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.

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.
