Test Guides

  • Test 2
  • Test 3
  • Test 4
  • Test 5
  • Final exam

Expect at least one question on each drug class. Usually on the big things talked about, so for example

  • Vanco: what makes it special, what is it used for, how is it absorbed, major adverse effects, how is it given and monitored
  • Flagyl: what is it used for, what’s the major adverse effect, what is the major interaction
  • Linezolid: what is it used for? What is the major interaction, what are the food issues?
  • Understand the four basic mechanisms of bacterial resistance
  • Understand the CDC recommendations to reduce bacterial resistance
  • Know the difference between colonization and infection
  • Know the local and systemic signs and symptoms of infection
  • Know the WBC levels and Neutrophils/Bands
  • Know the difference between shift left/right
  • Why is strep throat a big deal?
  • What are the alternatives to penicillin?
  • C. diff, causes and treatments
  • The less time we spent on a drug, the fewer questions will likely be on it.
  • UTI types and drugs
  • Know the types of Hepatitis, how they’re transmitted, which ones can become chronic, and which ones have a vaccine

There will be a question on this new Hepatis C drug: http://www.everydayhealth.com/hepatitis/1209/new-hepatitis-c-drug-approved-by-fda.aspx

Here are the flu articles that I mentioned: http://www.americanthinker.com/2009/05/swine_flu_in_perspective.html http://www.americanthinker.com/2009/10/swine_flu_panic_in_perspective.html

~60 questions Half immune/inflammation and Half pain Also about half patho, half pharm

Generally speaking there will be at least one question on every major topic: So for the immune system things like:

  • Fluid balance (edema control)
  • Inflammatory mediators
  • Complement
  • WBCs of various types
  • Differences between T cells
  • Life cycle of a T cell
  • Same for B cells
  • Four types of antibodies and purpose of each type
  • Four functions of antibodies
  • Types of vaccines
  • Septic Shock
  • DIC
  • Hypersensitivity
  • Wound healing
  • How the immune and inflammatory side work together
  • Pain Tolerance/Threshold
  • Acute/Chronic Pain
  • Steps in pain process
  • Principles of Pain management
  • Addiction
  • All the drugs

Some things in the reading/podcasts that you should know that we did not cover in class Pyrogens Lab tests for inflammation Article on IV Acetaminophen Finally, Do the So You Think You’re Good Quiz on my website (through pain)

70 questions.  35 on Fluids and Electrolytes and 35 on Respiratory.  About half patho and half pharm.

  1. Know your lab values
  2. Know the drugs
  3. Know signs/symptoms of fluid overload and dehydration
  4. Know the major s/s for each electrolyte imbalance.
  5. Know the treatments for each electrolyte imbalance.
  6. Pay particular attention to potassium and calcium
  7. Know your abgs
  8. UNDER NO CIRCUMSTANCES CONFUSE CO2 FOR PaCO2
  9. Know what the implications of acidosis and alkalosis are
  10. Know the basic respiratory A&P
  11. Know at least the names and basic definition of each resp response to disease
  12. Know the basic pathophysiology of Asthma, Emphysema, and Chronic Bronchitis
  13. Review things from previous chapters that might be applicable such as antibiotics and sympathetic response

Some General Tips:

  1. Read the question, and make sure you are answering what it is asking, and not what you THINK it’s asking.
  2. On a short answer, less is more. If I ask for a treatment, just give me the treatment. On the other hand, if I ask you to interpret AND give a treatment, make sure you do both.
  3. You have scratch paper for a reason. You don’t need to explain every detail of why you think the ABG is that. Do that part on your paper, and then just put down the answer in the computer. Partial credit is already built into the answer, so showing your work doesn’t get you any more points.

Anemias and Clotting. about 60 questions.  Half of each.

This test is quite small in amount of content which makes it easier, BUT that also means that the test will be more detailed. You absolutely need to be able to interpret lab values and know of your drugs!!!!

  1.  know your lab values
  2.  know the calculations for heparin:
    1. calculate kg: divide pounds by 2.2;
    2. calculate unit dose: multiply the weight based dose by the weight
    3. calculate the mL dose: divide the unit dose by the concentration
  3.  be ready to interpret CBCs!!!!
  4.  READ THE QUESTION.
  5.  On the short answer ONLY answer what’s being asked.
  6.  On the short answer make sure you answer all parts of a multi part question. (e.g. interpret AND give a treatment)
  7.  morphology of cbc refers to -cytic -chromic
  8.  know the major aspects of hematopoiesis
  9.  know the common s/s of anemia and compensatory mechanism
  10.  know each type of anemia and its treatment
  11.  know the ANC and neutropenia precautions
  12.  know therapeutic ranges for heparin and warfarin (different for different types of problem)
  13.  know the basic physiololgy of clotting
  14.  know the major thromboembolic d/o’s, esp MI,AAA, AF, Stroke, DVT, PE.
  15.  answer what the question is asking.
  16.  know the difference between antiplatelets, anticoagulants, and thrombolytics.
  17.  know blood transfusions and different blood products. know which ones are pooled (i.e., more than one donor per unit) and why that’s important.

A couple things that don’t always get mentioned class:

  1. Aplastic Anemia comes in two forms
    1. Pure RBC Aplasia
    2. Pancytopenia (when RBCs, WBCs, AND platelets are all three low)
  2. Too many RBCS
    1. Polycythemia (often an adaptation to poor oxygenation or living at elevation)
    2. Polycythemia vera (RBCs, WBC, AND Platelets high) usually precursor to cancer
