A female athlete experiences anaphylaxis during a soccer game. The only significant history is
that she had lunch about 1 hour before the incident. Food-dependent exercise-induced
anaphylaxis is diagnosed. Of the following, the MOST likely cause is:
chocolate milkshake
pineapple
tomatoes
whole wheat bread
whole wheat bread
Exercise is a known co-factor in some children who experience anaphylaxis. Food-dependent
exercise-induced anaphylaxis (FDEIA) is defined as a food induced allergic reaction that occurs
during or soon after exercise. Children should not exercise within 2-3 hours of ingesting the
triggering food. Nuts, wheat, apples, bananas, kiwi, peaches and eggs frequently are the cause for
anaphylaxis.

Utilizing the Early Language Milestone Scale, beginning at the age of 11 months and continuing
to 24 months of age, the child should have a vocabulary of 50 words. This child should be able to
put words together in short, 2 - 3 word sentences and name at least one object in a picture. The
child at age 3 - 4 years will be able to tell a short story and begin to count. A 2 year old may
know his first name, but usually cannot state full name until he/she is older.

Motor vehicle accidents are the leading cause of death among children in the United States, with
78% of all unintentional injury deaths related to MVA among adolescents. When correctly used,
restraint systems can prevent fatalities and reduce the number and severity of injuries to children
and adolescents. As adolescents begin to drive and carry peer passengers, it is especially
important to remind them of basic safety issues, including the use of seat belts, emphasizing the
danger of driving, drinking and drug use as well as appropriate behavior while in the car.

decreased over recent years, especially among older children, and there is no link between
violent video games and increased accidents.
The parent of an 8 month old, reports switching the baby's formula to cow's milk due to the
continued expense of formula. Which is the BEST response?
Cow's milk does not contain adequate nutrition, and poses a higher risk for allergy.
Cow's milk has a lower protein and fat content, which will impede growth of the baby.
Switching to cow's milk sooner than 1 year will not cause any harm.
There is no need to continue formula as long as the child is receiving other baby foods.
Cow's milk does not contain adequate nutrition, and poses a higher risk for allergy.
During the first year of life, infants should receive only formula or breast milk. The use of cow's
milk is contraindicated because of its high protein content, inappropriate nutrition composition,
especially lack of iron sources, and the risk of gastrointestinal bleeding and allergic reactions. If
an infant is switched sooner than one year, the practitioner should encourage the family to
resume use of formula or breast milk until the one year birthday. Despite the addition of table
foods or baby solid foods, formula and breast milk are still the dietary mainstay.

Meckel's diverticulum
intussusception
acute appendicitis
acute gastroenteritis
intussusception
Acute onset of abdominal pain requires immediate investigation. The nurse practitioner must be
able to distinguish between conditions that can safely be managed at home and those requiring
immediate referral. Meckel's diverticulum usually involves painless rectal bleeding. Acute
appendicitis can occur in infants and must be considered in the differential diagnosis. The pain
history of acute appendicitis is usually more continuous, and there is no palpable mass. Acute
gastroenteritis may involve intermittent pain and cramping, but more typically the child appears
ill, and vomiting and diarrhea play a more prominent role. The pain of intussusception is very
severe, with periods of well-being in between. There is frequently vomiting, however stools
initially are normal. Later stools can be like red jelly in appearance. A sausage shaped mass is
frequently palpable in the right upper quadrant and aids in diagnosis.
For the parents of an 8 month old, the MOST appropriate age-related anticipatory guidance
regarding safety includes which of the following?
cover electrical outlets, keep small objects out of reach, turn car seat to forward-facing position
keep medications out of reach, continue to use car seat in rear-facing position, cover electrical
outlets
