2022-04-18 15:31:44 Beta-blockers e.g. bisoprolol should not be used with verapamil
due to the risk of bradycardia, heart block, congestive heart failure.
This is a typical angina history. Beta-blocker is a first line Angina
prophylaxis. However, this man is taking verapamil for his migraine.
Verapamil should not be used with beta blocker due to the risk of
bradycardia, heart block or even congestive cardiac failure. Therefore,
bisoprolol and metoprolol are incorrect answers. Ibuprofen and digoxin
do not reduce the frequency of angina. Therefore, the next line for
prophylaxis of angina is Nicorandil. باز کردن / نظر دهید

2022-04-14 18:22:52 Witnessed cardiac arrest while on a monitor - up to three
successive shocks before CPR

The 2015 ALS quidelines endorse three quick successive ('stacked')
shocks in cases of monitored and witnessed cardiac arrest (if VF/
pVT).

Chest compressions at a rate of 30:2 would be correct in cases of
cardiac arrest that are not witnessed and monitored, or in PEA/asystole.

Amiodarone 300mg is administered after the third shock (in shockable
rhythms).

2022-04-11 07:37:26 Diabetes is among the factors that increase the risk for bleeding with anticoagulation. Optimal long-term strategies for AF management should be based on a thoroughly integrated consideration of patient-specific factors and the likelihood of success. Selection of an appropriate antithrombotic regimen should be balanced between the risk for stroke and the risk for bleeding.
Factors that increase the risk for bleeding with anticoagulation include:
• History of bleeding (the strongest predictive risk factor)
• Age older than 75 years
• Liver or renal disease
• Cancer
• Thrombocytopenia or aspirin use
• Hypertension
• Diabetes
• Anemia
• Prior stroke
• Fall risk
• Genetic predisposition
• Supratherapeutic international normalized ratio (for warfarin)
