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. A child is admitted with renal failure. Which of these findings should the nurse expect?

• A. Decreased BUN
• B. Azotemia and oliguria
• C. Increased glomerular filtration rate (GFR)
• D. Polyuria and elevated creatinine clearance

Correct answer: B

Rationale: Azotemia (elevated BUN and creatinine) and oliguria (reduced urine output) are classic signs of renal failure, indicating impaired kidney function. In renal failure, the kidneys are unable to effectively filter waste products, leading to an increase in BUN and creatinine levels in the blood. Additionally, oliguria occurs due to decreased kidney function. Increased GFR (Choice C) is not expected in renal failure as it signifies improved kidney function, which is not the case in renal failure. Polyuria and elevated creatinine clearance (Choice D) are not typical findings in renal failure. Polyuria is more commonly associated with conditions like diabetes insipidus, while elevated creatinine clearance would indicate increased kidney function, which is contrary to the impaired function seen in renal failure.

3. The nurse is caring for an infant who was born 24 hr ago to a mother who received no prenatal care. The infant is a poor feeder but sucks avidly on his hands. Clinical manifestations also include hyperactive reflexes, tremors, sneezing, and a high-pitched shrill cry. What does the nurse consider as a possible diagnosis for this infant?

• A. Seizure disorder
• B. Narcotic withdrawal
• C. Placental insufficiency
• D. Meconium aspiration syndrome

Correct answer: B

Rationale: In this case, the infant's symptoms are consistent with narcotic withdrawal. Infants exposed to drugs in utero may display withdrawal symptoms starting around 12 to 24 hours post-birth. The presentation often includes hyperactive reflexes, tremors, sneezing, high-pitched shrill cry, poor feeding, and sucking avidly on hands. Signs such as loose stools, tachycardia, fever, projectile vomiting, sneezing, and generalized sweating are common. These symptoms are not indicative of a seizure disorder. Placental insufficiency typically leads to a small-for-gestational-age child, which is not mentioned in the scenario. Meconium aspiration syndrome primarily presents with respiratory distress, not the symptoms described in this case.

4. An anxious 12-year-old child receives an injection from the nurse and sighs with relief when it is done. After a moment of reflection, the girl asks the nurse, 'Is it hard to give someone an injection?' This child’s question is evidence that the child has developed which cognitive skill?

• A. Conservation
• B. Accommodation
• C. Decentering
• D. Class inclusion

Correct answer: C

Rationale: The correct answer is C: Decentering. Decentering is the ability to consider multiple aspects of a situation, which the child's question demonstrates. In this scenario, the child's question shows that she is thinking beyond her own experience and considering the difficulty or complexity of giving an injection from the nurse's perspective. Choices A, B, and D are incorrect. Conservation refers to understanding that certain properties of an object remain the same despite changes in its appearance. Accommodation is the process of adjusting existing knowledge or creating new mental categories to incorporate new information. Class inclusion involves understanding the relationship between a whole set and its subsets, which is not demonstrated in the child's question.

5. Which condition is characterized by a harsh, barking cough in children?

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

Correct answer: C

Rationale: Croup is the correct answer. It is characterized by a harsh, barking cough due to inflammation of the upper airways, specifically the larynx and trachea. Asthma (Choice A) often presents with wheezing and shortness of breath, not a barking cough. Bronchiolitis (Choice B) typically causes wheezing and respiratory distress in infants. Pneumonia (Choice D) manifests with symptoms such as fever, productive cough, and chest pain, but not usually a barking cough.
