Which instrument is used to retract tissue edges and improve visualization of the surgical field?
Answer: Gelpi retractor
A Gelpi retractor is a self-retaining retractor that holds tissue edges apart to improve surgical exposure without requiring an assistant to hold them.
What is the correct order for putting on sterile surgical attire after performing a surgical scrub?
Answer: Gown, gloves, mask
After scrubbing, the gown is donned first, then sterile gloves are applied to maintain sterile technique throughout the process.
In a complete blood count (CBC), which cell type is elevated during a bacterial infection?
Answer: Neutrophils
Neutrophils are the primary white blood cells that respond to bacterial infection, and their count is typically elevated (neutrophilia) during such infections.
Which of the following is a sign that a surgical instrument has been contaminated and must be replaced or re-sterilized?
Answer: The pack wrap is intact but damp or wet
A wet or damp pack after autoclaving is considered contaminated because moisture allows microorganisms to wick through the packaging material.
A urinalysis reveals a urine specific gravity of 1.008 in a dog. What does this finding most likely indicate?
Answer: Isosthenuric urine suggesting impaired renal concentrating ability
A specific gravity of 1.008–1.012 is isosthenuric, meaning the kidneys are producing urine at the same concentration as the glomerular filtrate, indicating impaired concentrating ability.
Which instrument is specifically designed to clamp and ligate blood vessels during surgery?
Answer: Rochester-Carmalt forceps
Rochester-Carmalt forceps are large crushing clamps used to occlude blood vessels and pedicles before ligation during surgery.
What is the primary purpose of performing a Gram stain on a laboratory sample?
Answer: To differentiate bacteria based on cell wall composition
A Gram stain differentiates bacteria into gram-positive (purple) and gram-negative (pink/red) categories based on differences in their cell wall composition.
