Question 1 of 5
An imaginary line connecting the highest point on each iliac crest would cross the __________ vertebra.
Correct Answer: B
Rationale: The correct answer is B: Fourth lumbar vertebra. The line connecting the highest points on the iliac crests is called the iliac crest line, which typically crosses the fourth lumbar vertebra. This is a useful landmark for identifying the lumbar vertebrae. The iliac crest is located at the level of the fourth lumbar vertebra, making it the most likely vertebra to be crossed by this line. Choice A (First sacral vertebra) is incorrect because the iliac crest line is above the sacrum. Choice C (Seventh cervical vertebra) is incorrect as it is located much higher in the spine than the iliac crests. Choice D (Twelfth thoracic vertebra) is incorrect as it is located lower in the spine than the iliac crests.
Question 2 of 5
During a neonatal examination, the nurse notices that the newborn infant has six toes. This finding is documented as:
Correct Answer: C
Rationale: The correct answer is C: Polydactyly. Polydactyly refers to the presence of extra digits, such as having six toes. Unidactyly (A) is the absence of one digit, syndactyly (B) is the fusion of digits, and multidactyly (D) is not a recognized term in relation to digit anomalies. Therefore, based on the description of having six toes, polydactyly is the appropriate term to document this finding during the neonatal examination.
Question 3 of 5
A 14-year-old boy who has been diagnosed with Osgood-Schlatter disease reports painful swelling just below the knee for the past 5 months. Which response by the nurse is appropriate?
Correct Answer: C
Rationale: The correct answer is C. Osgood-Schlatter disease is caused by repeated stress on the patellar tendon during periods of rapid growth. It is usually self-limited and resolves with rest. Here is a step-by-step rationale for why this answer is correct: 1. Osgood-Schlatter disease is commonly seen in adolescents during growth spurts. 2. The pain and swelling just below the knee in this 14-year-old boy are typical symptoms of Osgood-Schlatter disease. 3. Rest is the mainstay of treatment for Osgood-Schlatter disease as it allows the inflamed area to heal. 4. The symptoms should improve once the growth spurt is over and the stress on the patellar tendon decreases. 5. Surgery is rarely needed for Osgood-Schlatter disease unless conservative measures fail. In summary, choice C is correct because it addresses the self-limiting nature of Osgood-Schlatter disease and emphasizes the importance of rest
Question 4 of 5
When performing a musculoskeletal assessment, the nurse knows that the correct approach for the examination should be:
Correct Answer: A
Rationale: The correct approach for a musculoskeletal assessment is to examine from proximal to distal. This means starting closer to the body's center and moving towards the extremities. This approach helps to assess for overall strength, range of motion, and joint stability before focusing on specific areas. By starting proximally, the nurse can establish a baseline assessment and then progress methodically to evaluate each joint and muscle group. This systematic approach ensures a comprehensive evaluation of the musculoskeletal system. Summary of Other Choices: B: Distal to proximal - This approach may miss important information about overall strength and stability. C: Posterior to anterior - This sequence is not ideal for a musculoskeletal assessment as it doesn't follow the natural flow of muscle and joint movements. D: Anterior to posterior - This order may not provide a holistic view of the musculoskeletal system and may lead to missing relevant findings.
Question 5 of 5
The ability that humans have to perform very skilled movements such as writing is controlled by the:
Correct Answer: B
Rationale: The correct answer is B: Corticospinal tract. This tract is responsible for carrying signals for voluntary skilled movements from the primary motor cortex to the spinal cord. This includes precise movements like writing. The basal ganglia (A) is involved in motor planning and coordination, not in the direct control of skilled movements. The spinothalamic tract (C) is responsible for transmitting sensory information about pain and temperature, not motor control. The extrapyramidal tract (D) is involved in regulating muscle tone and reflexes, not in executing skilled movements like writing.
