MULTIPLE CHOICE

 

1. What is responsible for initiating the inflammatory response in addition to immunoglobulin E (IgE)?

a.	Eosinophils
b.	Lymphocytes
c.	Basophils
d.	Neutrophils

 

 

ANS:  C

Basophils initiate a massive inflammatory response with histamine that quickly brings other white blood cells (WBCs) to the site of an infection.

2. Where are histamine-releasing mast cells located?

a.	Circulating in the blood
b.	Circulating in the lymph
c.	Attached to organ tissue
d.	Embedded in the bone marrow

 

 

ANS:  C

Mast cells are located in organ tissue when they release their histamine. The organ to which they are attached is the host of the inflammatory response. If the organ is the lung, the response may be asthma; if the organ is the colon, the response may be diarrhea.

3. What is true concerning passive-acquired immunity?

a.	Antibodies are acquired from outside the host and instilled in the host.
b.	Antibodies are manufactured in response to a disease in the host.
c.	Antibodies are innately acquired because of being born a human being.
d.	Antibodies are cell mediated inside the host.

 

 

ANS:  A

Gamma globulin injections provide passive-acquired immunity. The antibodies that are injected have been produced by another host, collected, fused in the mixture, and injected into a separate host. This gives the host a passive-acquired immunity that lasts for only 2 to 3 months.

4. A nurse is alerted by the laboratory regarding a patient’s complete blood count that shows a large shift to the left. What should the nurse assess this to mean about cell level count?

a.	Neutrophils have dropped by 10%.
b.	Basophils have increased by 25%.
c.	Neutrophils have increased by 25%.
d.	Neutrophils have increased by 60%.

 

 

ANS:  D

A shift to the left indicates a sharp rise in the neutrophils to approximately 60%. The outpouring of these cells from the marrow indicates a serious and perhaps overpowering infection. Many of the cells are young and will not be able to keep up their work of immunity for as long as more mature cells would maintain immunity.
