NUR2392 Multidimensional Care II Exam
2 with correct answers
Uncompensated - correct answer-pH and one other value is abnormal
Partial compensation - correct answer-pH, CO2, and HCO3 are all off
Full compensation - correct answer-pH is normal
Acidosis - correct answer-reduces the excitability of cardiovascular muscle, neurons, skeletal muscle,
and smooth muscle.
Alkalosis - correct answer-increases the sensitivity of excitable tissues allowing them to OVERRESPOND
without stimulation
ABG considerations - correct answer-- Assess cardiovascular w/ acidosis (cardiac arrest from
hyperkalemia)
- Assess neuro status
- Fall precautions
Bicarb HC03 - correct answer-kidney compensation (slow and powerful)
Respiratory PaC02 - correct answer-Respiratory compensation (fast but limited)
Metabolic acidosis causes - correct answer-DKA, Starvation, diarrhea, kidney failure, dehydration, liver
failure, pancreatitis, heavy exercise, seizure activity, fever, hypoxia, ischemia, ethanol/methanol
intoxication
Metabolic acidosis signs and symptoms - correct answer-bradycardia, hypotension, thready pulse, CNS
depression, hyporeflexia, kussmal resp (with resp compensation), warm, flushed, dry skin.
, Metabolic acidosis treatment - correct answer-hydration and medication to treat underlying problems
(DKA - give insulin).
Metabolic alkalosis causes - correct answer-antacids, blood transfusion, sodium bicarbonate, total
parenteral nutrition (TPN), prolonged vomiting, nasogastric suctioning, hypercortisolism,
hyperaldosteronism, Loop/Thiazide diuretics.
Metabolic Alkalosis s/s - correct answer-anxiety, irritability, tetany, seizures, POSITIVE CHVOSTEK,
POSITIVE TROUSSEAU, parathesis, hyperreflexia, muscle cramping/twitching, skeletal muscle weakness,
Tachycardia, norm/low BP, increased Digoxin toxicity, decreased respiratory effort (muscle weakness).
metabolic alkalosis treatment - correct answer-restore fluid/electrolyte imbalances
Respiratory acidosis cause - correct answer-Opioids, anesthetics, electrolyte imbalance, inadequate
chest expansion, muscle weakness, airway obstruction, alveolar-capillary block.
Respiratory acidosis s/s - correct answer-bradycardia, hypotension, thready pulse, CNS depression,
hyporeflexia, ineffective respirations, pale-to-cyanotic dry skin.
Respiratory acidosis treatment - correct answer-(Assess airway) Improve gas exchange, drug therapy
(bronchodilators, anti-inflammatory), oxygen therapy (lowest flow possible), ventilation.
Respiratory alkalosis cause - correct answer-Hyperventilation (fear, anxiety), mechanical ventilation,
salicylate toxicity, high altitudes, early-stage acute pulmonary issues.
respiratory alkalosis s/s - correct answer-anxiety, irritability, tetany, seizures, POSITIVE CHVOSTEK,
POSITIVE TROUSSEAU (hypocalcemia), parathesis, hyperreflexia, muscle cramping/twitching, skeletal
muscle weakness, Tachycardia, norm/low BP, increased Digoxin toxicity, hyperventilation
