Nursing Elites

1. Which developmental milestone would the nurse expect an 11-month-old infant to have achieved?

• A. Sitting independently
• B. Turning a doorknob
• C. Building a tower of four cubes
• D. Walking independently

Correct answer: A

Rationale: The correct answer is A: Sitting independently. By 11 months, most infants can sit independently. This milestone usually precedes walking, which typically occurs closer to 12 months. Turning a doorknob and building a tower of four cubes involve more complex motor skills that are typically achieved later in development. Therefore, at 11 months, sitting independently is the milestone that the nurse would expect an infant to have achieved.

2. When assessing a child with chronic renal failure, which clinical manifestations would the nurse expect to find?

• A. Uremic frost
• B. Hypotension
• C. Massive hematuria
• D. Severe metabolic acidosis

Correct answer: A

Rationale: When assessing a child with chronic renal failure, the nurse would expect to find uremic frost as a clinical manifestation. Uremic frost, a white powdery deposit of urea on the skin, occurs in severe cases of chronic renal failure due to the accumulation of urea and other waste products in the blood. Hypotension and massive hematuria are less common in chronic renal failure, while severe metabolic acidosis is typically mild to moderate and not a prominent clinical manifestation.

3. Which family theory is described as a series of tasks for the family throughout its life span?

• A. Exchange theory
• B. Developmental theory
• C. Structural-functional theory
• D. Symbolic interactional theory

Correct answer: B

Rationale: Developmental theory outlines the series of tasks and stages that a family goes through over its life span, helping to understand the family's development and needs over time.

4. 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.

5. 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.
