NURSING 172 TEST PAPER UPDATED QUESTIONS AND
ANSWERS GRADED A+
✔✔Primary continuous administration sets - ✔✔these are the main administration sets
used to deliver solutions and medications
✔✔PRIMARY TUBING- Continuous administration sets - ✔✔these are changed every
96 hours or immediately upon suspected contamination
✔✔PIGGYBACK- Secondary administration sets - ✔✔used for medication
administration and is attached to the primary administration set. Tubing changed every
24 hours
✔✔When you administer a piggy back solution? - ✔✔the primary solution is hung on the
extension hook
✔✔How often is the intermittent administration set changed - ✔✔every 24 hours
✔✔stopcock - ✔✔This device controls the flow of a solution with manual manipulation of
the valve
✔✔The use of stopcocks increases this risk? - ✔✔infection
✔✔Which connectors allow the tip of a syringe to be attached? - ✔✔Intermittent infusion
or needless connector
✔✔True or False: An Ohio LPN can change needless connectors on a CVC? - ✔✔False
✔✔Stabilization device - ✔✔This prevents pistoning of the catheter
✔✔Normal ABG values - ✔✔pH = 7.35-7.45
PaCO2 = 35-45
HCO3 = 22-26
✔✔IF the pH is acidosis and the CO2 level is acidosis then the ABG is? - ✔✔respiratory
acidosis
✔✔If the pH is alkalosis and CO2 level is alkalosis then the ABG is - ✔✔respiratory
alkalosis
✔✔If the pH is acidosis and HCO3 level is acidosis then the ABG is - ✔✔metabolic
acidosis
, ✔✔If the pH is alkalosis and HCO3 level is alkalosis then the ABG is - ✔✔metabolic
alkalosis
✔✔uncompensated ABG - ✔✔pH is abnormal and EITHER CO2 or HCO3 is abnormal
✔✔partially compensated ABG - ✔✔all three pH, CO2, and HCO3 are abnormal
✔✔fully compensated ABG - ✔✔pH is normal and CO2 and HCO3 is abnormal
✔✔Respiratory acidosis - ✔✔pH < 7.35
PaCO2 > 45
Kidneys can compensate by retaining HCO3 to minimize acidosis
✔✔Clinical manifestations of respiratory acidosis - ✔✔confusion
drowsiness
weakness
shortness of breath
high potassium
✔✔Causes of respiratory acidosis - ✔✔shallow respirations
respiratory depression
opioid overdose
pneumonia
COPD
✔✔Treatment for respiratory acidosis - ✔✔apply oxygen
correct causative factor
✔✔Respiratory alkalosis - ✔✔pH > 7.45
PaCO2 < 35
Kidneys can compensate by excreting HCO3 to minimize alkalosis
✔✔clinical manifestations of respiratory alkalosis - ✔✔mental status changes
pallor around the mouth
tingling of the fingers
spasms of hand muscles
low potassium
✔✔Causes of respiratory alkalosis - ✔✔increased respiratory rate
hyperventilation
anxiety
lung disorders that cause SOB
hypoxia
✔✔Treatment of respiratory alkalosis - ✔✔sedation
