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. The nurse is assessing a 3-day-old breastfed newborn who weighed 3400 g (7 pounds, 8 oz) at birth. The infant’s mother is now concerned because the infant weighs 3147 g (6 pounds, 15 oz). The most appropriate nursing intervention is what?

• A. Recommend supplemental feedings of formula.
• B. Explain that this weight loss is within normal limits.
• C. Assess the child further to determine the cause of excessive weight loss.
• D. Encourage the mother to express breast milk for bottle-feeding the infant.

Correct answer: B

Rationale: A neonate normally loses about 10% of the birth weight by age 3 to 4 days. The birth weight is usually regained by the 10th day of life. In this case, the weight loss from 3400 g to 3147 g is within the expected range. Therefore, the most appropriate action is to explain to the mother that this weight loss is within normal limits. Choice A is incorrect because supplemental feedings of formula are not indicated for this expected weight loss in a breastfed newborn. Choice C is incorrect as there is no evidence to suggest excessive weight loss at this point. Choice D is unnecessary at this stage and may not align with the current situation of normal weight loss post-birth.

3. The nurse suspects that a child has ingested some type of poison. What clinical manifestation would be most suggestive that the poison was a corrosive product?

• A. Tinnitus
• B. Disorientation
• C. Stupor, lethargy, and coma
• D. Edema of the lips, tongue, and pharynx

Correct answer: D

Rationale: Edema of the lips, tongue, and pharynx is a characteristic sign of corrosive poisoning, indicating damage to mucous membranes from ingestion of a caustic substance. Other symptoms may vary depending on the poison but are not as specific to corrosive ingestion.

4. What amount of fluid loss occurs with moderate dehydration?

• A. <50 ml/kg
• B. 50 to 90 ml/kg
• C. <5% total body weight
• D. >15% total body weight

Correct answer: B

Rationale: Moderate dehydration is typically defined as a loss of 50 to 90 mL/kg of body weight. This amount reflects significant fluid loss that requires medical attention but is not yet severe.

5. A toddler’s mother calls the nurse because she thinks her son has swallowed a button type of battery. He has no signs of respiratory distress. The nurse’s response should be based on which premise?

• A. An emergency laparotomy is very likely.
• B. The location needs to be confirmed by radiographic examination.
• C. Surgery will be necessary if the battery has not passed in the stool in 48 hours.
• D. Careful observation is essential because an ingested battery cannot be accurately detected.

Correct answer: B

Rationale: Radiographic examination is essential to confirm the location of the battery, as it can cause significant damage, particularly if lodged in the esophagus. Immediate surgery may be required depending on its location and the potential for causing harm.
