A nurse is caring for a client who has Stage IV lung cancer and was prescribed opioid medications for pain management. The client is unable to engage in most physical activities. Which of the following manifestations should the nurse anticipate?

Choice A reason:
While it is true that many dietary supplements have not been tested and approved by the government, this is not the most critical information for a client taking nitroglycerin. The primary concern with dietary supplements is their potential interaction with other medications.

Choice B reason:
This is the most important statement for the nurse to include. Dietary supplements, especially those containing L-arginine or other compounds that affect blood flow, can have serious interactions with nitrates like nitroglycerin, potentially leading to dangerously low blood pressure.

Choice C reason:
The effectiveness of dietary supplements for erectile dysfunction varies, and there is indeed a lack of evidence for many of these products. However, the immediate concern for a client taking nitroglycerin is the risk of interaction, not the general effectiveness of supplements.

Choice D reason:
The cost and insurance coverage of dietary supplements can be a concern for clients, but it is not as critical as understanding the potential risks associated with their use alongside prescribed medications like nitroglycerin.

Choice A reason:
Purulent drainage at the intravenous site access site would indicate a more severe infection, possibly grade 3 or 4 on the Infusion Nurses Society's phlebitis scale. This would be associated with more advanced symptoms such as pus formation, which is not characteristic of grade 1 phlebitis.

Choice B reason:
Redness at the intravenous access site with pain is indicative of grade 1 phlebitis according to the Infusion Nurses Society's phlebitis scale. This grade is characterized by erythema and possible pain at the site of the IV insertion, without more severe symptoms such as swelling or streak formation.

Choice C reason:
Red streaks on the affected extremity suggest a progression of the inflammatory response, potentially indicating a higher grade of phlebitis, such as grade 2 or 3. This symptom suggests that the inflammation is spreading along the vein, which is more serious than grade 1 phlebitis.

Choice D reason:
A palpable venous cord in the affected extremity would also suggest a more severe form of phlebitis, likely grade 3. This occurs when a thrombus forms along with inflammation of the vein, leading to a palpable cord-like structure.
