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: Oxybutynin is an anticholinergic drug that relaxes the muscles of the bladder and reduces spasms, urgency, and frequency of urination. It is used to treat overactive bladder and urinary incontinence.
Choice B reason: Oxybutynin does not increase tissue perfusion in the lungs, as it has no effect on the respiratory system. It can actually cause dry mouth, nasal congestion, and blurred vision as side effects.
Choice C reason: Oxybutynin does not increase venous return to the heart, as it has no effect on the cardiovascular system. It can actually cause tachycardia, palpitations, and hypertension as side effects.
Choice D reason: Oxybutynin does not relax the muscles of the colon, as it has no effect on the gastrointestinal system. It can actually cause constipation, nausea, and abdominal pain as side effects.
Correct Answer is A
Explanation
Choice A reason: HbA1c or glycated hemoglobin is a measure of average blood glucose levels over the past 2 to 3 months. A lower HbA1c indicates better glycemic control and a lower risk of diabetes complications. The target HbA1c for most people with diabetes mellitus is less than 7%.
Choice B reason: HbA1c 12.5% is very high and indicates poor glycemic control and a high risk of diabetes complications, such as retinopathy, nephropathy, or neuropathy.
Choice C reason: Fasting blood glucose 100 mg/dL is within the normal range of 70 to 99 mg/dL and indicates normal glucose metabolism, but it does not reflect the long-term control of blood glucose levels over the past 3 months.
Choice D reason: Fasting blood glucose 70 mg/dL is at the lower end of the normal range and may indicate hypoglycemia or low blood glucose levels, which can cause symptoms such as sweating, trembling, hunger, or confusion.
