Question 1

A 52-year-old secretary comes to your office, complaining about accidentally leaking urine when she coughs or sneezes. She says this has been going on for about a year now. She relates that she has not had a period for 2 years. She denies any recent illness or injuries. Her past medical history is significant for four spontaneous vaginal deliveries. She is married and has four children. She denies alcohol, tobacco, or drug use. During her pelvic examination you note some atrophic vaginal tissue, but the remainder of her pelvic, abdominal, and rectal examinations are unremarkable. Which type of urinary incontinence does she have?

Accepted Answer

Stress incontinence usually occurs when the intra-abdominal pressure goes up during coughing, sneezing, or laughing. This is usually due to a weakness of the pelvic floor, with inadequate muscle support of the bladder. Vaginal deliveries and pelvic surgery are often associated with these symptoms. Usually, female patients are postmenopausal when stress incontinence begins. Kegel exercises are usually recommended to strengthen the pelvic floor muscles.

Question 2

A 46-year-old former salesman presents to the ER, complaining of black stools for the past few weeks. His past medical history is significant for cirrhosis. He has gained weight recently, especially around his abdomen. He has smoked two packs of cigarettes a day for 30 years and has drunk approximately 10 alcoholic beverages a day for 25 years. He has used IV heroin and smoked crack in the past. He denies any recent use. He is currently unemployed and has never been married. On examination you find a man appearing older than his stated age. His skin has a yellowish tint and he is thin, with a prominent abdomen. You note multiple "spider angiomas" at the base of his neck. Otherwise, his heart and lung examinations are normal. On inspection he has dilated veins around his umbilicus. Increased bowel sounds are heard during auscultation. Palpation reveals diffuse tenderness that is more severe in the epigastric area. His liver is small and hard to palpation and he has a positive fluid wave. He is positive for occult blood on his rectal examination. What cause of black stools most likely describes his symptoms and signs?

Accepted Answer

Varices are often found in alcoholic patients, but only when they have a diagnosis of significant cirrhosis. This patient has symptoms of cirrhosis, including jaundice, ascites, spider hemangiomas, and dilated veins on his abdomen (caput medusa).

Question 3

A 21-year-old receptionist comes to your clinic, complaining of frequent diarrhea. She states that the stools are very loose and there is some cramping beforehand. She states this has occurred on and off since she was in high school. She denies any nausea, vomiting, or blood in her stool. Occasionally she has periods of constipation, but that is rare. She thinks the diarrhea is much worse when she is nervous. Her past medical history is not significant. She is single and a junior in college majoring in accounting. She smokes when she drinks alcohol but denies using any illegal drugs. Both of her parents are healthy. Her entire physical examination is unremarkable. What is most likely the etiology of her diarrhea?

Accepted Answer

Irritable bowel syndrome will cause loose bowel movements with cramps but no systemic symptoms of fever, weight loss, or malaise. This syndrome is more likely in young women with alternating symptoms of loose stools and constipation. Stress usually makes the symptoms worse, as do certain foods.

Question 4

A 42-year-old florist comes to your office, complaining of chronic constipation for the last 6 months. She has had no nausea, vomiting, or diarrhea and no abdominal pain or cramping. She denies any recent illnesses or injuries. She denies any changes to her diet or exercise program. She is on no new medications. During the review of systems you note that she has felt fatigued, had some weight gain, has irregular periods, and has cold intolerance. Her past medical history is significant for one vaginal delivery and two cesarean sections. She is married, has three children, and owns a flower shop. She denies tobacco, alcohol, or drug use. Her mother has type 2 diabetes and her father has coronary artery disease. There is no family history of cancers. On examination she appears her stated age. Her vital signs are normal. Her head, eyes, ears, nose, throat, and neck examinations are normal. Her cardiac, lung, and abdominal examinations are also unremarkable. Her rectal occult blood test is negative. Her deep tendon reflexes are delayed in response to a blow with the hammer, especially the Achilles tendons. What is the best choice for the cause of her constipation?

Accepted Answer

Many metabolic conditions can interfere with bowel motility. In this case the patient has many symptoms of hypothyroidism, including cold intolerance, weight gain, fatigue, constipation, and irregular menstrual cycles. On examination, thyromegaly and delayed reflexes can help to make the diagnosis. Medication will usually correct these symptoms.

