1. A 2-month-old infant is brought to the clinic for a routine check-up.

The nurse assesses the infant's growth and development using the

Denver II Developmental Screening Test. Which of the following

findings would indicate a need for further evaluation?

a) The infant can lift head 45 degrees when prone.

b) The infant can follow a moving object past midline.

c) The infant can smile spontaneously and responsively.

d) The infant can grasp a rattle when placed in hand.*

Rationale: The correct answer is d. The ability to grasp a rattle when

placed in hand is a fine motor skill that is expected at 4 months of age,

not 2 months. The other options are normal developmental milestones

for a 2-month-old infant.

2. A 6-month-old infant is diagnosed with bronchiolitis caused by

respiratory syncytial virus (RSV). The nurse provides education to the

parents about the management of the condition at home. Which of the

following statements by the parents indicates a need for further

teaching?

a) "We will keep our baby well hydrated with breast milk or formula."

b) "We will use a bulb syringe to clear our baby's nose before

feeding."

c) "We will give our baby acetaminophen for fever and pain relief."

d) "We will use a cool-mist humidifier in our baby's room."*

Rationale: The correct answer is d. A cool-mist humidifier is not

recommended for infants with bronchiolitis because it may increase

airway inflammation and mucus production. A warm-mist humidifier

or vaporizer may be more beneficial. The other statements are

appropriate for the home care of an infant with bronchiolitis.

3. A 9-month-old infant is admitted to the hospital with dehydration

due to gastroenteritis. The nurse monitors the infant's fluid status
