The court is shown a 15% dextrose dose, plus sodium chloride, is administered for 7pm on August 5. The nurse has signed for that medication administration.
The nurse is also a co-signer for medication at 2am on Thursday, August 6.
The nurse explains the practice was someone from the day shift (in this case, herself) would co-sign for the drug during the day, then she would in practice text the person who was administering it to confirm it had been administered, and that the scheduled dose could be taken 'off the system' and wasn't at risk of being administered twice.

Ben Myers KC, for Letby's defence, asks about the administration of the drugs, and how they are administered.
The nurse says the 10% dextrose would come in 500ml bags, and can be divided up on the unit for infusions, or come available via the pharmacy in 50ml pre-made doses.
The nurse says she does not have an independent recollection of the event.
She confirms if the long line is tissued, it cannot be used again.
Mr Myers says if the long line is changed, then everything else is changed to avoid infection, including the TPN bag. The nurse confirms that would be the case.
Mr Myers: "You wouldn't put up an old [TPN] bag, would you?"
The nurse: "I wouldn't, no. And we wouldn't have put it up as we would have documented that."
3:08pm
Mr Myers says as a general rule, TPN bags would run for 48 hours unless there was a problem, and there would be a stock of maintenance bags in the fridge.
Mr Myers says one of those would have been used in the course of this. The nurse agrees.
The nurse says such bags are checked every night and if any were being used or out of date, then the stock would be replenished.
3:10pm
Simon Driver, for the prosecution, asks about the stock bags in the refrigerator.
He says every night, a check would be undertaken to see if any had been used.
He asks how the checker would know if they had been used.
The nurse says if there weren't the stock five TPN bags in the fridge, new ones would be ordered.
The refrigerator would have 'start-up' TPN bags and 'maintenance' TPN bags of nutrition.
The nurse says there may be fewer 'target stock' of the 'start-up' TPN bags.
3:11pm
Each of the bags would have a dated 'shelf life' the court hears.
The nurse says the bags would not be ordered in any particular fashion in the fridge.
3:15pm
A video of glucose/dextrose administration is played to the court.
The procedure is described as a 'two-person procedure'.
