Q

An 8-year-old African American girl is evaluated for complaints of fatigue, shortness of breath, rash, and cough for 3 weeks. A chest radiograph reveals small bilateral pleural effusions, pneumonitis, and cardiomegaly. Which of the following diagnosis should be considered in this child? a. Mycoplasma (e.g., walking) pneumonia. b. SLE. c. Cardiomyopathy. d. Localized scleroderma.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (p. 1358). Wolters Kluwer Health. Kindle Edition.

A

Answer: B A diagnosis of SLE is made by meeting at least 4 out of 11 criteria that are set forth by the American College of Rheumatology. SLE must be considered in early stages of presentation to prevent risk for increased organ damage when diagnosed late.

Q

A 15-month-old female toddler is seen in clinic with fever of 104°F for 2 days, generalized morbilliform rash, and an otherwise normal examination. Which of the following is the most appropriate course of action? a. Prescribe antipyretics and request follow-up in 3 days if no resolution of fever and/or rash. b. Prescribe antipyretics and reassure parents the most likely cause is viral, with fever and rash resolving spontaneously. c. Obtain a urinalysis, urine culture, and CBC. d. Obtain cerebrospinal fluid (CSF) and blood cultures.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (p. 1360). Wolters Kluwer Health. Kindle Edition.

A

Answer: A Prompt recognition is key to the diagnosis and treatment of Kawasaki disease. Typical and atypical classifications require 2 to 6 criteria be met, which include fever for at least 4 days in addition to the other manifestations. Antipyretics should be prescribed for comfort as well as for control of high fever, and reevaluation should be completed after 4 days of persistent fever to evaluate for other potential causes of fever and rash. Laboratory studies can assist in the evaluation of Kawasaki disease when the fever persists for 4 or more days.

Q

A 4-year-old is seen in the emergency department with a history of fever for 1 week up to 106°F, conjunctivitis, complaints of generalized pain, nausea, and vomiting. The clinician suspects Kawasaki disease. Which of the following tests should be ordered first to assist in determining the diagnosis? a. Chest radiography, pancreatic function tests, and CSF cultures. b. CBC; blood, urine, and CSF cultures. c. Echocardiography, urine and blood cultures. d. CBC; liver and pancreatic function tests and inflammatory markers.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (pp. 1360-1361). Wolters Kluwer Health. Kindle Edition.

A

Answer: D Laboratory findings consistent for Kawasaki disease include elevated CRP and ESR, thrombocytosis, anemia, elevated transaminases, as well as pancreatitis. Aseptic meningitis is also seen, although less frequently. Echocardiography should be completed to evaluate for coronary aneurysms and to rule out pericardial effusion, although the absence of coronary abnormalities does not rule out Kawasaki disease. Echocardiography will be needed if the laboratory evaluation and clinical signs suggest Kawasaki disease; however, it is not needed in this stage of the evaluation.

70
Q

management of HLH

A

*Human leukocyte antigen (HLA) typing is usually sent early in the treatment course for possible stem cell transplantation. *Induction therapy is generally with dexamethasone, etoposide +/− cyclosporine, with treatment weaning over 8 weeks.
*In patients with genetic/familial predisposition or recurrent/refractory disease, an allogeneic stem cell transplant with a HLA-matched donor is indicated.
* Risk of recurrence is much higher in this patient population.
* Caution must be used with a HLA-matched sibling, as they may also have the genetic/familial predisposition to HLH.

Q

A 5-month-old female infant recently adopted from Southeast Asia presents to the Emergency Department (ED) with pallor, failure to thrive, frontal bossing, hepatosplenomegaly, and jaundice. In considering differential diagnoses, the most helpful diagnostic study results to indicate β-thalassemia would be: a. Absence of hemoglobin A on electrophoresis and microcytic anemia. b. Presence of hemoglobin SS on electrophoresis with normal RBC indices. c. Normal hemoglobin electrophoresis with hypochromic/microcytic anemia. d. Presence of fetal hemoglobin on electrophoresis with normal MCV.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (p. 879). Wolters Kluwer Health. Kindle Edition.

A

Answer: A A hallmark finding of β-thalassemia is absence of hemoglobin A on electrophoresis, which is the study of choice for diagnosis along with microcytic anemia.

A four-year old presents to the emergency room (ED) with constipation, abdominal pain and distension, and general malaise. Of note, she also has periorbital ecchymosis, although her caregiver does not recall trauma. The child is hypertensive and ill appearing on initial examination. Which of the following is highest on the differential diagnosis? a. Wilm tumor. b. Ewing sarcoma. c. Hodgkin Lymphoma. d. Neuroblastoma.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (pp. 885-886). Wolters Kluwer Health. Kindle Edition.

