QUESTIONS AND ANSWERS
One day following posterior spinal fusion surgery a 35 year old female suddenly exhibits
restlessness, labored breathing and acute chest pain. Her heart rate is 122/min., she is afebrile,
and exhibits slightly diminished breath sounds on the right side.
The findings described above should lead the nurse to suspect that the patient has developed:
A. A spontaneous pneumothorax
B. A pulmonary embolus
C. Aspiration pneumonia
D. A pleural effusion - ANS B. A pulmonary embolus

, The nursing staff does not wish to be assigned a difficult patient who continues to demonstrate
disorderly behavior. Which of the following is an acceptable solution?
A. Request the family control the patient's behavior.
B. Transfer the patient
C. The patient assignment should be decided by the Charge Nurse.

assignment among the nursing staff.
A patient who is 72 hours postoperative repair of a bowel obstruction suddenly demonstrates
shortness of breath and his respiratory rate increases from 22 to 45/min. His SpO2 went from
95% to 88% acutely. An arterial blood gas sample obtained while the patient is receiving oxygen
via a nasal cannula at 6L/min reveals the following results:
pH 7.40
pCO2 27
pO2 50
A chest x-ray is obtained and a "ground-glass-like appearance" is reported. Auscultation of the
lungs reveals diffuse crackles that were not present previously.
The findings described above should lead the nurse to believe that the patient has:
A. Acute respiratory distress syndrome
B. A pulmonary embolus
C. A spontaneous pneumothorax
D. Aspiration pneumonia - ANS A. Acute respiratory distress syndrome

A chest x-ray is obtained and a "ground-glass-like appearance" is reported. Auscultation of the
lungs reveals diffuse crackles that were not present previously.
On admission, your patient's arterial blood gas on room air is: pH 7.23, PaCO2 55, PaO2 90,
HCO3 30. The correct arterial blood gas interpretation is:
A. Uncompensated metabolic acidosis
B. Uncompensated respiratory alkalosis
C. Uncompensated respiratory acidosis
D. Uncompensated metabolic alkalosis - ANS C. Uncompensated respiratory acidosis

Your patient just received 10 units of banked blood for a GI bleed. You know this will affect the
oxyhemoglobin dissociation curve by:
A. Shifting it to the right
B. Causing a plateau in the curve
C. Shifting it to the left
D. Causing no change in the curve - ANS C. Shifting it to the left
