Question 1

A 2-year-old child has an acute diarrheal illness. The child is afebrile and, with oral rehydration measures, has remained well hydrated. The parent asks what can be done to help shorten the course of this illness. What will the primary care pediatric nurse practitioner recommend?

A) Clear liquids only
B) Lactobacillus
C) Loperamide
D) Peppermint oil

B

Accepted Answer

The primary care pediatric nurse practitioner may recommend the use of lactobacillus to help shorten the course of the illness. Lactobacillus may help to restore the balance of gut bacteria and reduce the severity of symptoms. However, it is important to note that the use of other medications such as loperamide or peppermint oil is not recommended for a 2-year-old child with acute diarrheal illness. Clear liquids and oral rehydration measures should be continued to maintain hydration.

Question 2

A 12-month-old infant exhibits poor weight gain after previously normal growth patterns. There is no history of vomiting, diarrhea, or irregular bowel movements, and the physical exam is normal. What is the next step in evaluating these findings?

A) Complete blood count and electrolytes
B) Feeding and stooling history and 3-day diet history
C) Stool cultures for ova and parasites
D) Swallow study with videofluoroscopy

B

Accepted Answer

The next step should be to assess the infant's feeding and stooling history as well as a 3-day diet history to evaluate potential nutritional issues. This information can help identify possible underlying causes of poor weight gain, such as inadequate nutrient intake or feeding difficulties. Further diagnostic testing, such as a swallow study or stool cultures, may be warranted depending on the results of this initial evaluation.

Question 3

A toddler is seen in the clinic after a 2-day history of intermittent vomiting and diarrhea. An assessment reveals an irritable child with dry mucous membranes, 3-second capillary refill, 2- second recoil of skin, mild tachycardia and tachypnea, and cool hands and feet. The child has had two wet diapers in the past 24 hours. What will the primary care pediatric nurse practitioner recommend?

A) Anti-diarrheal medication and clear fluids for 24 hours
B) Bolus of IV normal saline in the clinic until improvement
C) Hospital admission for IV rehydration and oral fluids
D) Oral rehydration solution with follow-up in 24 hours

D

Accepted Answer

The child's symptoms suggest dehydration and thus, the primary care pediatric nurse practitioner should recommend ORS (oral rehydration solution) with follow-up in 24 hours. Hospitalization may be considered for children with severe dehydration or those unable to tolerate ORS. Anti-diarrheal medication is contraindicated in children with diarrhea and should be avoided. Bolus of IV normal saline may be considered in children with severe dehydration but not in mild to moderate dehydration.

Question 4

A 9-year-old girl has a history of frequent vomiting and her mother has frequent migraine headaches. The child has recently begun having more frequent and prolonged episodes accompanied by headaches. An exam reveals abnormal eye movements and mild ataxia. What is the correct action?

A) Begin using an anti-migraine medication to prevent headaches.
B) Prescribe ondansetron and lorazepam to help manage symptoms.
C) Reassure the parent that this is expected with cyclic vomiting syndrome.
D) Refer to a pediatric gastroenterologist for further workup.

Accepted Answer

The frequent vomiting, headaches, abnormal eye movements, and ataxia suggest that there may be an underlying neurological or gastrointestinal condition present. It is important to refer the child to a specialist who can perform a thorough workup and provide appropriate management.

Question 5

An 18-month-old child has a 1-day history of intermittent, cramping abdominal pain with non-bilious vomiting. The child is observed to scream and draw up his legs during pain episodes and becomes lethargic in between. The primary care pediatric nurse practitioner notes a small amount of bloody, mucous stool in the diaper. What is the most likely diagnosis?

A) Appendicitis
B) Gastroenteritis
C) Intussusception
D) Testicular torsion

Accepted Answer

The intermittent, cramping abdominal pain with vomiting, along with lethargy and drawing up of legs suggest abdominal pain. The presence of bloody, mucous stool suggests lower gastrointestinal bleeding. These symptoms, along with the age of the child, are highly suggestive of intussusception, which is a condition where a portion of the intestine telescopes or invaginates into another part, causing blockage and eventually decreasing blood flow, leading to ischemia and necrosis. Appendicitis typically presents with continuous abdominal pain, fever, and with a focus on the right lower quadrant of the abdomen. Gastroenteritis usually causes diarrhea, vomiting, and abdominal pain, but typically does not have bloody stool. Testicular torsion is a condition affecting the male genitalia and is not relevant for this child's symptoms.

