After a drug enforcement agency raid on a location that housed intravenous drug users, several were brought to the hospital with rapid breathing, fever, and an altered mental state. which of the following statements is correct?

a. stained blood smears should be performed promptly to look for abnormalities in the blood cells.
b. a broad-spectrum antibiotic is needed promptly, as they are likely to be in septic shock from intravenous introduction of microbes into the blood.
c. unsanitary conditions in the house probably resulted in infestations with insects, so it's prudent to examine them for insect bites that may provide a clue.
d. many drug users are hiv-positive, so the patients should all be monitored for levels of cd4 t-cells before any other action is taken.

Option B

Explanation:

The symptoms that are discussed here matches the symptoms of septic shock. The people sharing same needle can suffer from this problem as microbes can move into the body via intravenous pathway.

Due to this there is a significant drop in the blood pressure that can lead to further problems such as increased heart rate, stroke, chills, heavy breathing, et cetera.

These people needs broad spectrum antibiotics in order to cure the symptoms of septic shock.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

the tricuspid valve is present between right atrium and right ventricle
