- Nursing concerns for neurogenic shock
- Use of isoproterenol (Isuprel) in cardiogenic shok
- what is the universal blood type
- Two symptoms common to all types of shock?
- symptoms of shock
- a O-negative
- b Limited to shock associated with slow HR and myocardial depression. Not a first line drug, used when pt not responsive to other meds.
- c mental confusion, depression, apathy, oliguria, heart failure (low CO), tachycardia (report HR >100/min), thready pulse, thirst, restlessness, anxiety, lethargy, cool extremities, pale skin, frequently hypotension (report BP <90), fainting, syncope rapid, shallow breathing (body trying to get more O2), metabolic acidosis, coma.
- d mental confusion and oliguria
- e VS, elastic compression stockings, HOB elevated 30 degrees.
5 Multiple Choice Questions
- I&O, VS, ECG, CNS checks, electrolytes, clotting times, respiratory status, hemodynamic monitoring, and family needs.
- MI, arrhythmias, valvular disease, cardiac surgery, cardiomyopathy.
- Drug of choice for cardiogenic shock because does not cause vasoconstriction but increases strength of contractions, improves stroke volume and CO. Minimal increase in HR. has a half-life of 2 minutes, given as an IV infusion drip, dosed in mcg/kg/min. only give in the ICU
- to reverse low BP effect of nitroglycerin and morphine (MS) by elevating BP to perfuse vital organs. Causes peripheral vasoconstriction (alpha 1) and increases the force of contraction (beta 1 w/ IV fusion only). Potential to cause tachycardia.
- previous exposure to allergen with resulting antibody formation - exposure again to substance - develops a systemic antigen-antibody reaction - mast cells are provoked to release potent vasoactive substances, ie histamine or bradykinin - widespread vasoD and cap perm - Decreased venous return to heart - Decreased stroke volume - Decreased CO - Decreased BP - Decreased tissue perfusion - Respiratory arrest - Cardiac arrest - Death
5 True/False Questions
Nursing considerations for hypovolemic shock → I&O, VS (especially temp), labs.
hypovolemic shock → absolute volume loss or relative volume loss as with ascites (3rd spacing) - 10-31% mortality rate.
Medical management of neurogenic shock → Stabilization of spinal cord injury, positioning spinal anesthetic patient properly, giving glucose for hypoglycemia.
distributive shock → vasodilation d/t mediators of inflammatory process in response to overwhelming INFECTION - 40-70% mortality rate depending on organism.
Use of norephinephrine (Levophed) in cardiogenic shock → Vasoconstriction alpha 1 stimulator
