Q

Ascites, what is it and what is it a sign of which chronic disease?

A
  • Is an abnormal accumulation of fluid in peritoneal cavity.
  • Caused by high pressure in the blood vessels of the liver (portal hypertension)
  • Usually severe liver disease, or CHF or pancreatitis.
  • SUPPOSEDLY it can also be caused by chronic renal failure.
    • Cannot eliminate sodium, thus water is retained. Thus, a chronic buildup of fluids and edema

25
Microscopic structure in the kidney that produces urine?
Nephron
26
Primary pathogen that causes gastroenteritis?
* Inflammation of the stomach and intestines accompanied by nausea,vomiting, diarrhea * Norovirus most common, then Salmonella
27
Chronic Renal Failure: what is it?
* Abnormality of the kidneys lasting more than 3 months. (usually years)
28
Other, less common causes for chronic renal failure
Congenital, pyelonephritis (infection of the kidneys from lower UTI usually), OD on ibuprofen, renal calculus, lupus
29
What causes chronic renal failure?
Irreversible loss and damage of a large amount of nephrons. * When the body is losing nephrons, it kicks the remaining ones into overtime, causing hyperfiltration, leading to further loss and kidney damage.
30
Strongest risk factors for chronic renal failure? What are the other causes?
Diabetes and hypertension * Diabetes, hypertension, atherosclerosis, chronic toxins, renal calculi
31
Pathophysiology of chronic renal failure in diabetes
* Excess sugar in blood clogs up nephrons, too much blood gets unfiltered. * Straings nephrons, chronically gets worse. * Kidneys cant filter Na+, K+, water, blood volume. All gets messed up
32
Pathophysiology for chronic renal failure in hypertension
* Causes decreased blood flow to kidneys, altering renin angiotensin system, causing more hypertension. * Too much BP in kidneys, over filtration leading to things getting pushed to urine that the blood needs. Alters blood content and pH. * Become anemic due to no erythropoietin and no RBC creation. * Wastes like urea and nitrogen build up in the blood. (azotemia)
33
Azotemia
Nitrogen in the blood
34
Uremia
Urea build up in the blood
35
5 stages of renal failure
* Stage 1 : No symptoms felt. Hypertension and abnormal urine tests * Stage 2: No symptoms felt. Edema, hypertension, abnormal urine * Stage 3: Fatigue, edema, nocturia, edema * Stage 4: Fatigue, edema, anorexia, dyspnea pruritus, MODS, electrolyte anormalities * Stage 5: Weight loss, dyspnea, AMS, HTN severe, pulmonary edema, acidosis, hyperkalemia
36
Treatment for renal failure
* Cardiac arrests: 1 g IV calcium * Sodium Bicarb later * 12 lead finds hyperkalemia? * Once QRS widens/sine wave, give bicarb, calcium, or albuterol
37
Gastritis symptoms
* Severe abdominal pain, nausea, bloody emesis * Erosion from alcohol, blood oozing from the mucosal lining
38
Does albuterol lessen force of contractions?
yes
39
If unexplained abdominal pain, what should you check?
BGL. Hypoglycemia can present with this.
40
Delivery complications that we cannot deliver in the field
* Placenta previa * Transverse lie * Arm presentation * Prolapsed cord * Cephalopelvic disproportion
41
Post delivery bleeding critical, what do you do?
Fundal massage, then oxytocin, 10 units 1 liter 30 drops/min until it stops (don't give till everything expelled)
42
Changes in the newborn anatomically
* Ligament of Treitz (anchors the small intestine) is formed from the umbilical cord * Foramen ovale (hole between atrias) becomes fossa ovale (sealed up foramen, a depression) * Ductus venosum (oxygenated umbilical cord blood bypasses liver) turns into ligamentum venosum * Ductus arterious (bypasses the lungs by connecting aorta and pulmonary artery) should close.
43
What varies the length of stages of labor?
* Nullipara (no births) vs multipara (multiple births)
44
What are the stages of baby delivery?
* First stage * contractions to 10cm cervix dilation * Can last hours * Second stage * Full dilation to newborn delivery * 1 to 2 hours in nullipara * 30 minutes or less in multipara * Third stage * Delivery of baby to placenta expulstion * 5 to 60 minutes, regardless of parity
45
Abortion
Deliberate termination of a human pregnancy, usually during first 28 weeks
46
Menarche
First menstration
47
Dysmenorrhea
Menstrual cramps (due to uterus contracting)
48
Chlamydia
STD of parasitic bacterium causing infection
49
Intussusception
Telescoping of the bowel into another part of the bowel
50
Epididymitis
Inflammation of the tube at the back of the testicles that stores and carries the sperm
51
How does asthma cause increased risk of spontaneous pneumothorax?
* Asthma predisposes people to pleural bleb rupture (air in between lung and the visceral pleura) * When bronchospasm and hyperinflation increase the pleural pressures (necessary to maintain ventilation) it can cause the bled to rupture, causing pneumothorax * Can also be caused by COPD, cystic fibrosis, pneumonia
52
Signs of uremia
* Pasty, yellow skin discoloration * Uremic frost caused by urea crystals on the skin
53
What positive findings would indicate appendicitis?
* Heel tap test * Rovsings sign * Palpate LLQ and pain in RLQ * Psoas sign * Hand above R knee, have patient raise leg and pain will present in abdomen * Obturator sign * Flex R knee and hip, put lateral pressure to knee, rotate lower leg laterally and causing rotation of femur, causes abdominal pain * Cutaneous Hyperesthesia * Lift folds of skin on abdomen without pinching, get painful response
54
3 causes of non traumatic acute pancreatitis
Gallstones, infection, alcohol use
55
3 causes of non traumatic acute pancreatitis
Gallstones, infection, alcohol use
56
Pancreatitis s/s
* Dramatic, sudden pain in LUQ, epigastric, umbilical pain, or flanks or L shoulder * Vomiting, fever, shock, positive grey turner and cullen signs * SOMATIC pain
57
Cullen sign
Umbilical bruising. Retroperitoneal hemorrhage, pancreatic hemorrhage, AAA rupture
58
Cullen sign
Umbilical bruising. Retroperitoneal hemorrhage, pancreatic hemorrhage, AAA rupture
59
Urine output in adults
about 800 to 2000mL per day 1-2ml/kg/hr
60

small amounts of urine (less than 500mL per day)
61
Anuria
No urine output
62
Fothergills sign
Mass in abdomen
63
Will pyelonephritis by itself cause pain?
NO
64
Lower back pain intermittently radiating to groin?
Renal calculus
65
Does pancreatitis cause upper GI hemorrhage?
NO
66
Do peptic ulcers cause a lower or upper GI bleed?
Upper
67
Lower abdominal and back pain could be what?
UTI
68
What is pelvic inflammatory disease?
* Infection of the cervix, uterus, fallopian tubes, ovaries, and supporting structures. * Usually STD Gonorrhea and Chlamydia * Pain on ambulation * PID Shuffle * Shory, slow, guarding * * Need antibiotics
