a)
Chemoreceptors
b)
Photoreceptors
c)
Proprioceptors
d)
Mechanoreceptors

ANS: B
Photoreceptors located in the retina of the eyes detect visible light. Proprioceptors in the skin, muscles, tendons, ligaments, and joint capsules coordinate input to enable an individual to sense the position of the body in space. Chemoreceptors are located in the taste buds and epithelium of the nasal cavity. They play a role in taste and smell. Thermoreceptors in the skin detect variations in temperature. Mechanoreceptors in the skin and hair follicles detect touch, pressure, and vibration.

5. Which nursing diagnosis has the highest priority for a patient with impaired tactile perception?
a)
Self-Care Deficit: Dressing and Grooming
b)
Impaired Adjustment
c)
Risk for Injury
d)
Activity Intolerance

ANS: C
The patient with impaired tactile perception is unable to perceive touch, pressure, heat, cold, or pain, placing him at risk for injury. Self-Care Deficit: Dressing and Grooming, Impaired Adjustment, and Activity Intolerance are also likely to be appropriate for this patient, but are not as high a priority as Risk for Injury. Risk for Injury is directly related to safety, which must always be a priority.
