Question 1

During a sleep study, a delta rhythm has been recorded for a client experiencing sleep apnea. The nurse recognizes the characteristic that is associated with this rhythm. What stage of sleep activity would be documented?

Accepted Answer

A delta rhythm is associated with slow wave sleep, which occurs during stage 3 of sleep activity. This stage is considered deep and restful and is characterized by a low level of activity in the brain. Sleep apnea can cause disruptions in this stage of sleep, leading to fragmented and poor quality sleep.

Question 2

Which of the following information should a nurse include when explaining causes of anorexia nervosa to a client? (Select all that apply.)

Accepted Answer

A possible cause of anorexia nervosa is the abnormal secretion of growth hormone and low levels of gonadotropin. There is no significant correlation between antidiuretic hormone levels, increased levels of prolactin, or altered levels of oxytocin and anorexia nervosa.

Question 3

Which of the following symptoms should a nurse associate with increased levels of thyroid-stimulating hormone (TSH) in a newly admitted client? (Select all that apply.)

Accepted Answer

Increased levels of thyroid-stimulating hormone (TSH) indicate an underactive thyroid gland (hypothyroidism). Symptoms associated with hypothyroidism include depression and fatigue. Increased libido, mania, and hyperexcitability are not typically associated with hypothyroidism.

Question 4

Which of the following symptoms should a nurse expect to assess in a client experiencing elevated levels of thyroid hormone? (Select all that apply.)

Accepted Answer

Clients with elevated levels of thyroid hormone may exhibit symptoms such as emotional lability, insomnia, and restlessness due to the hyperactivity of the thyroid gland. Depression and apathy are more commonly associated with decreased levels of thyroid hormone.
