A nurse in an assisted living facility is collecting data from an older adult client who fell in their room and hit their head on the dresser. Which of the following findings is the nurse's priority?

Choice A Reason:
Before administering any medication, it is crucial to verify the client's allergies to prevent adverse reactions. This step is paramount as it ensures patient safety and is a standard practice in medication administration protocols.

Choice B Reason:
Locating the correct injection site is essential for the efficacy of the drug and to minimize discomfort or complications. The area 5 cm to the right or left of the umbilicus is chosen because it is typically well-padded and has a lower risk of hitting bone or major blood vessels.

Choice C Reason:
The presence of an air bubble in the prefilled enoxaparin syringe is necessary to ensure the full dose is administered. Enoxaparin is an anticoagulant medication, and the air bubble does not pose a risk when injected subcutaneously but helps to clear the syringe of medication.

Choice D Reason:
The technique of pinching the skin and inserting the needle at a 90-degree angle is used to create a skinfold for subcutaneous injections. This method helps to ensure that the medication is delivered into the subcutaneous tissue rather than into muscle or dermis.

Choice E Reason:
Injecting the medication slowly and without aspirating is specific to subcutaneous injections like enoxaparin. Aspiration is not recommended for subcutaneous injections as it can cause tissue damage and is unnecessary since large blood vessels are not present at the recommended injection sites.

Choice A Reason:
Expecting black tarry stools is not a typical instruction after an upper gastrointestinal series with barium contrast. Black tarry stools can indicate gastrointestinal bleeding, which is unrelated to the ingestion of barium contrast.

Choice B Reason:
Following a low-fiber diet for several days is not necessary after an upper gastrointestinal series with barium contrast. In fact, a normal or high-fiber diet may be encouraged to help pass the barium through the digestive system.

Choice C Reason:
Taking an over-the-counter antidiarrheal medication is not a standard instruction post-barium contrast procedure. Barium contrast can cause constipation, so taking antidiarrheal medication would be counterproductive.

Choice D Reason:
Increasing fluid intake is an important instruction for a patient after an upper gastrointestinal series with barium contrast. Drinking extra liquids helps to move the barium out of the intestines and prevent constipation, which can be a side effect of barium contrast.
