A nurse is caring for a client who reports chest pain. Which of the following laboratory findings indicates myocardial damage?

A. A client who has an ileal conduit and mucus in the pouch - While mucus in the ileal conduit pouch should be monitored, it is not an urgent priority compared to assessing for potential complications such as bleeding in another client.

B. A client who has an arteriovenous fistula that vibrates when palpated - A vibrating arteriovenous fistula indicates normal functioning and does not require immediate assessment.

C. A client who had a transurethral resection of the prostate with red-tinged urine in the bag - Red-tinged urine may indicate bleeding, a potential complication after a transurethral resection of the prostate, requiring prompt assessment and intervention.

D. A client who has chronic kidney disease with cloudy dialysate outflow - While cloudy dialysate outflow may indicate infection or other complications in a client with chronic kidney disease on peritoneal dialysis, it is not as urgent as assessing for bleeding in the client with red- tinged urine.

A. While a blood pressure of 156/90 mm Hg may be elevated, it is not necessarily an indication to withhold propranolol, which is commonly used to treat hypertension.

B. A pulse rate of 54/min suggests bradycardia, which is a potential side effect of propranolol and may warrant withholding the medication.

C. A potassium level of 5.2 mEq/L is within the normal range (3.5-5.0 mEq/L) and is not typically a reason to withhold propranolol.

D. A sodium level of 130 mEq/L is within the normal range (135-145 mEq/L) and is not typically a reason to withhold propranolol.
