Q

You have been Ava’s PCP since she was 5 years-old. At that time, Ava had aczema and coughing and wheezing. Ava’s mother has asthma and, through history taking and exam, you diagnosed asthma in Ava, too. You have examined Ava frequently to adjust medications, but now she is stable. She consistently takes her medication and uses her Flovent inhaler daily. Her mother diligently keeps the house clean, especially the bedroom Ava shares with her sister. You are ready to step down Ava’s medication therapy, according to the National Heart, Lung, and Blood Institute’s step wise approach. How often should you examine Ava during this step-down period?

Every month
Every three months
Every year
Every six months

A

EVERY 3 MONTHS

Asthma is highly variable over time. See patients:
Every 2-6 weeks while gaining control
Every 1-6 months to monitor control
Every 3 months if step down in therapy is anticipated.”

Q

ou are evaluating a 9-year-old- girl in an urgent care clinic for a rash. Eight days ago, she was evaluated and treated 8 days ago for acute otitis media with oral amoxicillin and now, with the rash appearing, the mother is concerned about an allergic reaction to penicillin.

PE: On physical exam her temperature is 101, HR 94, RR 23, and BP 104/58. She has a diffuse symmetric urticaria, which her mother reports started on her abdomen and then spread outwards. She has a serpiginous rash at the interface of the dorsal and palmar aspect of the hands and feet. Her wrists, elbows, knees, and ankles are swollen and painful to move. She has periorbital edema but clear conjunctiva. She also has anterior and posterior cervical and axillary lymphadenopathy that is mildly tender.

What type of reaction is this?

Type III hypersensitivity reaction
Type I hypersensitivity reaction
Type II hypersensitivity reaction
Type IV hypersensitivity reaction

A

Type III hypersensitivity reaction

a beard distribution.

20
Q

A pomadal distribution

A

occurs along the temple and forehead, as a result of pomades or oil-based cosmetics.

21
Q

An adolescent has acne characterized by papules and pustules mostly on the forehead and chin. What will the primary care pediatric nurse practitioner prescribe?

Benzoyl peroxide applied twice daily
Azelaic acid applied daily at nighttime
Tretinoin applied nightly after washing the face
Topical erythromycin with benzoyl peroxide

A

Topical erythromycin with benzoyl peroxide
Topical antibiotics combined with BPO are more effective than either drug alone and are especially effective in mild to moderate inflammatory acne or as adjunctive therapy with oral antibiotics. Azelaic acid is useful in persons with sensitive or dark skin and used for non-inflammatory acne. Topical antibiotics are best used in conjunction with BPO. Tretinoin is a keratolytic, useful for non-inflammatory acne.

22
Q

An African-American child has recurrent tinea capitis and has just developed a new area of alopecia after successful treatment several months prior. When prescribing treatment with griseofulvin and selenium shampoo, what else will the primary care pediatric nurse practitioner do?

Monitor CBC, LFT, and renal function during therapy.
Order oral prednisone daily for 5 to 14 days.
Prescribe oral itraconazole or terbinafine.
Perform fungal cultures on family members and pets.

A

Perform fungal cultures on family members and pets.
Because asymptomatic carriers may be present in the household, family members and pets should be cultured. It is not necessary to monitor lab work with griseofulvin unless there is a change in clinical status, due to the favorable safety profile of griseofulvin. Prednisone is used when severe inflammation is present. Oral itraconazole or terbinafine is used if resistance to griseofulvin occurs; this child has responded to griseofulvin.

23
Q

An infant is brought to clinic with bright erythema in the neck and flexural folds after recent treatment with antibiotics for otitis media. What is the treatment for this condition?

Topical keratolytics and topical antibiotics for 7 to 10 days
Topical nystatin cream applied several times daily until the rash is gone
1% hydrocortisone cream to affected areas for 1 to 2 days
Oral fluconazole 6 mg/kg on day 1, then 3 mg/kg/dose for 14 days

A

Topical nystatin cream applied several times daily .

