The nurse is aware that the diagnostic level of a fasting blood glucose for a client with diabetes is:
135 mg/dL of glucose.
140 mg/dL of glucose.
126 mg/dL of glucose.
145 mg/dL of glucose.
The Correct Answer is C
Choice A rationale
A fasting blood glucose level of 135 mg/dL is above the diagnostic threshold for diabetes. However, it is not the exact threshold value.
Choice B rationale
A fasting blood glucose level of 140 mg/dL is significantly above the diagnostic threshold for diabetes.
Choice C rationale
A fasting blood glucose level of 126 mg/dL or higher on two separate tests indicates diabetes.
Choice D rationale
A fasting blood glucose level of 145 mg/dL is significantly above the diagnostic threshold for diabetes.

Correct Answer is ["A","B","E"]
Explanation
Choice A rationale
Proteins, vitamin C, and zinc are essential for wound healing. Proteins are the building blocks for body tissue, and zinc plays a role in protein synthesis. Vitamin C is needed for the formation of collagen, a protein used to make skin, scar tissue, and blood vessels.
Choice B rationale
Care should be taken when walking to avoid bumping the limb. Any trauma to the affected limb could potentially worsen the condition or delay healing.
Choice C rationale
Cleaning the ulcer with soap and water may not be the best option. Soap can be irritating to the skin and may delay healing. Instead, the ulcer should be cleaned as per healthcare provider’s instructions.
Choice D rationale
Cortisone cream is not typically used for venous stasis ulcers. It can thin the skin and delay healing.
Choice E rationale
Compression stockings are often recommended for patients with post-thrombotic syndrome. They can help reduce swelling and improve blood flow, which can promote healing of the venous stasis ulcer.
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.
