what are S/S of Metabolic Alkalosis? -Correct Answer ✔-- pH above 7.4 -- low H+
- bradycardia
- tetany
- postural hypotension
in Metabolic Alkalosis what is compensating mechanism? -Correct Answer ✔-
LUNGS -- HYPOventilation
what are buffers? -Correct Answer ✔-chemicals that help to regulate pH (bicarb)
what is the first line of defense? -Correct Answer ✔-buffers
what is the second line of defense? -Correct Answer ✔-respiratory system
what is the third line of defense? -Correct Answer ✔-renal system
what is compensate for metabolic acidosis? -Correct Answer ✔-LUNGS --
HYPERventilate
,in metabolic acidosis what system is the problem? -Correct Answer ✔-kidneys!!!
what is the most common cause of metabolic acidosis? -Correct Answer ✔-
diarrhea!! (decreased base)
in metabolic acidosis, what makes excess acid? -Correct Answer ✔-- starvation
diets, body will break down fats but not completely (causes ketoacidosis)
- lactic acidosis
- circulatory shock
what are S/S of Metabolic Acidosis? -Correct Answer ✔-- pH below 7.4: more H+
- headache: due to cerebral vasodilation
- abdominal pain: from excessive defecation
- CNS depression (confusion, lethargy, coma): due to altered pH
what is the problem in Respiratory Acidosis? -Correct Answer ✔-LUNGS --
hypoventilation IS the cause
what are the causes of Respiratory Acidosis? -Correct Answer ✔-- impaired gas
exchange (COPD, bacterial pneumonia, asthma)
- brain injury or stroke -- MAIN CAUSE
- Guillan-Barre Syndome: inability to use voluntary muscles
- opioids
what was the clinical manifestations of Respiratory Acidosis? -Correct Answer ✔--
pH below 7.4
, - headache: vasodilation
- tachycardia: from heart cells being affected by pH change
- dyrrhythmias (hyperkalemeia)
- neurologic abnormalities
what type of neurologic abnormalities will patients with respiratory acidosis
experience? -Correct Answer ✔-- blurred vision
- tremors
- vertigo
- disorientation/lethargy
why will patients with Respiratory Acidosis experience dysrhthmias? -Correct
Answer ✔-due to too much potassium (cells will take in H+ and kicks out
potassium in the blood)
what system is the problem in Respiratory Alkalsosis? -Correct Answer ✔-LUNGS -
- we are breathing too fast, possibly bc we are hypoxic (air hungry)
what is Respiratory Alkalsosis due to? -Correct Answer ✔-- tachycardia
- fever
- pain
- alcohol withdrawal
- prolonged sobbing
what are the S/S of Respiratory Alkalsosis? -Correct Answer ✔-- numbness and
tingling: from HYPOcalcemia
- carpal & pedal spasms