Question 6

A 10-year-old child has had abdominal pain for 2 days, which began in the periumbilical area and then localized to the right lower quadrant. The child vomited once today and then experienced relief from pain followed by an increased fever. What is the likely diagnosis?

A) Appendicitis with perforation
B) Gastroenteritis
C) Pelvic inflammatory disease (PID)
D) Urinary tract infection (UTI)

Accepted Answer

The onset of abdominal pain in the periumbilical area and then localizing to the right lower quadrant, along with vomiting and increased fever, are classical symptoms of appendicitis. The relief from pain after vomiting can also indicate perforation, which is a serious complication of appendicitis. Gastroenteritis, PID, and UTI typically present with different symptoms and would not explain this child's symptoms.

Question 7

A school-age child has a 3-month history of dull, aching epigastric pain that worsens with eating and awakens the child from sleep. A complete blood count shows a hemoglobin of 8 mg/dL. What is the next step in management?

A) Administration of HRA or PPI medications
B) Empiric therapy for H. pylori (HP)
C) Ordering an upper GI series
D) Referral for esophagogastroduodenoscopy (EGD)

Accepted Answer

The history and symptoms of epigastric pain worsened by eating and awakening the child from sleep, combined with a low hemoglobin, suggest a possible peptic ulcer or upper gastrointestinal bleeding. An EGD is the most appropriate next step in management to visualize the upper GI mucosa and potentially obtain biopsies for H. pylori testing or ruling out other underlying conditions. Administration of HRA or PPI medications and empiric therapy for H. pylori may be considered but should not be initiated without confirming the diagnosis through endoscopy. An upper GI series may also be considered, but EGD has better diagnostic yield and is preferred in cases of suspected peptic ulcer disease.

Question 8

An adolescent is diagnosed with functional abdominal pain (FAP). The child's symptoms worsen during stressful events, especially with school anxiety. What will be an important part of treatment for this child?

A) Informing the parents that the pain is most likely not real
B) Instituting a lactose-free diet along with lactobacillus supplements
C) Teaching about the brain-gut interaction causing symptoms
D) Using histamine2-blockers to help alleviate symptoms

Accepted Answer

Teaching the child about the brain-gut interaction causing symptoms is important in the treatment of FAP. It helps the child understand that the pain is real, but is caused by stress and emotions rather than a physical problem. This knowledge can empower the child and help reduce anxiety around the pain. Lactose-free diet and lactobacillus supplements may be helpful in some cases of FAP, but are not always necessary. Histamine2-blockers are not indicated in the treatment of FAP. Informing the parents that the pain is not real is inappropriate and unhelpful.

Question 9

The parent of an infant experiencing colic asks about using a probiotic medication. What will the primary care pediatric nurse practitioner tell this parent?&#10;A) Probiotic medications have demonstrated efficacy in treating colic.&#10;B) Probiotics are not safe to use to treat infants who have colic.&#10;C) There are no studies showing usefulness of probiotics to manage colic.&#10;D) There is no conclusive evidence about using probiotics to treat colic.

Accepted Answer

Although there has been some studies on the use of probiotics to treat colic, the evidence is not conclusive. Therefore, the best answer is D. It is important for healthcare providers to provide accurate information to parents about the safety and effectiveness of treatments for their infants.

Question 10

A toddler who was born prematurely refuses most solid foods and has poor weight gain. A barium swallow study reveals a normal esophagus. What will the primary care pediatric nurse practitioner consider next to manage this child's nutritional needs?

A) Consultation with a dietician
B) Fiberoptic endoscopy evaluation
C) Magnetic resonance imaging
D) Videofluoroscopy swallowing study

Accepted Answer

A videofluoroscopy swallowing study is used to assess swallowing function and identify any aspiration or swallowing difficulties, which is important for managing feeding issues in a child with poor weight gain.

Question 11

A child is diagnosed with Crohn disease. What are likely complications for this child?&#10;A) Cancer of the colon and possible colectomy&#10;B) Intestinal obstruction with scarring and strictures&#10;C) Intestinal perforation and hemorrhage&#10;D) Liver disease and sepsis