Candida skin infections can occur in intertriginous areas in the neck, axilla, and groin, and appear as a bright erythematous rash. Topical nystatin is first-line therapy.

Fifteen percent hydrocortisone is used if inflammation is severe but not instead of topical antifungal therapy.

Oral fluconazole is used if resistant to treatment.

Keratolytics and antibiotics are used to treat superficial folliculitis.

24
Q

Michael has an area of inflammation on the neck that began after wearing a hand-made necklace. On examination, the skin appears chafed with mild erythematous patches. The lesions are very itchy. What is an appropriate initial treatment? Choose the two best answers.

Topical corticosteroids applied 2 to 3 times daily
Oral antihistamines given 4 times daily
Burow solution soaks and cool compresses
Application of a lanolin-based emollient

A

Topical corticosteroids applied 2 to 3 times daily & Oral antihistamines given 4 times daily

Lanolin-based emollients are contraindicated when inflammation is present.

Burow solution soaks are useful for vesicular rashes.

Oral antihistamines are not indicated unless itching and scratching occur. This child is itching so an antihistamine would be appropriate.

25
Q

When prescribing topical glucocorticoids to treat inflammatory skin conditions, the primary care pediatric nurse practitioner will:

initiate therapy with a high-potency glucocorticoid.
order lotions when higher potency is necessary.

Taper the strength of the steroids once the outbreak is fully controlled.

Use Class 1 topical steroid for the lowest potency.

A

Taper the strength of the steroids once the outbreak is fully controlled.

26
Q

Charley needs an occlusive dressing to treat lichen simplex chronicus.

Choose the three INCORRECT methods for applying the dressing.

Apply ointment before the dressing.

Plastic wrap should not be used.

The dressing should be applied to dry skin.

Change the dressing twice daily.

A

Plastic wrap should not be used.

The dressing should be applied to dry skin.

Change the dressing twice daily.

27
Q

A 14-year-old child has clusters of small, clear, tense vesicles with an erythematous base on one side of the mouth along the vermillion border, which are causing discomfort and difficulty eating. Which treatment will the primary care pediatric nurse practitioner not recommend as treatment?

Topical diphenhydramine and magnesium hydroxide

Topical acyclovir applied to lesions 4 times daily

Oral acyclovir 20 to 40 mg/kg/dose for 7 to 10 days
Mupirocin ointment applied to lesions 3 times daily

A

Mupirocin ointment applied to lesions 3 times daily

Mupirocin ointment is used for secondary bacterial infection.

28
Q

Ointments for psoriasis

A

Anthralin ointment is useful for plaques that are resistant to steroids.

Calcipotriol cream is effective for mild to moderate plaques, but when applied in excessive quantities over large areas can cause hypercalcemia.

Oral steroids are not indicated and may worsen symptoms by causing pustular flare.

Methotrexate is used for severe disease, and these symptoms indicate that this is moderate disease.

29
Q

A child has several circular, scaly lesions on the arms and abdomen, some of which have central clearing. The primary care pediatric nurse practitioner notes a smaller, scaly lesion on the child’s scalp. How will the nurse practitioner treat this child? Recommend OTC antifungal creams and shampoos.
Prescribe oral griseofulvin for 2 to 4 weeks.
Obtain scrapings of the lesions for fungal cultures.
Order prescription-strength antifungal creams.

A

Prescribe oral griseofulvin for 2 to 4 weeks.
Whenever tinea lesions occur on the scalp or nails, oral griseofulvin must be given for 2 to 4 weeks. Unless the infection is resistant to treatment, fungal cultures are not necessary. Topical medications alone are not effective for tinea capitus.

30
Q

A school-age child has several annular lesions on the abdomen characterized by central clearing with scaly, red borders. What is the first step in managing this condition?

Fluoresce the lesions with a Wood’s lamp.
Obtain fungal cultures of the lesions.
Treat empirically with antifungal cream.
Perform KOH-treated scrapings of the lesion borders.

A

Treat empirically with antifungal cream.
Unless the diagnosis is questionable, or if treatment failure occurs, tinea corporis is treated empirically with topical antifungal creams; therefore, it is not necessary to fluoresce the lesions, culture the lesions, or complete KOH testing of scrapings as an initial management step.