Question 5

A 22-year-old law student comes to your office, complaining of severe abdominal pain radiating to his back. He states it began last night after hours of heavy drinking. He has had abdominal pain and vomiting in the past after drinking but never as bad as this. He cannot keep any food or water down, and these symptoms have been going on for almost 12 hours. He has had no recent illnesses or injuries. His past medical history is unremarkable. He denies smoking or using illegal drugs but admits to drinking 6 to 10 beers per weekend night. He admits that last night he drank something like 14 drinks. On examination you find a young male appearing his stated age in some distress. He is leaning over on the examination table and holding his abdomen with his arms. His blood pressure is 90/60 and his pulse is 120. He is afebrile. His abdominal examination reveals normal bowel sounds, but he is very tender in the left upper quadrant and epigastric area. He has no Murphy's sign or tenderness in the right lower quadrant. The remainder of his abdominal examination is normal. His rectal, prostate, penile, and testicular examinations are normal. He has no inguinal hernias or tenderness with that examination. Blood work is pending. What etiology of abdominal pain is most likely causing his symptoms?

Accepted Answer

Acute pancreatitis causes epigastric and left upper quadrant pain and often radiates into the back. There is often a history of long-standing gallbladder disease or recent alcohol ingestion. Severe abdominal pain and vomiting are often seen. Medications such as proton pump inhibitors can also cause pancreatitis in people without these other risk factors. Treatment includes hydration, pain management, and bowel rest.

Question 6

A 76-year-old retired farmer comes to your office complaining of abdominal pain, constipation, and a low-grade fever for about 3 days. He denies any nausea, vomiting, or diarrhea. The only unusual thing he remembers eating is two bags of popcorn at the movies with his grandson, 3 days before his symptoms began. He denies any other recent illnesses. His past medical history is significant for coronary artery disease and high blood pressure. He has been married for over 50 years. He denies any tobacco, alcohol, or drug use. His mother died of colon cancer and his father had a stroke. On examination he appears his stated age and is in no acute distress. His temperature is 100.9 degrees and his other vital signs are unremarkable. His head, cardiac, and pulmonary examinations are normal. He has normal bowel sounds and is tender over the left lower quadrant. He has no rebound or guarding. His rectal examination is unremarkable and his fecal occult blood test is negative. His prostate is slightly enlarged but his testicular, penile, and inguinal examinations are all normal. Blood work is pending. What diagnosis for abdominal pain best describes his symptoms and signs?

Accepted Answer

Diverticulitis is caused by localized infections within the colonic diverticula. Constipation, fever, and abdominal pain are common. Mesenteric ischemia classically presents in older people with a history of vascular disease elsewhere. The typical pain is unusual in that it is not made worse by examination despite being severe. Some mistake this feature to indicate malingering, with bad results.

Question 7

A 77-year-old retired bus driver comes to your clinic for a physical examination at his wife's request. He has recently been losing weight and has felt very fatigued. He has had no chest pain, shortness of breath, nausea, vomiting, or fever. His past medical history includes colon cancer, for which he had surgery, and arthritis. He has been married for over 40 years. He denies any tobacco or drug use and has not drunk alcohol in over 40 years. His parents both died of cancer in their 60s. On examination his vital signs are normal. His head, cardiac, and pulmonary examinations are unremarkable. On abdominal examination you hear normal bowel sounds, but when you palpate his liver it is abnormal. His rectal examination is positive for occult blood. What further abnormality of the liver was likely found on examination?

Accepted Answer

With his past history of colon cancer and with recent weight loss and fatigue, a relapse of his colon cancer would be expected. Colon cancer usually metastasizes to the liver, creating hard, irregular nodules, which can sometimes be palpated on examination. A smooth, large liver which is tender is often seen in hepatitis.

Question 8

A 26-year-old sports store manager comes to your clinic, complaining of severe right-sided abdominal pain for 12 hours. He began having a stomachache yesterday, with a decreased appetite, but today the pain seems to be just on the lower right side. He has had some nausea and vomiting but no constipation or diarrhea. His last bowel movement was last night and was normal. He has had no fever or chills. He denies any recent illnesses or injuries. His past medical history is unremarkable. He is engaged. He denies any tobacco or drug use and drinks four to six beers per week. His mother has breast cancer and his father has coronary artery disease. On examination he appears ill and is lying on his right side. His temperature is 100.4 and his heart rate is 110. His bowel sounds are decreased and he has rebound and involuntary guarding, one third of the way between the anterior superior iliac spine and the umbilicus in the right lower quadrant. His rectal, inguinal, prostate, penile, and testicular examinations are normal. What is the most likely cause of his pain?

