Which food should be introduced first to a 6-month-old infant?

Correct Answer: C

Rationale: Vegetables, particularly pureed ones, are often recommended as a first solid food for infants because they are easy to digest and less likely to cause allergies. Fruits can be introduced later due to their natural sweetness, while eggs and meat are typically introduced after fruits and vegetables as they may pose a higher risk of allergies.

Correct Answer: B

Rationale: A sunken fontanel is a classic sign of dehydration in infants, indicating a fluid volume deficit. In dehydration, the fontanel sinks due to decreased fluid volume in the body. Increased blood pressure (Choice A) is not typically associated with dehydration in infants. Decreased pulse rate (Choice C) is not a common finding in fluid volume deficit, as the body tries to increase the heart rate to compensate for decreased volume. Low urine specific gravity (Choice D) may be seen in dehydration, but it is not as specific or as easily observable as a sunken fontanel.

Correct Answer: A

Rationale: The Apgar score assesses a newborn's physical condition immediately after birth by evaluating heart rate, respiratory effort, muscle tone, reflex response, and color. Therefore, the correct answer is A. The other choices are incorrect because B) the Apgar score does not predict future intelligence, C) it does not measure parent and newborn interaction, and D) it is not used to determine gestational age.

Correct Answer: B

Rationale: The most effective method to prevent infection in newborns is by practicing proper hand hygiene by staff and family. This is crucial as it helps reduce the transmission of infectious agents, protecting vulnerable newborns. Using disposable items may help, but proper hand hygiene is more effective. Administering prophylactic antibiotics without a specific indication can lead to antibiotic resistance and is not recommended. Isolating the newborn from others is not practical and may not be necessary if proper hand hygiene is maintained.

Correct Answer: B

Rationale: The Denver II Developmental Screening Test is used to assess a child's development in four areas: personal-social, fine motor-adaptive, language, and gross motor skills. It helps identify children who may need further evaluation. Choice A, behavior problems, is incorrect as the Denver II primarily focuses on developmental milestones rather than behavior. Choice C, body mass index, is unrelated to the assessment of child development. Choice D, infection likelihood, is also not evaluated by the Denver II test.
