Free NBSTSA Trivia Questions and Answers — Questions and Answers
Question 1: Which section of the small intestine is the first?
- fistula
- duodenum (Correct answer)
- cerumen
- love
Correct answer: duodenum
The small intestine is divided into three distinct sections, and the duodenum is the very first part. It receives partially digested food, known as chyme, from the stomach. The duodenum plays a critical role in digestion by mixing chyme with digestive enzymes from the pancreas and bile from the liver.
Question 2: Which of the following uses a binocular microscope to examine the cervix?
- trauma
- colposcopy (Correct answer)
- atherosclerosis
- acute
Correct answer: colposcopy
Colposcopy is a medical procedure that utilizes a colposcope, which is a specialized binocular microscope, to provide a magnified view of the cervix, vagina, and vulva. This allows healthcare professionals to closely examine these tissues for any abnormal cells or lesions. It is commonly performed to investigate abnormal Pap test results.
Question 3: Which middle ear ossicle has the oval window covered?
- parasitism
- stapes (Correct answer)
- 85
- daily
Correct answer: stapes
The stapes, also known as the stirrup, is the smallest of the three middle ear ossicles (malleus, incus, stapes). It articulates with the incus and its footplate fits into the oval window of the inner ear. The stapes transmits sound vibrations from the incus to the fluid-filled inner ear, which is a crucial step in the process of hearing.
Question 4: When a patient is lying flat, where should the safety strap be fastened?
- pharynx and trachea
- over the thighs (Correct answer)
- after each case
- Ampulla of Vater
Correct answer: over the thighs
When a patient is positioned flat on the operating table, the safety strap should be securely fastened over the patient's thighs, typically about 2 inches above the knees. This placement helps to safely secure the patient to the table, preventing accidental movement or falls during the surgical procedure. It ensures patient stability without impeding circulation or respiration.
Question 5: How are rickettsial diseases passed on?
- arthropod bites (Correct answer)
- cancer procedures
- kidney pedicle
- lukewarm water
Correct answer: arthropod bites
Rickettsial diseases are a group of infections caused by Rickettsia bacteria, which are obligate intracellular parasites. These diseases are primarily transmitted to humans through the bites of infected arthropods, such as ticks, fleas, lice, and mites. These arthropods act as vectors, carrying the bacteria from one host to another.
Question 6: What is the medical term for the situation where a bowel loop herniates into Douglas's cul-de-sac?
- epistaxis
- enterocele (Correct answer)
- meningioma
- insulin
Correct answer: enterocele
An enterocele is a type of pelvic organ prolapse where a loop of the small intestine herniates into Douglas's cul-de-sac, which is the deepest part of the peritoneal cavity between the rectum and the uterus (or vagina). This causes the small bowel to push into the posterior vaginal wall. It is a common condition, particularly in women who have had multiple vaginal births or hysterectomies.
Question 7: What effects do antagonistic medications have?
- acromioclavicular joint to iliac crest
- repositioning penetrating towel clip
- upper arms, neckline and axillary region
- counteract the action of another drug (Correct answer)
Correct answer: counteract the action of another drug
Antagonistic medications are drugs that bind to a receptor site but do not activate it, thereby blocking or counteracting the action of another drug or natural substance (an agonist) that would normally activate that receptor. Their primary effect is to oppose or neutralize the physiological or pharmacological effects of another agent. This mechanism is often used to reverse drug overdoses or manage conditions caused by excessive receptor stimulation.
Question 8: What type of surgery is used to treat a condition where the urethral meatus is located on the upper surface of the penis?
- spinal stenosis
- epispadias repair (Correct answer)
- reverse trendelenburg
- incident report
Correct answer: epispadias repair
Epispadias is a congenital condition where the urethra does not form a complete tube, and the urethral opening (meatus) is located on the dorsal (upper) surface of the penis instead of at the tip. Epispadias repair is a surgical procedure designed to reconstruct the urethra and penis, repositioning the meatus to its correct anatomical location. This surgery aims to improve urinary function and cosmetic appearance.
Question 9: What is the name for the bacterial motion-producing threadlike appendages?
- insulin
- flagella (Correct answer)
- mitochondria
- fistula
Correct answer: flagella
Flagella are long, whip-like, threadlike appendages found on the surface of many bacteria and some eukaryotic cells. These structures are primarily responsible for cell motility, allowing bacteria to propel themselves through liquid environments. They rotate or undulate to create a swimming motion, enabling the bacteria to move towards nutrients or away from harmful substances.
Question 10: What is the Kraske position's other name?
- choroid
- trauma
- sprilli
- jackknife (Correct answer)
Correct answer: jackknife
The Kraske position is a surgical patient position commonly used for procedures involving the rectum and anus. In this position, the patient lies prone with the hips flexed and the knees bent, often with the operating table broken in the middle to elevate the hips. This position is also widely known as the jackknife position due to the patient's folded appearance, which provides excellent exposure to the perineal area.
Question 11: Where can you find a Baker's cyst?
- webbed fingers
- surgically clean
- 10 minutes
- popliteal fossa (Correct answer)
Correct answer: popliteal fossa
A Baker's cyst, also medically known as a popliteal cyst, is a fluid-filled sac that forms behind the knee. It typically arises from an accumulation of synovial fluid that has been pushed out of the knee joint due to underlying knee problems like arthritis or cartilage tears. The popliteal fossa is the anatomical space located at the back of the knee, which is the characteristic location for this type of cyst.
