already in the virtual hospital from a previous exercise, click on Leave the Floor and
then on Restart the Program to get to the sign-in window.)
• From the Patient List, select Jacquline Catanazaro (Room 402).
• Click on Go to Nurses’ Station.
• Click on Chart and then on 402.
• Click on History and Physical.
Exercise 2 - Question 1
Is there anything in Jacquline Catanazaro’s history that would put her at risk for an acid-base
imbalance?
Question 2
Not yet graded / 1 pts
• Click on Return to Nurses’ Station.
• Click on 402 at the bottom of your screen.
• Click on Patient Care and then on Nurse-Client Interactions.
• Select and view the video titled 0730: Intervention—Airway. (Note: Check the virtual
clock to see whether enough time has elapsed. You can use the fast-forward feature to
advance the time by 2-minute intervals if the video is not yet available. Then click again
on Patient Care and Nurse-Client Interactions to refresh the screen.)
Exercise 2 - Question 2
Based on Jacquline Catanazaro’s history, what would the nurse expect to be causing her
respiratory distress?
Shortness of breath
Asthma exacerbation

Exercise 2 - Question 5
Document the results of Jacquline Catanazaro’s ABG on Wednesday at 0730.
Bicarb: 24
Question 6

Exercise 2 - Question 6
How would you interpret the results documented in questions 4 and 5? Is the acid-base
imbalance compensated or uncompensated (fully or partially)? Explain your answer.
denoting acidosis. The PaCO2 is slightly above normal (35-45), also denoting acidosis. The
bicarb is within normal limits (21-28); it takes 24-48 hours for the renal system to begin to
compensate for acidosis.
Wednesday: Fully compensated respiratory acidosis. The pH is at the lower limit of normal, but
the PaCO2 is increased with the bicarb remaining within normal limits. It is fully compensated
because the pH is within normal limits.
Question 7

Exercise 2 - Question 7
Based on the acute aspect of Jacquline Catanazaro’s respiratory difficulties, what lines of defense
would you expect to be working to compensate for her respiratory acidosis?.
Question 8
Not yet graded / 1 pts
Exercise 2 - Question 8
If the patient’s electrolyte results were available, what might you expect her potassium levels to
be? Provide a rationale for your answer.
The potassium may be elevated. In acidosis, the extracellular hydrogen ion content increases, and
the hydrogen ions move into the intracellular fluid. To keep the intracellular fluid electrically
neutral, an equal number of potassium ions leave the cell, creating a relative hyperkalemia. If the
acidosis is chronic, the kidneys have time to compensate for the excess hydrogen and
hyperkalemia does not occur.

Exercise 2 - Question 9
Based on Jacquline Catanazaro’s medical diagnosis, what is the underlying pathophysiologic
problem leading to the respiratory acidosis?
Question 10
Not yet graded / 1 pts
• Click on Return to Room 402.
• Click on Patient Care and then Physical Assessment.
• Complete a physical assessment for Jacquline Catanazaro by clicking on the body system
categories (yellow buttons) and subcategories (green buttons).
Exercise 2 - Question 10
Record the findings of your physical assessment below.
• Mental status
• Musculoskeletal
• Cardiovascular
• Respiratory
• Integumentary
Mental status: Alert and oriented x 3. Perceptual ability slightly impaired. Agitated and anxious.
Musculoskeletal: Full range of movement. Moves all extremities equally. Reflexes intact.
Cardiovascular: Apical pulse regular. No JVD. S1 and S2 normal.
Respiratory: Labored and shallow respiratory effort. Tachypneic. Crackles in right lower lobes,
wheezes throughout. Productive cough with white frothy sputum. Substernal retractions and use
of neck muscles.
Integumentary: Skin warm and moist with flushed color.
Question 11

Exercise 2 - Question 11
Are there any clinical manifestations of respiratory acidosis? If so, please describe. If not, how
do you explain?
Question 12
Not yet graded / 1 pts
• Click on Take Vital Signs.
Exercise 2 - Question 12
What is the patient’s respiratory rate? How does this correlate with her respiratory acidosis?
Question 13
Not yet graded / 1 pts
Exercise 2 - Question 13
If Jacquline Catanazaro’s pH were 7.2, how might her physical assessment differ? Document the
expected clinical manifestations of respiratory acidosis below.
• Neurologic
• Musculoskeletal
• Cardiovascular
• Respiratory
• Integumentary
Neurologic: Lethargy, confusion, stupor, coma
Musculoskeletal: Hyporeflexia, skeletal muscle weakness, flaccid paralysis
Cardiovascular: Bradycardia, tall, peaked T waves; widened QRS complexes, prolonged PR
interval; heart blocks, hypotension, thready peripheral pulses
Respiratory: Variable, ineffective respirations
Integumentary: Pale to cyanotic mucous membranes
Question 14
Not yet graded / 1 pts
• Click on Chart.
• Click on 402 for Jacquline Catanazaro’s chart.
• Click on Physician’s Orders.
Exercise 2 - Question 14
Look at the most recent physician’s orders. What medication is ordered to treat the respiratory
acidosis? What is the medication’s underlying mechanism of action to correct the acidosis?
Albuterol 5 mg via nebulizer x 1 STAT—this is a bronchodilator, which will relieve the airway
obstruction caused by the asthma. Dilating the bronchi will increase air movement and gas
exchange at the alveolar level, thus increasing CO2 excretion and raising the patient’s pH to
normal.
