Chief Complaint: 74-year-old woman with shortness of breath and swelling. History: Martha Wilmington, a 74-year-old woman with a history of rheumatic fever while in her twenties, presented to her physician with complaints of increasing shortness of breath ("dyspnea") upon exertion. She also noted that the typical swelling she's had in her ankles for years has started to get worse over the past two months, making it especially difficult to get her shoes on toward the end of the day. In the past week, she's had a decreased appetite, some nausea and vomiting, and tenderness in the right upper quadrant of the abdomen. On physical examination, Martha's jugular veins were noticeably distended. Auscultation of the heart revealed a low-pitched, rumbling systolic murmur, heard best over the left upper sternal border. In addition, she had an extra, "S3" heart sound. 9. What is the general term describing Martha's condition? 10. How might Martha's body compensate for the above condition? 11. Martha is started on a medication called digoxin. Why was she given this medication, and how does it work?

Question:

Two weeks after starting digoxin, Martha returns to the physician's office for a follow-up visit. On physical examination, she still has significant hepatomegaly and pitting edema, and is significantly hypertensive (i.e. she has high blood pressure). Her physician prescribes a diuretic called furosemide (or "Lasix"). Why was she given this????

Thanks

Chief Complaint: 8-year-old girl with excessive thirst, frequent urination, and weight loss.

History: Cindy Mallon, an 8-year-old girl in previously good health, has noticed that, in the past month, she is increasingly thirsty. She gets up several times a night to urinate, and finds herself gulping down glassfuls of water. At the dinner table, she seems to be eating twice as much as she used to, yet she has lost 5 pounds in the past month. In the past three days, she has become nauseated, vomiting on three occasions, prompting a visit to her pediatrician.

Questions

1. At the doctor's office, blood and urine samples are taken. The following lab results are noted:

blood glucose level = 545 mg/dl
blood pH level = 7.23

(normal = 50 - 170 mg/dl)
(normal = 7.35 - 7.45)

urine = tested positive for glucose and for acetone / acetoacetate (i.e. ketone bodies) (normally urine is free of glucose and ketone bodies)

Question 1: How will the urinary system attempt to rectify Cindy’s decreased blood pH? Be specific.

In her mid-forties, Cindy began to show early signs of diabetic nephropathy (kidney disease), consisting of persistent proteinuria, hypertension, and gradually decreasing renal function as measured by chemical tests. She nonetheless felt fairly healthy over the next 10 years. At age 55, however, she has noticed becoming increasingly fatigued upon mild physical exertion and requiring more sleep than previously. In addition, she has generally felt nauseated most of the time, and in the past two weeks, has vomited on several occasions. She has increased swelling in her ankles, and is short of breath. She has also become less responsive over the past day or so. Laboratory tests reveal that her kidney disease is now progressing at a much faster rate:

BUN (blood urea nitrogen) = 56 mg / dl         (normal = 10 - 20 mg / dl)
Urinary output = 25 cc / hour                         (normal = 50-60 cc / hour)

Cindy is advised by her physician that her kidneys are failing. She is informed about treatment options: hemodialysis vs. continuous ambulatory peritoneal dialysis (CAPD) vs. kidney transplant. In consultation with her physician, Cindy chooses to undergo hemodialysis. A checkup two weeks after beginning dialysis reveals the BUN has decreased to 35 mg / dl. Although hemodialysis is fairly effective, it is not fool-proof. For example, patients with chronic renal failure, despite a regular schedule of hemodialysis, will experience disruptions in calcium and phosphate balance.

Question 2: How might the endocrine system compensate for the change in blood calcium levels?
