John is 67 years old and works as a driller in the oil fields. He has a history of coronary artery disease (CAD) and has developed tachycardia. 1. What type of adrenergic blocking drug would mostly likely be recommended and why?
2. John also has a history of heavy smoking for 45 years. What concerns would the nurse have about giving him propranolol (Inderal), a non-selective β-blocker?
3. How does John’s age of 67 years influence his taking β-blockers and going into heart failure?

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.

can i know what the options are for this question ? ?
