What characteristics describe an acute infection?
Symptoms occur in a confined specific location on the body.
Symptoms are severe, occur rapidly, but are short-lived.
Symptoms are not apparent and persist over a long period of time.
Symptoms are less severe and persist over a long period of time.
The Correct Answer is B
Choice A reason: Acute infections are not defined by location but by rapid onset and severity. While some infections may be localized, the hallmark is their abrupt, intense presentation, resolving quickly with treatment or spontaneously, making this choice incomplete and incorrect for fully describing acute infections.
Choice B reason: Acute infections are characterized by rapid onset, severe symptoms, and short duration, typically resolving within days to weeks. This reflects the body’s immediate immune response to pathogens, causing intense but transient symptoms, such as fever or pain, making this the correct choice.
Choice C reason: Non-apparent, prolonged symptoms describe subclinical or chronic infections, not acute ones. Acute infections present with noticeable, severe symptoms that resolve quickly, not persisting asymptomatically, making this choice incorrect for the characteristics of acute infections.
Choice D reason: Less severe, prolonged symptoms describe chronic infections, like tuberculosis, not acute infections. Acute infections feature rapid, intense symptoms that resolve quickly, not mild symptoms over time, making this choice incorrect for describing acute infections.

Correct Answer is A
Explanation
Choice A reason: Landing on the feet from a high fall causes axial loading, compressing the spinal column, often resulting in a compression injury to the spinal cord. This damages cord tissue, making this the correct choice.
Choice B reason: Transection involves complete severing of the spinal cord, typically from penetrating trauma. A fall causing compression is less likely to fully transect the cord, making this choice incorrect.
Choice C reason: Hyperflexion injuries occur when the spine bends forward excessively, as in whiplash. A fall on the feet causes vertical compression, not forward bending, making this choice incorrect for the injury.
Choice D reason: Hyperextension involves backward bending of the spine, not typical in a fall on the feet, which causes axial compression. This mechanism does not fit the described injury, making this choice incorrect.
Correct Answer is A
Explanation
Choice A reason: Compression stockings promote venous return, preventing blood stasis in the legs, a major risk factor for deep vein thrombosis (DVT), which can lead to pulmonary embolism. By improving circulation, they reduce clot formation, making this the correct preventive action.
Choice B reason: Medications promoting clotting increase the risk of pulmonary embolism by enhancing thrombus formation. Anticoagulants, not pro-coagulants, are used to prevent clots, making this choice incorrect as it would worsen the risk.
Choice C reason: Frequent bed rest increases the risk of pulmonary embolism by causing venous stasis, promoting clot formation in deep veins. Mobility reduces stasis and clot risk, making this choice incorrect for preventing pulmonary embolism.
Choice D reason: Reducing water intake leads to dehydration, increasing blood viscosity and clot risk, which can cause pulmonary embolism. Adequate hydration maintains blood fluidity, reducing thrombosis risk, making this choice incorrect for prevention.
