NUR 265 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 (PaCO2)?
o
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) (HCO3)?
o
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

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
➢ If a patient is suspected of a VTE, when should you sit them in high-Fowler’s position?
o Immediately after putting them on oxygen
➢ If a patient with a VTE is receiving fibrinolytics, what antidotes should be ready in case of overdose? [Name all]
o (1) clotting factors (2) fresh frozen plasma (3) aminocaproic acid (Amicar)
➢ What are 4 priority problems for a patient with a PE? [Name all in order]
o (1) hypoxemia (2)hypotension (3) potential for bleeding related to anticoagulant/fibrinolytic therapy (4) anxiety
➢ What are the classic symptoms for a PE? [Name all]
o (1) sudden onset of dyspnea (2) sharp, stabbing chest pain (3) restlessness (4) feeling of impending doom (5) cough (6) hemoptysis
o What other symptoms may they experience? [Name 3]
▪ (1) tachypnea (2) crackles (3) pleural friction rub (4) tachycardia (5) sweating (6) low-grade fever (7) decreased O2 Saturation (8) S3 or S4 heart sounds/gallop
(9) petechiae all over chest
➢ What conditions could cause a patient to be at risk for ventilatory failure? [Name 5]
o (1) COPD (2) Pulmonary Embolism or PE (3) ARDS (4) pulmonary edema (5) stroke (6) increased intracranial pressure (7) opioids (8) spinal cord injury (9) massive obesity
(10) sleep apnea
➢ What is the hallmark of acute respiratory distress syndrome (ARDS)?
o Hypoxemia that persists even with 100% oxygen
➢ If your patient is at risk for a PE, what symptoms would let you know to notify the rapid response team? [Name all]
o (1) jugular vein distention (2) syncope (3) cyanosis (4) hypotension
➢ What method is most commonly used to diagnose a PE?
o CT scan
➢ Despite the different causes for acute lung injury, what triggers ARDS?
o Systemic inflammatory response
➢ What is the nursing priority in the prevention of ARDS?
o Early recognition in high risk patients
➢ What kind of patients are considered at high risk for ARDS?
o (1) patients with tube feeding and impaired swallow/gag reflex because of aspirating very acidic gastric contents (2) pancreatitis (3) transfusion reactions (4) trauma
o What physical assessments indicate early symptoms of ARDS?
▪ (1)assess breathing – (a) for increased rate (b) noisy respirations (c) retractions (d) increased effort; (2) cyanosis (3) mental status (4) pallor (5) hypotension
(6) tachycardia (5) dysrhythmias
▪ Why don’t you assess for abnormal lung sounds?
• Because it occurs in the interstitial spaces first and not the airways
➢ What is FiO2 ?
