While beta blockers have no value in the treatment of an acute angina, nifedipine immediate release (oral or sublingual) can help with an acute angina attach. However, immediate release nifedipine is not recommended to treat an acute angina attach. Why?
A patient has tachycardia and has amiodarone infusing at 15 mL/h. The amiodarone concentration is 300 mg in 500 mL. At what rate, in mg/min, is the amiodarone infusing? Round to the tenth if applicable. A patient with a dysrhythmia has procainamide ordered at 2 mg/min. The concentration is procainamide 4g in 100 mL of D5W. How Many mL/h should the IV pump be programmed for? Round to the tenth if applicable. The patient is ordered to receive 16 units/h of regular insulin. Available is 200 units of regular insulin in 250 mL of 0.9% NS. At what rate in mL/h should the infusion pump be set at? Round to the tenth if applicable .

Antihypertensive treatment with calcium channel blockers (CCBs) is often offered to patients with stage 2 hypertension. Please describe the intracellular signaling events, mechanisms of action on blood vessels and important adverse effects of CCBs. In addition, describe considerations such as the age of a patient when prescribing a CCB at the first stage of antihypertensive therapy according to NICE guidelines.
A patient with chronic-stable angina is on prophylactic beta-blocker therapy, with sublingual nitroglycerin used PRN (as needed) for managing acute angina. One day he experiences particularly severe angina and takes the usually recommended dose of sublingual nitroglycerin (NTG). His discomfort is not reduced at all. Seeking relief, he repeats the usual recommended dose of NTG dose 6 times over a period of about 10 minutes, and now has taken far too much of the nitrovasodilator. An electrocardiogram taken by the paramedics, who were called for the patient’s emergency, shows changes consistent with myocardial ischemia. The patient incurs a massive infarction, goes into cardiac arrest, and cannot be resuscitated. Which of the following is the most likely cause of or contributing factor to the patient’s ultimately fatal response to the excessive dosage of NTG? Assume the patient was taking no other drugs except the NTG and a beta-blocker. Cyanide, or toxic metabolite of NTG, accumulated.…
