____       1.   The nurse checks a patient’s pupils using a penlight. Which receptors is the nurse stimulating?

1)

Chemoreceptors

2)

Photoreceptors

3)

Proprioceptors

4)

Mechanoreceptors

 

ANS:       2

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.

____       2.   Which structure within the brain is responsible for consciousness and alertness?

1)

Reticular activating system

2)

Cerebellum

3)

Thalamus

4)

Hypothalamus

 

 

ANS:       1

The reticular activating system, located in the brainstem, controls consciousness and alertness. The cerebellum maintains muscle tone, coordinates muscle movement, and controls balance. The thalamus is a relay system for sensory stimuli. The hypothalamus controls body temperature.

____       3.   The nurse has been teaching a parent about stimuli to develop her infant’s auditory nervous system. Which behavior by a parent toward the child provides evidence that learning occurred?

1)

Cuddling

2)

Speaking

3)

Feeding

4)

Soothing

 

 

ANS:       2

Exposure to voices, music, and ambient sound helps develop the infant’s auditory nervous system. Cuddling, feeding, and soothing provide comfort and pleasure and teach the infant about his external environment.

____       4.   A patient complains to the nurse that since taking a medication he has suffered from excessively dry mouth. What term should the nurse use to document this complaint?

1)

Exophthalmos

2)

Anosmia

3)

Insomnia

4)

Xerostomia

 

 

ANS:       4

The nurse should document excessively dry mouth as xerostomia. Exophthalmos is abnormal bulging of the eyeballs that commonly occurs with thyrotoxicosis. Anosmia is losing the sense of smell. Insomnia is inability to sleep.

____       5.   Which nursing diagnosis has the highest priority for a patient with impaired tactile perception?

1)

Self-Care Deficit: Dressing and Grooming

2)

Impaired Adjustment

3)

Risk for Injury

4)

Activity Intolerance

 

 

ANS:       3

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, 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.
