36
Q

The mother of a 4 mo reports episodes of vomiting and diarrhea beginning 2 days ago. He has also had several episodes of screaming and drawing up his legs. Prior to this he has been healthy with normal weight gain. The least likely diagnosis is:

a) incarcerated hernia
b) gastroenteritis
c) intussusception
d) pyloric stenosis

A

d) pyloric stenosis

Pyloric stenosis occurs during the first few weeks of life with projectile vomiting and weight loss

37
Q

The mother of a 4 mo reports episodes of vomiting and diarrhea beginning 2 days ago. He has also had several episodes of screaming and drawing up his legs. Prior to this he has been healthy with normal weight gain. PE reveals a sausage-shaped mass and guaiac-positive stool. This would confirm a diagnosis of:

a) incarcerated hernia
b) gastroenteritis
c) intussusception
d) pyloric stenosis

A

c) intussusception

Invagination of the bowel can result in a sausagelike mass being palpated in the upper right quadrant of the abdomen with occasional bloody stools.

38
Q

A 14 yo presents with abdominal pain that has occurred several times over the past 3 months. The pain is described as intermittent, sharp, and occasionally relieved with a heating pad. PE is normal. You suspect recurrent abdominal pain (RAP). Which clinical finding is most consistent with RAP?

a) periumbilical pain
b) constipation
c) pain worsens with defecation
d) weight loss

A

a) periumbilical pain

Recurrent abdominal pain is almost always nonorganic in origin. Other than complaints of pain, usually periumbilical or midepigastric, the history and physical are normal.

39
Q

Education and counseling of the parents of a 4 mo child with GER should include all of the following except?

a) thicken formula with rice cereal
b) change to a hypoallergenic formula
c) place infant in a car seat after feeding
d) avoid exposure of the infant to tobacco smoke

A

c) place infant in a car seat after feeding

Sitting the infant in a car seat or other similar device compresses the stomach, making the infant more likely to reflux. A 2 week trial of a hypoallergenic formula is suggested as reflux may be due to milk protein allergy. Secondhand smoke exacerbates reflux. Thickening the formula with rice cereal reduces regurgitation and improves quality of life for the caregivers.

40
Q

A 6 yo complains of sharp epigastric pain radiating to his back. Which lab data would be consistent with these physical signs?

a) decreased serum albumin
b) elevated serum amylase
c) elevated serum gastrin
d) decreased serum protein

A

b) elevated serum amylase

The physical signs described are characteristic of pancreatitis, which can be confirmed with serum amylase. Decreased serum albumin and protein are associated with Crohn’s disease. The clinical picture of Crohn’s usually includes cramping and does not radiate to the back.

41
Q

An umbilical hernia:

a) occurs more frequently in full term infants
b) resolves spontaneously in 3 to 6 months
c) is frequently associated with diastasis recti
d) responds well to taping

A

c) is frequently associated with diastasis recti

Umbilical hernias are a result of incomplete closure of the fascia of the umbilical ring. If small they may close in 1 year. The incidence is higher in low birth weight and premature infants. There is no evidence that manual reduction such as taping hastens closure.

42
Q

A 9 yo is brought into the clinic with abdominal pain that wakes her at night. Her parents have recently divorced and she is attending a new school. She has missed 8 days of school in the past 6 weeks. She reports occasional emesis. An appropriate management plan would be:

a) a bland diet with small frequent feedings
b) a referral to a gastroenterologist
c) to stress the importance of school attendance
d) to consult with the school psychologist

A

b) a referral to a gastroenterologist

Initially because of the social history, one might think that this recurrent abdominal pain is part of school refusal syndrome. However, the night waking and occasional emesis suggests peptic ulcer disease. Changes in diet are not usually effective in treating peptic ulcers. This warrants immediate referral to gastro.

43
Q

A 7 mo is seen with a 2 day history of diarrhea. He has had 3-4 wet diapers in the past 24 hours. The anterior fontanel is slightly depressed. Capillary refill is normal. Which degree of dehydration is most consistent with these findings?

a) 1-2%
b) 3-5%
c) 6-10%
d) greater than 10%

A

c) 6-10%

A depressed fontanel and decreased urine output are indicative of moderate dehydration.

44
Q

A 7 mo is seen with a 2 day history of diarrhea. He has had 3-4 wet diapers in the past 24 hours. The anterior fontanel is slightly depressed. Capillary refill is normal. Based on your assessment the appropriate management plan for his dehydration would be to:

a) begin BRAT diet
b) withhold formula for 24 hours and give electrolyte solution
c) begin rehydration in the office and observe for 3-4 hours
d) refer immediately for parenteral fluids

A

c) begin rehydration in the office and observe for 3-4 hours

The appropriate treatment for moderate dehydration is oral rehydration begun at the healthcare setting and observation until rehydration is complete.

45
Q

A 3 do presents with vomiting, abdominal distension, and constipation. Which of the following should you include in the differential?

a) hirschsprung disease
b) pyloric stenosis
c) celiac disease
d) meckel diverticulum

A

a) hirschsprung disease

Hirschsprung should be suspected in any newborn with abdominal distention and difficulty passing stool. Age and clinical findings are helpful in establishing this diagnosis. Celiac presents with diarrhea. Pyloric stenosis is not associated with abdominal distention, and Meckel diverticulum presents in the toddler period as painless rectal bleeding.

46
Q

A 4 yo was diagnosed with celiac at age 18 months. In addition to closely monitoring her growth, you also monitor for anemia. At this visit her lab results confirm an elevated MCV. An appropriate follow-up lab test would be serum:

a) protein
b) ferritin
c) folate
d) transferrin

A

c) folate

Celiac disease is frequently associated with folic acid deficiency. An elevated MCV indicates macrocytosis. Anemia due to folate deficiency is macrocytic.

