Nursing Elites

1. A child is admitted with renal failure. Which of these findings should the nurse expect?

• A. Decreased BUN
• B. Azotemia and oliguria
• C. Increased glomerular filtration rate (GFR)
• D. Polyuria and elevated creatinine clearance

Correct answer: B

Rationale: Azotemia (elevated BUN and creatinine) and oliguria (reduced urine output) are classic signs of renal failure, indicating impaired kidney function. In renal failure, the kidneys are unable to effectively filter waste products, leading to an increase in BUN and creatinine levels in the blood. Additionally, oliguria occurs due to decreased kidney function. Increased GFR (Choice C) is not expected in renal failure as it signifies improved kidney function, which is not the case in renal failure. Polyuria and elevated creatinine clearance (Choice D) are not typical findings in renal failure. Polyuria is more commonly associated with conditions like diabetes insipidus, while elevated creatinine clearance would indicate increased kidney function, which is contrary to the impaired function seen in renal failure.

2. What is the primary treatment goal for a child with juvenile idiopathic arthritis?

• A. Pain management
• B. Cure of the disease
• C. Reduction of joint deformity
• D. Physical therapy

Correct answer: A

Rationale: The primary treatment goal for a child with juvenile idiopathic arthritis is pain management. Juvenile idiopathic arthritis is a chronic condition with no known cure, making pain management crucial to improve the quality of life for these children. While reducing joint deformity and physical therapy are important aspects of managing the condition, the primary focus is on alleviating pain and improving function.

3. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

4. Baby M is 5 months old. You notice that she now has the ability to grasp objects between her fingers and opposing thumb. This is known as:

• A. Parachute reflex
• B. Grasp reflex
• C. Pincer grasp
• D. Prehension

Correct answer: C

Rationale: The correct answer is C: Pincer grasp. The pincer grasp is the ability to hold objects between the thumb and another finger, typically developed around 9-12 months. At 5 months, it is early for a pincer grasp to fully develop, but the beginning of this skill can be seen as early as 5 months. Choices A and B are incorrect as the parachute reflex is a protective response to falling and the grasp reflex is an automatic response to touch. Choice D, prehension, is a general term for the act of grasping or holding objects, but it does not specifically refer to holding objects between the thumb and fingers like the pincer grasp does.

5. 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.
