A nurse working at nights is constantly complaining of being tired and sick. It seems like she catches every illness that is on the unit. One possible reason for this may relate to:

A) She does not contain the "hardiness" gene in her system.
B) Alterations in sleep–wake cycle have decreased her immune function.
C) She is stressing too much about being tired and sleepy.
D) Maybe she should get tested for sleep apnea.


Ans: B
Feedback:
Sleep disorders and alterations in the sleep–wake cycle have been shown to alter immune function, the normal circadian pattern of hormone secretion, and physical and psychological functioning. The concept of hardiness describes a personality characteristic that includes a sense of having control over the environment, a sense of having a purpose in life, and an ability to conceptualize stressors as a challenge rather than a threat. Lower levels of hardiness have been linked with greater reaction to stress. Stress is probably one of the primary factors interfering with sleep. At this time, we do not have enough data to speak to the need for a sleep apnea exam.
