The nurse places a coin in the patient's hand, the patient is with eyes closed. The ability to identify an object by feeling it is defined as:
Extinction
Stereognosis
Proprioception
Two-point discrimination
The Correct Answer is B
A. Extinction refers to the phenomenon where a person fails to recognize a stimulus on one side of the body when another stimulus is presented simultaneously on the opposite side. This is often tested in cases of neurological impairment, particularly in the context of sensory neglect or loss
B. Stereognosis is the ability to identify an object by touch and proprioception without visual input. It involves recognizing the shape, size, and texture of an object solely through tactile information. Placing a coin in the patient’s hand and asking them to identify it with their eyes closed tests their ability to use tactile information to recognize objects, making stereognosis the correct term for this assessment.
C. Proprioception is the sense of the position and movement of the body and its parts. It involves awareness of body position in space, which is crucial for coordination and balance. While important, proprioception does not specifically involve identifying objects by touch alone; it is more about the awareness of body position.
D. Two-point discrimination is the ability to distinguish between two closely spaced points of contact on the skin. It tests the sensitivity of the skin to touch and is often used to assess sensory nerve function. It does not involve identifying objects by touch but rather measuring how well one can discern between two separate points of contact.

Correct Answer is A
Explanation
A. muscle strength grade of 3 indicates that the client can move the arm (or other limb) against gravity but not against any additional resistance. In this case, if the client is able to actively move the right arm against gravity, this is a correct grading. The ability to move the arm against gravity alone aligns with a grade of 3.
B. A muscle strength grade of 2 indicates that the client can move the arm (or other limb) only with gravity eliminated. This means that the client can move the limb when it is placed in a horizontal position but not against gravity. Since the client can move the arm against gravity, this grade is not applicable.
C. A muscle strength grade of 1 indicates that there is muscle contraction but no movement of the limb. This means there is some visible muscle activity but insufficient to cause any joint movement. Since the client is able to move the arm actively against gravity, this grade does not fit the observed finding.
D. A muscle strength grade of 5 indicates normal strength, where the client can move the limb against gravity and against full resistance. If the client can move the right arm against gravity but not necessarily against full resistance, this is not indicative of a grade of 5. The grade of 5 would be reserved for when the muscle can move against full resistance without difficulty.
Correct Answer is C
Explanation
A. Kyphosis is a condition characterized by an excessive outward curvature of the thoracic spine, leading to a hunchbacked appearance. It often results from degenerative diseases, osteoporosis, or other spinal conditions.
B. Lordosis refers to an excessive inward curvature of the lumbar spine, often referred to as "swayback." This condition can be congenital or due to other factors like obesity or pregnancy.
C. Osteoporosis is a bone condition characterized by decreased bone density and strength, leading to an increased risk of fractures. It is particularly common in postmenopausal women due to decreased estrogen levels, which help maintain bone density.
D. Scoliosis is a condition characterized by an abnormal lateral curvature of the spine. It can be congenital, idiopathic, or secondary to other conditions.
