111. A common donor site for an autogenous bone graft is

Femur

Pelvis

Ilium

Ischium

The ilium is a common donor site for an autogenous bone graft. This is because the ilium is a flat and relatively large bone located in the pelvis, which makes it suitable for harvesting bone grafts. The ilium provides a good amount of bone material that can be used for grafting procedures, such as in spinal fusion surgeries or reconstructive procedures. Its accessibility and the quality of bone make it a preferred choice as a donor site for autogenous bone grafts.

112. The laser used primarily for port-wine stain lessons of the skin is the

Argon

Krypton

Yttrium aluminum garnet (YAG)

Ruby

The ruby laser is commonly used for port-wine stain lesions of the skin. This type of laser emits pulses of red light that are specifically absorbed by the blood vessels in the skin, causing them to heat up and coagulate. This helps to reduce the appearance of the port-wine stain by shrinking the blood vessels. The ruby laser has been found to be effective in treating this condition, making it the correct answer.

113. Balloon angioplasty is accomplished with the use of a __________ catheter.

Gruntzig

Gibbons

Garceau

Harris

Balloon angioplasty is a procedure used to open blocked or narrowed blood vessels. It involves the use of a catheter with a balloon at the tip. The balloon is inflated to compress the plaque against the vessel walls, widening the vessel and restoring blood flow. The correct answer, Gruntzig, refers to Andreas Gruntzig, a Swiss cardiologist who developed and popularized balloon angioplasty in the 1970s. Therefore, a Gruntzig catheter would be the appropriate choice for performing this procedure.

114. The risks of cone biopsy are minimized by using the

Cervitome

Cold knife

Scalpel

CO2 laser

The use of a CO2 laser minimizes the risks of cone biopsy because it provides precise and controlled cutting. The laser beam can be focused on a specific area, allowing for minimal damage to surrounding tissues. Additionally, the CO2 laser cauterizes blood vessels as it cuts, reducing bleeding during the procedure. This results in less postoperative pain, faster healing, and reduced risk of infection compared to other methods such as cervitome or cold knife.

115. A temporary biologic dressing is

Porcine

Telfa

Collagen

Mesh

A temporary biologic dressing refers to a type of dressing that is used for a short period of time to protect and promote healing of a wound. In this case, the correct answer is "porcine," which means that the dressing is made from pig tissue. Porcine dressings are commonly used in wound care due to their biocompatibility and ability to provide a moist environment for wound healing. They can help to control bleeding, reduce pain, prevent infection, and promote tissue regeneration.

116. Laser surgery performed in the rectal area should be preceded by

Suctioning of lower bowel to remove methane gas

Suctioning out the lower bowel contents

Packing the rectum with dry, counted sponges

A and C

Laser surgery performed in the rectal area should be preceded by suctioning of the lower bowel to remove methane gas. This is because methane gas, which is produced by bacteria in the colon, can be ignited by the laser, potentially causing an explosion or fire. Therefore, it is important to remove the methane gas before performing laser surgery in order to ensure the safety of the patient and the surgical team.

117. Each are measures to prevent heat loss in newborn, or children in the OR EXCEPT

Hypothermia blanket is prepared

Water mattress is warmed

Webril is wrapped on extremities

Solutions for skin prep and intraoperative use are warmed

The given options describe measures to prevent heat loss in newborns or children in the operating room. The options include warming a water mattress, wrapping webril on extremities, and warming solutions for skin prep and intraoperative use. The correct answer states that preparing a hypothermia blanket is not a measure to prevent heat loss. This implies that using a hypothermia blanket does not help in maintaining the body temperature of the newborn or child.

118. A laminaria tent is used to

Suction uterine contents

Close cervix

Dilate cervix

Visualize uterus

A laminaria tent is a medical device used to dilate the cervix. It is typically made of dried seaweed and is inserted into the cervix. As it absorbs moisture, it swells and gradually expands the cervix, allowing for easier access to the uterus. This procedure is commonly performed before certain gynecological procedures such as surgical abortions or the placement of an intrauterine device (IUD). Therefore, the correct answer is "dilate cervix".
