NURSING EXAM 2 STUDY QUESTIONS
What is the normal arterial blood gas (ABG) range for the partial pressure of oxygen
(PO2)?
o 80-100 mmHg
o What if it’s higher than 100? What if it’s lower than 80?
▪ Higher = too much oxygenation … lower = hypoxia
➢ What is the normal arterial blood gas (ABG) range for the partial pressure of carbon
dioxide (PaCO2)?
o 35-45 mmHg
o What if it’s lower than 35? What is it’s higher than 45?
▪ Decreased = Respiratory alkalosis … increased = Respiratory Acidosis
➢ What is the normal range for the compensatory arterial blood gas (ABG) bicarbonate
(HCO3)?
o 21-28 mEq/L
o What is it’s higher than 28? What if it’s lower than 21?
▪ Higher = respiratory acidosis (compensation for metabolic alkalosis) …
Lower = respiratory alkalosis (compensating for metabolic acidosis)
➢ What is the normal range for glucose?
o 60-100 mg/dL
➢ What is the range of pre-diabetes for an impaired fasting glucose (IFG) test?
o 100-125 mg/dL
➢ What is the range of pre-diabetes for a 2 hour oral glucose tolerance (IGT) test?
o 140-199 mg/dL
➢ What is the normal range for a glycosylated hemoglobin (HbA1C) test?
, ▪ 4-6%
➢ What is the reference range for the electrolyte phosphorus?
o 3 – 4.5 mg/deciLiter
➢ What is the reference range for the electrolyte magnesium?
o 1.3 – 2.1 milli-Equivalents/Liter
➢ What is the reference range for the electrolyte chloride?
o 98 – 106 milli-Equivalents/Liter
➢ What is the reference range for the electrolyte calcium?
o 9 – 10.5 mg/deciLiter
➢ What is the reference range for the electrolyte potassium?
o 3.5 – 5 milli-Equivalents/Liter
➢ What is the reference range for the electrolyte sodium?
o 136 – 145 milli-Equivalents/Liter
➢ What is the reference range for hemoglobin?
o 14-18 gram/deciliter
➢ What is the reference range for hematocrit?
o 42-52%
➢ What is the reference range for blood osmolarity?
o 285-295 mOsm/kg
➢ What are the normal levels for serum creatinine?
o 0.6-1.2
➢ What are the normal levels for BUN?
o 10-20
➢ What are major risk factors for VTE? [Name 5]
o (1) prolonged immobility (2) central venous catheter (3) surgery
(4) obesity (5) older age (6) blood prone to clotting (7) prior history
➢ If a patient has a VTE, what are the priority nursing interventions?
[Name all in order]
o (1) oxygen therapy (2) anticoagulant or fibrinolytic therapy (3)
monitoring patient’s response
