  B) A client will undergo a screening colonoscopy for colorectal cancer.
  C) A client will be placed in a room that will be shared with other clients.
  D) A client will have her appendix removed laparoscopically (without a linear incision).

Question 2

Answer to Question 1

A
Feedback:
The CDC's three new standard precautions for infection control address Respiratory Hygiene/Cough Etiquette, Safe Injection Practices, and Practices for Special Lumbar Puncture Procedures. These particular precautions do not address surgery, endoscopies, or room sharing.

Answer to Question 2

A
The conduction system originates with the sinoatrial node, the pacemaker of the heart. Elec-trical impulses are then transmitted along intraatrial pathways to the atrioventricular (AV) node. The AV node mediates impulse transmission between the atria and the ventricles. Delaying the impulse at the AV node before transmitting it through the bundle of His and ventricular Purkinje network. The heart rate is regulated by the sympathetic and parasympathetic systems, not by myocardial contractility and ventricular Purkinje network. Myocardial contractility is the ability of the heart to squeeze blood from the ventricles and prepare for the next contraction. This is dif-ficult to measure because preload, afterload, and heart rate must remain constant.
