PLease do not always give Lantus.
Obviously, healthcare settings vary (LTC, med/surg, ICU,...). I work in the ICU. If you have a pt with poor PO intake with scheduled Lantus, it may not make sense to give a big whopping dose of Lantus if their gluc is 90-100-whatever.
If you have a sedated pt on a vent, with tube feeding being held for whatever reason, and a pre-Lantus gluc of ~100-120, PLEASE consider holding the Lantus (especially if Lantus was ordered when the pt was receiving tube feedings). I can speak from personal (painful) experience that if you give a whopping dose of Lantus for pts like this, you may be quite surprised at the resulting Critical Low gluc 4-6 hours later.
Always question whether to give a med or not. Please NEVER blindly give a med (especially insulins, electrolytes, & antihypertensives) "just because it's ordered." Take the time to question the order, the pt-specific circumstances, most recent labs, and just plain common sense.
I'm not a robot - I'm a nurse with the requisite training, critical thinking skills, and willingness to question orders when appropriate.
