1. By what age does birth weight usually triple?

• A. 1 year
• B. 1 month
• C. 2 years
• D. 6 months

Correct answer: A

Rationale: The correct answer is A: 1 year. By the age of 1 year, a baby’s birth weight typically triples. This period allows for significant growth and development in infants. Choices B, C, and D are incorrect because birth weight does not usually triple by 1 month, 2 years, or 6 months of age, respectively.

2. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

3. What is the appropriate method for measuring the temperature of a 2-day-old neonate?

• A. Tympanic
• B. Oral
• C. Axillary
• D. Rectal

Correct answer: C

Rationale: For a 2-day-old neonate, the most suitable method to measure temperature is the axillary method. This approach is considered safe and appropriate for neonates, minimizing the risk of injury. Tympanic temperature measurement may not be as accurate in neonates due to their small ear canals. Oral temperature measurement is not recommended for neonates as they may not be able to hold a thermometer properly in their mouths. Rectal temperature measurement is invasive and carries a higher risk of injury and should be avoided unless absolutely necessary.

4. An infant is brought to the emergency department with the following clinical manifestations: poor skin turgor, weight loss, lethargy, tachycardia, and tachypnea. This is suggestive of which situation?

• A. Water excess
• B. Sodium excess
• C. Water depletion
• D. Potassium excess

Correct answer: C

Rationale: These symptoms are indicative of dehydration or water depletion, which is common in infants and can rapidly lead to severe consequences if not addressed promptly.

5. The nurse is assessing a child's capillary refill time. This can be accomplished by doing what?

• A. Inspect the chest
• B. Auscultate the heart
• C. Palpate the apical pulse
• D. Palpate the nail bed with pressure to produce a slight blanching

Correct answer: D

Rationale: Capillary refill time is assessed by applying pressure to the nail bed and observing how quickly the color returns, indicating peripheral circulation status.
