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 preschool-age child is admitted to the hospital with acute postinfectious glomerulonephritis (APIGN). Which is the priority nursing diagnosis for this child?

• A. Risk for Injury related to hypertension.
• B. Altered Growth and Development related to chronic disease.
• C. Risk for Infection related to hypertension.
• D. Fluid Volume Excess related to decreased plasma filtration.

Correct answer: A

Rationale: The priority nursing diagnosis for a preschool-age child with acute postinfectious glomerulonephritis (APIGN) is 'Risk for Injury related to hypertension' due to the potential complications such as hypertensive encephalopathy. Hypertension poses an immediate threat to the child's well-being, making it crucial to address the risk for injury associated with elevated blood pressure as the top priority.

3. 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.

4. Which model of practice emphasizes the child's subjective experience of their abilities?

• A. Occupational Adaptation
• B. Model of Human Occupation
• C. Person-Environment-Occupation-Performance Model
• D. Canadian Model of Occupational Performance and Engagement

Correct answer: B

Rationale: The Model of Human Occupation (MOHO) emphasizes the child's subjective experience of their abilities, focusing on their motivation, roles, habits, and routines. It considers how these factors influence their occupational performance. MOHO helps occupational therapists understand how a child's perceptions of their abilities impact their engagement in meaningful activities and occupations.

5. What is the goal of pharmacologic therapy in the treatment of Parkinson�s disease?

• A. To increase the amount of acetylcholine at the pre-synaptic neurons
• B. To reduce the amount of dopamine available in the substantia nigra
• C. To balance cholinergic and dopaminergic activity in the brain
• D. To block dopamine receptors in pre-synaptic and post-synaptic neurons

Correct answer: C

Rationale: Parkinson�s disease results from a decrease in dopaminergic (inhibitory) activity, leaving an imbalance with too much cholinergic (excitatory) activity. With an increase in dopamine, the neurotransmitter activity becomes more balanced, and symptoms are controlled.
