What term is used to identify when a cell is temporarily deprived of blood supply
Infarction
Ischemia
Necrosis
Inflammation
The Correct Answer is B
Ischemia refers to the temporary deprivation of blood supply to a particular tissue or organ, resulting in reduced oxygen and nutrient delivery to cells. This can lead to cellular injury and, if prolonged, irreversible damage. Infarction, on the other hand, refers to the death of tissue due to prolonged ischemia. Necrosis is a type of cell death that occurs when cells are damaged or injured and cannot survive. Inflammation is the body's response to tissue injury or infection, and can be a result of ischemia or necrosis.

Explanation
Croup is a common respiratory illness in young children, characterized by inflammation of the upper airways (including the larynx and trachea) that leads to a characteristic barking cough and difficulty breathing. Croup is most commonly caused by viral infections, particularly parainfluenza virus, although other viruses such as respiratory syncytial virus (RSV) and influenza virus can also be responsible. 
Bacterial croup is rare and usually occurs in children who have an underlying condition that makes them more susceptible to bacterial infections, such as immunodeficiency or a history of recurrent respiratory infections. Fungal croup is also rare and usually occurs in children with a weakened immune system or a history of exposure to contaminated soil or other environmental sources of fungi.
Autoimmune croup is not a recognized medical condition. While some autoimmune disorders can affect the respiratory system (such as systemic lupus erythematosus), they do not typically cause croup-like symptoms.
Correct Answer is C
Explanation
Hyperventilation refers to an increased rate and depth of breathing, which results in excessive elimination of carbon dioxide (CO2) from the body. Carbon dioxide is an acidic gas that helps regulate the pH of the blood. When too much CO2 is lost through hyperventilation, it causes a decrease in the partial pressure of carbon dioxide in the blood (PaCO2), leading to a condition called hypocapnia.
Hypocapnia can cause symptoms such as lightheadedness, dizziness, and tingling in the fingers and toes.
