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.

Correct Answer is B
Explanation
Rationale:
A. High fat content does not directly cause refeeding syndrome; fat is less likely to trigger the electrolyte shifts seen in this condition.
B. Rapid reintroduction of carbohydrates in malnourished patients stimulates insulin release, which drives phosphate, potassium, and magnesium into cells, leading to potentially life-threatening electrolyte imbalances—the hallmark of refeeding syndrome.
C. Excess protein intake can strain kidney function but is not the primary cause of refeeding syndrome.
D. Vitamin deficiencies, such as thiamine, can worsen complications, but the immediate trigger is the rapid carbohydrate load.
Correct Answer is A
Explanation
Rationale:
A. A nasogastric (NG) tube is often used to decompress the stomach in conditions like pyloric obstruction. By removing accumulated gastric secretions and gas, it relieves pressure, nausea, and vomiting and prevents further distention.
B. While NG tubes can be used to administer medications, this is not the primary purpose in the treatment of a pyloric obstruction.
C. Supplying nutrients via tube feedings is typically done with a feeding tube, not for gastric decompression in obstruction.
D. Determining the pH of gastric secretions may be performed for diagnostic purposes, but it is not the main rationale for using an NG tube in this situation.
