Sigmoid

Liver

Answer and Explanation

The Correct Answer is C

A.   The sigmoid is a part of the large intestine located in the left lower quadrant, so tenderness in the right lower quadrant is unlikely to be related to the sigmoid.
B.   The liver is situated higher in the abdomen, typically more towards the right upper quadrant, and its tenderness wouldn't manifest in the right lower quadrant.
C.   Tenderness in the right lower quadrant is a classic sign of appendicitis, suggesting inflammation of the appendix.

Correct Answer is C

Explanation

A. This option inaccurately includes "electrical impulse stimulators," which is not a recognized component of the central nervous system. The central nervous system comprises the brain and spinal cord.
B. The hypothalamus and cerebral nerves are parts of the nervous system but do not represent the entirety of the central nervous system.
C. The central nervous system consists specifically of the brain and spinal cord, responsible for coordinating and processing sensory information.
D. The peripheral and autonomic components belong to the broader nervous system but are not part of the central nervous system.

A. Plantarflex the foot B. Dorsiflex the foot C. Hold both hands back to back while flexing the wrists 90 degrees for 60 seconds D. Hyperextend the wrists with the palmar surface of both hands touching, and wait for 60 seconds

Correct Answer is C

Explanation

A. Plantarflexion and dorsiflexion refer to movements of the foot and are unrelated to the Phalen test.
B. Hyperextension of the wrists with the palmar surfaces touching is not the correct maneuver for the Phalen test.
C. The Phalen test involves holding both hands back to back while flexing the wrists at a 90- degree angle for about 60 seconds, which may induce symptoms of carpal tunnel syndrome in those affected.
D. Hyperextending the wrists with the palms together doesn’t simulate the stress on the median nerve in the same way as the Phalen test.
