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

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. At what age is binocularity, the ability to fixate on one visual field with both eyes simultaneously, typically achieved?

Correct answer: B

Rationale: Binocularity, the ability to fixate on one visual field with both eyes simultaneously, is typically achieved by the age of 3 to 4 months. Achieving binocularity at 1 month is too early for most infants as their visual system is still developing. Similarly, 6 to 8 months and 12 months are beyond the normal age range for achieving binocularity, and delayed achievement could indicate potential issues like strabismus, which may lead to visual impairment if not addressed.

3. What is the most appropriate action for a healthcare provider if a child presents with suspected meningitis?

Correct answer: C

Rationale: Isolating the child is a priority to prevent the spread of infection until meningitis is confirmed or ruled out. Meningitis, particularly bacterial, is highly contagious and can lead to outbreaks if not properly managed. Isolation and prompt treatment are critical in preventing serious complications. Administering antibiotics immediately without confirmation of the diagnosis can be harmful if the cause is viral or non-infectious. Performing a lumbar puncture is a diagnostic procedure that should be done by a healthcare provider but is not the initial action when suspecting meningitis. Obtaining a complete blood count may be part of the diagnostic workup but is not the most appropriate initial action in suspected meningitis.

4. Superficial palpation of the abdomen is often perceived by the child as tickling. Which measure by the nurse is most likely to minimize this sensation and promote relaxation?

Correct answer: D

Rationale: Allowing the child to place their hand over the nurse's hand helps reduce the tickling sensation and increases the child's comfort during the examination.

5. A toddler’s mother calls the nurse because she thinks her son has swallowed a button type of battery. He has no signs of respiratory distress. The nurse’s response should be based on which premise?

Correct answer: B

Rationale: Radiographic examination is essential to confirm the location of the battery, as it can cause significant damage, particularly if lodged in the esophagus. Immediate surgery may be required depending on its location and the potential for causing harm.
