                                          Disorders of the Veins and Arteries

Advanced practice nurses often treat patients with vein and artery disorders such as chronic venous insufficiency (CVI) and deep venous thrombosis (DVT). While the symptoms of both disorders are noticeable, these symptoms are sometimes mistaken for signs of other conditions, making the disorders difficult to diagnose. Nurses must examine all symptoms and rule out other potential disorders before diagnosing and prescribing treatment for patients. In this Assignment, you explore the epidemiology, pathophysiology, and clinical presentation of CVI and DVT.

To Prepare

· Review the section “Diseases of the Veins” (pp. 598-599) in Chapter 23 of the Huether and McCance text. Identify the pathophysiology of chronic venous insufficiency and deep venous thrombosis. Consider the similarities and differences between these disorders.

· Select a patient factor different from the one you selected in this week’s Discussion: genetics, gender, ethnicity, age, or behavior. Think about how the factor you selected might impact the pathophysiology of CVI and DVT. Reflect on how you would diagnose and prescribe treatment of these disorders for a patient based on the factor you selected.

· Review the “Mind Maps—Dementia, Endocarditis, and Gastro-oesophageal Reflux Disease (GERD)” media in the Week 2 Learning Resources. Use the examples in the media as a guide to construct two mind maps—one for chronic venous insufficiency and one for venous thrombosis. Consider the epidemiology and clinical presentation of both chronic venous insufficiency and deep venous thrombosis.

To Complete

Write a 2- to 3-page paper that addresses the following:

· Compare the pathophysiology of chronic venous insufficiency and deep venous thrombosis. Describe how venous thrombosis is different from arterial thrombosis.

· Explain how the patient factor you selected might impact the pathophysiology of CVI and DVT. Describe how you would diagnose and prescribe treatment of these disorders for a patient based on the factor you selected.

· Construct two mind maps—one for chronic venous insufficiency and one for deep venous thrombosis. Include the epidemiology, pathophysiology, and clinical presentation, as well as the diagnosis and treatment you explained in your paper.

Assignment: Adaptive Response

As an advanced practice nurse, you will examine patients presenting with a variety of disorders. You must, therefore, understand how the body normally functions so that you can identify when it is reacting to changes. Often, when changes occur in body systems, the body reacts with compensatory mechanisms. These compensatory mechanisms, such as adaptive responses, might be signs and symptoms of alterations or underlying disorders. In the clinical setting, you use these responses, along with other patient factors, to lead you to a diagnosis.

Consider the following scenarios:

Scenario 1:

Jennifer is a 2-year-old female who presents with her mother. Mom is concerned because Jennifer has been “running a temperature” for the last 3 days. Mom says that Jennifer is usually healthy and has no significant medical history. She was in her usual state of good health until 3 days ago when she started to get fussy, would not eat her breakfast, and would not sit still for her favorite television cartoon. Since then she has had a fever off and on, anywhere between 101oF and today’s high of 103.2oF. Mom has been giving her ibuprofen, but when the fever went up to 103.2oF today, she felt that she should come in for evaluation. A physical examination reveals a height and weight appropriate 2-year-old female who appears acutely unwell.  Her skin is hot and dry. The tympanic membranes are slightly reddened on the periphery, but otherwise normal in appearance. The throat is erythematous with 4+ tonsils and diffuse exudates. Anterior cervical nodes are readily palpable and clearly tender to touch on the left side. The child indicates that her throat hurts “a lot” and it is painful to swallow. Vital signs reveal a temperature of 102.8oF, a pulse of 128 beats per minute, and a respiratory rate of 24 beats per minute.

Scenario 2:

Jack is a 27-year-old male who presents with redness and irritation of his hands. He reports that he has never had a problem like this before, but about 2 weeks ago he noticed that both his hands seemed to be really red and flaky. He denies any discomfort, stating that sometimes they feel “a little bit hot,” but otherwise they feel fine. He does not understand why they are so red. His wife told him that he might have an allergy and he should get some steroid cream. Jack has no known allergies and no significant medical history except for recurrent ear infections as a child. He denies any traumatic injury or known exposure to irritants. He is a maintenance engineer in a newspaper building and admits that he often works with abrasive solvents and chemicals. Normally he wears protective gloves, but lately they seem to be in short supply so sometimes he does not use them. He has exposed his hands to some of these cleaning fluids, but says that it never hurt and he always washed his hands when he was finished.

Scenario 3:

Martha is a 65-year-old woman who recently retired from her job as an administrative assistant at a local hospital. Her medical history is significant for hypertension, which has been controlled for years with hydrochlorothiazide. She reports that lately she is having a lot of trouble sleeping, she occasionally feels like she has a “racing heartbeat,” and she is losing her appetite. She emphasizes that she is not hungry like she used to be. The only significant change that has occurred lately in her life is that her 87-year-old mother moved into her home a few years ago. Mom had always been healthy, but she fell down a flight of stairs and broke her hip. Her recovery was a difficult one, as she has lost a lot of mobility and independence and needs to rely on her daughter for assistance with activities of daily living. Martha says it is not the retirement she dreamed about, but she is an only child and is happy to care for her mother. Mom wakes up early in the morning, likes to bathe every day, and has always eaten 5 small meals daily. Martha has to put a lot of time into caring for her mother, so it is almost a “blessing” that Martha is sleeping and eating less. She is worried about her own health though and wants to know why, at her age, she suddenly needs less sleep.

To Prepare

• Review the three scenarios, as well as Chapter 6 in the Huether and McCance text.
• Identify the  pathophysiology of the disorders presented in each of the three scenarios, including their  associated alterations. Consider the adaptive responses to the alterations.
• Review the examples of  “Mind Maps—Dementia, Endocarditis, and Gastro-oesophageal Reflux Disease  (GERD)” media in this week’s Learning Resources. Then select one of the disorders you identified  from the scenarios. Use the examples in the media as a guide to construct a  mind map for the disorder you selected. Consider the epidemiology, pathophysiology,  risk factors, clinical presentation, and diagnosis of the disorder, as well as  any adaptive responses to alterations.
• Due 12/9/2018 by 12 noon.

Discussion: Disorders of the Reproductive Systems

While the male and female reproductive systems are unique to each sex, they share a common function—reproduction. Disorders of this system range from delayed development to structural and functional abnormalities. Since many reproductive disorders not only result in physiological consequences but also psychological consequences such as embarrassment, guilt, or profound disappointment, patients are often hesitant to seek treatment. Advanced practice nurses need to educate patients on disorders and help relieve associated stigmas. During patient evaluations, patients must feel comfortable answering questions so that you, as a key health care provider, will be able to diagnose and recommend treatment options. As you begin this Discussion, consider reproductive disorders that you would commonly see in the clinical setting.

To Prepare

· Review Chapter 22 and Chapter 23 in the Hammer and McPhee text, as well as Chapter 33 and 34 in the Huether and McCance text.

· Select two disorders of the male and/or female reproductive systems that interest you. Consider the similarities and differences between the disorders.

· Select one of the following factors: genetics, ethnicity, age, or behavior. Think about how the factor you selected might impact the diagnosis of and treatment for the reproductive disorders. 

Post a description of the two reproductive disorders you selected, including their similarities and differences. Then explain how the factor you selected might impact the diagnosis of treatment for the reproductive disorders.