31
Q

A child is diagnosed with tinea versicolor. What is the correct management of this disorder?

Using ketoconazole 2% shampoo on lesions twice daily for 2 to 4 weeks
Oral antifungal treatment with fluconazole once weekly for 2 to 3 weeks
Application of selenium sulfide 2.5% lotion twice weekly for 2 to 4 weeks
Sun exposure for up to an hour every day for 2 to 4 weeks

A

Application of selenium sulfide 2.5% lotion twice weekly for 2 to 4 weeks
Selenium sulfide lotion or 1% shampoo is first-line treatment for children and younger adolescents. Oral antifungal medications are used in resistant cases in older adolescents. Sun exposure only intensifies lesions. Ketoconazole shampoo is used on older adolescents.

32
Q

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?

Consult hospitalist or pediatric neurology team emergently for further workup.
Reassure the parent that this is expected with cyclic vomiting syndrome

Begin using an anti-migraine medication to prevent headaches.
Prescribe ondansetron and lorazepam to help manage symptoms.

A

Consult hospitalist or pediatric neurology team emergentlyfor further workup.
This child has an abnormal neurologic examination, which is a red flag warranting referral for further workup for children with cyclic vomiting syndrome. Anti-migraine medications are used in children over age 12 years and therefore should not be used for this patient. Ondansetron and lorazepam may be useful for unrelenting nausea and poor sleep, but this child needs to be referred to evaluate neurologic symptoms. These signs are not expected.

33
Q

A school-age child has had abdominal pain for 3 months that occurs once or twice weekly and is associated with a headache and occasional difficulty sleeping, often causing the child to stay home from school. The child does not have vomiting or diarrhea and is gaining weight normally. The physical exam is normal. According to Bishop, what is included in the initial diagnostic work-up for this child?

CBC, ESR, CRP, and fecal calprotectin
Stool for H. pylori antigen and serum IgA, IgG, tTg

CBC, ESR, CRP, UA, stool for ova, parasites, and culture

CBC, ESR, amylase, lipase, UA, and abdominal ultrasound

A

CBC, ESR, amylase, lipase, UA, and abdominal ultrasound
Bishop suggests these labs as an initial approach in children suspected of having functional abdominal pain, along with a 3-day trial of a lactose-free diet. Fecal calprotectin is added if the child has changes in stool habits suggestive of inflammatory changes in the intestinal tract.

34
Q

The parent of a 3-month-old reports that the infant arches and gags while feeding and spits up undigested formula frequently. The infant’s weight gain has dropped to the 5th percentile from the 12th percentile. What is the best course of treatment for this infant?

Institute an empiric trial of acid suppression with a proton pump inhibitor (PPI).

Perform esophageal pH monitoring to determine the degree of reflux.

Reassure the parent that these symptoms will likely resolve by 12 to 24 months.

Begin a trial of extensively hydrolyzed protein formula for 2 to 4 weeks.

A

Begin a trial of extensively hydrolyzed protein formula for 2 to 4 weeks.
Formula-fed infants may be given a trial of a hydrolyzed protein formula to see if improvement occurs. An empiric trial of a PPI may be used in children and adolescents but is not recommended in infants. Esophageal pH monitoring may be performed in consultation with a specialist but not as first-line evaluation. The infant has warning signs of GERD that require further investigation and not just reassurance.

35
Q

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?

Empiric therapy for H. pylori (HP)
Administration of H2RA or PPI medications

Ordering an upper GI series

Referral for esophagogastroduodenoscopy (EGD)

A

Referral for esophagogastroduodenoscopy (EGD)
EGD is the procedure of choice in children for detecting PUD because it allows direct visualization of mucosa, localization of the source of bleeding, and collection of tissue specimens. Empiric therapy for HP is not recommended due to increased antibiotic resistance. An upper GI series may have false negative findings. Once peptic ulcer disease is diagnosed, H2RA or PPI medications are first-line drugs.
