NURS 6501 Concepts of Neurological and Musculoskeletal Disorders – Part 1
NURS 6501 Concepts of Neurological and Musculoskeletal Disorders – Part 1
It is no coincidence that the neurological system and the musculoskeletal system share both anatomical, physiological, and functional connectivity. This structure-function relationship between the neuronal and muscular topology is responsible for influencing the disease process, the pathogenesis, presentation, diagnostic formulation, and treatment of both systems. Therefore, an understanding of the symptoms of alterations in neurological and musculoskeletal systems is a critical step in diagnosis and treatment and helps in educating the affected patients. This paper provides an account of the interplay between the neurological and the musculoskeletal system, how the racial and ethnic variables impact the physiological functioning, and how these processes interact to affect the patient.
Pathophysiologic processes that would account for the patient presenting these symptoms
Conspicuously, the patient has a history of hypertension and smoking that form the basis of his clinical symptoms including left-sided weakness of both the upper and lower limbs and a mild left facial droop. These features suggest a stroke. Hypertension is a well-established cause of stroke through various mechanisms that include acceleration of the arteriosclerotic process in the cerebral arteries thus increasing the risk of stenosis, embolism, and consequently infarction. Furthermore, high intravascular pressure within the cerebral arteries leads to considerable damage to the endothelial lining and alteration of the smooth muscle function (Wajngarten & Silva, 2019). This endothelial damage and altered blood cell-endothelium interaction lead to the formation of local thrombi, ischemia, and cerebral infarction whereas smooth muscle cell degeneration leads to intracerebral hemorrhages.
Smoking on the other hand is associated with an increased risk of developing a stroke. According to Pan et al. (2019) smokers have an increased risk of overall stroke compared with nonsmokers, with a pooled odds ratio of 1.61 (95% CI: 1.34–1.93). Tobacco smoke contains a lot of chemicals that include nicotine, carbon monoxide, and cyanide among many others. These chemicals increase the risk of developing atherosclerosis, platelet aggregation, hypertension, low levels of high-density cholesterol, and high levels of low-density cholesterol. A complex and multifactorial interaction of the abovementioned factors leads to impaired vascular function resulting in both cardiovascular compromise and cerebral embolism and infarction.
Racial/ethnic variables that may impact physiological functioning
Generally, evidence shows that a racial disparity exists in the presentation of this physiological process, affecting more blacks as compared to whites. According to a study by Howard et al. (2019), the black individuals aged between 45 and 64 years had a 3-fold increase of developing stroke as compared with the whites. Black individuals have a higher preponderance of stroke because of their high risk to develop metabolic conditions such as diabetes mellitus, hypertension, obesity, hypercholesterolemia, and smoking (Tong et al., 2021).
How these processes interact to affect the patient
Neurological and musculoskeletal processes work hand in hand. Every movement the body makes requires communication between the brain and the muscles. Consequently, a pathologic process affecting the neurological process can lead to musculoskeletal manifestations such as hemiplegia, muscle spasms, muscle atrophy, and muscle pain among others. For instance, chronic musculoskeletal pain is principally considered a nervous system disorder as a result of nervous system plasticity (George & Bishop, 2018). Similarly, several factors such as smoking, hypertension, aging, and racial variables impact these physiologic systems resulting in an inherent complexity of interactions that affect patient functioning.
Conclusion
Musculoskeletal and neurological systems are correlated. Nurses must assess both systems at a given point for effective diagnosis and treatment. It is also elemental to educate the patient concerning modifiable risk factors such as smoking and hypertension that result in occurrences that limit the functioning of the musculoskeletal and neurological systems.

Question 2
4 out of 4 points
Scenario 1: GoutA 68-year-old obese male presents to the clinic with a 3-day history of fever with chills, and Lt. great toe pain that has gotten progressively worse. Patient states this is the first time that this has happened, and nothing has made it better and walking on his right foot makes it worse. He has tried acetaminophen, but it did not help. He took several ibuprofen tablets last night which did give him a bit of relief. HPI: hypertension treated with Lisinopril/HCTZ . SH: Denies smoking. Drinking: “a fair amount of red wine” every week. General appearance: Ill appearing male who sits with his right foot elevated. PE: remarkable for a temp of 100.2, pulse 106, respirations 20 and BP 158/92. Right great toe (first metatarsal phalangeal [MTP]) noticeably swollen and red. Unable to palpate to assess range of motion due to extreme pain. CBC and Complete metabolic profile revealed WBC 15,000 mm3 and uric acid 9.0 mg/dl. Diagnoses the patient with acute gout. Question:Explain why a patient with gout is more likely to develop renal calculi. |

Week 7: Concepts of Neurological and Musculoskeletal Disorders – Part 1
Anatomists often use the analogy of a house to explain the human body, with skeletal systems, respiratory systems, and circulatory systems represented as a home’s framing structure, ventilation, and piping, respectively. Such analogies further emphasize the point that relationships between systems can result in complications when issues arise in one system.
With hundreds of diseases that can impact the brain, spine, and nerves, neurological disorders represent a complicated array of issues
that present significant health concerns. Disorders such as strokes and Parkinson’s disease not only affect the nervous system, however; they can have secondary impacts in other areas, especially the musculoskeletal system.
This week, you examine fundamental concepts of neurological disorders. You explore common disorders that impact these systems and you apply the key terms and concepts that help communicate the pathophysiological nature of these issues to patients.

Question 16
Needs Grading
A 22-year-old male is in the Surgical Intensive Care Unit (SICU) following a motor vehicle crash (MVC) where he sustained multiple life-threatening injuries including a torn aorta, ruptured spleen, and bilateral femur fractures. He has had difficulty maintaining his mean arterial pressure (MAP) and has required various vasopressors. He has a triple lumen central venous catheter (CVC) for monitoring his central venous pressure, administration of medications and blood products, as well as total parenteral nutrition. Per hospital protocol, he is receiving an unfractionated heparin 1:1000 flush after administration of each of the triple antibiotics that have been ordered to maintain patency of the lumens. Seven days post injury, the APRN in the SICU is reviewing the patient’s morning labs and notes that his platelet count has dropped precipitously to 50,000 /mm3 from 148,000/mm3 two days ago. The APRN suspects the patient is developing heparin induced thrombocytopenia (HIT).

Question 2 of 2:
The APRN assesses the patient and notes there is a decreased right posterior tibial pulse with cyanosis of the entire foot. The APRN recognizes this probably represents arterial thrombus formation. How does someone who is receiving heparin develop arterial and venous thrombosis? |
