What is a normal response of the body to a failure in one component of the acid base
regulatory mechanism? - answers compensation
A patient has a pH of 7.49. How would you describe this? - answers alkalemia
An ABG result shows the pH to be 7.56 and the HCO3 23 nmEq/L. Which of the
following is the most likely disorder? - answers Respiratory alkalosis
How is acute respiratory acidosis corrected? - answers By increasing alveolar
ventilation
An ABG shows pH of 7.35, PaCO2 of 30mmHg and HCO3 of 18 mEq/L Which of the
following is the patients most likely primary disorder? - answers Metabolic acidosis
Pulse oximeter readings are generally unreliable at saturations below what level? -
answers 90% and below
Precautions and/or possible complications of arterial puncture include which of the
following? - answers Arteriospasm, Embolization, Infection Hemorrhage
You are the respiratory therapist caring for a patient who was admitted to the ED for an
asthma exacerbation. You draw an ABG and receive the following results: pH = 7.48,
PCO2 = 28 mmHg, PaO2 = 62 HCO3 = 24.3 mEq/L
What would your initial treatment be? - answers Initiate oxygen therapy by HHFNC at
35 LPM and FiO2 of 80%
, Based on the following ABG results, what is the most likely acid-base diagnosis? PH
7.08, PCO2 39mmHg, HCO3 11.8 mEq/L - answers Acute (uncompensated) metabolic
acidosis
A PaO2 below what value would be considered moderate hypoxemia? - answers
55mmHg
Your patient has a blood urea nitrogen (BUN) level of 48mg/dl. This is likely due to a
problem with what organ? - answers Kidneys
If patient pain or anxiety occurs during arterial puncture, which of the following will
probably occur? - answers hyperventilation
Causes of respiratory acidosis in patients with normal lungs include which of the
following? - answers Neuromuscular disorders, spinal cord trauma, anesthesia
You are called to the ED to evaluate a patient who is tachypneic. You enter the room
and immediately see the pt is breathing in a Kussmaul's pattern. You draw an ABG and
receive the following results: pH = 7.27, PCO2 = 18mmHg, PaO2 = 86 HCO3 = 12
mEq/L - answers Diabetic ketoacidosis
Which of the following sites are used for arterial blood sampling by percutaneous needle
puncture? - answers Femoral, radial, brachial
A solution that resists large changes in PH upon addition of an acid or a base best
describes which of the following? - answers Buffer solution
The primary goal of acid - base homeostasis is to maintain which of the following? -
answers Normal pH
Which of the following would indicate your patient has cystic fibrosis? - answers A
sweat chloride level of greater than 60 mmol/L
Which of the following is NOT an indication for ABG analysis? - answers History of
smoking
Which of the following describes the correct procedure for an Allen test? - answers
Compress both the radial and ulnar arteries, and then release the ulnar artery
Which of the following clinical findings would you expect in a fully compensated
respiratory acidosis? - answers elevated HCO3- and pH between 7.35-7.39
Which of the following is NOT part of the proper procedure for ABG sampling from a
radial artery? - answers Puncture the skin with the bevel down
