Anticoagulants and their actions are described briefly with examples….

  • Thrombin inhibitors – prevents conversion of prothrombin to thrombin thus preventing conversion of fibrinogen to fibrin eg. heparin
  • Low molecular weight heparin – prevents coagulation by blocking coagulation factor 10a eg. Dalteparin, Enoxiparin
  • Clotting Factor inhibitors – Inhibits hepatic synthesis of Vitamin K and related factors eg. Warfarin
  • Platelet inhibitors – Decrease platelet aggregation – eg. Clopidogrel
Nursing consideration – Note PTT for Thrombin inhibitors follow up while check PT and INR for Clotting Factor inhibitors follow up

We have noticed many antibiotics being given to patients, but have anyone enquired to which classes these antibiotics belongs and what is their specific action on pathogens. Lets study that….

  • Aminoglycosides – decrease protein synthesis eg. Gentamycin
  • Cephalosporins – Bind to cell wall causing cell death eg. Cephalexin, Cefazolin
  • Fluroquinolones – Decrease DNA synthesis eg. Ciprofloxacin, Levofloxacin
  • Macrolides – Decrease protein synthesis eg. Azithromycin, Clarithromycin
  • Pencillin – Gind to cell wall causing cell death eg. Amoxycillin
  • Sulfonamide – decrease protein synthesis ed. Doxycycline
  • Eg. Metronidazole – decrease DNA synthesis as well as protein synthesis,  bactericidal, trichomonacidal and amoebicidal

Simple but important points to be noted regarding Hemophilia while preparing for central exams…
  • Hemophilia is an x linked recessive genetic disorder
  • Affected in males, carried through females
  • Two types A and B, A is the classical Hemophilia due to deficiency of Factor 8 and B is Christmas disease due to the deficiency of Factor 9
  • Treatment – important – RICE ie Rest, Ice, Compression and Elevation

Lets discuss about Glomerulonephritis and Nephrotic syndrome. Some striking points are being noted.


          – An immune-complex reaction resulting in an exudative process that narrows the capillaries of the glomeruli; is a complication of having an infection in prior 10–14 days. Organism is usually group A-hemolytic streptococcus
Nephrotic syndrome
           – Due to some disturbance increased permeability of glomerular capillary membranes causing excessive loss of proteins
Main difference in signs and symptoms of Glomerulonephtitis and Nephrotic syndrome
  • increased periorbital edema (both)
  • BP – increased in GN while decreased in NS
  • Edema – Peripheral edema in GN while anasarca in NS
  • Dysuria or oliguria – both
  • Dark colured urine – GN
  • Proteinuia – Massive in NS while moderate in GN
  • Anorexia, head ache, irritablity – both
  • Age group – 6-7 years for GN while 2-7 for NS

Some common problems that pregnant women are facing and their possible cause whether physical or hormonal is listed here with possible remedies…..Hopes its useful

Nausea or morning sickness – Incereased prodn of HCG

Physiological anemia – Increased RBC level by 30% causes decrease in Hct value

Palpitations or breathing difficulty – Pressure applied by uterus on diaphram

Supine hypotension – due to compression of superior venacava by enlarging uterus

The major types of angina are,

Stable Angina or Exertional Angina

– occurs with exertion and relives with rest

Unstable Angina or Preinfarction Angina

– occurs with unpredictable degree of exertion or emotion and severity increases with time

Variant Angina or Prinzmetal’s or Vasospastic Angina

– results from coronary artery spasm, may occur at rest and ST elevation on ECG

Intractable angina

– incapacitating angina – irresponsive to interventions

Post infarction angina

– Cause is residual ischemia

Type of Pain in all angina pectoris is a substernal, crushing, squeezing pain which may radiate to shoulders, arms, jaws, neck or back and which usually lasts less than 5 minutes
