We need some great teachers like you here in Michigan! All the professors in my nursing program are so hard to follow and get mad when we dont understand and ask questions! You have helped me get through my final semester of Nursing school. Thank you!

[@SimpleNursing]

+Stephanie Wesa awesome!!! Do me a HUGE favor copy/paste this onto my Wall of Fame for everyone to see this awesome testimonial facebook.com/simplenursing

[@WDOBBS100]

My life has been saved!! I am so addicted to watching the videos. They make sense whereas nursing school seminars not so much. lol You're awesome Mike!

[@TheXyoojcindy]

I'm so glad I found you on KZbin! I'm a nursing student and love how you break down things. Thank you!

[@monicaperez1230]

love this! thank you for taking the time to do this, you are a big help. Im in an accelerated nursing program and every tip to remember this stuff goes a long way.

[@gabyrios4744]

omg for the first time i understand everything you have made this so simple to understand in my head your a great teacher really thanks

[@TheDolly1121]

This video really helped me to understand how Cardizem works for the heart. I was just released from hospital after being diagnosed with prinzmetal angina. You are brilliant and I love all of your videos. Your way of teaching makes so much sense!

[@lauramilton3971]

A true educator. Thank you!!!

[@shanikachen2534]

Thanks Michael! This makes studying meds much easier....simple explanation. ,

[@MetricZero]

We were told to go memorize a list of about 100 drugs and to understand what they all did and nursing implications and such. This helped organize a majority of those drugs and gave me an easy to remember mnemonic which I could combine with my own. For example! -Pines are like Christmas trees, which is often associated with winter, which has a lot of snow! Snow is white, and so is calcium. Anyhow, thanks.

[@zairamoscoso9928]

Thank you! your videos are so helpful and funny you make me laugh and learn at the same time.

[@catherinegolding9794]

thank you for your videos

[@roxanabarragan3899]

you are freaking amazing.. I love your videos..

[@Maryculligan]

Very helpful

[@trishaadams5079]

Michael I love the way you explain things for those of us not in the medical profession can understand them.i was hoping you could explain my disorder I'm going to describe and maybe have any suggestions on treatment that may work other than Verapamil and morphine. I have been diagnosed with Hemiplegic Migraines which is in my mind a totally misdemeanor since this is not a typical migraine but a symptom of a Inherite nuerological chromosone disorder with a mutated gene involving Chromosone 1 and 19. It's my understanding that part of the disorder is that the calcium channel blockers do not work correctly creating the brain to think my body is having a stroke. This condition runs back six generations in my family which has caused several family members with actual strokes and even death. I am 57 years old and my first one was at the age of 20; so they have progressed over the years and have currently becoming more severe as I age and have a pattern at times. Sunday's the aura and blood

[@aaisham1846]

great video

[@mooretessie]

Just watched this after a few glasses of wine... I like it more now.

[@SimpleNursing]

Thanks! Please explain how we exactly I helped you & we will feature you on the Testimonial page

[@lynnecota9103]

Hi Michael! Love your videos!! Can anyone tell me the name video that was about Drug A? Thanks bunches!

[@TheDolly1121]

I have cardiac spasms...was just diagnosed on Wednesday and my cardiologist put me on Cardizem and aspirin.

[@ateeya888]

So HELPFUL! I couldn't figure out how a vasodialator could decrease BP! I do have a question though...being that Ca+ Channel Blockers are vasodialators, they don't interfere with your ACE inhibitors (vasoconstrictors)?

[@trishaadams5079]

Cont. pressure spikes quickly hence stroke concern, then progresses through several symptoms prior to the uncontrollable spasm and electrical "events which feel like thousands of bees stinging" on the right front of my brain behind the right eye. This progresses to pins and needles down the right side of my body then numbness. It has also caused lies ions in the white matter in my brain and tilted disc syndrome and high ocular pressure. Over the years my medical team have tried almost every kind of medication unti my primary said enough experimenting with seizure and other powerful medications and we now inject morphine to blanket the pain. If I don't control the pain right away it seems to create a life of its own and the symptoms take off leaving me totally debilitated until it stops. They seem to start on Sunday's and I get an injection Monday and if I'm lucky they may or may not start easing down by Wednesday. I have been educating myself on this disorder the best I can Any ideas?

