MARYVILLE PATHO NURS 611 EXAM 2
1. Parasympathetic nervous system: Body system responsible for conserving energy and body resources 2. Sympathetic nervous system (SNS): Body system that responds to stress by preparing the body to defend itself 3. how is blood flow redistributed by the sympathetic nervous system (SNS)- : blood flow to the muscles is increased while blood flow to GI and integumentary is decreased 4. how are primary brain injuries classified: Focal or diffuse (aka multifocal) 5. focal brain injuries: specific, grossly observable brain lesions that occur in a precise location Epidural and subdural hemorrhages
611-PATHO EXAM
1. What are clinical manifestations of hypothyroidism? a. Intolerance to heat, tachycardia, and weight loss b. Oligomenorrhea, fatigue, and warm skin c. Restlessness, increased appetite, and metrorrhagia d. Constipation, decreased heat rate, and lethargy The lower levels of thyroid hormone result in decreased energy metabolism, resulting in constipation, bradycardia, and lethargy, thus eliminating the remaining options. 2. Thyroid-stimulating hormone (TSH) is released to stimulate thyroid hormone (TH) and is inhibited when plasma levels of TH are adequate. This is an example of: a. Positive feedback b. Neural regulation c. Negative feedback d. Physiologic regulation Negative feedback. Feedback systems provide precise monitoring and control of the cellular environment. Negative feedback occurs because the changing chemical, neural, or endocrine response to a stimulus negates the initiating change that triggered the release of the hormone. Thyrotropin-releasing hormone (TRH) from the hypothalamus stimulates TSH secretion from the anterior pituitary. Secretion of TSH stimulates the synthesis and secretion of THs. Increasing levels of T4 and triiodothyronine (T3) then generate negative feedback on the pituitary and hypothalamus to inhibit TRH and TSH synthesis.
