3. choose which drug or treatment is needed
4. Write the Rx and start tx
5. Educate and counsel the pt
6. monitor effect of treatment
2). Who rx guideline 1
Ans: Define the pt's problem . This forms the basis for choosing and rx-ing the correct
treatment.
Consultation should include: complaints, symptoms, diagnosis and relevant
characteristics like co-morbidities, co-medication, pregnancy, drug allergies
3). Who rx guideline 2
Ans: Specify the therapeutic objective. What needs to be treated?

, 7).
Ans: Monitor the treatment.
8). Coreg (carvedilol)
Ans: *beta blocker used to treat mild to severe CHF, left ventricular dysfunction
following MI, HTN.
*works by causing vasodilation to the peripheral vasculature to decrease the workload on
the heart.
*Non selective beta blocker and Alpha-1 blocker
*3rd generation beta blocker
*particularly useful in African Americans
*Dose: 0.625 mg-25mg PO BID with food
*administering with food helps prevent postural hypotension
*Education: don't skip doses, take with food
9). Hypersensitivty reactions: mnemonic acid
Ans: 1. A-allergic
2.C-cytotoxic
3.I- Immune complex deposition
4. D-delayed
10). Type i hypersensitivity
Ans: A-allergic
*IgE mediated- quick onset after exposure
*production of IgE after antigen exposure.
*urticaria, wheezing, rhinitis, anaphylaxis
11). Type ii hypersensitivity
Ans: C-cytotoxic
*cytotoxic/antibody mediated
* drug binds to RBCs and is recognized by antibody-usually IgG
*complement and cytotoxic T cells are activated
*Rare response
12). Type iii hypersensitivity
Ans: I-immune complex/IgG/IgM mediated
*antibodies are formed against soluble antigens. ANtigen-antibody complexes are
PaperStoc.com Page 2 of 16
, deposited in tissues such as joints and lungs.
*cause serum sickness. Ex: ceclor (antibiotic)
13). Type iv hypersensitivity
Ans: D-delayed- delayed or cell mediated
*cytotoxic T cells are activated
*poison ivy, latex, etc
*causes contact dermatitis
*cytokine storm if there is repeated exposure
14). Grapefruit juice
Ans: *increases drug toxicity
*don't drink with SSRIs, calcium channel blockers, statins, benzos
*increases absorption and decreases the metabolism
15). Atropine-class/mechanism of action
Ans: *anticholinergic
*inhibits action of acetylcholine and blocks the PNS.
*Increases HR by increasing conduction int eh SA and AV node
16). Atropine- indications
Ans: *symptomatic bradycardia (sinus, junctional, AV blocks, causing significant
hypotension, ventricular ectopy, angina, etc.)
*organphosphate poisoning
* RSI in peds
*beta blocker and calcium channel blocker overdose
17). Atropine- contraindications
Ans: *tachycardia
*HTN
*hypothermic bradycardia
*narrow angle glaucoma