[@emartinsful]

Michael I love your videos , but I disagree. With you. Calcium channel blockers slow inward calcium current in cardiac tissue, thereby having a negative dromotropic, chronotropic and inotropic effect. They may also cause bradyarrhythmias and aggravate left ventricular failure.

[@leyannkev]

ACE does not interfere with Ca+ because it is a VASODILATOR which dilate vessels and thus lowering your blood pressure.. It is adjusted though to clients individual needs.. AGIOTENSIN II this is the potent vasodilator. That is why ACE inhibitor is not use for clients with HPN who also have kidney problem. hope it helps

[@JMikoTV]

what would be the side effects of stopping them. When you dont need them anymore.

[@funkyflights]

What's better, beta blockers or calcium channel blockers for controlling heart rate during exercise ?

[@kennethmccamish4092]

None of the above unless you have a medical reason for needing one.

[@funkyflights]

Kenneth McCamish .... Thanks for pointing out the obvious... Yes I have a medical condition...

[@trishaadams5079]

Cont. Obviously I've had 37 years of poking, prodding, testing, scans of every king by a number of specialist. FHM appears to be a rather new thing for doctors and in my experience most don't have a clue that it's not a typical migraine as the name suggests and typical migraine meds are contradictory to the condition. I'm also a cortezone responder and was actually formally diagnosed by a panel of neurologist during a large conference my primary Doctor went to in Seattle, WA and gave them my file and history in 2006. If you're interested in learning more of my condition and may have some suggestions that do not include narcotics I'd love to message you more. Thank you for your time. Trisha Adams. I have a different email address if you might want to know more. Thanks again for your time. For those who haver never experienced this rare disorder their are no words to explain what it does phyiscally, emotionally and morally to the person.....

[@RNgalli27]

omg i love you in the name of phamacology lol. this is stuff nursing school hasnt been able to get me to remember and even giving the drugs at work over the past four years...i suck at memorizing so i always forget..but my goodness..i wont forget again. your AWSOME!!

[@RNgalli27]

I intend to check out EVERTHING. I just started my masters for NP and pharmacology is next semester so I'll be tuning in religiously

[@RNgalli27]

GotchA..I'll check it out

[@officialbabykanine]

You da man Mike

[@leyannkev]

you'll have shortened ST segment.. and widened T wave for hypercalemia..

[@MetricZero]

Add me to the list of people you've helped. Thanks.

[@joannelong356]

Why do we figure out , "Why is the calcium coming there when not suppose to?"

[@joannelong356]

I mean why don't we figure out?

[@Th3wat3rbaby]

Your veins have channels in them? Dude, what?

[@SimpleNursing]

Th3wat3rbaby yup little valves that act as channels to prevent back flow of blood

[@SimpleNursing]

Th3wat3rbaby yup veins have valves

[@kennethmccamish4092]

Okay. What he means are the ion channels in actual cells. Each cell in your body has these channels to control which ions (electrolytes) can come in or leave the cell. One such channel is the calcium channel. The cells of the tiny smooth muscles along the veins and arteries have such channels. These smooth muscles are around the blood vessels in a donut-shape so they can contract and put more pressure on the blood vessels or they can relax and cause less pressure. When they let calcium flow in the muscle cells contract and tighten so by blocking these channels (like with amlodipine for example) we can cause them to relax, thus lowering blood pressure. (There are a lot more effects caused by calcium channel blockers but this is an important one. When the blood vessels are less constricted, blood pressure drops)

[@maried5085]

I've read Amlodipine depletes apoptosis and could cause cancer. Please explain.😊

[@elizabethdiaz283]

I love your teaching style, but you sounds a lot like Barney.
