A nurse is caring for a postoperative client. The nurse should base the client's pain management interventions primarily on which methods of determining the intensity of the client's pain?
The patient's chart
Visual observation for nonverbal signs of pain
The client's self-report of pain severity
The nature and invasiveness of the surgical procedure
The Correct Answer is C
A. The patient's chart may provide historical information but does not reflect the current pain intensity the client is experiencing.
B. Visual observation for nonverbal signs of pain can be useful, especially for nonverbal patients, but self-reporting is the most accurate measure of pain intensity.
C. The client's self-report of pain severity is the gold standard for assessing pain intensity, as it reflects the individual’s personal experience of pain.
D. While the nature and invasiveness of the surgical procedure can provide context for expected pain levels, they do not replace the importance of the client's self-report in managing pain effectively.

B. Urinary retention involves the inability to empty the bladder fully but does not specifically present with cloudy urine, odor, or blood.

Correct Answer is C
Explanation
A. Metabolic alkalosis is characterized by a high pH and elevated bicarbonate levels, which is not present in these results.
B. Respiratory alkalosis would present with an increased pH and decreased PaCO2, which does not apply here.
C. The low pH (7.12) indicates acidemia, and the elevated PaCO2 (90 mm Hg) suggests hypoventilation and respiratory acidosis due to CO2 retention. The bicarbonate level is within normal limits, further supporting respiratory acidosis.
D. Metabolic acidosis would be indicated by a low pH and low bicarbonate levels; however, the bicarbonate is normal in this case, ruling out metabolic acidosis.
