A nurse is caring for a client who has a prescription for total parental nutrition (TPN).
Which of the following routes of administration should the nurse use?
Midline catheter.
Central venous access device.
Subcutaneous.
Intraosseous.
The Correct Answer is B
This is because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so a central venous catheter is usually required. TPN should only be used when the intestine is unavailable or unable to absorb nutrients.
Choice A is wrong because a midline catheter is a type of peripheral catheter that can only be used for solutions with low or moderate osmolarity, not for TPN.
Choice C is wrong because subcutaneous administration is not a route for delivering TPN, which requires intravenous infusion.
Choice D is wrong because intraosseous administration is an emergency route for delivering fluids and drugs when intravenous access is not available, not for TPN.

Explanation
Older adults are at higher risk of adverse drug reactions due to multiple health problems, polypharmacy, and decreased renal function.
These factors can affect the pharmacokinetics and pharmacodynamics of pain medications and increase the likelihood of drug interactions, overdosage, or toxicity.
Choice A is wrong because the decreased percentage of body fat does not increase the risk of adverse drug reactions in older adults.
In fact, an increased percentage of body fat can alter the distribution and elimination of some drugs.
Choice C is wrong because an increased rate of absorption does not increase the risk of adverse drug reactions in older adults.
In fact, decreased rate of absorption can occur due to reduced gastric motility and blood flow.
Correct Answer is A
Explanation
The correct sequence for mixing regular insulin and NPH insulin in the same syringe is important to ensure proper dosing. The nurse should follow these steps:
-
Inject air into the NPH (intermediate-acting) insulin vial: Injecting air into the NPH vial first helps to equalize the pressure in the vial, making it easier to withdraw the insulin later. This step is done first to avoid contaminating the regular insulin vial with NPH insulin.
-
Inject air into the regular insulin vial: Next, inject an amount of air equal to the intended regular insulin dose into the regular insulin vial.This also helps to equalize the pressure and makes it easier to withdraw the insulin.
-
Withdraw the regular insulin from the vial: The nurse should withdraw the regular insulin first because it is clear and not contaminated. This prevents any NPH insulin from mixing into the regular insulin vial.
-
Withdraw the regular insulin from the vial: Finally, the nurse withdraws the NPH insulin. Since the regular insulin has already been drawn up, there is no risk of contaminating the regular insulin with NPH insulin.
This sequence ensures that you don't contaminate the vials, and you accurately withdraw the appropriate doses of each insulin type.
