Correct Answer is B

Explanation

Choice A reason:

Removing the NG tube without further attempts to unclog it may not be necessary and could be an unnecessary intervention.

Choice B reason:

This statement is correct. Attempting to unclog the NG tube with warm water and an in-and-out motion is an appropriate next step.

Choice C reason:

Flicking the tube with the fingers may not be effective in dislodging the clog, and it could potentially cause harm to the patient.

Choice D reason:

Withdrawing the tube 3 to 5 cm may not effectively address the clog and could potentially lead to complications.

A. Sudden thirst, unrelieved by oral fluid administration B. Tachycardia, hypotension, and tachypnea C. Diaphoresis and sudden onset of abdominal pain D. Tarry, foul-smelling stools

Correct Answer is B

Explanation

Choice A reason:

While thirst can be a sign of dehydration, it is not specific to recurrence of a GI bleed.

Choice B reason:

This is the correct answer. Tachycardia (rapid heart rate), hypotension (low blood pressure), and tachypnea (rapid breathing) are signs of potential recurrence of a GI bleed and should be closely monitored.

Choice C reason:

Diaphoresis (excessive sweating) and sudden onset of abdominal pain could be indicative of various conditions, but they are not specific to recurrence of a GI bleed.

Choice D reason:

Tarry, foul-smelling stools are indicative of melena, which is a sign of a GI bleed. However, in this scenario, the bleeding has been controlled, so this is not an expected sign of recurrence.
