Med Errors

Nurses Medications

Published

For our collective benefit, list some of the med errors you've seen committed or caught before they were committed.

The only rules are:

1. No blaming.

2. No naming names.

3. State what the error was.

Examples:

1. Mag and KCl hanging without a pump. ---Both need to be administered on a pump.

2. Regular insulin, pulled up in mg's, not units ---Self-explanatory.

3. Digoxin 0.125 mg po qd ----Given with an apical HR of 42.

4. Order for Vistaril IV ---Never give Vistaril IV.

5. Lopressor 25 mg po bid, 1 tab ----Pt. got 50 mg. because this med only comes in 50 mg tabs and should've read "1/2 tab."

6. PRBCs hung over the 4 hour limit. PRBCs piggybacked into ABTs. ---PRBC total hang time may not exceed 4 hours. This might include time taken from the blood bank in some facilities. ---Never piggyback anything into PRBCs.

7. PRBCs not hung for over 24h with a Hgb of 6.8.

8. "Demerol 100 mg. IVP q2h prn" --Classic case of "too much, too soon."

9. "Percocet 1-2 tabs po q4h prn, Darvocet N-100 1-2 tabs po q4h prn, Tylenol ES gr. X q4-6 h prn" ---Tylenol can potentially exceed 4 gm/day max.

10. Dilantin piggybacked into D5. ---NS yes, D5 no.

Ok here are a few I have seen...

maalox instead of mom

dopamine running at 75ml/hr...should be of 7.5ml/hr

heparin ordered for 50ml/hr...should be 5 ml/hr

2 pt's received wrong meds

cardizem iv for afib infused at 50ml/hr...nurse comes out to see where to get another bag

dilaudid in pca set up for morphine

kefzol ordered for pt with pcn/cephalosporin allergy

I have a good pharmacy error. We had a local pharmacy fill a script that was written for methylphenidate with Methadone. It was even written on the bottle! The mother called us a few days later because her son was sleepy and she checked the medication bottle and realized what it said! Luckily the child was ok. We called and spoke with the pharmacy manager, I am not sure what happened (if anything) to the pharmacist that filled it. It is a good rule to remind patients to ALWAYS double check refills of meds they take routinely!

Near drug error doing the evening pre meal blood sugar check and insulin s/c.

I'm a student i go with a staff nurse to a patient who has been in about a week, Staff nurse picks up drug kardex and read the insluin prescription and reads it off while looking in patient drug locker for insliun pen. Both the dose and pen seen too high to the patient and me who had been working with him the past few days. I talk to the Staff nurse daying don't think it right besides where is his blood sugar chart that where the doc presribe insluin, we had a dicussion it was a busy ward and i was a student but we stopped and found the blood sugar chart,

So a near drug error due to a doctor not discontiuning a standing prescription and not indicating where the drug was being prescribed.

I know I've seen alot of the mistakes that you've all been writing about here happen. The two worst mistakes with fatal outcomes that I've seen happened actually involved the same nurse.

First : TPN hung via pump however the pump rate was set at 1000 AND the volume was set at 1000 which means it ran in over 1 hour. I guess that is one reason to always double check the rate and volume. Patient ended up with blood glucose >700--renal failure, CVVHD but utimately died. Was a 37 year old patient in for some abdominal surgery and that is why she was NPO and on TPN.

Second : Our pharmacy mixed our Dopamine and Septra IVPB's. They were both mixed in 250 cc bags and actually looked the same other than the labels. Nurse "forgot" her glasses that day and couldnt see the labels so she hung the Dopamine instead of the Septra and set the pump to infuse it over 2 hours or 125cc/hr. Dopamine of course didnt infuse for very long until we had a high B/P and heart rate. Patient was 1 day post CABG and needless to say he blew a graft.

That's why you have to do the math and check with someone else. Intuitively, it seems like 1/32 + 1/32 = 1/64, but that's mathematically incorrect, because when you ADD denominators, the denominators stay the same. You'd actually have 2/32 or, simplified, 1/16.

I hope that helps.

PS Thanks for the information, Jacqui!

Just remember that the larger denominator is a smaller amount. for instance, 1/4 is a smaller amount than 1/2

and just a note:

Reading these posts is very humbling. I can't imagine how stressed you must become dealing with all this. I am impressed!

OOOPs! let this be a lesson to me, read the entire thread before responding....I even used the same fractions as an example! Well, you know what they say about great minds.

We give potassium IV through a peripheral line all of the time. We long line it so it dosen't burn and give it slowly(over 1hour) We have not had any problems.

I have also heard to never give vistaril iv. Another nurse told me that it crystallizes in the blood stream? Has anyone ever heard of that?

IV potassium given peripherally is fine however the concentration is different from that that would be given thru a central line. The other writer stated she/he had seen IV potassium given 20meg/50cc which is the central line concentration and if that was given peripherally it would burn and probably cause severe vein inflammation. Peripheral IV potassium concentration is 10meq/100cc.

Thought of two more that are pretty freightening.

Argatroban hung as a IVPB and run over 1 hour (nurse didnt know what Argatroban was and assumed it was an antibiotic).

Heparin hung at 1500 units/hr on a fresh post op carotid patient.

Just remember that the larger denominator is a smaller amount. for instance, 1/4 is a smaller amount than 1/2

i was going to give this same explanation too, but was going to use 1/4 and 1/8 as my example!

i've seen a few drug errors in my time, but had to laugh when one of my mates (who was an ambo as well as a nursing student) told me about his.

he was working one day when he was just coming down with a cold and had an awful sore throat. Went to a call-out to a lady with ?MI, BP through the roof. gave her S/L GTN and transported her. Later that day, throat bothering him, so he reached into his pocket for his throat spray and gave himself a squirt. soon after, started to feel woozy - he'd stuck the GTN in his pocket after using it, and had given his throat a healthy squirt with it! BP was in his boots, but recovered quickly and was highly embarrassed.

One morning in my LTC facility, couldn't wake a resident up. Knew she got morphine sulfate the night before. checked MAR and the nurse had written 5 cc of morphine given (Dose was supposed to be .5 cc) This was verified by pouring out morphine into measuring cup, and sure enough 5 cc was given. Patient didn't make it.

1. pt with pelvic fx had narcotic pain med ordered q6h prn. New grad gave it 2 h 45min early and again 2 h early, b/c the pt wanted it sooner. And she didn't understand why I was upset, she thought that she could do that to "cover until she could call the doc in the am" then she said she thought q6h prn meant every 6 hours and any time in between!

Wolfe - I've seen MOM given instead of Maalox!! It was on nights, and the room was dark, and the nurse was putting it thru an NG tube - patient was a GI bleed, and the doc had ordered Maalox 30cc's q2h.

The nurse coming in, in the morning, discovered the almost empty bottle of MOM. I don't know what it did for his stomach, but he was WELL cleaned out!!

I clarified an order for a nurse once, the pts blood sugar was 200 and the order was hand written, 5U, the nurse thought it looked like 50 units reg and rightly questioned it. This is LTC, they do it all the time. It's a good thing that U isn't acceptable for units anymore. Do the Doc's know :uhoh3: ?
