Correct Answer � D
Explanation

|
Answer- D Water intoxication
The most probable cause for the above-mentioned symptoms is water intoxication also known as transurethral resection of the prostate (TURP) syndrome.
Absorption of water into the circulation at the time of transurethral urethral resection can lead to :
Hyponatremia, which may manifest as confusion, nausea, and vomiting
Congestive cardiac failure
Hemolysis
Management:
Treatment is by fluid restriction.
Use of isotonic glycine for irrigation during resection reduces the incidence of water intoxication.
