NURS 487 Final Exam Questions And 100%Correct Answers
What is an indicator/symptom that shock is progressing? -ANSWER During the early
stage of septic shock, the patient has warm and dry skin. Cool and clammy skin would
indicate that the shock is progressing.
neurogenic shock - ANSWER Circulatory failure caused by paralysis of the nerves that
control the size of the blood vessels, leading to widespread dilation; seen in patients
with spinal cord injuries.
What are the hallmark symptoms of Neurogenic shock? - ANSWER hypotension and
bradycardia.
What are four of the manifestations of septic shock? - ANSWER - Increased cardiac
output
- warm, flushed skin
- fever and chills
- vasodilation
What is a symptom in anaphylactic shock? - ANSWER Angioneurotic edema.
What is one of the hallmark symptoms of ARDS? - ANSWER hypoxemia.
MODS (multiple organ dysfunction syndrome) - ANSWER progressive dysfunction of two
or more organ systems due to pro-inflammatory state such as SIRS or Septic shock
What is an indication that a patient may be going from cardiogenic shock into MODS? -
,ANSWER The elevated serum creatinine level indicates that the client has renal failure
as well as heart failure.
What are some manifestations of cardiogenic shock? - ANWER Crackles, chest
pressure, and cool extremities are all consistent with cardiogenic shock.
What symptoms are indicative of ARDS? - ANWER Septicemia and laboured breathing
suggest the onset of ARDS
What is the rationale for prone positioning? - ANWER to improve the client's oxygenation
as reflected in the PaO2 and SaO2.

4. Aldosterone & ADH are increased
***OVERALL: increased extracellular fluid/ increased blood volume, increase blood
pressure, vasoconstriction, increased sodium and water retention
What happens when a hypotonic solution is administered? - ANSWER When a hypotonic
solution is administered it puts more water in the serum than is found inside cells.
Because of this, water moves into the cells to equalize the concentration of solutes
