A nurse is preparing to instill an otic suspension into an adult client's ear.

Which of the following methods should the nurse plan to use?

Compartment syndrome occurs when there is increased pressure within a closed muscle compartment, leading to reduced blood flow to the muscles and nerves in that compartment. In this case, the open fracture and subsequent reduction and stabilization procedure can cause swelling and increased pressure within the affected compartment. This can impede blood flow and potentially lead to tissue damage. Common symptoms include severe pain, swelling, numbness, and decreased or absent pulses. Immediate medical attention is necessary if compartment syndrome is suspected.

Deep Vein Thrombosis (DVT) refers to the formation of blood clots within the deep veins, typically in the lower extremities. In the case of a client with an open fracture and immobilization with a splint, the risk of DVT increases due to factors such as reduced mobility, injury to blood vessels, and blood stasis. DVT can lead to serious complications if a clot dislodges and travels to the lungs, causing a pulmonary embolism. Symptoms of DVT may include pain, swelling, warmth, and redness in the affected limb.

While osteomyelitis and fat embolism syndrome can occur as complications of long bone fractures, they are not explicitly mentioned in the given scenario. Osteomyelitis refers to an infection in the bone, which can develop if bacteria enter an open fracture. Fat embolism syndrome can occur when fat globules from the bone marrow enter the bloodstream, usually following a long bone fracture.

Answer: A. Potassium

Rationale:

A) Potassium:

Furosemide is a loop diuretic that can cause significant potassium loss through increased urine output. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to serious cardiac arrhythmias and muscle weakness. Ensuring potassium levels remain within a normal range helps maintain the infant's overall health and safety while on this medication.

B) WBC Count:

While it is important to monitor WBC count in various clinical situations, furosemide does not typically affect white blood cell levels. Therefore, monitoring WBC count is not specifically indicated for infants receiving furosemide unless there is another underlying condition that requires it.

C) Iron:

Iron levels are not typically affected by furosemide. Monitoring iron levels would be more relevant in cases of anemia or other hematologic conditions. Furosemide does not interfere with iron metabolism, so this test is not a priority for infants on this medication.

D) Amylase:

Amylase is an enzyme related to the pancreas and is typically monitored in conditions such as pancreatitis. Furosemide does not have a direct effect on amylase levels, so monitoring this enzyme is not necessary for infants receiving this diuretic. The focus should be on electrolytes, particularly potassium.
