Nursing Elites

1. The mother of an infant diagnosed with bronchiolitis asks the nurse what causes the disease. How should the nurse respond?

• A. Respiratory syncytial virus (RSV)
• B. Haemophilus influenzae
• C. Parainfluenza
• D. Rotavirus

Correct answer: A

Rationale: The correct answer is A: Respiratory syncytial virus (RSV). RSV is the most common cause of bronchiolitis, especially in infants. Bronchiolitis is characterized by inflammation of the small airways in the lungs. Choice B, Haemophilus influenzae, is a bacterium that can cause respiratory infections but is not the primary cause of bronchiolitis. Choice C, Parainfluenza, is a common viral infection that can cause croup and other respiratory illnesses but is not the main cause of bronchiolitis. Choice D, Rotavirus, is a virus that primarily affects the gastrointestinal system, causing diarrhea and vomiting, and is not associated with bronchiolitis.

2. Which nursing intervention should be included in the postoperative care of a child following a tonsillectomy?

• A. Encourage the child to blow the nose gently
• B. Notify the physician if mucus is observed in the emesis
• C. Position the child supine in the immediate postoperative period
• D. Avoid giving citrus juice

Correct answer: D

Rationale: The correct answer is D: 'Avoid giving citrus juice.' Citrus juice can irritate the throat after a tonsillectomy, so it should be avoided. Choice A is incorrect because blowing the nose gently is not a recommended intervention following a tonsillectomy. Choice B is incorrect as mucus in emesis is not uncommon postoperatively and does not necessarily require physician notification. Choice C is incorrect as positioning the child supine immediately postoperatively can increase the risk of airway obstruction and should be avoided.

3. Following treatment for iron deficiency anemia, the physician orders lab tests. Which lab value would indicate an improvement in the child’s condition?

• A. Low hemoglobin
• B. Normal platelet count
• C. High reticulocyte count
• D. Low hematocrit

Correct answer: C

Rationale: A high reticulocyte count indicates that the bone marrow is producing more red blood cells, which is a sign of recovery from anemia as the body replenishes its iron stores and increases hemoglobin levels. Low hemoglobin (Choice A) would indicate ongoing anemia rather than improvement. A normal platelet count (Choice B) and low hematocrit (Choice D) are not specific indicators of improvement in iron deficiency anemia.

4. What is an appropriate screening test for hearing that the nurse can administer to a 5-year-old child?

• A. Rinne test
• B. Weber test
• C. Pure tone audiometry
• D. Eliciting the startle reflex

Correct answer: C

Rationale: Pure tone audiometry is an appropriate and effective screening test for hearing in a 5-year-old child, helping to assess the ability to hear various frequencies and volumes.

5. A four-year-old boy is admitted to the hospital with leg pain and fever. He is pale-looking and has bruises over various areas of his body. The physician suspects acute lymphoblastic leukemia (ALL). Which test would be used to confirm the diagnosis?

• A. Bone marrow aspirate
• B. Red blood cell count
• C. Lumbar puncture
• D. Bone scan

Correct answer: A

Rationale: A bone marrow aspirate is the definitive test to confirm acute lymphoblastic leukemia (ALL) in this case. It allows for the examination of leukemic cells in the bone marrow, providing a direct assessment of the disease. Red blood cell count (Choice B) is not specific for diagnosing leukemia but may show anemia commonly seen in leukemia patients. Lumbar puncture (Choice C) is used to assess central nervous system involvement, not primarily for confirming ALL. Bone scan (Choice D) is not a standard diagnostic test for ALL and is mainly used for evaluating bone metastases in other conditions.
