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 A
Explanation
Choice A rationale:
Pain following range-of-motion exercises is a significant finding that should be reported to the provider. It could indicate the possibility of complications, such as further injury or impaired healing. Adolescents with fractured bones are often encouraged to perform range-of-motion exercises to prevent stiffness and promote circulation. However, increased pain during or after these exercises could indicate problems like muscle strain or improper alignment of the fracture, which need to be addressed promptly.
Choice B rationale:
Pruritus (itching) under the cast is common and can be expected due to the accumulation of dead skin cells and sweat. While it can be uncomfortable for the client, it's not an urgent concern that requires immediate reporting to the provider. Strategies to alleviate itching, such as using a cool blow dryer under the cast, can be taught to the client.
Choice C rationale:
The presence of swelling while the extremity is dependent is a normal response to gravity and is not an alarming finding. Swelling when the extremity is dependent is expected, especially within the initial stages of fracture healing. It suggests that the blood supply is reaching the area for healing purposes. Elevation and rest can help reduce the swelling.
Choice D rationale:
Coolness of the toes could be due to reduced blood flow, but this finding alone may not be an immediate concern. It's essential to consider the client's overall circulation, capillary refill, and presence of pulses. If other signs of impaired circulation, such as pallor or delayed capillary refill, are present along with coolness, it might indicate compromised vascular supply. However, based on the information provided, this choice is not as urgent as reporting pain following range-of-motion exercises.
Correct Answer is D
Explanation
Choice A rationale:
Extremities warm to the touch. This manifestation is not indicative of decreased cardiac output. Warm extremities suggest adequate peripheral perfusion and circulation. In a child with decreased cardiac output, the body might attempt to shunt blood away from the extremities to prioritize vital organs, leading to cooler extremities.
Choice B rationale:
Capillary refill 2 seconds. A capillary refill time of 2 seconds is within the normal range for a preschool-aged child. This quick capillary refill suggests adequate circulation and is not a sign of decreased cardiac output. Prolonged capillary refill time might be indicative of poor peripheral perfusion.
Choice C rationale:
Blood pressure 112/66 mm Hg. While a blood pressure of 112/66 mm Hg might be within the normal range for a preschooler, it is not the most reliable indicator of decreased cardiac output. Blood pressure can be influenced by various factors, and a seemingly normal blood pressure does not rule out decreased cardiac output if other manifestations are present.
Choice D rationale:
Diminished pulses. This is the correct choice. Diminished or weak pulses are indicative of decreased cardiac output. Inadequate blood volume being pumped by the heart can lead to reduced peripheral perfusion, resulting in diminished pulses. This sign is important in assessing the child's cardiovascular status postoperatively, especially after a corrective procedure for tetralogy of Fallot.
