Advanced signs of a potentially life-threatening kidney injury include which of the following?

• A. Pain in the low back, blood in urine, burning while urinating, nausea, abdominal swelling, and vomiting
• B. Headache and dizziness only
• C. Rash and itching
• D. Cough and sore throat

Answer: (A)

Advanced signs of a potentially life-threatening kidney injury involve symptoms that point to serious kidney or urinary tract involvement and possible internal bleeding. Pain in the lower back or flank localizes to the kidneys, while blood in the urine is a direct sign that the kidneys or urinary tract are affected. Nausea and vomiting can accompany intense pain or bleeding, signaling a systemic response to a serious injury. Abdominal swelling can indicate internal bleeding or a developing hematoma around the kidneys, heightening concern for a more severe injury. The inclusion of burning with urination suggests urinary tract irritation or involvement, which can accompany kidney issues in this context.

The other options don’t present this combination of kidney-related symptoms. Headache and dizziness alone are nonspecific, rash and itching point to allergic or dermatologic issues, and cough with sore throat are respiratory symptoms. Together, the signs listed in this scenario best align with a serious kidney injury requiring prompt evaluation.
