APEA 3P Exam Prep- GI Questions with
Correct Answers and Explanations
The relationship between colon polyps and colon cancer is those polyps:
eventually, all become malignant.
have a slow progression to colon cancer.
have a rapid progression to colon cancer.
have no relationship to colon cancer.
B.
Colon polyps are usually slow-growing and take a long time to progress to cancer. This is the reason that a
colonoscopy does not need to be repeated annually. While not all polyps grow slowly, this is the usual
progression.
A 5-year-old has been diagnosed with pinworms. He lives with his mother. There are no other members of
the household. How should his mother be managed?
Reassure the mother that if she develops symptoms, she will need to be treated.
Visually assess the mother’s rectum for redness or presence of worms.
Have the mother collect a stool specimen and send it to the laboratory.
Perform the “scotch tape” test and look at the collection under the microscope.
D.
The diagnosis of pinworms (Enterobiasis) is made by using a piece of scotch tape on a tongue depressor. It is
touched against the patient’s rectum. The greatest yield of eggs will occur during the nighttime or early AM.
Eggs will be found here if they are present. Worms and eggs are rarely found in stool specimens, so this is
not a good plan. When the scotch tape is examined under a low power microscope, the eggs will be easily
visualized since they are large and bean shaped. The finding of an adult worm would confirm the diagnosis.
These are large enough to be seen with the naked eye. If the mother is symptomatic, she should be treated
with or without a rectal exam. It is very likely she is infected.
A patient has been diagnosed with hepatitis B. The most commonly reported risk factor is:
drinking contaminated water.
,eating contaminated food.
exposure to blood.
sexual exposure.
D.
Hepatitis B is transmitted by blood and body fluids. While exposure to infected blood or blood products would
significantly increase the risk of infection in unvaccinated people, this is much less likely than becoming
infected via sexual exposure or IV drug use. Hepatitis A is transmitted via fecal-oral routes. Drinking
contaminated water and eating contaminated food implicate hepatitis A as the etiologic agent.
The three most common causes of bacterial diarrhea in the US are Salmonella, Campylobacter, and:
E. coli.
Enterovirus.
Yersinia.
Shigella.
D.
Shigella will be shed continuously in the stool and should be easily identified on stool culture. When bacterial
gastroenteritis is suspected, a stool specimen could be ordered for confirmation. Generally, these three
pathogens are easily identified if they are present. Enterovirus produces a viral form of diarrhea. Yersinia
produces the deadly disease called bubonic plague. E. coli is a typical colonic pathogen.
An 83-year-old patient is diagnosed with diverticulitis. The most common complaint is:
rectal bleeding.
bloating and cramping.
left lower quadrant pain.
frequent belching and flatulence.
C.
Diverticular disease is more common in older adults. About 70% of patients diagnosed with diverticulitis have
left lower quadrant pain. Rectal bleeding may have varied etiologies, such as rectal carcinoma or
hemorrhoids. Bloating and cramping are often found in patients with diverticular disease (diverticulosis) but
not specifically diverticulitis. Belching and flatulence are not specifically associated with diverticulosis.
What is true regarding older adults who are overweight?
,This is clearly associated with increased mortality in older adults.
Mortality in older adults related to overweight states declines over time.
BMI is a good way to assess nutritional status in older adults.
There are no potential metabolic or functional benefits to weight loss in older adults.
B.
Overweight and obese states are not as important in predicting mortality in older adults as they are in their
younger counterparts. After age 65 years (some studies demonstrate after age 70), weight is less significant
in decreasing risk for mortality than in younger adults. There are some benefits to weight loss in the obese
older adults. One of them is better balance and decreased risk for falls. Others include less sleep apnea,
decreased risk of diabetes, and decreased rates of shortness of breath with respiratory and cardiac diseases.
What medication used to treat patients who have GERD provides the fastest relief of heartburn symptoms?
Calcium carbonate
Ranitidine
Amantadine
Pantoprazole
A.
Calcium carbonate is an antacid. It provides rapid changes in gastric pH. This provides relief that can be
noticed immediately. The increase in pH lasts for about 30 minutes and corresponds with resolution of
symptoms. However, as pH decreases within 30 minutes, symptoms may return. Ranitidine is an H2 blocker.
It provides relief in 1-2 hours. This usually lasts for about 6-12 hours. Amantadine is an antiviral not used to
treat GERD. Pantoprazole is a proton pump inhibitor. This provides relief after several hours or days of daily
consumption.
An 84-year-old presents with a stated involuntary weight loss. He states that he’s lost about 6 pounds in the
last 6 or 8 weeks. What statement below is NOT part of the assessment?
The weight loss should be measured today and again in the next few weeks.
A laboratory evaluation should be performed.
Evaluate his dietary intake.
Evaluate his upper and lower extremity muscle mass.
D.
, Involuntary weight loss in older adults is often due to malignancy or disease. The initial assessment of an
older adult who reports involuntary weight loss is to document the weight loss. If prior measurements are
part of the patient’s chart, this would be helpful. Laboratory assessment should also be performed.
Consideration should be given to performing a CBC, TSH, and metabolic panel. Also consider chest and
abdominal X-rays. If all are normal, he should be monitored and reweighed on the same scale for
comparison. A dietary consult should be ordered. However, even with negative initial findings, a significant
number of patients are later found to have disease or malignancy
A patient has a positive hepatitis B surface antibody. This means he:
has acute hepatitis B.
has chronic hepatitis B.
is immune to hepatitis B.
needs immunization to hepatitis B.
C.
The hepatitis B surface antibody indicates immunity to hepatitis B virus. Specifically, if this patient comes in
contact with hepatitis B virus, he will not become infected with hepatitis B. The presence of hepatitis B
surface antibody indicates immunity from immunization or actual infection. It also indicates recovery if the
patient was infected.
A patient with a suspected inguinal hernia should be examined:
in the prone position.
standing.
side-lying.
with patient squatting.
B.
The patient should be examined while he is standing. He should be asked to bear down, cough, or strain
during the exam. Though hernias are far more common in males, they can be found in females too. In males,
the patient should be asked to stand. The examiner should put his 2nd or 3rd finger through the scrotum and
into the external ring. When the patient is asked to cough, a “silky” feel will butt up against the examiner’s
finger, and the hernia can be easily felt.
A 15-year-old is about 10% below her ideal body weight. Laboratory studies were performed. Which
complaint might be common in this patient (Labs in image)?
Headaches