47
Q

An 11 yo presents with complaints of chronic diarrhea and abdominal pain. You note a 5 kg weight loss from last year’s annual exam. Today his examination reveals RLQ pain and perianal skin tags. The most likely diagnosis is:

a) encopresis
b) crohn’s disease
c) irritable bowel disease
d) ulcerative colitis

A

b) crohn’s disease

While abdominal pain and diarrhea are common to all the choices, the RLQ pain is more suggestive of chohn’s disease. Perianal skin tags are common in crohn’s but would be unlikely in the others.

48
Q

A 9 yo presents with diffuse abdominal pain and acute onset of diarrhea described as frequent urge to deficate. She is passing large amounts of stool, and complains of tenderness during rectal exams. The clinical picture is highly suggestive of:

a) gastroenteritis
b) ulcerative colitis
c) giardiasis
d) appendicitis

A

d) appendicitis

Large amounts of gas and watery stools occur about 15% of the time in appendicitis, and pain upon rectal examination is a classic symptom.

49
Q

A 9 yo presents with diffuse abdominal pain and acute onset of diarrhea described as frequent urge to deficate. She is passing large amounts of stool, and complains of tenderness during rectal exams. Which of the following laboratory tests would confirm your diagnosis?

a) serum albumin
b) abdominal ultrasound
c) stool for ova and parasites
d) bone age

A

b) abdominal ultrasound

Abdominal US can reveal an enlarged appendix and help to eliminate ovarian and pelvic disease. Serum albumen and ESR would be helpful in diagnosing UC. Stool for O&P would be diagnostic of giardiasis.

50
Q

An 8 yo presents with his third episode of diarrhea in 3 months. He also complains of frequent flatulence and a decreased appetite. After going over the history, you recall that he went on a camping trip several months ago. What is his most likely diagnosis?

a) celiac disease
b) giardiasis
c) rotovirus
d) crohn’s disease

A

b) giardiasis

Giardiasis is the most common intestinal protozoal infection in children in the US. Infection is acquired through fecal-oral route and is associated with contaminated drinking water, especially in rural areas. It causes chronic, intermittent diarrhea, flatulence, poor appetite, and weight loss. there is no fever or blood in the stool.

51
Q

A 7 yo presents with a 1 week history of fever, nausea, and anorexia. His mother reports that his skin “looks funny” as well. further lab studies confirm a diagnosis of viral hepatitis. Which type of hepatitis is most likely?

a) Hep A
b) Hep B
c) Hep C
d) Hep D

A

a) Hep A

The acute onset and presence of fever as well as jaundice is associated with Hep A. Fevers are less common with other viral hepatitis conditions.

52
Q

A 2 wo is being seen for the first time since discharge from the hospital. She currently weighs 3.6 kg which is 0.3 kg below her birth weight. You learn that the mother has been using too little water when preparing formula. Which of the symptoms is least likely related to this error?

a) vomiting
b) diarrhea
c) dehydration
d) flatus

A

d) flatus

Vomiting in the newborn period may be caused by improper preparation of formula. Too little water will increase the GI and renal solute load, which may result in vomiting, diarrhea, and dehydration. Flatus is usually a result of swallowing too much air.

53
Q

Vomitus that is billous suggests:

a) GI obstruction proximal to the pylorus
b) GI obstruction below the ampulla of Vater
c) Pyloric stenosis
d) peptic ulcer disease

A

b) GI obstruction below the ampulla of Vater

Vomiting bile is generally considered a serious sign that usually indicates an obstruction below the ampulla of Vater.

54
Q

A 5 yo presents with a history of stool staining his underwear, evidence of bright red blood after wiping, and abdominal discomfort. the physical exam reveals moderate abdominal distension with a midline abdominal mass. Rectal exam is positive for an impacted rectum and two small anal fissures. The priority of management would be:

a) increasing water and fiber in the diet, and limiting milk intake
b) regular toilet sitting for 10 minutes, 3 times per day
c) two fleet enemas
d) mineral oil after breakfast and before bed

A

c) two fleet enemas

The clinical picture is consistent with encopresis. The abdomen can be distended and often a mass palpated. Anal fissures may be present from straining, but skin tags are unlikely. The first step in treatment is to remove the impaction. Once the colon is cleared, maintenance with stool softeners, diet, and regular toileting is appropriate.

55
Q

Which of the following would not be included in the management of pinworms?

a) nutritional support and iron supplementation
b) simultaneous treatment of all family members
c) washing bed linen in hot water
d) keeping fingernails short and clean

A

a) nutritional support and iron supplementation

Pinworms are a common parasite infecting children. They are easily treated with medication and simple environmental measures. No nutritional deficiencies are associated with pinworms.

56
Q

A 6 mo has been started on rice cereal sweetened with 1 TBS of honey. In addition, the infant is consuming 42oz of formula. His height and weight are at 50% on the growth curve. You would recommend:

a) adding pureed vegetables
b) substituting 4 oz juice for a formula feeding
c) adding scrambled egg whites
d) discontinuing honey

A

d) discontinuing honey

Honey may contain clostridium botulinum spores and should not be given to infants less than 1 year old. Adding vegetables is appropriate, but the risk of infant botulism is potentially life threatening. Although juice may be added, it should not be substituted for formula. Egg whites may be added at the end of the first year.

57
Q

Appropriate feeding volumes for newborn to 5 mo:

A
