pulmonary disease and was rushed to the emergency department with
increasing shortness of breath, pyrexia, and a productive cough with yellow-
green sputum. He has difficulty in communicating because of his inability to
complete a sentence. One of his sons, Jacob, says he has been unwell for three
days. Upon examination, crackles and wheezes can be heard in the lower lobes;
he has a tachycardia and a bounding pulse. Measurement of arterial blood gas
shows pH 7.3, PaCO2 68 mm Hg, HCO3 28 mmol/L, and PaO2 60 mm Hg. How
would you interpret this?
A. Respiratory Acidosis, Uncompensated
B. Respiratory Acidosis, Partially Compensated
C. Metabolic Alkalosis, Uncompensated
D. Metabolic Acidosis, Partially Compensated
2. Carl, an elementary student, was rushed to the hospital due to vomiting and
a decreased level of consciousness. The patient displays slow and deep
(Kussmaul breathing), and he is lethargic and irritable in response to
stimulation. He appears to be dehydrated—his eyes are sunken and mucous
membranes are dry—and he has a two week history of polydipsia, polyuria, and
weight loss. Measurement of arterial blood gas shows pH 7.0, PaO2 90 mm Hg,
PaCO2 23 mm Hg, and HCO3 12 mmol/L; other results are Na+ 126 mmol/L, K+
5 mmol/L, and Cl- 95 mmol/L. What is your assessment?
A. Respiratory Acidosis, Uncompensated
B. Respiratory Acidosis, Partially Compensated
C. Metabolic Alkalosis, Uncompensated
D. Metabolic Acidosis, Partially, Compensated

Suddenly, she started complaining that she is still in pain and now experiencing
muscle cramps, tingling, and paraesthesia. Measurement of arterial blood gas
reveals pH 7.6, PaO2 120 mm Hg, PaCO2 31 mm Hg, and HCO3 25 mmol/L. What
does this mean?
A. Respiratory Alkalosis, Uncompensated
B. Respiratory Acidosis, Partially Compensated
C. Metabolic Alkalosis, Uncompensated
D. Metabolic Alkalosis, Partially Compensated

dry mucus membranes and her capillary refill takes >4 seconds. She is
diagnosed as havinggastroenteritis and dehydration. Measurement of arterial
blood gas shows pH 7.5, PaO2 85 mm Hg, PaCO2 40 mm Hg, and HCO3 34
mmol/L. What acid-base disorder is shown?
A. Respiratory Alkalosis, Uncompensated
B. Respiratory Acidosis, Partially Compensated
C. Metabolic Alkalosis, Uncompensated
D. Metabolic Alkalosis, Partially Compensated
5. Mrs. Johansson, who had undergone surgery in the post-anesthesia care unit
(PACU), is difficult to arouse two hours following surgery. Nurse Florence in the
PACU has been administering Morphine Sulfate intravenously to the client for
complaints of post-surgical pain. The client’s respiratory rate is 7 per minute
and demonstrates shallow breathing. The patient does not respond to any
stimuli! The nurse assesses the ABCs (remember Airway, Breathing,
Circulation!) and obtains ABGs STAT! Measurement of arterial blood gas shows
pH 7.10, PaCO2 70 mm Hg and HCO3 24 mEq/L. What does this mean?
A. Respiratory Alkalosis, Partially Compensated
B. Respiratory Acidosis, Uncompensated
C. Metabolic Alkalosis, Partially Compensated
D. Metabolic Acidosis, Uncompensated
6. Baby Angela was rushed to the Emergency Room following her mother’s
complaint that the infant has been irritable, difficult to breastfeed and has
haddiarrhea for the past 3 days. The infant’s respiratory rate is elevated and
the fontanels are sunken. The Emergency Room physician orders ABGs after
assessing the ABCs. The results from the ABG results show pH 7.39, PaCO2 27
mmHg and HCO3 19 mEq/L. What does this mean?
A. Respiratory Alkalosis, Fully Compensated
B. Metabolic Acidosis, Uncompensated
C. Metabolic Acidosis, Fully Compensated
D. Respiratory Acidosis, Uncompensated
7. Mr. Wales, who underwent post-abdominal surgery, has a nasogastric tube.
