NUR 276 FINAL EXAM STUDY GUIDE
SOLUTIONS

Be able to explain the relationship between the concepts of stress and coping, cellular regulation, and

oxygenation/perfusion - Ans:✔✔-*Respiratory*: Increased ventilatory rate and depth of respirations,

dilation of bronchioles to facilitate increased oxygenation


*Cardiac*: Increased heart rate and cardiac output to promote transport of oxygen and nutrients

throughout the body


*Integumentary*: Increased sweat production (diaphoresis) to offset increased body temperature

secondary to increased metabolism; skin pallor secondary to vasoconstrictive effects of norepinephrine


*GI*: inhibition of the parasympathetic nervous system leads to decreased motility of gastric and

intestinal contents (peristalsis) through the gastrointestinal tract, which may cause constipation and

exccess flatus (intestinal gas); dry mouth due to decreased salivation secondary to inhibition of the

parasympathetic nervous system.


*Urinary*: Increased sodium and water retention due mineralocorticoid release, which leads to

decreased urine output and increased blood volume


*Opthalmic*: Pupillary dilation to allow entrance of more light and enhanced visual perception

Neurological: Enhances awareness and alertness in response to severe threats


*Musculoskeletal*: Increased muscular tension in preparation for defense (flight) or rapid mobility

(flight)


*Endocrine*: Increased release of glucocorticoids and increased gluconeogenesis, which leads to an

increased serum glucose (blood sugar)


What lab values are affected by stress and know why (Page 1903) - Ans:✔✔-Stress Response causes




research suggests that peer rejection stimulates an increase in systolic blood pressure and in the

production of saliva a-amylase (sAA), which is an enzyme that is reflective of sympathetic nervous

system activation. Additionally, stressors related to performance-based challenges were associated with

increased cortisol production and increased diastolic blood pressure




1. Release of *catecholamines* and *epinephrine* and *norepinephrine*. This causes an increase in

blood pressure and heart rate.


2. Release of *glucocorticoids* and increased gluconeogenesis


3. Increased serum glucose-increased risk for hyperglycemia and poor glucose control in clients with

diabetes

prolonged exposure to stress may lead to significant enlargement of the adrenal glands and pronounced

shrinkage (atrophy) of the lymphatic structures, including the lymph nodes, thymus, and spleen.

Additionally, within the gastrointestinal tract, ulcers may develop.




the sympathetic nervous system triggers the body's "fight-or-flight" response, which is necessary for

survival. Activation of the sympathetic nervous system causes release of hormones such as epinephrine,

which increases the heart rate and blood pressure to assist in the delivery of oxygen to tissues and

organs. Epinephrine also causes bronchial dilation, which allows for increased oxygen uptake. This

increase in oxygen uptake and delivery is intended to meet the increased metabolic demands associated

with facing a stressor (fight) or escaping the stressor (flight).




Local Adaptation Syndrome (LAS):


1. Alarm reaction: Body prepares for cascade of physiological reactions


2. Resistance: Body attempts to move toward restoration of homeostasis


3. Exhaustion: Energy and resources become depleted, body may rebound or disease/death may occur

epinephrine- increased heart rate


Know how the nurse should interact/intervene with a client experiencing anxiety or stress (Page 1906) -

Ans:✔✔-Initial nursing actions that inspire client confidence and that may help calm anxious clients:


1. Make eye contact, focusing on the person


2. Take a nonthreatening stance


3. Validate the client's feelings: "I know you are very uncomfortable; we will do everything we can to

help you feel better."


4. Determine and address the client's immediate concerns: "What can I do right away to help you?"


5. Remember to address the client by name. Some clients find terms of endearment such as "honey" or

"sweetie" impersonal or demeaning. Using the client's first name may be seen as patronizing if the client

is expected to use the nurse's last name. On the other hang, some clients respond positively to the

informality of first name use. Ask clients how they would prefer to be addressed and never use the first

name of anyone over 18 without permission.


6. Recognize and acknowledge manifestations of stress


7. Identify health coping mechanisms, including ensuring adequate time aware from the workplace and

incorporation of recreational activities into personal life
