,1. Which of the following is the wound classification for a bronchoscopy?
A. Clean
B. Contaminated
C. Dirty and infected
D. Clean-contaminated
Correct Answer: D. Clean-contaminated
Rationale: Clean-contaminated (Class II) wounds occur when an incision or
procedure enters a controlled, populated tract with normal flora without
unusual contamination. These tracts include the respiratory, alimentary,
genital, or urinary tracts. A bronchoscopy enters the respiratory tract under
controlled conditions, making it Class II.
2. Which of the following structures is located in the alveolar processes?
A. Teeth
B. Sinuses
C. Tonsils
D. Villi
Correct Answer: A. Teeth
Rationale: The alveolar processes are the thickened ridges of bone on the
maxilla and mandible that contain the dental sockets (alveoli) housing the roots
of the teeth.
3. The enzyme used to soften the zonules of the lens before cataract surgery is:
A. Atropine sulfate
, B. Alpha-chymotrypsin
C. Acetylcholine chloride
D. Pilocarpine hydrochloride
Correct Answer: B. Alpha-chymotrypsin
Rationale: Alpha-chymotrypsin is a proteolytic enzyme that dissolves/digests
the zonules of Zinn (suspensory ligaments) holding the crystalline lens in
place, facilitating intracapsular cataract extraction.
4. When perforated metal trays are placed on the shelves of the steam sterilizing
cart, they should be positioned:
A. Flat
B. Upside down
C. Vertical
D. Angled
Correct Answer: A. Flat
Rationale: Perforated trays are designed to lie flat on sterilizer cart shelves to
allow even steam distribution and proper air displacement through the
perforations, preventing condensate accumulation.
5. How should the stretcher be oriented when necessary to use an elevator to
transport a patient to the OR?
A. Place stretcher sideways in elevator
B. Enter head first, exit feet first
C. Position in elevator is irrelevant
, D. Enter feet first, exit head first
Correct Answer: B. Enter head first, exit feet first
Rationale: When entering an elevator, the patient is pushed in head first so
that the patient's head remains protected against sudden stops and the handler
at the head retains control. This orientation ensures that when exiting, the
patient leaves feet first, providing the handler a view of the exit pathway.
6. Which of the following is a curved, transverse incision across the lower abdomen
frequently used in gynecological surgery?
A. Midline
B. Paramedian
C. McBurney's
D. Pfannenstiel
Correct Answer: D. Pfannenstiel
Rationale: The Pfannenstiel incision is a curved, transverse incision made
through the skin and subcutaneous tissue roughly 2 to 3 cm above the pubic
symphysis. It provides good exposure to pelvic organs and offers cosmetic
benefits.
7. Hyperkalemia is a high concentration of:
A. Calcium
B. Nitrogen
C. Potassium
D. Albumin
