Question 1 of 5
The patellar tendon reflex assesses which nerve root?
Correct Answer: B
Rationale: The patellar tendon reflex is mediated by the femoral nerve, which receives sensory input from the L4 nerve root. When the patellar tendon is tapped, the sensory information is transmitted via the L4 nerve root to the spinal cord, activating the motor response through the femoral nerve. Therefore, the correct answer is B: L4. A: L1 - Incorrect. The L1 nerve root does not innervate the patellar tendon reflex. C: L5 - Incorrect. The L5 nerve root does not play a direct role in the patellar tendon reflex. D: S1 - Incorrect. The S1 nerve root is not involved in the patellar tendon reflex pathway.
Question 2 of 5
The Q angle is increased by which of the following?
Correct Answer: D
Rationale: The Q angle is the angle between the line of pull of the quadriceps muscle and the patellar tendon. Tight lateral retinaculum can pull the patella laterally, increasing the Q angle. Genu varum (A) and decreased femoral anteversion (B) would actually decrease the Q angle as they align the patella more centrally. Internal tibial torsion (C) might alter the patellar tracking but would not directly increase the Q angle. Therefore, the correct answer is D.
Question 3 of 5
All of the following muscles involved in wrist and finger extension receive innervation from the radial nerve except:
Correct Answer: C
Rationale: The correct answer is C: Extensor digiti minimi. The extensor digiti minimi muscle is innervated by the posterior interosseous nerve, a branch of the radial nerve. The other muscles listed (A, B, D) are all involved in wrist and finger extension and receive innervation from the radial nerve directly. Therefore, extensor digiti minimi is the exception as it is not innervated by the radial nerve, unlike the other muscles mentioned.
Question 4 of 5
The nurse is reviewing information about evidence-based practice (EBP). Which statement best reflects EBP?
Correct Answer: C
Rationale: The correct answer is C because evidence-based practice (EBP) emphasizes the integration of best available evidence with clinician expertise and patient preferences. This approach ensures that clinical decisions are informed by the most current and relevant evidence, while also considering the individual needs and values of the patient. Choice A is incorrect because EBP does not rely solely on tradition but on empirical evidence. Choice B is incorrect as it oversimplifies EBP as just using best practice techniques without considering the broader context. Choice D is incorrect because patient preferences play a crucial role in EBP to provide patient-centered care.
Question 5 of 5
When reviewing the concepts of health, the nurse recalls that the components of holistic health include which of these?
Correct Answer: D
Rationale: The correct answer is D because holistic health emphasizes the interconnectedness of the mind, body, and spirit, viewing them as interdependent aspects of an individual's overall well-being. This approach recognizes that all three components must be in balance for optimal health. Choice A is incorrect because disease can also originate internally. Choice B is incorrect as humans are influenced by their environment. Choice C is incorrect as multiple healthcare professionals contribute to a patient's health state, not just nurses.
