A nurse is assisting with the care of a school-age child who recently returned to the PACU following pin placement for a radial head fracture with casting. Which of the following findings should the nurse monitor when conducting a circulatory check for compartment syndrome?
Edema.
Mottling.
Urticaria.
Pulselessness.
The Correct Answer is D
Choice A rationale:
Edema. Edema, the accumulation of fluid in the tissues, is not the primary indicator of compartment syndrome. While edema can occur due to various reasons, it's not specific to compartment syndrome. Compartment syndrome primarily involves increased pressure within a closed space (muscle compartment), which can compromise blood circulation and nerve function.
Choice B rationale:
Mottling. Mottling refers to a patchy, bluish discoloration of the skin that occurs due to poor blood circulation and is often seen in critically ill patients. While it might indicate circulatory issues, it's not a direct sign of compartment syndrome. Compartment syndrome is more closely associated with symptoms such as severe pain, numbness, and decreased or absent pulses.
Choice C rationale:
Urticaria. Urticaria, also known as hives, is a skin rash characterized by raised, itchy, and red or white welts. It is typically caused by an allergic reaction or other factors such as medications. Urticaria is unrelated to compartment syndrome, which involves the compression of nerves and blood vessels within a closed anatomical compartment, leading to ischemia and potential tissue damage.
Choice D rationale:
Pulselessness. Pulselessness is a critical sign that the nurse should monitor when conducting a circulatory check for compartment syndrome. Compartment syndrome occurs when there is increased pressure within a confined space (muscle compartment), leading to compromised blood flow and oxygen delivery to the tissues. The lack of a palpable pulse in the affected area suggests that blood flow is severely compromised. This is a late sign of compartment syndrome and requires immediate intervention to prevent tissue necrosis and long-term complications.

Correct Answer is B
Explanation
Choice A rationale:
Urine osmolality 500 mOsm/kg. Urine osmolality is a measure of urine concentration and is not a reliable indicator of infection. It reflects the kidney's ability to concentrate urine and can vary based on hydration status and other factors. An elevated urine osmolality could suggest dehydration, not necessarily infection.
Choice B rationale:
WBC 17,500/mm3. This is the correct choice. An elevated white blood cell count (WBC) is a hallmark sign of infection. The body's immune response to an infection often includes an increase in WBC count, particularly the neutrophil count. This elevation is known as leukocytosis and is a red flag for infection.
Choice C rationale:
BUN 12 mg/dL. Blood Urea Nitrogen (BUN) measures kidney function and hydration status. While an elevated BUN can indicate dehydration, it is not a specific marker for infection. BUN levels can be influenced by various factors, including diet and renal function.
Choice D rationale:
Urine specific gravity 1.014. Urine-specific gravity reflects the concentration of solutes in urine and the kidney's ability to concentrate or dilute urine. While changes in urine specific gravity can indicate dehydration or overhydration, it is not a direct indicator of infection. An infection is better detected through changes in WBC count and other clinical signs.
Correct Answer is A
Explanation
Choice A rationale:
A positive leukocyte esterase test indicates the presence of white blood cells (leukocytes) in the urine, which can be an indicator of a urinary tract infection (UTI). White blood cells are part of the body's immune response and their presence in the urine suggests inflammation and infection in the urinary tract.
Choice B rationale:
Deep gold-colored urine is not typically associated with a urinary tract infection. Normally, urine color can vary based on hydration, diet, and other factors, but color alone is not a reliable indicator of a UTI.
Choice C rationale:
The osmolality of 700 mOsm/L is not a specific finding related to urinary tract infections. Osmolality measures the concentration of particles in the urine and can vary based on hydration status. While it might be elevated in a concentrated urine sample, it is not a direct indicator of a UTI.
Choice D rationale:
A specific gravity of 1.015 is within the normal range and does not necessarily indicate a urinary tract infection. Specific gravity measures the concentration of solutes in the urine and can be influenced by hydration levels and kidney function. A UTI would primarily be indicated by the presence of white blood cells and other signs of infection in the urine.
