Nursing Elites

1. Why is the specific gravity for infants lower than for older children?

• A. Infants have a greater body surface area.
• B. Infants have a higher basal metabolic rate.
• C. Infants have a greater percentage of body weight that is water.
• D. Infants' kidneys are less able to concentrate urine.

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. A healthcare professional is planning care for an infant with hyperbilirubinemia receiving phototherapy. Which of the following actions should the healthcare professional include in the plan?

• A. Dress the infant in light, breathable clothing.
• B. Turn and reposition the infant every 4 hours.
• C. Offer the infant frequent, small feedings.
• D. Avoid using lotions on the infant's skin.

Correct answer: B

Rationale: Turning and repositioning the infant every 4 hours is essential to prevent pressure sores and ensure uniform exposure to phototherapy. This practice helps prevent skin breakdown and ensures the effectiveness of the phototherapy in treating hyperbilirubinemia. Dressing the infant in light, breathable clothing (Choice A) is generally a good practice but not directly related to the effectiveness of phototherapy. Offering frequent, small feedings (Choice C) is important for infant nutrition but does not directly impact the phototherapy. Avoiding lotions on the infant's skin (Choice D) is recommended to prevent interference with the phototherapy but is not the most critical action to include in the care plan.

3. A young child admitted to the pediatric unit has fever, irritability, and vomiting with suspected bacterial meningitis. Which cerebrospinal fluid (CSF) result should the nurse anticipate based on these data?

• A. Decreased protein count
• B. Clear, straw-colored fluid
• C. Positive for red blood cells (RBCs)
• D. Decreased glucose level

Correct answer: D

Rationale: In bacterial meningitis, the glucose level in the cerebrospinal fluid (CSF) is typically decreased due to the increased utilization of glucose by the infecting bacteria. This metabolic change leads to a decrease in CSF glucose levels, making choice D the correct answer in this scenario. Choices A, B, and C are incorrect because bacterial meningitis usually results in an increased protein count, cloudy appearance of the CSF due to the presence of bacteria, and absence of red blood cells (RBCs) in the CSF unless there is a traumatic tap, respectively.

4. At what age may an infant close their eyes to bright lights and show improved head control?

• A. 30-33 weeks after conception
• B. 34-36 weeks after conception
• C. Less than 30 weeks after conception
• D. 37-40 weeks after conception

Correct answer: A

Rationale: Around 30-33 weeks after conception, infants usually start closing their eyes in response to bright lights and exhibit enhanced head control. This developmental milestone indicates progress in their visual and motor abilities, reflecting the maturation of their neurological system. As preterm infants continue to grow and develop, they gradually acquire these skills, showcasing the natural progression of their sensory and motor functions.

5. A 4-year-old child is admitted to the hospital secondary to dehydration. Laboratory tests indicate a high hemoglobin and hematocrit, and the serum sodium is below normal levels. Which condition does the nurse suspect based on the current data?

• A. Hypernatremia
• B. Metabolic acidosis
• C. Hypotonic dehydration
• D. Isotonic dehydration

Correct answer: C

Rationale: The correct answer is hypotonic dehydration. The combination of high hemoglobin and hematocrit with low serum sodium indicates hypotonic dehydration. In this condition, there is an excess of solutes relative to water, leading to higher red blood cell concentration (elevated hemoglobin and hematocrit) and low serum sodium levels.
