True True
Question 17
Not yet graded / 5 pts
If someone loses their balance when walking on uneven terrain, explain how tendons and ligaments work to protect the joint and structures within it.
Your Answer:
Tendons connects bones and muscles. Ligaments connect bone to bone. Tendons and ligaments are made up of collagen, a fibrous protein. Molecualr structure of collagen contributes to high tensile strenth. This allows for joint stability in the body.
The tendons and ligaments of joints serve in proprioception (the awareness of ones’ position in space or movement of the body). When these structures undergo stretch or torsional strain, these proprioceptive nerve fibers will cause a reflexive response to adjust the tension on the muscles (to maintain balance and not fall over) that support the joint protecting the capsule and other joint structures.
Question 18
Not yet graded / 5 pts
A patient presents to the ER with severe pain in their right ankle. Blood tests reveal serum uric acid levels of 7.8 mg/dL. They are kept for observation and their 24-hr urine specimen reveals underexcretion of urate. Which phase of gout are they in? What is the goal of your treatment given the phase they are in?
Your Answer:
Patient is in phase 2, acute gout arthritis. Goal is to address the attack and reduce the inflammation. This can be done by using NSAIDs, such as colchicine, or corticosteriods.
This patient is in phase 2 of gout or acute gout arthritis. The goal of treatment is to manage symptoms and terminate the acute attack primarily through NSAIDS.
Question 19
Not yet graded / 5 pts
Which of the following patients is at greater risk for developing osteoporosis and sustaining a fracture? Explain how you came to your conclusion. Patient A. is a 75-year-old white Caucasian male who has a history of a distal radius fractures at age 65. Patient B. is a 60- year-old African American female who is postmenopausal. She is active and does not have a history of fractures.
Your Answer:
Patient A.
The patient is a white male over the age of 70. He has a previous history of bone fractures.
Patient A is at higher risk. Even though he is a male, he is advanced in age, white Caucasian, and sustained a fracture after the age of 50. Patient B is a postmenopausal female; however, she is active and of African American decent which is associated with high BMD and low rates of fracture.
Question 20
Not yet graded / 5 pts
A 40-year-old patient sustains an incomplete spinal cord injury affecting their ability to walk. They primarily use a wheel chair to complete daily activities. Explain why this patient is at increased risk for developing OA in their lower extremities.
Your Answer:
Males have a higher risk of developening OA. Immobility is a risk factor for developing OA. It compromises the lubrication of the joint. This can lead to structural changes.
Immobilization can compromise lubrication of the joint which comes with range of motion and weight bearing. The decreased nourishment of the articular cartilage will eventually lead to the structural joint changes associated with OA.
Question 21
Not yet graded / 5 pts
Compare and contrast the blood supply of cortical bone and cancellous bone. Your Answer:
Cortical bones receive blood supply from nutrient and perforating arteries. Blood is circulated via the central haversion and volkmann canals. Cancellous bones receives blood differently. Instead of receiving blood by vessels, it receives blood via diffusion. It begins at the endoseal surface of the tissue and extends outward through the cancaliculi.
Cortical bone has a direct blood supply. Nutrient and Perforating arteries form an anastomosis (collateral circulation) that circulates through the bone through the Haversian and Volkmann canals. Cancellous bone does not have a direct blood supply. It receives its blood supply through diffusion from the endosteal bone surface extending outward through the canaliculi.
Question 22
Not yet graded / 5 pts
A 22-year-old competitive gymnast has experienced amenorrhea for the past 5 years. Her PCP is suspecting that she may have premature osteoporosis. Would you expect her RANKL levels to be high, normal, or low? Explain why her levels would be at this level.
Your Answer:
WIth 5 years of amenorrhea, this can result in a decline in overall estrogen levels. This will result in high RANKL levels. Estrogen increases the production of OPG, which lowers the rate of osteoclasts. Low levels of estrogen will result in low levels of OPG, which will lead to higher rates of osteoclast activity. Her RANKL levels would be higher than normal. Amenorrhea results in lower estrogen levels.
Estrogen increases the production of OPG which inhibits RANKL. Lower estrogen levels would lead to lower OPG levels in turn increasing RANKL and osteoclast activity.
Question 23
Not yet graded / 10 pts
A 68-year-old, white Caucasian female has a DEXA scan at the recommendation of her PCP. Her scan yielded a T-score of -0.9. Interpret the results of her DEXA scan. Develop a treatment plan giving a pharmacologic recommendation if applicable (be specific with name of supplement and/or class of drug), and a non-pharmacologic recommendation.
Your Answer:
T-score of -1.0 and above are considerd normal bone density. This patient is borderline, so its important that the patient take regular and adequate calcium, as well as incorporate weight bearing excercises.
Recommended for postmenapausal women is 1500mg of calcium. This can be consumed via diet or supplements. Vitamin D supplements, between 400 and 800IUs, should be consumed as well. Vitamin D increases calcium absroption.
This T-score indicates normal bone density; however, because of this patient’s age, race, and gender, she should take a Calcium supplement as well as a Vitamin D supplement. She should also be participating in regular weight bearing activities such as walking or even resistance exercise.
Question 24
Not yet graded / 10 pts
A 72-year-old male is said to be in phase 3 of gout. He is obese and has a history of alcohol abuse. Develop a treatment plan including specific pharmacologic intervention and a non-pharmacologic recommendation to manage his disease.
Your Answer:
During this inter-critical phase, preventing future attacks is key. Its important to get the uric acid levels under control. Allopurinol or a uricosuric drug can be used to reduce the uric acid. Lifestyle changes, such as decreasing alcohol consumption, avoiding foods rich in purines (fish, shellfish, bacon), and maintaning a healthy weight, can help in preventing future attacks.
Phase 3 of gout is called inter-critical gout. The patient is asymptomatic, and no joint abnormalities are present. The goal of treatment in this phase is to maintain normal uric acid levels and prevent progression of the disease. Allopurinol is a prescription drug that is used to reduce uric acid levels. This patient should be encouraged to lose weight and decrease his alcohol consumption. He should also avoid purine rich foods such as fish, bacon, and liver. (*Note – the student has to provide 1 pharmacologic intervention and 1 non-pharmacologic recommendation.)
Question 25
Not yet graded / 10 pts
A patient has a bilateral presentation of pain in the PIP joints of the hands. You believe this pain is due to arthritis but are unsure whether it is a result of RA or OA. What are 3 questions you could ask this patient to help you differentiate between RA and OA?
Your Answer:
1) Is this more of an acute pain or has been going on for sometime?
2) Do you experience morning stiffness, which resolves in less than 30min or does the pain linger past 30min?
3) Do you feel more pain during activity or does the pain resolve during activity?
1. Do you experience stiffness in the morning? 2. If so, does it last less than or longer than 30 minutes? 3. Does prolonged movement aggravate or alleviate your symptoms? 4. Do you ever have periods of relief, or do you experience pain daily? 5. Did your pain start in both hands or did it start with one hand and develop in the other over time? 6. What is your profession? (occupations requiring repetitive movements often lead to OA) *Note – student only has to provide 3 questions. [Show Less]