A

Answer: D Although this patient could have Wilm tumor, the description portrays an ill child with a mass that is impairing her bowel habits. Additionally, she has periorbital ecchymosis, which is likely secondary to metastasis. The hypertension is the result of a sympathetic nervous system tumor arising from the adrenal medulla. Based on this patient’s age and the description of her clinically, Ewing sarcoma and Hodgkin Lymphoma are less likely.

96
Q

Children receiving anticoagulation with unfractionated heparin should be monitored: a. Using PT/INR with a goal of 2 to 3. b. With Factor X level with a goal of 0.5 to 1. c. For heparin-induced thrombocytopenia. d. With Anti-Xa with a goal of 0.5.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (p. 886). Wolters Kluwer Health. Kindle Edition.

A

Answer: D Unfractionated heparin such as Enoxaparin is used for anticoagulation in many instances instead of heparin or warfarin as it is just as effective with consistent therapy. Factor Xa level is the monitor for effect, but is not always warranted for every patient.

Q

The parents of an 18-month-old female are concerned that her abdomen was distended while bathing her last night. She has no other signs or symptoms. On examination, a large right-sided abdominal mass is palpated. Which of the following findings would lead to a higher suspicion of Wilms’ Tumor? a. Multiple café-au-lait lesions. b. Hemihypertrophy. c. Ptosis of the right eye. d. Multiple petechiae and ecchymoses.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (p. 887). Wolters Kluwer Health. Kindle Edition.

A

Answer: B Congenital hemihypertrophy is a condition of unknown etiology characterized by unilateral overgrowth of part or all of one side of the body, including limbs. Hemihypertrophy is a finding associated with Beckwith–Weidemann Syndrome (BWS). Patients with BWS have a higher risk of developing WIlms’ tumor.

Q

31.A 9-month-old with a history of prematurity and chronic lung disease was admitted for acute respiratory failure due to RSV bronchiolitis. History includes a 1-month NICU stay with a diagnosis of heparin induced thrombocytopenia during that time. An ultrasound for edema of one lower extremity confirmed an acute nonocclusive thrombus in the left common femoral vein. Best choice for anticoagulation will be: a. Heparin infusion. b. Enoxaparin. c. Aspirin. d. Bivalirudin.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (p. 892). Wolters Kluwer Health. Kindle Edition.

A

Answer: D Bivalirudin is a direct thrombin inhibitor and preferred choice of anticoagulation in a patient with a history of HIT. Enoxaparin is a low molecular weight heparin, and aspirin would not be an appropriate anticoagulant for deep vein thrombosis.

108
Q

Which of the following tests would be reasonable to perform in the initial diagnostic evaluation HLH of this patient? a. Karyotype of the patient. b. Genetic testing for gene defects associated HLH, such as Perforin and Syntaxin-11. c. HLA typing of the patient. d. Bone marrow biopsy.

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (p. 894). Wolters Kluwer Health. Kindle Edition.

A

Answer: C This patient has a family history suspicious for a genetic/familial predisposition to HLH. It is reasonable to assume that this patient will ultimately proceed to a stem cell transplantation, in which case obtaining HLA typing early is critical in order to have time to find a proper HLA match. Genetic testing for gene defects in Perforin, Syntaxin-11 are appropriate, but not in the initial evaluation, and should be performed with the guidance of a pediatric hematologist/oncologist. Karyotype of the patient is not indicated in the evaluation for HLH.

109
Q

The patient in question #2 (above) is started on HLH therapy. The caregivers ask which therapy will be used, and what the following steps will be? Which of the following is the correct response to these questions? a. Therapy will be with dexamethasone for 1 month, followed by etoposide for another month, then reevaluation. b.Therapy will be with dexamethasone and etoposide for 2 months, then if in remission, will likely proceed to a stem cell transplantation if a donor is available. c. As soon as the patient is stable, a stem cell transplantation with a HLA-matched donor is the next step. d. The patient’s underlying infection will be treated, and then the body will be allowed to “correct itself.”

Kline, Andrea M.; Haut, Catherine. Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner (p. 895). Wolters Kluwer Health. Kindle Edition.

A

Answer: B Steroids are seldom used alone in treating HLH. Treatment duration is 8 weeks of upfront therapy, with stem cell transplantation as an option to those with a high risk of HLH recurrence. Treating any concurrent infection will seldom make the immune activation in HLH completely “correct itself.”
