A nurse is monitoring a client following a coronary angiography. Which of the following findings should the nurse report to the provider?
BUN 30 mg/dL
Sinus rhythm 95/min on a cardiac monitor
Respiratory rate 12/min
PTT 25 seconds
The Correct Answer is A
Choice A reason: BUN or blood urea nitrogen 30 mg/dL is above the normal range of 10 to 20 mg/dL and indicates renal impairment or dehydration, which can be caused by contrast dye used during coronary angiography or blood loss during or after the procedure. The nurse should report this value to the provider and monitor the client for signs of acute kidney injury, such as oliguria, edema, or electrolyte imbalances.
Choice B reason: Sinus rhythm 95/min on a cardiac monitor is within the normal range of 60 to 100/min and does not indicate any cardiac arrhythmia or ischemia.
Choice C reason: Respiratory rate 12/min is within the normal range of 12 to 20/min and does not indicate any respiratory distress or hypoxia.
Choice D reason: PTT or partial thromboplastin time 25 seconds is within the normal range of 25 to 35 seconds and does not indicate any bleeding disorder or anticoagulant therapy.

Correct Answer is A
Explanation
Choice A reason: Urinating before and after sexual intercourse can help flush out any bacteria that may have entered the urinary tract during sexual activity, and prevent them from causing an infection.

Choice B reason: Increasing milk consumption to make the urine more alkaline is not a recommended instruction, as it may increase the risk of developing kidney stones or calcium deposits in the urinary tract.
Choice C reason: Emptying the bladder at least every 4 hours is a good practice, but not sufficient to prevent urinary tract infections. The nurse should also advise the client to drink plenty of fluids, especially water, to dilute the urine and flush out bacteria.
Choice D reason: Using vaginal douche once a week is not a recommended instruction, as it may alter the normal flora of the vagina and increase the risk of infection. The nurse should advise the client to avoid using any products that may irritate the genital area, such as perfumed soaps, sprays, or powders.
Choice E reason: Drinking cranberry juice daily is not a proven method to prevent urinary tract infections, although some studies suggest that it may have some benefits. The nurse should inform the client that cranberry juice may interact with some medications, such as warfarin, and that it may also increase the acidity of the urine, which can cause discomfort or burning sensation.
Correct Answer is A
Explanation
The correct answer is A:
Choice A reason:
Replace the unit when the drainage chamber is full. This ensures continuous, effective drainage. A full chamber cannot collect more fluid, risking system compromise and patient safety.
Choice B reason:
Pinning the tubing to the bed sheets is incorrect because it can cause kinks in the tubing, leading to obstruction of drainage and potential complications.
Choice C reason:
Monitoring for at least 150 mL of drainage every hour is not a standard practice. Normal chest tube drainage is variable; excessive drainage, such as 150 mL/hour, could indicate a serious condition like hemorrhage.
Choice D reason:
Clamping the tube routinely for 30 minutes every 8 hours is not recommended. Clamping may be done during tube removal or to check for air leaks but doing so routinely can lead to tension pneumothorax.
