Matching: Upper airway infection

Correct Answer: A

Rationale: The correct answer is A) Parainfluenza virus. In pediatric respiratory disorders, upper airway infections are commonly caused by viral agents like Parainfluenza virus. This virus is known to cause croup, a condition characterized by barking cough and inspiratory stridor. Option B) Staphylococcus aureus is a bacterial pathogen, not typically associated with upper airway infections in pediatrics. It is more commonly linked to skin and soft tissue infections. Option C) Persistent fetal circulation is a cardiovascular condition seen in newborns, not related to upper airway infections. Option D) Croup is a condition caused by viral infections, particularly by the Parainfluenza virus. It presents with symptoms like barking cough and inspiratory stridor. Educationally, understanding the etiology of pediatric respiratory disorders is crucial for nurses caring for children. Knowing the common pathogens involved in upper airway infections helps in accurate diagnosis and appropriate management. Nurses should be able to differentiate between viral and bacterial causes to provide effective care and educate families on preventive measures.

Correct Answer: D

Rationale: The correct answer is D) hereditary hemorrhagic telangiectasia. In this case, the 12-year-old male presenting with recurrent unilateral epistaxis for 6 months is indicative of this condition. Hereditary hemorrhagic telangiectasia (HHT) is a genetic disorder characterized by abnormal blood vessel formation that leads to recurrent, spontaneous nosebleeds (epistaxis) due to fragile blood vessels in the nose. Option A) juvenile nasopharyngeal angiofibroma is a benign tumor that typically presents with unilateral nasal obstruction and epistaxis, but it is more common in adolescent males. Option B) von Willebrand disease is a bleeding disorder characterized by a deficiency or dysfunction of von Willebrand factor, resulting in prolonged bleeding time. While it can present with epistaxis, the chronicity and unilateral nature of the symptoms in this case are more indicative of HHT. Option C) idiopathic thrombocytopenic purpura is a condition characterized by low platelet count leading to increased bleeding tendencies, but it typically presents with mucocutaneous bleeding and petechiae rather than recurrent unilateral epistaxis. Educationally, understanding the differential diagnosis of recurrent epistaxis in pediatric patients is crucial for nurses caring for children with respiratory disorders. Recognizing the clinical presentation of HHT can guide appropriate diagnostic tests and interventions, highlighting the importance of a comprehensive assessment and knowledge of pediatric respiratory conditions in nursing practice.

Correct Answer: B

Rationale: In this quiz question regarding common causes of the common cold, the correct answer is B) reovirus. Reovirus is not a common cause of the common cold in pediatric patients. The other options, A) respiratory syncytial virus, C) coronavirus, and D) parainfluenza virus, are all well-known pathogens associated with respiratory infections in children. Respiratory syncytial virus is a common cause of bronchiolitis and pneumonia in infants and young children. Coronaviruses, such as the one responsible for COVID-19, can also cause symptoms resembling the common cold. Parainfluenza virus is another common viral cause of respiratory infections in children, often leading to croup. Educationally, understanding the common pathogens causing respiratory illnesses in pediatric patients is crucial for nurses caring for children. By differentiating between these viruses, nurses can provide appropriate care, implement infection control measures, and educate families on prevention strategies. This knowledge helps in the accurate assessment and management of pediatric respiratory disorders, ultimately improving patient outcomes.

Correct Answer: D

Rationale: In this question, option D is the correct answer because it states that all the pathogens mentioned (H influenzae type b, H influenzae untypable, and M catarrhalis) are responsible for the acute deterioration in the patient. This choice indicates that all the pathogens play a role in the patient's condition. Option A, H influenzae type b, is a common pathogen known to cause respiratory infections in children, especially pneumonia and meningitis. Option B, H influenzae untypable, refers to non-typeable strains of Haemophilus influenzae which can also cause respiratory infections. Option C, M catarrhalis, is another bacterium that can cause respiratory infections in children. From an educational standpoint, understanding the different pathogens responsible for respiratory disorders in pediatric patients is crucial for nurses caring for these vulnerable populations. Recognizing the specific pathogens involved helps in effective treatment and management of respiratory conditions in children. This knowledge also aids in infection control practices to prevent the spread of these pathogens in healthcare settings.

Correct Answer: D

Rationale: In cystic fibrosis (CF), a genetic disorder affecting the respiratory and digestive systems, wheezing respirations and a dry, nonproductive cough are common early symptoms. These symptoms result from the thick, sticky mucus produced in the airways, leading to airway obstruction and inflammation. Therefore, option D is correct as it aligns with the typical early respiratory manifestations of CF. Option A, developing a barrel-shaped chest, is associated with chronic obstructive pulmonary disease (COPD) rather than CF. Option B, chronic productive cough, is more indicative of conditions like bronchitis or chronic bronchial infections, which can occur in CF but are not typically early symptoms. Option C, bronchiectasis, is a complication of CF due to chronic infection and inflammation but is not an early symptom parents should expect. In an educational context, understanding the early respiratory symptoms of CF is crucial for parents and healthcare providers to facilitate early diagnosis and intervention. By recognizing these symptoms, prompt management can be initiated to improve the quality of life and long-term outcomes for children with CF.
