Study Notes

Opposing the Thumb

Test opposition of the thumb by asking the patient to touch the tip of the little finger with the thumb against resistance.

Stereognosis

Test stereognosis by following these steps:
- Ask the client to close their eyes.
- Place a familiar object (e.g., key, coin, or small toy) in the patient's hand.
- Ask the patient to identify the object.

Cranial Nerves Examination

Olfactory Nerve (I)

Examine the olfactory nerve by:
- Making sure each nasal passage is open by compressing one side of the nose.
- Asking the patient to sniff through the other nasal passage.

Pupillary Reaction

Observe the constriction of the illuminated pupil.
Observe the simultaneous reaction (consensual) of the other eye.
If the reaction to light is impaired or questionable, test for near reaction in normal room light by:
- Holding a finger or pencil about 10 cm from the patient's eye.

General

Provide privacy during the examination.
