1. The presence of which pair of factors is a good predictor of a fluid deficit of at least 5% in an infant?

• A. Weight loss and decreased heart rate
• B. Capillary refill of less than 2 seconds and no tears
• C. Increased skin elasticity and sunken anterior fontanel
• D. Dry mucous membranes and generally ill appearance

Correct answer: D

Rationale: Dry mucous membranes and an ill appearance are good indicators of dehydration in infants, often correlating with a fluid deficit of at least 5%. Sunken fontanels and poor skin turgor are also indicative but were not options here.

2. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed
• B. Flexed posture favors heat loss
• C. A large body surface area favors heat loss to the environment
• D. A thick layer of subcutaneous fat provides excellent insulation

Correct answer: C

Rationale: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

3. If the needs of the infant are met in a loving, consistent manner, the infant will develop a sense of:

• A. Trust
• B. Love
• C. Independence
• D. Responsibility

Correct answer: A

Rationale: The correct answer is A: Trust. According to Erikson's psychosocial development theory, when infants receive consistent and loving care, they develop trust. This trust forms the basis of the first stage of psychosocial development, known as Trust vs. Mistrust. Trust is essential for healthy social and emotional development. Choice B, Love, is incorrect as it is more of an emotion than a developmental stage. Choice C, Independence, typically occurs later in development during Erikson's Autonomy vs. Shame and Doubt stage. Choice D, Responsibility, is also not the correct answer as it relates more to later stages of development where individuals develop a sense of duty and obligation.

4. According to Piaget, a 6-month-old infant should be in which developmental stage?

• A. Use of reflexes
• B. Primary circular reactions
• C. Secondary circular reactions
• D. Coordination of secondary schemata

Correct answer: C

Rationale: By 6 months, infants are usually in the stage of secondary circular reactions, where they start to intentionally repeat actions that bring pleasure or interesting results.

5. Which condition is characterized by a 'seal-like' barking cough in children?

• A. Croup
• B. Asthma
• C. Bronchitis
• D. Pneumonia

Correct answer: A

Rationale: Croup is the correct answer. Croup is characterized by a 'seal-like' barking cough due to inflammation and narrowing of the upper airways, particularly the larynx and trachea. It is most common in young children and can cause significant respiratory distress, especially at night. Treatment often includes humidified air and corticosteroids. Asthma (choice B) typically presents with wheezing and shortness of breath, not a barking cough. Bronchitis (choice C) is characterized by productive cough with mucus, not a barking cough. Pneumonia (choice D) often presents with fever, productive cough, and chest pain, not a barking cough.
