A nurse is collecting data from a client who has diabetes mellitus.
Which of the following findings indicates that the client is experiencing DKA?

Choice A rationale:

Shortness of breath is a common symptom of a hypersensitivity reaction. This occurs because the body’s immune system responds to a foreign substance, known as an antigen, by producing specific antibodies. This immune response can cause inflammation and swelling in various parts of the body, including the airways, leading to shortness of breath.

Choice B rationale:

A black hairy tongue is not typically associated with a hypersensitivity reaction. It is a condition that causes the tongue to appear black and hairy, and it’s usually caused by an overgrowth of bacteria or yeast on the tongue. It’s not related to allergies or hypersensitivity reactions.

Choice C rationale:

Itching is another common symptom of a hypersensitivity reaction. When the body encounters an antigen, it triggers an immune response that releases chemicals like histamine. Histamine can cause itching, among other symptoms.

Choice D rationale:

Swelling of the tongue can be a symptom of a severe hypersensitivity reaction known as anaphylaxis. This is a medical emergency that requires immediate attention. The swelling is caused by inflammation in response to an antigen.

Choice E rationale:

Wheezing is a symptom of a hypersensitivity reaction, specifically type I hypersensitivity. This type of reaction includes allergic disorders, which affect the lungs among other parts of the body. The immune response to an antigen can cause the airways to narrow and produce a wheezing sound.

Choice A rationale:

Sodium levels in the blood are typically between 135 and 145 milliequivalents per liter (mEq/L). A sodium level of 140 mEq/L falls within this range, indicating normal sodium levels. Sodium plays a key role in your body. It helps maintain normal blood pressure, supports the work of your nerves and muscles, and regulates your body’s fluid balance. A normal sodium level is therefore crucial for the body’s overall function.

Choice B rationale:

A glucose level of 120 mg/dL is considered normal for a fasting blood sugar test. Glucose is your body’s main source of energy. It comes from the food you eat and is carried through your bloodstream to the cells of your body. If the glucose level in the blood is too high or too low, it can indicate a medical condition such as diabetes.

Choice C rationale:

Potassium levels in the blood are typically between 3.6 and 5.2 millimoles per liter (mmol/L). A potassium level of 4.5 mEq/L falls within this range, indicating normal potassium levels. Potassium is a type of electrolyte that is vital to the function of nerve and muscle cells, including those in your heart. Your blood potassium level is normally 3.6 to 5.2 millimoles per liter (mmol/L). Having a blood potassium level higher than 6.0 mmol/L can be dangerous and usually requires immediate treatment.

Choice D rationale:

The Blood Urea Nitrogen (BUN) test is a routine test used to assess kidney function. Urea nitrogen is a waste product that’s created in your liver when the body breaks down proteins. Healthy kidneys filter urea nitrogen from your blood, but when your kidneys aren’t working well, the BUN level rises. The normal range for BUN is typically around 7-20 mg/dL2. A BUN level of 55 mg/dL is significantly higher than the normal range, indicating that the kidneys may not be functioning properly. This is a critical finding that should be reported to the provider before initiating the medication amphotericin B. Amphotericin B is an antifungal medication used to treat serious, life-threatening fungal infections. However, it is known for its severe and potentially lethal side effects, including kidney damage. Therefore, a high BUN level should be reported to the provider before initiating this medication.
