Correct Answer is A

Explanation

A. This description is indicative of possible myocardial infarction (MI), a life-threatening emergency. Immediate evaluation and intervention, such as administering oxygen, obtaining an EKG, and providing pain relief, are crucial to prevent further damage to the heart and reduce mortality.

B. Moderate pain worse on inspiration suggests pleuritic pain, often associated with conditions like pleuritis or pulmonary embolism, which are serious but generally not as immediately life-threatening as an MI.

C. Cramping substernal pain may indicate a gastrointestinal issue, such as gastroesophageal reflux disease (GERD), which is less urgent than a potential MI.

D. A dull ache may be related to musculoskeletal or gastrointestinal issues and does not suggest the immediate need for intervention seen in MI.

A. Hydration and urine output are maintained by bladder irrigation. B. Bladder irrigation prevents obstruction of the catheter after surgery. C. Bladder irrigation decreases the risk of postoperative bleeding. D. Antibiotics are infused continuously through the bladder irrigation.

Correct Answer is B

Explanation

A. Hydration and urine output are maintained through IV fluids and kidney function, not bladder irrigation.

B. Continuous bladder irrigation prevents catheter obstruction by flushing out blood clots or debris after TURP surgery. This is the primary purpose of the procedure.

C. While bladder irrigation may help reduce bleeding indirectly by maintaining flow, it is not its main purpose.

D. Antibiotics are not typically administered via bladder irrigation; systemic routes are preferred for infection control.
