Nursing Elites

1. At what age is binocularity, the ability to fixate on one visual field with both eyes simultaneously, typically achieved?

• A. 1 month
• B. 3 to 4 months
• C. 6 to 8 months
• D. 12 months

Correct answer: B

Rationale: Binocularity, the ability to fixate on one visual field with both eyes simultaneously, is typically achieved by the age of 3 to 4 months. Achieving binocularity at 1 month is too early for most infants as their visual system is still developing. Similarly, 6 to 8 months and 12 months are beyond the normal age range for achieving binocularity, and delayed achievement could indicate potential issues like strabismus, which may lead to visual impairment if not addressed.

2. The nurse is testing an infant's visual acuity. By which age should the infant be able to fix on and follow a target?

• A. 1 month
• B. 1 to 2 months
• C. 3 to 4 months
• D. 6 months

Correct answer: C

Rationale: By 3 to 4 months of age, an infant should be able to fix on and follow a target, indicating proper visual development.

3. 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.

4. Which food should be introduced first to a 6-month-old infant?

• A. Fruits
• B. Eggs
• C. Vegetables
• D. Meat

Correct answer: C

Rationale: Vegetables, particularly pureed ones, are often recommended as a first solid food for infants because they are easy to digest and less likely to cause allergies. Fruits can be introduced later due to their natural sweetness, while eggs and meat are typically introduced after fruits and vegetables as they may pose a higher risk of allergies.

5. What is the primary consideration of susceptibility to infections in neonates?

• A. Increased humoral immunity
• B. Overwhelming anti-inflammatory response
• C. Diminished nonspecific and specific immunity
• D. Excessive levels of immunoglobulin A and immunoglobulin M

Correct answer: C

Rationale: The primary consideration of susceptibility to infections in neonates is their diminished nonspecific and specific immunity. Neonates lack the ability to mount a robust immune response, making them vulnerable to infections. Choice A is incorrect because neonates do not have increased humoral immunity; rather, their humoral immunity is diminished. Choice B is incorrect as neonates do not have an overwhelming anti-inflammatory response; instead, their immune responses are generally weakened. Choice D is incorrect because neonates have diminished or absent levels of immunoglobulin A and immunoglobulin M, contributing to their susceptibility to infections.
