Á nurse is teaching a client who has septic shock about the development of disseminated intravascular coagulation (DIC). Which of the following statements should the nurse make?
"DIC is controllable with lifelong heparin usage."
"DIC is caused by abnormal coagulation involving fibrinogen."
"DIC is a genetic disorder involving a vitamin K deficiency."
"DIC is characterized by an elevated platelet count."
The Correct Answer is B
A. Lifelong heparin usage is not the standard treatment for DIC, as treatment focuses on addressing the underlying cause and managing symptoms.
B. DIC is a condition characterized by abnormal, excessive coagulation involving the use of clotting factors, particularly fibrinogen, leading to widespread clotting and bleeding.
C. DIC is not a genetic disorder or directly related to vitamin K deficiency.
D. DIC typically leads to a decreased platelet count due to consumption of platelets in widespread clotting, not an elevated count.

Correct Answer is A
Explanation
A. Antibody-mediated immunity (AMI) is primarily the result of antibodies produced by B-lymphocytes in response to antigens. This immune response is essential for protecting the body against pathogens and is particularly important in transfusion reactions.
B. While AMI is crucial in defending against various infections, it is not limited to viral infections; it also plays a significant role in protecting against bacterial infections and other types of pathogens.
C. The humoral immune response is mediated by B-lymphocytes, while T-lymphocytes are primarily involved in cell-mediated immunity, which targets infected cells and regulates immune responses.
D. Phagocytic cells, such as macrophages and neutrophils, are involved in the innate immune response, not directly in antibody-mediated immunity. Natural killer (NK) cells are part of the innate immune system and target virus-infected cells and tumors, but they do not mediate AMI.
Correct Answer is A
Explanation
A. The location of burns on the face, neck, and upper extremities is critical as it can compromise the airway, making it a priority.
B. Age is important for overall risk assessment, but airway compromise takes precedence.
C. The cause of the burn (e.g., chemical, electrical) impacts treatment but is secondary to addressing airway risks in this scenario.
D. Associated medical history provides context but does not supersede the immediate concerns related to the burn location and airway.
