Because on my unit, for 9am meds, nurses go off the 7am VS.
Also, if there are parameters such as "do not give is SBP is <110 or HR is less than 60"---- do you still give it if their BP is still high but their HR is low?
some nruses would say "don't give it because HR is low", and other nurses say, "you should still give it because their BP is high and it helps stabilizes the BP and especially if they are a-fib or have any heart problems--THEY STILL NEED IT"
what do you guys do? follow one or the other parameter or still just give it because they have heart problems despite the BP and hR?
Yes, take BP and HR prior to giving cardiac meds, and follow holding parameters.
Having said that, this is where you need to know your meds, and understand the reasons you are giving them. It drives me bonkers when people refer to all meds that can affect BP as "BP" meds, when in reality, the person may be taking it for rate control, as an antianginal, or to prevent myocardial remodeling post MI. Does the person have multivessel CAD? Do they have cardiomyopathy with a low EF? Aortic valve stenosis? A history of SVT or A-Fib with RVR? Do they have a pacemaker?
In the person who has A-Fib, their BP is more likely to plummet if they go into a rapid rate than it is to be high, and they are more likely to be getting a beta blocker to control their rate than to control their pressures. A missed dose can result in a rapid rate and associated chest pain/pressure, dyspnea, dizziness, and other signs of poor perfusion.
A rate in the 40s does not automatically buy a person pacer pads, as some people live in the 40s and tolerate it just fine. Some people even dip into the 30s regularly while they sleep, and it's okay. That's how they live. How do you know they are tolerating a low HR? You assess them for s/s of poor perfusion. You can also ask the patient about it; many patients with a cardiac history are well aware of their rate/rhythm issues, and can tell you if a low HR is normal for them.
Some people with multivessel CAD will experience chest pain if they skip their beta blocker.
People with a low EF benefit from lower than normal systemic pressures, and an SBP of 120 could easily be considered hypertensive for them.
If the person has a pacemaker, then you can still give the beta blocker because the pacer will pace them if the rate gets too low, or they may already be paced right at 60 (it's not unusual to get a reading of 59 on the pulse ox) and you can't drop their HR even if you wanted to.
Another thing that makes a difference is whether the person has been on this med for fifteen years or if it's a new prescription, or if they've had a recent change in dosage.
Remember that even if a person has a low BP, they can be perfusing their vital organs just fine with a MAP >60.
If you are not working on a cardiac floor and do not have a good working knowledge of these medications and their indications for use, then by all means, follow the holding parameters and call the doctor. However, keep in mind that if the doctor tells you to give it anyway, it isn't necessarily because the doctor doesn't care about the patient or doesn't care about your license, it very well could be because the patient has a cardiac condition that warrants giving the meds even if the result is a vital sign that is outside normal parameters. A doctor worth his or her salt will ask you if the patient is symptomatic, so always assess your patient before calling the doctor with a BP or HR that is not WNL.
I should add to this already lengthy novel that as a Med/Surg nurse, you do not need to be making the clinical judgment calls mentioned above. Experienced cardiac nurses have a greater knowledge and experience base in this area, and are often given leeway by cardiologists to make these types of clinical judgments. The above is simply for the purpose of helping you understand why a person might need a med despite VS that are outside normal parameters. Always take your VS prior to administration and follow your holding parameters and notify the physician.
