Nur 205 Exam 3 (Latest Update 2026 /
2027) Fundamentals of Nursing Questions
AND Answers {Grade A} 100% Correct –
Hondros
How do the kidneys compensate? - correct answer Excreting excess acid and bicarb
(HCO3)
OR
Retaining hydrogen and bicarb (HCO3)
How do the lungs compensate? - correct answer Hyperventilating = decreased CO2 =
alkalosis
Hypoventilating = increased CO2 = Acidosis
Respiratory Acidosis patho - correct answer *Lung problem, kidneys compensate*
-The lungs are retaining too much CO2
-The kidneys excrete hydrogen and retain bicarb
,Respiratory Acidosis causes - correct answer Retaining CO2 "depress" breathing
*D*rugs (opioids and sedatives
*E*dema (fluid in lungs)
*P*neumonia (excess mucus in the lungs)
*R*espiratory center of brain is damaged
*E*mboli (pulmonary emboli)
*S*pasms of the bronchial (asthma)
*S*ac elasticity damage (COPD and emphysema)
*all cause impaired gas exchange*
Respiratory Acidosis interventions - correct answer Administer O2
Semi-fowlers position
Turn, cough, deep breath
Increase fluids
Monitor potassium levels
,Respiratory Acidosis Signs and Symptoms - correct answer Hypoxia
Decreased blood pressure
Decreased respiration rate
Increased heart rate
Confusion
Headache
Sleepy/coma
Respiratory Alkalosis Patho - correct answer -The lungs are losing too much CO2
-The kidney excrete bicarb (HCO3) & retain hydrogen
Respiratory Alkalosis Causes - correct answer *Losing CO2*
Tachypnea
Increased temperature
Aspirin toxicity
Hyperventilation
, Respiratory Alkalosis Signs and symptoms - correct answer Increased respiratory
rate
Increased heart rate
Confused and tired
Positive Chvostek sign--twitching of facial muscles when tapping the facial nerve
Respiratory Alkalosis Interventions - correct answer Rebreathing into a paper bag
Give anti anxiety medications to decrease breathing
Monitor potassium and calcium levels
Metabolic Acidosis Patho - correct answer *Kidney problem, lungs compensate*
-Too much hydrogen, too little bicarb (HCO3)
-The lungs will blow off CO2
Metabolic Acidosis causes - correct answer DKA
Acute/chronic kidney injury
