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 A
Explanation
Choice A rationale
Deep vein thrombosis (DVT) is a condition characterized by the formation of a blood clot in a deep vein, usually in the leg. One of the most common symptoms of DVT is swelling of the affected extremity. This occurs because the blood clot obstructs the flow of blood, causing fluid to build up in the tissues.
Choice B rationale
While redness can be a symptom of DVT, it is not typically confined to a small area. Instead, redness associated with DVT is usually more widespread and is often accompanied by other symptoms such as swelling and pain.
Choice C rationale
A cool, mottled extremity is not a typical symptom of DVT34. DVT usually causes the affected area to feel warmer than the surrounding areas due to inflammation caused by the blood clot.
Choice D rationale
The presence of bilateral peripheral pulses is not a specific finding for DVT34. In fact, the presence of strong peripheral pulses may suggest that blood flow is not significantly obstructed.
Correct Answer is D
Explanation
Choice A rationale
55-year-old woman with coronary artery disease. While patients with coronary artery disease often have multiple comorbidities and may be on medications that could interact with Penicillin G, there is no specific increased risk of adverse reactions to Penicillin G in this population.
Choice B rationale
21-year-old college senior who is being treated for Streptococcus. Penicillin G is often used to treat Streptococcus infections. There is no specific increased risk of adverse reactions in this population unless the patient has a known allergy to penicillins.
Choice C rationale
23-year-old woman who recently delivered and has mastitis. Penicillin G can be used to treat mastitis, an infection of the breast tissue that results in breast pain, swelling, warmth, and redness. There is no specific increased risk of adverse reactions in this population unless the patient has a known allergy to penicillins.
Choice D rationale
65-year-old man with dehydration. Dehydration can affect kidney function, and Penicillin G is excreted by the kidneys. Therefore, patients with dehydration or any other condition that reduces kidney function are at a higher risk of adverse reactions to Penicillin G3.
