Question 1 of 5
Assume you are evaluating the specificity of the indirect fluorescence antibody test for rapid diagnosis of Campylobacter enteritis. The number of normal persons tested is 150 and the test is positive in 30 persons. The specificity of this test is
Correct Answer: D
Rationale: Specificity = (True negatives / Total normals) * 100 = [(150 - 30) / 150] * 100 = 80%.
Question 2 of 5
Of the following, the WORST prognostic factor in pediatric osteosarcoma is
Correct Answer: B
Rationale: Poor histologic response to neoadjuvant chemotherapy is a strong predictor of poor prognosis.
Question 3 of 5
a definitive diagnosis of sickle cell disease is based on which diagnostic result
Correct Answer: D
Rationale: A definitive diagnosis of sickle cell disease is based on hemoglobin electrophoresis. This test separates the different types of hemoglobin based on their electrical charge, allowing for the detection of abnormal hemoglobin variants such as hemoglobin S, which is characteristic of sickle cell disease. A complete blood count (CBC) can show various abnormalities seen in sickle cell disease, but it is not specific for confirming the diagnosis. Bone marrow aspiration is not routinely used for diagnosing sickle cell disease. Blood chemistry tests may reveal some complications associated with sickle cell disease but do not confirm the condition itself. Hemoglobin electrophoresis is the gold standard for diagnosing sickle cell disease by identifying the specific hemoglobin variant characteristic of the disorder.
Question 4 of 5
For most children with enuresis, the only test recommended is
Correct Answer: C
Rationale: Urinalysis is the standard initial test for evaluating enuresis to rule out urinary tract infections or other conditions.
Question 5 of 5
A 3-month-old infant, born at 38 weeks of gestation, will hold a rattle if it is put in her hands, but she will not voluntarily grasp it. How should the nurse interpret this action?
Correct Answer: C
Rationale: At 3 months of age, most infants should be able to voluntarily grasp objects placed in their hands. This infant, who was born at 38 weeks of gestation, is showing signs of slight delay in development. Premature infants often have developmental delays, especially in motor skills, compared to full-term infants. The fact that the infant can hold a rattle if it is put in her hands is a positive sign, indicating that she is on the right track developmentally but might be a little behind schedule. Continuing to monitor the infant's progress and providing appropriate developmental stimulation can help promote further motor skill development. There is no indication at this point to suspect a significant developmental lag or a neurologic disorder like cerebral palsy without further assessment and observation.
