⩥ A Respiratory Alkalosis, Uncompensated
The primary disorder is acute respiratory alkalosis (low CO2) due to the
pain and anxiety causing her to hyperventilate. There has not been time
for metabolic compensation. Answer: 3. A cigarette vendor was brought
to the emergency department of a hospital after she fell into the ground
and hurt her left leg. She is noted to be tachycardic and tachypneic.
Painkillers were carried out to lessen her pain. 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
⩥ C Metabolic Alkalosis, Uncompensated
,The primary disorder is uncompensated metabolic alkalosis (high HCO3
-). As CO2 is the strongest driver of respiration, it generally will not
allow hypoventilation as compensation for metabolic alkalosis. Answer:
4. Ricky's grandmother is suffering from persistent vomiting for two
days now. She appears to be lethargic and weak and has myalgia. She is
noted to have dry mucus membranes and her capillary refill takes >4
seconds. She is diagnosed as having gastroenteritis 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
⩥ B Respiratory Acidosis, Uncompensated
The results show that Mrs. Johansson has respiratory acidosis because of
decreased pH and increased PaCO2 which mean acidic in nature.
Meanwhile, it is uncompensated because HCO3 is within the normal
range. Answer: 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
⩥ C Metabolic Acidosis, Fully Compensated
Baby Angela has metabolic acidosis due to decreased HCO3 and slightly
acidic pH. Her pH value is within the normal range which made the
result fully compensated. Answer: 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 had diarrhea 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
