Determine if the client is demonstrating an acidotic (remember: pH less than 7.35) or alkalotic (pH greater than 7.45).
What is the 'primary problem?
If the client is acidotic with aPaC02greater than 45 mmHg
it is RESPIRATORY
If the client is acidotic with a HC03 less than 22 mEq/L it is
If the client is alkalotic with a PaC02 less than 35 mmHg it
If the client is alkalotic with a HC03 greater than 26 mEq/L
it is METABOLIC!
Jean Thomas is a 25-year-old secretary admitted to the emergency room with diaphoresis, hyperventilation, palpitations, and trembling. Jean tells the nurse that she has been "very upset and nervous" over a poor employment evaluation. A tentative diagnosis of acute anxiety episode is made.
Which of the following acid-base imbalances would likely occur as a result of Jean's hyperventilation?
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis
A client recovering from surgery is difficult to arouse following surgery.
The nurse in the PACU has been administering Morphine Sulfate IV to
the client for pain. The client’s respiratory rate is 7 per minute with
shallow breathing. The patient does not respond to any stimuli! The
nurse assesses the ABCs and obtains ABGs STAT! The STAT results
come back from the laboratory and show:
pH = 7.15 Pa C02 = 68 mmHg HC03 = 22 mEq/L
uncompensated respiratory acidosis
pH = 7.52 Pa C02 = 35 mmHg HC03 = 29 mEq/L
The client with severe vomiting is at risk for developing:
