This ob gyn surgical instruments quiz helps you recognize and name common tools used in obstetrics and gynecology. Use it to refresh before skills lab or call, then review anatomy with the female reproductive anatomy quiz, prep for the OR with the perioperative nursing quiz, or explore birth topics with the labor and delivery quiz.

Which instrument is most commonly used to visualize the cervix during a speculum examination?
Sims retractor
Graves speculum
Pederson speculum
Tenaculum
The Graves speculum is designed with wider, curved blades that separate the vaginal walls for optimal cervical visualization. The Pederson speculum is narrower for comfort but less commonly used in routine exams. Other instruments like retractors and tenacula serve different functions.
Which instrument is specifically designed to grasp and stabilize the cervix during procedures?
Ring forceps
Kocher clamp
Tenaculum
Allis clamp
The tenaculum has sharp hooks that hook into the cervical tissue to provide traction and stabilization. Allis and Kocher clamps are used for other tissues and have different tooth patterns. Ring forceps are used for holding gauze or sponges.
Which instrument is used to gradually dilate the cervical canal during gynecologic procedures?
Heaney clamp
Sims retractor
Hegar dilator
Bozeman forceps
Hegar dilators are a set of graduated stainless steel rods designed for incremental dilation of the cervical canal. Heaney clamps are used for vessel ligation, retractors for tissue exposure, and Bozeman forceps for packing sponges.
Which instrument is used to measure the depth and direction of the uterine cavity?
Uterine sound
Sims retractor
Hegar dilator
Endometrial biopsy pipelle
A uterine sound is a slender, graduated probe specifically used to measure uterine depth and orientation. A pipelle samples tissue, dilators expand the cervix, and retractors hold tissue aside.
Which instrument is primarily used to hold surgical sponges during vaginal procedures?
Allis clamp
Uterine curette
Ring forceps
Tenaculum
Ring forceps, also called sponge forceps, have fenestrated jaws designed to securely grip sponges. Tenacula grasp tissue, Allis clamps hold heavier tissue, and curettes scrape tissues.
Which clamp is considered atraumatic and is preferred for grasping delicate structures such as the fallopian tubes or bowel?
Babcock forceps
Kocher clamp
Allis clamp
Heaney clamp
Babcock forceps have smooth, broad, rounded jaws that gently hold delicate tissues without crushing them. Allis and Kocher clamps have toothed jaws and are more traumatic, and Heaney clamps are designed for uterine vessels.
Which instrument is most appropriate for obtaining an endometrial biopsy in an outpatient setting?
Pipelle
Uterine sound
Novak curette
Sharp curette
The Pipelle is a thin, flexible suction device designed to sample endometrial tissue in the office. Curettes are rigid and require dilation, and a uterine sound measures depth but cannot collect tissue.
Which vaginal speculum has narrower, flatter blades and is often used in patients with a narrow vaginal canal?
Tenaculum
Graves speculum
Pederson speculum
Sims retractor
The Pederson speculum features narrower, flatter blades compared to the Graves, making it more comfortable for patients with a narrow introitus. The Graves is broader, and retractors and tenacula serve different purposes.
Which instrument is designed as a uterine manipulator for laparoscopic procedures to mobilize the uterus?
Babcock forceps
Hulka uterine manipulator
Kocher clamp
Ring forceps
The Hulka manipulator attaches to the cervix and allows controlled movement of the uterus during laparoscopy. Forceps and clamps cannot provide the same range of motion or stability required for laparoscopic manipulation.
What is the preferred method for sterilizing reusable stainless steel OB/GYN instruments between procedures?
Ultraviolet light exposure
Glutaraldehyde soak
Steam autoclaving
Dry-heat only
Steam autoclaving reaches high temperatures and pressures that reliably kill all microbial forms on stainless steel instruments. Chemical soaks and UV light are lower-level methods, and dry heat alone is less effective without proper temperature and time controls.
Which retractor is specifically designed for posterior vaginal wall retraction during perineal or vaginal procedures?
Balfour retractor
Sims retractor
Graves speculum
Richardson retractor
The Sims retractor has a single, flat blade bent at the handle and is used to retract the posterior vaginal wall. Richardson and Balfour retract rusty abdominal tissues, and a speculum is for vaginal wall separation, not posterior retraction.
Which instrument features fenestrated jaws specifically for holding sponges in the vaginal canal?
Allis clamp
Foerster sponge forceps
Kocher clamp
Babcock forceps
Foerster sponge forceps have rounded, fenestrated jaws that securely hold sponges for packing or cleaning. Kocher and Allis clamps have teeth for tissue, and Babcock forceps are smooth for delicate tissues.
Which clamp is most appropriate for grasping the fallopian tube during a tubal ligation?
Kelly clamp
Babcock forceps
Kocher clamp
Allis clamp
Babcock forceps grip the tubal tissue atraumatically. Allis and Kocher clamps have injurious teeth, and Kelly clamps are smaller hemostats not ideal for that structure.
Which instrument is designed with a sharp, rigid curette for scraping uterine lining during dilation and curettage?
Novak curette
Heaney clamp
Hegar dilator
Pipelle
The Novak curette has a sharp, hollow, metal tip for precise scraping of endometrial tissue. The Pipelle is a suction device, Hegar dilators expand the cervix, and Heaney clamps ligate vessels.
Before using an electrosurgical unit on a patient, what safety check must be performed?
Inspect blade sharpness
Confirm instrument packaging indicator
Test suture tensile strength
Verify grounding pad placement
Confirming the grounding pad placement reduces the risk of patient burns by ensuring proper current return. Blade sharpness and packaging indicators relate to instruments, and suture tensile tests are irrelevant to electrosurgery.
Which indicator provides immediate visual confirmation that a surgical pack has been exposed to proper autoclave conditions?
Chemical indicator tape
Biological spore test
Autoclave pressure gauge reading
Visual inspection of wrap
Chemical indicator tape changes color when exposed to adequate steam and temperature, providing an immediate visual check. Biological spore tests are definitive but take time. Visual inspection and gauge readings alone do not confirm pack sterilization internally.
Which retractor is most suitable for deep abdominal retraction near the sacral promontory during pelvic surgery?
Sims retractor
Richardson retractor
Deaver retractor
Balfour retractor
The Deaver retractor's large, curved blade is designed for deep retraction of abdominal and pelvic tissues. Sims is for vaginal use, Richardson for shallow exposure, and Balfour is a self-retaining abdominal retractor.
During a colposcopic exam, which instrument is used to grasp and remove small cervical biopsy specimens under magnification?
Uterine sound
Heaney clamp
Tischler biopsy forceps
Pipelle
Tischler biopsy forceps have small jaws ideal for precise, magnified cervical tissue sampling. A Pipelle is a bulk sampling device, a sound measures depth, and a Heaney clamp ligates vessels during hysterectomy.
A uterine sound measures a depth of 8 cm during preoperative assessment. How should this finding be interpreted?
Indicates cervical stenosis
Normal uterine depth
Represents a too shallow measurement
Suggests uterine perforation
A uterine depth of 6 - 9 cm is within the normal range for most adult uteri. A measurement of 8 cm does not indicate perforation, stenosis, or an abnormally shallow uterus.
What feature distinguishes a Kocher clamp from other hemostatic clamps?
Smooth atraumatic jaws
Single interlocking tooth at the tip
Curved ratchet for vessel ligation
Fenestrated jaws for sponge holding
Kocher clamps have a single, robust interlocking tooth at the tip for firm grasping of tough tissue. Fenestrated jaws denote sponge forceps, smooth jaws denote Babcock clamps, and curved ratchets are characteristic of vessel ligating clamps like the Heaney.
