1. What is the first sign of puberty in boys?

• A. Enlargement of testes
• B. Decreased levels of testosterone
• C. Voice deepening
• D. Pubic hair

Correct answer: A

Rationale: The first sign of puberty in boys is typically the enlargement of the testes. This is due to the increase in production of testosterone, which leads to physical changes such as growth of the testes. Choice B, decreased levels of testosterone, is incorrect as puberty is marked by an increase in testosterone levels. Choice C, voice deepening, and choice D, pubic hair growth, usually occur later in the puberty process compared to testicular enlargement, making them incorrect answers.

2. Ongoing fluid losses can overwhelm the child’s ability to compensate, resulting in shock. What early clinical sign precedes shock?

• A. Tachycardia
• B. Slow respirations
• C. Warm, flushed skin
• D. Decreased blood pressure

Correct answer: A

Rationale: Tachycardia is an early sign of shock as the body tries to maintain cardiac output in the face of declining circulatory volume. Blood pressure often remains normal until late in the progression, at which point decompensated shock is occurring.

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

• A. Fruits
• B. Eggs
• C. Vegetables
• D. Meat

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.

4. A young mother asks if her 9-month-old can begin drinking cow’s milk instead of formula. You explain that:

• A. Cow’s milk is easier to digest than formula
• B. Breast milk or formula should be used for now because whole cow’s milk is not recommended for infants under 1 year
• C. As long as whole milk is given and not skim milk, it is okay
• D. Cow’s milk will decrease the chance of iron deficiency anemia

Correct answer: B

Rationale: Breast milk or formula should be used for now because whole cow’s milk is not recommended for infants under 1 year. Cow’s milk is not suitable for infants under 1 year of age as it lacks essential nutrients like iron and can lead to iron deficiency. Therefore, it is important to continue with breast milk or formula to ensure the baby's nutritional needs are met. Choice A is incorrect as cow’s milk is not easier to digest than formula for infants. Choice C is incorrect as the type of milk, whether whole or skim, is not the primary concern at this age. Choice D is incorrect as cow’s milk can actually increase the risk of iron deficiency anemia in infants.

5. One of the most critical needs of the infant is control of body temperature. The nurse caring for a newborn warms all equipment that comes in direct contact with the newborn to help prevent which type of heat loss?

• A. Convection
• B. Evaporation
• C. Conduction
• D. Radiation

Correct answer: C

Rationale: The correct answer is Conduction (choice C). Conduction heat loss occurs when the newborn’s skin comes into direct contact with a cooler surface, so warming equipment helps prevent this. Choice A, Convection, is the transfer of heat through air or water currents, not direct contact. Choice B, Evaporation, is the loss of heat through moisture on the skin evaporating, not direct contact. Choice D, Radiation, is the transfer of heat in the form of waves or particles, not direct contact.
