5. A 65-year-old man with myasthenia gravis presents A pH 7.20, PaCO2
with severe headache and drowsiness and is diag- 50mmHG, and bicarbon-
nosed with respiratory acidosis. Which of the follow- ate 23 mEq/L
ing arterial blood gas findings would you expect to see
in this patient?
ApH 7.20, PaCO2 50 mm Hg, and bicarbonate 23
mEq/L
BpH 7.25, PaCO2 40 mm Hg, and bicarbonate 20
mEq/L
CpH 7.55, PaCO2 30 mm Hg, and bicarbonate 24
mEq/L
, DpH 7.60, PaCO2 40 mm Hg, and bicarbonate 28

6. A 32-year-old man is admitted to the hospital for fever A metabolic acidosis
and severe pain in his right finger. The patient cut his
finger with a hedge trimmer 4 days ago and did not
seek medical treatment. He has been taking ibuprofen
at home. Vital signs are T 39.1°C (102.4°F), BP 88/58
mm Hg, HR 110 bpm, RR 26 breaths per minute, and
pulse oximetry 97% on room air. Physical examination
is significant for a 2 cm laceration over the distal in-
terphalangeal joint of the right index finger. Hand ra-
diographs are significant for a nondisplaced, oblique
fracture of the distal phalanx of the right index finger.
Arterial blood gas values are as follows:
pH: 7.15
pCO2: 36 mm Hg
HCO3: 12 mmol/L
Anion gap: 32 mEq/L
Which of the following acid-base disorders best de-
scribes the patient's condition?
AMetabolic acidosis
BMetabolic alkalosis
CRespiratory acidosis
DRespiratory alkalosis
