia are symptoms of hyperglycemia, not causes of DKA. They occur as the body tries to compensate for high blood sugar levels.
Choice C rationale
Not taking enough insulin is a primary cause of the development of DKA. Without enough insulin, the body begins to break down fat for fuel, which produces acids known as ketones.
Choice D rationale
An insulin overdose would lead to hypoglycemia, not DKA. DKA is caused by a lack of insulin, not an excess.

Correct Answer is D
Explanation
Choice A rationale
The infectious agent is the pathogen that causes the disease, and the reservoir is where the infectious agent lives and multiplies. Hand washing does not directly intervene between these two links.
Choice B rationale
The mode of transmission is how the infectious agent travels to other people and places, and the portal of entry is the route by which an infectious agent enters a new host. Hand washing does not directly intervene between these two links.
Choice C rationale
The susceptible host is a person who is vulnerable to the disease, and the infectious agent is the pathogen that causes the disease. Hand washing does not directly intervene between these two links.
Choice D rationale
The portal of exit is the route by which an infectious agent escapes or leaves the reservoir, and the mode of transmission is how the infectious agent travels to other people and places. Hand washing directly intervenes between these two links by removing the infectious agent from the hands (portal of exit) and preventing its transmission to other people or surfaces.
Correct Answer is ["A","B","D"]
Explanation
Choice A rationale
Rotating injection sites when administering insulin glargine is important to prevent lipodystrophy, a condition that can affect insulin absorption.
Choice B rationale
Insulin glargine has no peak of action, which reduces the risk of hypoglycemia. This is a key feature of long-acting insulins like glargine.
Choice C rationale
Food does not need to be consumed within 30 minutes after injection of insulin glargine. This is a characteristic of rapid-acting insulins, not long-acting insulins like glargine.
Choice D rationale
Checking for microalbuminuria if blood glucose levels are above 280 mg/dL is a good practice. Microalbuminuria can be an early sign of kidney damage, which can occur with poorly controlled diabetes.
