The CDC has identified three new standard precautions for infection control. Which of the following clinical situations is addressed by these new precautions?
 
  A) A client is scheduled for a lumbar puncture to assess for meningitis.
  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

A patient has been admitted to the cardiac unit with the diagnosis of bradycardia. The patient states I am confused about what the doctor said is wrong with me, he said my pacemaker is not working. I don't have a pacemaker.
 
   What is the nurse's best response? a. The sinoatrial node is the pacemaker' of your heart.
  b. Myocardial contractility determines your heart rate.
  c. The atrioventricular node is the pace-maker' of your heart.
  d. The ventricular Purkinje network deter-mines your heart rate.

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.

Both answers were spot on, thank you once again
