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. A healthy 24 month old can be expected to have achieved which of the following language milestones? counts three objects correctly speaks using 30 - 50 words states full name tells a story speaks using 30 - 50 words 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. 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. A 10 month old has had apparent abdominal pain for the past 4 hours. During episodes of pain, the infant screams inconsolably and draws his legs towards the abdomen, has vomited twice, but has had no diarrhea. Between episodes the infant is calm and quiet. The MOST likely diagnosis is: 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 avoid finger foods that can be easily aspirated, teach stranger safety, place Mr. Yuk stickers on toxic materials keep matches out of reach, place Mr. Yuk stickers on toxic materials, teach stranger safety keep medications out of reach, continue to use car seat in rear-facing position, cover electrical outlets An 8 month old is beginning to cruise, crawl and develop a fine pincer grasp. Keeping medications and small objects out of reach in this age group assists in avoiding choking or toxic ingestions. Covering electrical outlets helps to prevent accidental electrocution while the infant is exploring his surroundings. An infant should maintain the rear-facing position of the car seat until the age of one year. An 8 month old is not at a developmental level to understand stranger caution nor Mr. Yuk stickers. Keeping matches out of reach is important, although it is not as likely that an 8 month old would have the dexterity to strike a match. The INITIAL treatment for a school-age female with well-demarcated erythema and mucoid discharge in the vulva area includes: discontinuation of bubble baths. instruction on front to back cleansing. oral penicillin. topical Premarin. instruction on front to back cleansing. Vulvovaginitis is the most common genital complaint among prepubertal girls due to the thin hypo estrogenized mucosal tissue with an alkaline pH, small labia minora, and location proximal to the anus. Vulvovaginitis, caused by streptococcal bacterial infections, is identified by welldemarcated areas of erythema with a mucoid discharge. A 10-day regimen of oral penicillin or amoxicillin is the treatment for a streptococcal infection which is the most common organism. Vulvovaginitis can be caused by poor hygiene in girls who may be wiping inadequately or inappropriately (e.g. from back to front), leading to local irritation. Prepubertal females should be instructed in proper hygiene and wiping of perianal area. Soaps, shampoos, and bubble baths are the most common cause of dysuria due to chemical urethritis. Topical Premarin is used in the initial treatment of labial adhesions. Emphasis on promoting healthy behavioral changes for the overweight child should include which of the following? establishing family goals maintaining family holiday meal rituals weighing child daily using weight loss as a sign of success establishing family goals Effective weight loss planning and implementation need to involve the entire family. Emphasis should be placed on family change and family goals as children will copy their parents' behaviors. In addition, parents have control over some aspects of the change process that can occur in relation to goals and meals in the home. Daily weights are not recommended, and weight loss should not be used as the measure of success. Changing behaviors is a success by itself and should be celebrated. New family and holiday rituals should be established for a focus on non-food related events. Early fractures and Salter I fractures can be missed initially; repeat films 10 to 14 days after an injury may be necessary to confirm the diagnosis of a fracture. Because this child is still symptomatic with complaints of pain and point tenderness after the fall, follow up radiographic studies are indicated. Bone scanning is useful in diagnosing stress fractures, but not appropriate in this situation with a history of a known injury. It is likely that this is a simple fracture that will heal quickly with immobilization, with no disruption to bone growth. If the follow-up radiograph showed evidence of trauma to growth plates, a referral to an orthopedic surgeon would then be appropriate.
