A 22-year-old patient with a history of iv drug abuse arrives at the clinic complaining of fever, night sweats, and weight loss. the physician suspects acquired immune deficiency syndrome an infectious disease caused by the human immunodeficiency virus.

Acquired immune deficiency syndrome or AIDS is a disease caused by the human immunodeficiency virus or HIV wherein it attacks the body's immune system mainly the lymphocytes, specifically the helper T-cells which mainly promotes the differentiation of B cells into plasma cells. With a low helper T-cell count, there will be increased risk for other infectious diseases such as pneumonia and tuberculosis.

A patient is diagnosed with heart failure. during assessment, the patient's feet show an abnormal accumulation of fluid, a condition known as edema. 

Edema is the accumulation of fluid to the interstitial space. In a patient with heart failure, there is edema of the feet as a result of increased filtration of the plasma due to the increased capillary hydrostatic pressure brought about by the pooling of blood to the systemic circulation as a result of right-sided heart failure. In left sided heart failure, pooling of blood is in the pulmonary circulation causing pulmonary edema.

Brittany E., a college freshman, tells her roommate that she has a sore throat, tiredness, fever, and swollen neck glands. Brittany's roommate encourages her to go to the college infirmary, where the nurse suspects infectious mononucleosis, an acute infection caused by the Epstein-Barr virus.

Infectious mononucleosis is a diseases characterized by sore throat, fatigue, fever, and prominent cervical lymphadenopathy caused by Epstein-Barr virus or EBV. Infectious mononucleosis is common among people in the teenage group as this is mostly transmitted by kissing (hence called as the kissing disease). EBV infection also predisposes the patient into developing nasopharyngeal carcinoma, especially if untreated.

A 73-year-old patient is admitted from a longterm care facility with fever and chills. blood cultures identify the presence of Escherichia coli. the physician diagnoses septicemia, also known as a blood infection.

Septicemia is the systemic inflammatory response with consequential tissue damage in the background of severe systemic infection, especially in the blood. The presence of E. coli in blood cultures confirms the presence of bacteria in the blood causing sepsis. Sepsis can proceed to septic shock, with signs such as low blood pressure and cold, clammy extremities, which can lead to death if untreated.

Kate S. is brought to the emergency department by her husband because she has had a fever for the past 3 days. blood specimens are drawn and her white blood cell count is elevated. the physician asks the laboratory staff to perform a(n) differential count to determine the distribution of white blood cells.

A differential count is a component of complete blood count wherein it aims to determine the distribution of different kinds of white blood cells. The different kinds of white blood cells are neutrophils, lymphocytes, eosinophils, basophils, and monocytes. The percentages of differential count will determine whether the infection is acute/bacterial (neutrophil predominant), chronic/viral (lymphocyte predominant), allergic (presence of eosinophils and/or basophils), etc.
