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. What condition is often associated with severe diarrhea?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: Severe diarrhea can lead to a loss of bicarbonate, resulting in metabolic acidosis. This is a common complication of prolonged or severe diarrhea, especially in children.

3. During an otoscopic examination on an infant, in which direction is the pinna pulled?

• A. Up and back
• B. Up and forward
• C. Down and back
• D. Down and forward

Correct answer: C

Rationale: For infants, the pinna is pulled down and back to straighten the ear canal and allow proper visualization of the tympanic membrane during otoscopic examination.

4. What term describes the invagination of one segment of bowel within another?

• A. Atresia
• B. Stenosis
• C. Herniation
• D. Intussusception

Correct answer: D

Rationale: Intussusception is the correct answer. It refers to the condition where one segment of the bowel folds into another, leading to an obstruction. Atresia (Choice A) is the absence or abnormal closure of a normal opening or tubular structure. Stenosis (Choice B) is the narrowing of a passage in the body. Herniation (Choice C) is the abnormal protrusion of an organ or tissue through a defect in its surrounding walls. Intussusception is a medical emergency commonly observed in infants and young children and necessitates prompt intervention to prevent severe complications.

5. What term is appropriate terminology to use for an infant whose intrauterine growth rate was slowed and whose birth weight falls below the 10th percentile on intrauterine growth charts?

• A. Postterm
• B. Postmature
• C. Low birth weight
• D. Small for gestational age

Correct answer: D

Rationale: The correct answer is D, 'Small for gestational age.' A small for gestational age, or small-for-date, infant is any child whose intrauterine growth rate was slowed and whose birth weight falls below the 10th percentile on intrauterine growth curves. Choices A and B, 'Postterm' and 'Postmature,' refer to infants born after 42 weeks of gestational age regardless of birth weight, and do not specifically address growth rate. Choice C, 'Low birth weight,' refers to infants with a birth weight less than 2500 g (5.5 pounds) regardless of gestational age, which is a different classification compared to being small for gestational age.
