Which statement about nonspecific (innate immunity) is true?.

hoice A rationale:

Peyer’s patches are lymphoid nodules located in the small intestine, not at the back of the throat.

Choice B rationale:

Lymph is a fluid that contains white blood cells and circulates throughout the lymphatic system, not a tissue located at the back of the throat.

Choice C rationale:

Tonsils are lymphoid tissues located at the back of the throat. They help protect the body from respiratory infections.

Choice D rationale:

The appendix is not located at the back of the throat. It is a narrow pouch that projects off the cecum in the digestive system.

Choice A rationale:

Abdominal thrusts, also known as the Heimlich maneuver, are a first-aid technique used to treat conscious choking victims in which the rescuer delivers thrusts to a patient’s upper abdominal region. This motion pushes air from the lungs up through the throat to dislodge foreign objects and treat upper airway obstructions.

Choice B rationale:

Chest thrusts can also be used if needed. However, they are not the primary method for dislodging a foreign object in someone that is choking.

Choice C rationale:

Chest pumps are not a recognized method for dislodging a foreign object in someone that is choking.

Choice D rationale:

Bowel thrusts are not a recognized method for dislodging a foreign object in someone that is choking.

So, the correct answer is Choice A.
