The medical team believes that your patient has been suffering from a severe Viral infection, and has ordered blood to be drawn for laboratory analysis. You know that which of the following types of white blood cells is MOST associated with a Viral illness?
Neutrophils
Lymphocytes
Basophils
Eosinophils
The Correct Answer is B
A. Neutrophils are the most abundant type of WBC and are primarily involved in responding to bacterial infections. While they may increase during a viral infection, their primary function is to combat bacteria and fungi. Therefore, they are not the most specific indicator of viral illnesses.
B. Lymphocytes, which include T cells and B cells, are the most directly associated with viral infections. They play a crucial role in the adaptive immune response, recognizing and responding to viral pathogens. A significant increase in lymphocytes, particularly T cells, is commonly seen during viral infections.
C. Basophils are involved in allergic reactions and responses to parasites, releasing histamine and other mediators. They are not significantly involved in the response to viral infections and typically do not show a notable increase in these situations.
D. Eosinophils primarily respond to parasitic infections and allergic reactions. While they may be elevated in some allergic conditions and certain parasitic infections, they are not directly involved in the immune response to viral infections.

Correct Answer is A
Explanation
A. This type of shock occurs when there is widespread vasodilation leading to a relative hypovolemia, often seen in conditions like sepsis. Given that the patient has a surgical site infection, this is a plausible consideration. However, distributive shock typically involves more than just hypotension, including symptoms like warm skin and possible fever.
B. This type of shock results from significant fluid loss, leading to inadequate circulating volume. It can occur after surgery due to bleeding or fluid loss, but the context here suggests that the primary issue is infection rather than direct fluid loss.
C. Obstructive shock happens when there is a physical obstruction to blood flow, such as in cases of pulmonary embolism or tension pneumothorax. There’s no indication of obstruction in this scenario related to the infection and hypotension.
D. This shock type occurs when the heart fails to pump effectively, often due to myocardial infarction or severe heart failure. The patient’s history does not suggest heart dysfunction, so this option is less likely.
Correct Answer is A
Explanation
A. This is the first and most critical action to take. The patient's symptoms suggest a possible transfusion reaction, which can be life-threatening. Stopping the transfusion immediately prevents further exposure to potentially harmful blood components.
B. Administering oxygen may be necessary if the patient exhibits signs of respiratory distress or hypoxia. However, this action should come after ensuring that the transfusion is stopped and the patient is stabilized, as continuing the transfusion could exacerbate the reaction.
C. While providing warmth can help alleviate chills, it is not the priority action. The patient's safety is more important, and symptoms of a transfusion reaction must be addressed first.
D. Checking the temperature can provide useful information about the patient's condition, especially if a fever is present, but it is not an immediate priority. The focus should be on stopping the transfusion and managing the acute symptoms.
