A nurse is caring for a client whose throat culture is positive for group A streptococcus 24 hours after a rapid strep test (RST) was negative. Which of the following actions is the nurse's priority?

Choice A reason:
Ecchymosis, or bruising, of the surrounding skin is a common finding associated with fractures due to the trauma to blood vessels in the area. While it can indicate bleeding or injury, ecchymosis itself does not specifically indicate impaired venous return.

Choice B reason:
Acute pain is a typical symptom following a fracture and results from the injury to the bone and surrounding tissues. Pain is an expected finding and does not directly suggest an issue with venous return.

Choice C reason:
A bounding distal pulse may actually suggest increased arterial flow or could be a sign of other conditions such as high blood pressure or fever. It does not indicate impaired venous return, which is typically characterized by a lack of pulse or a very weak pulse.

Choice D reason:
Increasing edema, or swelling, in the affected arm is a sign of impaired venous return. When veins are unable to effectively return blood to the heart, fluid can accumulate in the tissues, leading to edema. In the context of a fracture, this could be due to compression or damage to the veins, which can impede blood flow and result in swelling.

Choice A reason:
Hypertension is not typically an early manifestation of fat embolism syndrome (FES). FES is more commonly associated with hypoxemia, which can lead to hypotension rather than hypertension².

Choice B reason:
While a swollen calf may indicate deep vein thrombosis, it is not an early sign of FES. FES primarily affects the lungs and neurological systems early on, rather than causing localized swelling such as in a calf².

Choice C reason:
Tachypnea, or rapid breathing, is indeed an early sign of FES. This symptom usually develops before others and is due to the fat globules causing respiratory distress by blocking the pulmonary microcirculation²³⁴.

Choice D reason:
Bradycardia, or a slower than normal heart rate, is not an early sign of FES. Instead, patients may experience tachycardia as a response to hypoxemia and respiratory distress².
