An average range for activated partial thromboplastin time (PTT) is: - Answer-25-35 seconds. PTT is a lab measure of blood coagulation. What is the correct angle of insertion for placing a butterfly needle into a vein for intravenous administration of a contrast agent? - Answer-15 degrees It's also important that the vein be properly stabilized and needle be inserted gently with bevel facing upward. A total volume of 125 mL of an iodinated contrast agent is administered intravenously via ...

The use of water as an oral contrast material for CT of the abdomen and/or pelvis has several potential advantages, including: 1. increased palatability and improved pt comfort 2. better demonstration of enhancing bowel wall 3. no interference with 3D applications CORRECT ANSWER-1, 2, and 3 The use of water as a neg contrast agent is becoming increasingly common for many CT applications for the abdomen and pelvis A pt's BP is measured 140/70 mm Hg. The number 140 represents: a. pressu...
