The nurse is performing an assessment on a patient and asks the patient to close their eyes and places a familiar object in the patient's hand.
The nurse asks the patient to identify the object.
This is known as:
Graphesthesia.
Rhomberg.
Superficial reflexes.
Stereognosis.
The Correct Answer is D
Choice A rationale
Graphesthesia is a sensory ability that allows an individual to recognize numbers or letters traced on their skin with their eyes closed. This assesses cortical sensory function, specifically the ability to interpret tactile stimuli, which is distinct from identifying a three-dimensional object by touch alone.
Choice B rationale
The Romberg test assesses proprioception and cerebellar function by asking the patient to stand with feet together and eyes closed. A positive Romberg sign indicates a loss of balance, suggesting a deficit in proprioception or vestibular function, and is not related to the identification of objects by touch.
Choice C rationale
Superficial reflexes, such as the plantar reflex or abdominal reflex, are elicited by light tactile stimulation of the skin and involve spinal cord reflex arcs. These reflexes assess the integrity of specific neurological pathways and are distinct from the cognitive process of identifying an object through tactile recognition.
Choice D rationale
Stereognosis is the ability to recognize familiar objects by touch and manipulation, without visual input. This cortical sensory function integrates tactile, proprioceptive, and kinesthetic sensations to form a mental image of the object's shape, size, and texture, allowing for its identification.

Correct Answer is C
Explanation
Choice A rationale
While palpation is a critical skill, this statement does not directly complete the given sentence which defines palpation as a technique. The existing sentence establishes the "what" of palpation, and the completion should elaborate on "how" it's performed or its direct characteristics.
Choice B rationale
Palpation certainly helps identify abnormalities, but this statement describes a benefit or outcome of the technique, not the core method itself as described in the initial sentence. The sentence sets up the physical action, not its diagnostic utility.
Choice C rationale
This choice logically completes the sentence by explaining the *methodology* of palpation, directly following the description of the senses involved and what is being assessed. It specifies that the technique involves "careful and systematic touching of the body," which directly relates to the physical act of assessment.
Choice D rationale
Proper palpation technique ensures accurate examinations, but this statement focuses on the *quality* of the technique rather than describing the technique itself. The initial sentence defines the technique; the completion should expand on its execution, not its outcome. .
Correct Answer is ["0.004"]
Explanation
Step 1 is: Convert mcg to mg. There are 1000 mcg in 1 mg.
Step 2 is: 4 mcg ÷ (1000 mcg/1 mg) = 0.004 mg. Answer: 0.004 mg.
