Heart failure clients have distinct signs and symptoms associated with the disease. Most drugs focus improving which characteristic of heart function?
1. Blood pressure
2. Heart rate
3. Contractility
4. Electrical impulse conduction
3
Rationale 1:Blood pressure is not one of the focuses of primary characteristics of heart failure.
Rationale 2:The ability of the heart rate to speed up or slowdown is the second characteristic important to pharmacology.
Rationale 3: Contractility or the strength of contraction is the most important characteristic of heart failure. The fundamental cause of heart failure is a weak myocardium, causing the muscle to beat more forcefully is the ideal solution.
Rationale 4:Impulse conduction speed is the third fundamental characteristic of cardiac physiology.
Global Rationale: The ability to change the force of contraction, or contractility is of particular interest in the pharmacotherapy of heart failure. Because the fundamental cause of heart failure is a weak myocardium, causing the muscle to beat more forcefully is the ideal solution. The ability to increase the strength of contraction is called a positive inotropic effect.

The patient is on postoperative day 1 after having undergone a TURP procedure. He has continuous bladder irrigation (CBI). Actual urine output during continuous bladder irrigation is calculated by:
a. measuring and recording all fluid output in the drainage bag. b. measuring the total output and deducting the total of the irrigating and intravenous solutions. c. adding the total of the intravenous and irrigating solutions and then deducting the amount of output. d. measuring total output and deducting the amount of irrigating solution used.
