Nursing Elites

1. 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.

2. The nurse is caring for a child with acute postinfectious glomerulonephritis. Which of the following best describes the pathophysiology of acute postinfectious glomerulonephritis?

• A. Occurs after a urinary tract infection
• B. Occurs after a streptococcal infection
• C. Associated with renal vascular disorders
• D. Is caused by E. coli

Correct answer: B

Rationale: The correct answer is B: 'Occurs after a streptococcal infection.' Acute postinfectious glomerulonephritis often occurs after an infection with certain strains of streptococcus bacteria, specifically group A streptococcus. The body’s immune response to the infection leads to inflammation and damage in the kidneys. Choices A, C, and D are incorrect because acute postinfectious glomerulonephritis is primarily associated with streptococcal infections, not urinary tract infections, renal vascular disorders, or E. coli.

3. The clinic nurse is instructing parents about caring for a toddler with ascariasis (common roundworm). Which statement made by the parents indicates a need for further teaching?

• A. We will wash our hands often, especially after diaper changes
• B. We know that roundworm can be transmitted from person to person
• C. We will be sure to continue the nitazoxanide (Alinia) orally for 3 days
• D. We will bring a stool sample to the clinic for examination in 2 weeks

Correct answer: B

Rationale: Roundworm (ascariasis) is typically transmitted through ingestion of contaminated soil, not directly from person to person. This statement indicates a misunderstanding requiring clarification.

4. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

5. What condition is the most common cause of acute renal failure in children?

• A. Pyelonephritis
• B. Tubular destruction
• C. Severe dehydration
• D. Upper tract obstruction

Correct answer: C

Rationale: Severe dehydration is the most common cause of acute renal failure in children, as it leads to prerenal azotemia, which can progress to renal failure if not corrected. Other causes like pyelonephritis and tubular destruction are less common and usually secondary to other conditions.
