What should a person do to prevent a pulmonary embolus from occurring?
Wear compression stockings
Take medication to promote clotting
Rest in bed frequently during the day
Reduce intake of water
The Correct Answer is A
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.

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 D
Explanation
Choice A reason: A person recovering from influenza is in the convalescent stage, not the prodromal stage, which occurs before full symptoms. Recovery indicates resolution of infection, not early nonspecific symptoms, making this choice incorrect.
Choice B reason: Cough, stuffy nose, and chest pain indicate the acute stage of influenza, with full-blown respiratory symptoms. The prodromal stage involves nonspecific symptoms before respiratory manifestations, making this choice incorrect for the prodromal phase.
Choice C reason: A person exposed to influenza with no symptoms is in the incubation period, not the prodromal stage. The prodromal stage involves early, nonspecific symptoms, not asymptomatic infection, making this choice incorrect.
Choice D reason: The prodromal stage of influenza involves early, nonspecific symptoms like fatigue, soreness, and headache before respiratory symptoms develop. These reflect the body’s initial response to viral replication, making this the correct choice for the prodromal stage.
