NU 308 Exam 3 Questions And Answers Rated A+
chest pain pathophysiology ANS result of an MI caused by an imbalance between myocardial
blood supply and oxygen demand
two goals for chest pain ANS decrease oxygen demand and/or increase oxygen supply
MI diagnostics ANS best diagnostic is an ECG with elevated ST segment in 2 continuous leads,
others include:
- history of MI, ECG, blood tests (heart enzymes), stress test
- also chest x-ray, angiogram (cath), cardiac CT or MRI
MI labs ANS cardiac enzymes, troponin, creatine kinase, myoglobin will be elevated
MI symptoms ANS chest pain, shortness of breath, indigestion, nausea, anxiety, cool & pale skin,
increased HR and increased RR
organic nitrate ANS nitroglycerin
nitroglycerin MOA ANS dilates veins and decreases venous return (preload), which decreases
cardiac oxygen demand
nitroglycerin therapeutic use ANS treatment of acute angina attack, prophylaxis of chronic stable
angina, or varient angina
nitroglycerin complications ANS headache, orthostatic hypotension, reflex tachycardia, tolerance
nitroglycerin effectiveness ANS prevention of acute anginal attacks, long term management of
stable angina, control of perioperative BP, control of HF following acute MI
, priority care with MI ANS priority is assessment, assess for S&S of MI because it is an emergent
situation. stop all activity and sit/rest in bed in a semi-fowlers position. NTG & oxygen (2L/min)
3 phases of peritoneal dialysis that make up exchange ANS - inflow (fill)
- dwell (equilibrium)
- drain
dialysis inflow ANS perscribed amount of solution infused through established catheter over
about 10 minutes. after infusion, inflow clamp is closed to prevent air from entering tubing
dialysis dwell ANS diffusion & osmosis occur between patients blood & peritoneal cavity.
duration varies
dialysis drain ANS last 15-30 mins. increased drain time can be decreased or facilitated by gently
messaging abdomen or changing position
when to be concerned during peritoneal dialysis ANS cloudy peritoneal effluent = peritonitits
maintenance fluid for diabetes ANS used for when a patient is NPO. glucose, sodium, and
potassium protects patient from DKA, hypoglycemia, dehydration, and decreased electrolytes
A1C measurements ANS - normal = 3.9% to 6.5%
- impaired/prediabetes = 5.7% to 6.4% (at risk)
- DM = greater than or equal to 6.5%
DKA ANS associated with *type 1 DM*. patient can't make insulin and is *hyperglycemic*.
patient is producing *ketones* (acid) in their urine which leads to acidosis, profound hyperglycemia,
and dehydration due to the amount of sugar in the blood, causing osmotic diuresis. can progress to
*hypovolemia*
