What is the main pharmacological concern after performing a paracentesis?
Tachycardia
Hyperglycemia
Bowel Changes
Hypotension
The Correct Answer is D
Rationale:
A. Tachycardia may occur secondary to hypotension, but it is a secondary concern, not the primary pharmacological issue.
B. Paracentesis does not directly affect blood glucose levels.
C. While changes in bowel habits may occur with fluid shifts, they are not the primary concern after paracentesis.
D. Removal of large volumes of ascitic fluid can lead to intravascular volume depletion, resulting in hypotension. Monitoring blood pressure before, during, and after the procedure is essential, and volume replacement may be required to maintain hemodynamic stability.

Rationale:
A. Seizures are more commonly associated with severe electrolyte imbalances like hyponatremia, not mild hypokalemia.
B. Neurogenic shock is related to spinal cord injury, not potassium imbalance.
C. Hypokalemia (potassium 3.3 mEq/L; normal 3.5–5.0 mEq/L) increases the risk of ventricular arrhythmias, palpitations, and potentially life-threatening cardiac complications, especially in clients taking diuretics like furosemide.

Correct Answer is D
Explanation
Rationale:
A. Percutaneous Transhepatic Cholangiography (PTC) involves inserting a needle through the skin into the liver to visualize bile ducts, not using endoscopy.
B. Endoscopic Ultrasound (EUS) uses an endoscope with ultrasound to image structures near the GI tract but does not combine with radiographic imaging of the ducts.
C. Magnetic Resonance Cholangiopancreatography (MRCP) uses MRI to noninvasively visualize bile and pancreatic ducts, without endoscopy.
D. Endoscopic Retrograde Cholangiopancreatography (ERCP) combines endoscopy with radiographic imaging to examine the bile and pancreatic ducts, allowing both diagnosis and therapeutic interventions.
