1. Which parameter correlates best with measurements of total muscle mass?

• A. Height
• B. Weight
• C. Skinfold thickness
• D. Upper arm circumference

Correct answer: D

Rationale: Upper arm circumference correlates best with total muscle mass because it includes both muscle and fat components, making it a reliable indicator of muscle mass.

2. What is the most critical physiological change required of newborns at birth?

• A. Transition from fetal to neonatal breathing
• B. Body temperature maintenance
• C. Stabilization of fluid and electrolytes
• D. Closure of fetal shunts in the heart

Correct answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The most critical physiological change required of newborns at birth is the initiation of breathing. This transition is crucial for the newborn to start exchanging oxygen and carbon dioxide outside the womb, marking the beginning of their independent respiratory function. Choices B, C, and D are important aspects of newborn care but are not as immediately critical as the establishment of breathing for oxygenation and removal of carbon dioxide, which is essential for the newborn's survival and adaptation to extrauterine life.

3. A preschool-age boy presents to the outpatient clinic for a sore throat. In the child’s mind, which is the most likely cause for the sore throat?

• A. Being exposed to a classmate with strep throat
• B. Not eating the right foods
• C. Not taking daily vitamins
• D. Yelling at sibling for being annoying

Correct answer: D

Rationale: The correct answer is D. Preschool-age children often attribute illness to their actions, like yelling at a sibling or not following instructions. They may not understand medical causes such as exposure to infections like strep throat (choice A), dietary factors (choice B), or vitamin deficiencies (choice C). It is common for young children to connect symptoms to recent behaviors or events within their limited understanding.

4. Kimberly is having a checkup before starting kindergarten. The nurse asks her to do the “finger-to-nose test.” What is the purpose of this test?

• A. Deep tendon reflexes
• B. Cerebellar function
• C. Sensory discrimination
• D. Ability to follow directions

Correct answer: B

Rationale: The finger-to-nose test assesses cerebellar function, which is responsible for balance and coordination. The test evaluates how well the cerebellum controls motor functions and coordination. Choice A, deep tendon reflexes, is incorrect because this test does not assess reflexes but rather cerebellar function. Choice C, sensory discrimination, is incorrect as this test focuses on motor function rather than sensory abilities. Choice D, ability to follow directions, is incorrect since the test primarily assesses motor coordination and not cognitive skills related to following instructions.

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

• A. Administer antibiotics immediately
• B. Perform a lumbar puncture
• C. Isolate the child
• D. Obtain a complete blood count

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.