Accepted Answer

Appendicitis is common in the young and usually presents with periumbilical pain that localizes to the right lower quadrant in an area known as McBurney's Point, described above as one third of the way between the anterior superior iliac spine and the umbilicus on the right. Rebound and guarding are common. Remote rebound or Rovsing's sign is also seen commonly when the course of appendicitis is advanced. Bowel movements are usually unaffected.

Question 9

A 15-year-old high school freshman is brought to the clinic by his mother because of chronic diarrhea. The mother states that for the past couple of years her son has had diarrhea after many meals. The patient states that the diarrhea seems the absolute worst after his school lunches. He describes his symptoms as cramping abdominal pain and gas followed by diarrhea. His stools are watery with no specific smell. He denies any nausea, vomiting, constipation, weight loss, or fatigue. He has had no recent illness, injuries, or foreign travel. His past medical history is unremarkable. He denies tobacco, alcohol, or drug use. His parents are both healthy. On examination you see a relaxed young man breathing comfortably. His vital signs are normal and his head, eyes, ears, throat, neck, cardiac, and pulmonary examinations are normal. His abdomen is soft and nondistended. His bowel sounds are active, and he has no tenderness, no enlarged organs, and no rebound or guarding. His rectal examination is nontender with no blood on the glove. You collect a stool sample for further study. What is the most likely explanation for this patient's chronic diarrhea?

Accepted Answer

Usually related to lactose intolerance, watery diarrhea often follows meal ingestion. Crampy abdominal pain, distension, and gas often accompany symptoms. Diarrhea is often provoked by pizza, milkshakes, yogurt, and other lactose-containing foods. This condition is more common in African-Americans, Latinos, Native Americans, and Asians.

Question 10

A 27-year-old policewoman comes to your clinic, complaining of severe left-sided back pain radiating down into her groin. It began in the middle of the night and woke her up suddenly. It hurts in her bladder to urinate but she has no burning on the outside. She has had no frequency or urgency with urination but she has seen blood in her urine. She has had nausea with the pain but no vomiting or fever. She denies any other recent illness or injuries. Her past medical history is unremarkable. She denies tobacco or drug use and drinks alcohol rarely. Her mother has high blood pressure and her father is healthy. On examination she looks her stated age and is in obvious pain. She is lying on her left side trying to remain very still. Her cardiac, pulmonary, and abdominal examinations are unremarkable. She has tenderness just inferior to the left costovertebral angle. Her urine pregnancy test is negative and her urine analysis shows red blood cells. What type of urinary tract pain is she most likely to have?

Accepted Answer

The pain from a kidney stone causes dramatic, severe, colicky pain at the costovertebral angle that radiates across the flank and down into the groin.

Question 11

Chris is a 20-year-old college student who has had abdominal pain for 3 days. It started at his umbilicus and was associated with nausea and vomiting. He was unable to find a comfortable position. Yesterday, the pain became more severe and constant. Now, he hesitates to walk, because any motion makes the pain much worse. It is localized just medial and inferior to his iliac crest on the right. Which of the following is most likely?

Accepted Answer

This is a classic history for appendicitis. Notice that the pain has changed from visceral to parietal. It is well localized to the right lower quadrant, making appendicitis a strong consideration.

Question 12

Bill, a 55-year-old man, presents with pain in his epigastrium which lasts for 30 minutes or more at a time and has started recently. Which of the following should be considered?

Accepted Answer

Epigastric pain can have many causes. History and physical will help discern which causes are most likely, but it is important to realize that any of the above, including myocardial ischemia, is always a possibility. Pneumonia and gallbladder pain can also cause pain in this location.

Question 13

Monique is a 33-year-old administrative assistant who has had intermittent lower abdominal pain approximately one week a month for the past year. It is not related to her menses. She notes relief with defecation, and a change in form and frequency of her bowel movements with these episodes. Which of the following is most likely?

Accepted Answer

Although colon cancer should be a consideration, these symptoms are intermittent and no note is made of progression. Cholecystitis usually presents with right upper quadrant pain. Inflammatory bowel disease is often associated with fever and hematochezia. Because there is relief with defecation and there are no mentioned structural or biochemical abnormalities, irritable bowel syndrome seems most likely. This is a very common condition which can be triggered by certain foods and stress.

