Q

True or False:

Only use EPO if pt is on dialysis.

A

I guess it’s true?

Apparently White said that - it’s in the docs.

Seems weird to me but who knows, just give it a 5 and move on :)

25
If there is an acute bleed, how long might it take before H+H levels change?
24-48 hours
26
At what Hgb level should you definitely be considering transfusion?
7 or lower
27
In a CKD patient with anemia, what drug should you definitely think about prescribing?
Epogin
28
What do you use Neutrogin for?
neutropenia
29
Ohhh, you're halfway there
Woahhhhh livin' on a prayer (but really, livin' on a prayer that I pass on Monday)
30
In what conditions is lower extremity claudication common in?
Tobacco use, HTN, DM
31
What is the DOC for claudication? | (and peripheral artery disease)
Cilostazol (Pletal) But a walking program will do wonders!!!
32
What is the MOA of Cilostazol (Pletal)?
phosphodiesterase inhibitor inhibits plately phosphodiasterase thus preventing aggregation
33
What do you prescribe for pernicious anemia?
lifelong B12 injection **IM** DOC = cyanicobalamin B12
34
What happens in children when they overdose on iron?
Iron toxicity! Iron leeches out into their kidney and liver, causing damage
35
How do you counteract iron toxicity?
DOC = Deferoxamine (desferal)
36
What is the MOA of deferoxamine (desferal)?
Iron chelator Chelates iron from hemosiderin, ferritin, and transferrin
37
How long does it take to deplete B12 stores in an otherwise healthy patient?
3-5 years
38
If a patient has Vit B12 deficiency, what happens if we treat with JUST folate?
Sx will improve, but neuropathy will continue and may be irreversible
39
What is the DOC for knee/hip replacement surgery?
Rivaroxaban (Xarelto)
40
How should you advise your patient to take Rivaroxaban (Xarelto)?
Take w/ food to increase bioavailability
41
If you reeeeeaalllyyy would like to put your pt on Xarelto or Pradaxa but you CAN'T, then what should you put them on?
Bridge: Low molecular weight heparin (Lovenox) Ultimately: Warfarin (Coumadin) Because warfarin (coumadin) works slowly, but you want immediate response w/ bridge
42
What labs will test Warfarin (Coumadin)?
PT/INR
43
What labs will test Heparin?
PTT
44
What is the DOC for a PE?
low molecular weight heparin (lovenox)
45
In what cases would you want to use Fondaparinux (Arixtra) over LMW heparin (lovenox)?
If pt has had adverse rxn to any type of heparin If pt gets TTP from using heparin
46
What's the safety difference between heparin and LMW heparin (lovenox)?
you usually want to use heparin because it is easier to adjust the dosage and there is a drug to counteract it if you overshoot Use LMW heparin if small problem, or if pt developed HIT/TTP
47
What is the DOC for DVTs?
Still LMW heparin (lovenox)
48
What is the irony about the complication of heparin?
Pt can bleed too heavily OR can have a hypercoagulable state
49
How are you going to treat a patient who is status post acute MI?
Aspirin (ASA) AND Clopidogrel (Plavix)
50
What is the MOA of aspirin?
anti-platelet drug **irreversible inactivation** (via acetylation) **of cyclo-oxygenase**. **inhibits synthesis of thromboxane A2** prevents platelet aggregation and vasoconstriction by thromboxane A2
51
What is the MOA of Clopidogren (Plavix)
Platelet ADP inhibitor Irreversibly **blocks ADP receptor on platelets, preventing platelet/fibrinogen binding** and platelet aggregation
52
What if your patient is status post acute MI, and has an ASA sensitivity?
rx only Clopidogrel (Plavix)
53
Your patient has A-fib and mitral valve stenosis. What drug is she NOT a candidate for? What is the DOC?
NOT candidate for Dabigatran (Pradaxa) or Rivaroxaban (Xarelto) DOC = Warfarin (Coumadin) Non-acute, so NO bridge therapy.
54
What is the MOA of Warfarin (Coumadin)?
Blocks Vit K-mediated carboxylation of clotting factors **2, 7, 9, 10** protein C, S
55
Your patient is on warfarin (coumadin). Where do you want his INR? What do you do if INR is elevated?
Want INR at 2-3 If elevated to ~12, rx Vit K (Mephyton) If elevtaed to ~6, just skip a dose of Warfarin
56
If a patient is on Warfarin w/ a high INR and you Rx Vitamin K, what can happen?
Warfarin resistance can occur for 1-2 weeks after giving the Vit K
57
What is the shelf life on Dabigatran (Pradaxa)?
Unopened: 4 months Opened: 30 days
58
Why would you Rx Warfarin (Coumadin) over Pradaxa?
Warfarin has a longer shelf life and less side effects
59
BUT what is Warfarin's PG category?
X
60
Which drug is cheaper: Riveroxaban (Xarelto) or Dabigatran (Pradaxa)?
Pradaxaaaaaaaaaaa (Also, food has no effect on Pradaxa unlike Xarelto)
61
What is the MOA of a tPA like Alteplase (Activase)?
plasminogen activator activates plasminogen bound to fibrin **"a drug to lyse and destroy clot formation"**
62
Realistically, when do we ever use tPA anymore?
Not often. Still used in stroke patients if a) non-hemorrhagic and b) pt meets time criteria
63
What drug is used to counter the effects of tPAs?
You must **inhibit fibrinolyses** Therefore, use **Aminocaproic acid (Amicar)**
64
Oh hey, think back to the last exam. What do we have to monitor when we put a patient on methotrexate?
Lung function! Can lead to pulmonary complications, esp in COPD patients
65
What drug do you give to reverse the effects of Heparin? And again, how will you monitor Heparin?
Protamin sulfate Monitor PTT
66
What drug do you give to reverse the effects of Warfarin (Coumadin)? And again, how do you monitor?
Vitamin K Monitor with PT/INR
67
What's a problem-free philosophy?
