The MD schedules an ultrasonic lithotripsy.
Choose the correct description of this procedure.
An incision into the renal pelvis for stone removal.
An incision into the kidney to remove a stone.
A procedure used to break up stones, thus allowing them to pass from the urinary tract.
A minimally invasive technique using laser technology to fragment stones.
The Correct Answer is C
Choice A rationale
Incisions into the renal pelvis for stone removal describe open surgical methods, not ultrasonic lithotripsy. This invasive approach is reserved for cases where less invasive techniques fail or stones are inaccessible through standard methods. Lithotripsy avoids direct incisions, utilizing external energy for stone fragmentation.
Choice B rationale
Kidney incisions for stone removal align with nephrolithotomy procedures rather than ultrasonic lithotripsy. This alternative represents open surgical intervention, distinct from non-invasive lithotripsy technologies. Lithotripsy eliminates stones using sound waves or lasers, reducing surgical risks and recovery times.
Choice C rationale
Ultrasonic lithotripsy employs high-frequency sound waves to break stones into small fragments. This minimally invasive method allows natural passage through the urinary tract or facilitates removal via catheterization. It reduces complications compared to invasive surgeries and is highly effective for calculi management.
Choice D rationale
Laser fragmentation techniques differ from ultrasonic lithotripsy, involving concentrated light energy to break stones. While both are minimally invasive, ultrasonic methods utilize sound waves rather than light energy for disintegration. This technical distinction outlines lithotripsy's use of external sound waves for stone management.

Correct Answer is C
Explanation
Choice A rationale
Low urine output could be due to dehydration, medication effects, or stress. While it warrants further assessment, it is not typically associated with immediate life-threatening complications in the context of PUD.
Choice B rationale
Vomiting after a meal can occur in PUD due to delayed gastric emptying or irritation. However, it does not immediately indicate a complication requiring urgent follow-up unless accompanied by other symptoms such as severe pain or hematemesis.
Choice C rationale
Blood in the stool may indicate gastrointestinal bleeding, a serious complication of PUD. This finding requires immediate evaluation to determine the source and extent of bleeding, as it can lead to hypovolemic shock if untreated.
Choice D rationale
Abdominal discomfort is common in PUD due to gastric irritation or acid-related issues. While it requires management, it does not typically signal an urgent complication unless associated with other alarming symptoms.
Correct Answer is A
Explanation
Choice A rationale
A bland diet reduces gastric irritation by avoiding substances that stimulate acid secretion or exacerbate nausea. It includes foods like rice, bananas, and toast that are easy to digest and less likely to provoke symptoms of nausea or vomiting.
Choice B rationale
Opposing the bland diet recommendation for severe nausea ignores scientific evidence that supports its use. Providing a diet rich in spices or acidic foods can worsen symptoms by irritating the gastrointestinal tract further. .
