Question 1 of 5
The nurse should use which test to check for large amounts of fluid around the patella?
Correct Answer: A
Rationale: The correct answer is A: Ballottement. This test involves pushing the patella downward and looking for a fluid wave or a "floating" sensation, indicating large amounts of fluid around the patella. The other choices are incorrect because: B: Tinel sign assesses nerve compression; C: Phalen test evaluates for carpal tunnel syndrome; D: McMurray test is used for assessing meniscal injuries in the knee joint.
Question 2 of 5
A mother of a 1-month-old infant asks the nurse why it takes so long for infants to learn to roll over. The nurse knows that the reason for this is:
Correct Answer: B
Rationale: The correct answer is B: Myelin is needed to conduct the impulses, and the neurons of a newborn are not yet myelinated. Myelin is a fatty substance that insulates nerve fibers, allowing for faster and more efficient transmission of nerve impulses. In newborns, the process of myelination is incomplete, which means that the nerve impulses responsible for coordinating the complex movement required for rolling over are slower and less efficient. This delay in myelination is a normal part of infant development and accounts for the time it takes for infants to learn to roll over. Choice A is incorrect because demyelination refers to the loss of myelin, which is not the case in infants. Choice C is incorrect because while the cerebral cortex plays a role in motor function, the lack of myelination in newborns is the primary reason for the delay in rolling over. Choice D is incorrect because the cerebellum is not solely responsible for the movement, and the lack of myelination
Question 3 of 5
During an assessment of the CNs, the nurse finds the following: asymmetry when the patient smiles or frowns, uneven lifting of the eyebrows, sagging of the lower eyelids, and escape of air when the nurse presses against the right puffed cheek. This would indicate dysfunction of which of these CNs?
Correct Answer: B
Rationale: Step-by-step rationale for why the correct answer is B (Motor component of CN VII): 1. The symptoms described indicate facial nerve (CN VII) dysfunction. 2. Asymmetry when smiling/frowning, uneven eyebrow lifting, sagging eyelids are classic signs of CN VII dysfunction. 3. Escape of air when pressing on the cheek suggests weakness of the buccinator muscle innervated by CN VII. 4. CN IV (trochlear nerve) innervates the superior oblique muscle controlling eye movement, not facial expression (eliminate A). 5. CN XI (accessory nerve) innervates sternocleidomastoid and trapezius muscles, not facial muscles (eliminate C). 6. CN X (vagus nerve) controls the larynx and pharynx, while CN VII controls facial muscles (eliminate D). Summary: The correct answer is B because the symptoms align with facial nerve (CN VII) dysfunction, while the other
Question 4 of 5
The nurse places a key in the hand of a patient and he identifies it as a penny. What term would the nurse use to describe this finding?
Correct Answer: B
Rationale: The correct answer is B: Astereognosis. Astereognosis is the inability to recognize objects by touch alone. In this scenario, the patient is unable to correctly identify the key as a key, mistaking it for a penny. This indicates a deficit in tactile object recognition, which is characteristic of astereognosis. A: Extinction refers to the inability to perceive a stimulus on one side when a similar stimulus is presented on the other side simultaneously. This does not apply to the scenario described. C: Graphesthesia is the ability to recognize numbers or letters traced on the skin without visual input. This is not relevant to the patient's inability to identify the key by touch. D: Tactile discrimination involves the ability to differentiate between different textures or shapes using touch. This is not the issue presented in the scenario.
Question 5 of 5
To test for gross motor skill and coordination of a 6-year-old child, which of these techniques would be appropriate? Ask the child to:
Correct Answer: A
Rationale: The correct answer is A: Hop on one foot. This task assesses balance, coordination, and gross motor skills in a 6-year-old child. Hopping on one foot requires a combination of strength, balance, and coordination, making it an appropriate test for gross motor skills. Standing on the head (B) is not developmentally appropriate and poses a risk of injury. Touching finger to nose (C) tests fine motor skills, not gross motor skills. Making 'funny' faces (D) does not assess motor skills or coordination.
