Women’s and Men’s Health, Infections, and Hematologic Disorders

 

Case study

A 14-year-old female is brought to the urgent care by her mother, who states that the girl has had an abnormal number of bruises and “funny looking red splotches” on her legs. These bruises were first noticed about 2 weeks ago and are not related to trauma. PMH not remarkable and she takes no medications. The mother does state the girl is recovering from a “bad case of mono” and was on bedrest at home for the past 3 weeks. The girl noticed that her gums were slightly bleeding when she brushed her teeth that morning.

Labs at urgent care demonstrated normal hgb and hct with normal WBC differential. Platelet count of 100,000/mm3 was the only abnormal finding. The staff also noticed that the venipuncture site oozed for a few minutes after pressure was released. The doctor at urgent care referred the patient and her mother to the ED for a complete work-up of the low platelet count, including a peripheral blood smear for suspected immune thrombocytopenia purpura.

 

Assignment (2- to 3-page case study analysis)

In your Case Study Analysis related to the scenario provided, explain the following:

· The factors that affect fertility (STDs).

· Why inflammatory markers rise in STD/PID.

· Why prostatitis and infection happens. Also explain the causes of systemic reaction.

· Why a patient would need a splenectomy after a diagnosis of ITP.

· Anemia and the different kinds of anemia (i.e., micro and macrocytic).

Pathophysiology

/in /by

ssignment:

  1. Complete the weekly Discussion questions requirement.
  2. In a 1000-word APA essay – Complete all three of the following SherPath case studies: 1. Edema, 2. Pernicious Anemia, 3. Cardiovascular System – Atherosclerosis.

Case Study

Fluid and Electrolytes

Case Study: Edema

approx 30 min

Ms. Rand is a 65-year-old woman who spends most of her day sitting on her porch and recovering from a recent surgery involving the removal of suspected cancerous lymph glands in the inguinal area. She is now complaining that her shoes are fitting too tightly, and she has developed poorly healing sores on her legs and ankles. A closer examination also shows distention in her varicose veins. Blood tests reveal a low level of proteins in the plasma.

Question 1

Based on the patient history and the signs and symptoms, identify the fluid imbalance the patient is experiencing, and state the rationale for your answer.

Answers may vary.

Question 2

Discuss the four general causes of edema and how they apply in the case of this patient.

Answers may vary.

Question 3

Discuss the swelling, sores, varicose vein distention, and other effects that edema can have on a patient.

Case Study

Hematologic System

Case Study: Pernicious Anemia

approx 30 min

Mr. Alvis, age 57, presented to his physician with marked fatigue, nausea with occasional diarrhea, and a sore, swollen tongue. Lately he also has been experiencing a tingling feeling in his toes and a feeling of clumsiness. Microscopic examination of a blood sample indicated a reduced number of erythrocytes, many of which are megaloblasts, and a reduced number of leukocytes, including many large, hypersegmented cells. Hemoglobin and serum levels of vitamin B12 were below normal. Additional tests confirm pernicious anemia.

Question 1

Relate the pathophysiology of pernicious anemia to the manifestations listed above.

Answers may vary.

Question 2

Discuss how the gastric abnormalities contribute to vitamin B12 and iron deficiency and how vitamin B12 deficiency causes complications associated with pernicious anemia.

Answers may vary.

Question 3

Discuss other tests that could be performed to diagnose this type of anemia.

Answers may vary.

Question 4

Discuss the treatment available and the limitations.

Case Study

Cardiovascular System

Case Study: Cardiovascular System – Atherosclerosis

approx 30 min

Mr. Kelly is a 57-year-old man who consulted his physician after noticing marked leg pains while playing golf. He had previously noticed increasing fatigue and discomfort in his legs associated with moderate exercise. When sitting for extended periods with legs dangling, his legs became red, and sometimes his feet felt numb. His history indicates he smokes cigarettes and is chronically overweight. His blood cholesterol and other lipid levels are abnormal, and his physician suspects peripheral atherosclerosis as the cause of his discomfort.

Question 1

Discuss the development of atherosclerosis, including the predisposing factors in this case and the pathophysiological changes.

Answers may vary.

Question 2

Discuss the complications that might develop in this patient.

Answers may vary.

Question 3

Discuss the treatments for all aspects of the patient’s condition, including slowing the progress of the atherosclerosis, maintaining circulation in the leg, and treating complications.