Question 14

Jim is a 60-year-old man who presents with vomiting. He denies seeing any blood with emesis, which has been occurring for 2 days. He does note a dark, granular substance resembling the coffee left in the filter after brewing. What do you suspect?

Accepted Answer

When blood is exposed to the environment of the stomach, it often resembles "coffee grounds." This is not always recognized by patients as blood, so it is important to inquire about this. This symptom is not common in cholecystitis, and the other possibilities occur lower in the intestine. It should be noted that conversely, rapid bleeding from the stomach or other upper gastrointestinal source can produce bright red blood in the stool. Do not rule out proximal bleeding on the basis of the absence of "coffee grounds." Likewise, bright red blood seen with emesis may originate from the stomach. Black, sticky stools also can accompany upper GI bleeding.

Question 15

A daycare worker presents to your office with jaundice. She denies IV drug use, blood transfusion, and travel and has not been sexually active for the past 10 months. Which type of hepatitis is most likely?

Accepted Answer

The lack of contact with blood and body fluids makes hepatitis B, C, and D unlikely. She regularly changes the diapers of her clients and is at risk for hepatitis A. Vaccine against hepatitis A is recommended for daycare workers.

Question 16

Linda is a 29-year-old who had excruciating pain which started under her lower ribs on the right side. The pain eventually moved to her lateral abdomen and then into her right lower quadrant. Which is most likely, given this presentation?

Accepted Answer

The presentation of right flank pain spiraling down to the groin is typical of a ureteral stone. There would most likely be microscopic hematuria as well. The migration pattern of this condition makes the others less likely.

Question 17

Mrs. LaFarge is a 60-year-old who presents with urinary incontinence. She is unable to get to the bathroom quickly enough when she senses the need to urinate. She has normal mobility. Which of the following is most likely?

Accepted Answer

Stress incontinence occurs with increased intra-abdominal pressure such as with coughing, sneezing, or laughing. This history is most consistent with urge incontinence secondary to detrusor overactivity. Overflow incontinence occurs with anatomic obstruction such as prostatic hypertrophy (obviously not in this case, as the patient is a woman), urethral stricture, or neurogenic bladder. Functional incontinence results from lack of mobility severe enough to impair getting to the bathroom quickly enough.

Question 18

A 62-year-old woman has been followed by you for 3 years and has had recent onset of hypertension. She is still not at goal despite three antihypertensive medicines, and you strongly doubt nonadherence. Her father died of a heart attack at age 58. Today her pressure is 168/94 and pressure on the other arm is similar. What would you do next?

Accepted Answer

At this point, it is important to consider secondary causes for this woman's hypertension because of its severity, rapidity of progression, and lack of response to therapy. While you will most likely add a fourth medicine, it is important to carefully examine the abdomen for the presence of renal artery bruits. These are usually heard best in the upper quadrants. It may be necessary to have the patient hold her breath, to have a very quiet room, and to listen with the diaphragm for a very soft, high-pitched sound with systole. It may also help to simultaneously feel the patient's pulse (a bruit with both a systolic and diastolic component is very specific for a significant blockage, while a lone systolic bruit may not be abnormal). Obtaining a CT scan is not likely to be useful, and you may save the delay, expense, and inconvenience of a nephrology referral if you can hear a bruit.

Question 19

Mr. Patel is a 64-year-old man who was told by another care provider that his liver is enlarged. Although he is a life-long smoker, he has never used drugs or alcohol and has no knowledge of liver disease. Indeed, on examination, a liver edge is palpable 4 centimeters below the costal arch. Which of the following would you do next?

Accepted Answer

A liver edge palpable this far below the costal arch should not be ignored. Ultrasound and laboratory investigation are reasonable if the liver is actually enlarged. Mr. Patel has developed emphysema with flattening of the diaphragms. This pushes a normal-sized liver below the costal arch so that it appears to be enlarged. A liver span should be determined by percussing down the chest wall until dullness is heard. A measurement is then made between this point and the lower border of the liver to determine its span; 6-12 centimeters in the mid-clavicular line is normal. Percussion is the only way to assess liver size on examination, and in this case it saved the patient much inconvenience and expense.

Question 20

Cody is a teenager with a history of leukemia and an enlarged spleen. Today he presents with fairly significant left upper quadrant pain. On examination of this area a rough grating noise is heard. What is this sound?

Accepted Answer

A rough, grating noise over this area represents a splenic rub, which can accompany splenic infarction. Rubs also occur over the liver and pleura and pericardium.
