A nurse is caring for a client diagnosed with chronic renal disease. The nurse should recognize that which of the following medications is contraindicated for clients with chronic renal disease?

A. Heart rate of 90 bpm: While an elevated heart rate may be expected in response to burn injury and the body's stress response, a heart rate of 90 bpm alone may not be concerning without additional context.

B. Blood pressure of 96/50 mm Hg: This blood pressure reading indicates hypotension, which can be a sign of inadequate tissue perfusion, fluid loss, or shock. It requires prompt notification of the healthcare provider for further assessment and intervention.

C. Urine output of 2 mL/kg per hour: Adequate urine output is important for renal function and fluid balance, and a urine output of 2 mL/kg per hour is within the normal range. While changes in urine output should be monitored, this finding alone does not require immediate notification of the healthcare provider.

D. Pain rating of 7 on a 1 to 10 point scale: Pain management is important in burn care, but a pain rating of 7 on a 1 to 10 scale is not unusual in clients with burns and may not require immediate notification of the healthcare provider unless accompanied by other concerning symptoms.

A. Complete Heart Block: Complete heart block (third-degree AV block) occurs when there is no communication between the atria and ventricles. The atria and ventricles beat independently, resulting in a very slow ventricular rate. This rhythm is characterized by regular P waves that have no relation to the QRS complexes.

B. Sinus Tachycardia: Sinus tachycardia is a rhythm originating from the sinoatrial node with a heart rate typically between 100-150 beats per minute. The rhythm is regular, and the P waves precede each QRS complex consistently.

C. Ventricular Tachycardia: Ventricular tachycardia is a fast heart rhythm that originates from the ventricles. It is characterized by wide and abnormal QRS complexes with a rate usually between 150-250 beats per minute. There may be no visible P waves, and if present, they are not associated with the QRS complexes.

D. Idioventricular Rhythm: Idioventricular rhythm is a slow rhythm originating from the ventricles with a heart rate usually between 20-40 beats per minute. It has wide and abnormal QRS complexes and no visible P waves.
