Question 1 of 5
A professional tennis player comes into the clinic complaining of a sore elbow. The nurse will assess for tenderness at the:
Correct Answer: D
Rationale: The correct answer is D, medial and lateral epicondyle. This is because tennis elbow, or lateral epicondylitis, is a common condition in tennis players characterized by pain and tenderness at the lateral epicondyle. Assessing for tenderness at the medial and lateral epicondyle helps to confirm the diagnosis. Choice A, olecranon bursa, is not typically associated with tennis elbow. Choice B, annular ligament, is more related to the stability of the radial head. Choice C, base of the radius, is not a common site of tenderness in tennis elbow.
Question 2 of 5
The nurse is examining a 6-month-old infant and places the infant's feet flat on the table and flexes his knees up. The nurse notes that the right knee is significantly lower than the left. Which of these statements is true of this finding?
Correct Answer: A
Rationale: The correct answer is A. A positive Allis sign in an infant indicates hip dislocation. When one knee is significantly lower than the other during the Ortolani-Barlow maneuver, it suggests hip dysplasia or dislocation. This finding requires further evaluation and intervention. Choice B is incorrect because a dislocated patella does not present with this specific sign. Choice C is incorrect as a negative Allis sign is actually normal and symmetric in infants. Choice D is incorrect because immediate evaluation and management are needed for a positive Allis sign, not waiting for 2 weeks.
Question 3 of 5
The two parts of the nervous system are the:
Correct Answer: B
Rationale: The correct answer is B: Central and peripheral. The central nervous system consists of the brain and spinal cord, responsible for processing information and generating responses. The peripheral nervous system includes all nerves outside the central nervous system, connecting the CNS to the rest of the body. Motor and sensory (choice A) are functions within the nervous system, not separate parts. Peripheral and autonomic (choice C) are both divisions of the peripheral nervous system, not the two main parts. Hypothalamus and cerebral (choice D) are specific structures within the brain, not the two main parts of the nervous system.
Question 4 of 5
Which of these statements about the peripheral nervous system is correct?
Correct Answer: D
Rationale: Rationale for Correct Answer (D): 1. "The peripheral nerves carry input to the central nervous system by afferent fibers and away from the central nervous system by efferent fibers." - This statement correctly describes the functions of afferent and efferent fibers in the peripheral nervous system. - Afferent fibers transmit sensory information from the peripheral organs to the central nervous system. - Efferent fibers transmit motor commands from the central nervous system to the peripheral organs. Summary of Incorrect Choices: A: "The CNs enter the brain through the spinal cord." - Incorrect because cranial nerves (CNs) directly connect to the brain, bypassing the spinal cord. B: "Efferent fibers carry sensory input to the central nervous system through the spinal cord." - Incorrect because efferent fibers carry motor commands away from the central nervous system, not sensory input towards it. C: "The peripheral nerves are inside the central nervous system and carry impulses through their motor fibers
Question 5 of 5
While obtaining a health history of a 3-month-old infant from the mother, the nurse asks about the infant's ability to suck and grasp the mother's finger. What is the nurse assessing?
Correct Answer: A
Rationale: The correct answer is A: Reflexes. At 3 months, infants have primitive reflexes such as sucking and grasping, controlled by the brainstem and spinal cord. The nurse is assessing the infant's normal neurological development. Choice B, intelligence, is not appropriate to assess in a 3-month-old. Choice C, CNs (cranial nerves), is too specific for this assessment. Choice D, cerebral cortex function, is not fully developed at this age to control sucking and grasping.
