A nurse is providing home safety information for an older adult client who uses a cane. Which of the following statements should the nurse include in the teaching?

A. Apply a warm compress to the IV site: While warm compresses can sometimes help alleviate discomfort associated with certain IV complications, such as phlebitis or infiltration, they should not be applied until the cause of the pain is identified. In this case, removing the IV saline lock is the priority action to assess the site properly.

B. Remove the IV saline lock: Pain above the catheter site during flushing may indicate infiltration or phlebitis, both of which require intervention. Removing the IV saline lock allows the nurse to assess the site for signs of complications such as swelling, redness, or coolness to the touch. Once removed, the nurse can then determine the appropriate course of action, such as reinserting the IV at a different site, applying warm compresses, or notifying the healthcare provider if further evaluation or treatment is necessary.

C. Inject the solution more slowly while flushing the IV saline lock: Injecting the solution more slowly may reduce discomfort during flushing, but it does not address the underlying cause of the pain. If there is infiltration or another issue with the IV site, continuing to flush slowly could exacerbate the problem.

D. Apply firm pressure to the plunger of the syringe during the IV flush to improve patency: Applying firm pressure to the plunger of the syringe during flushing is not appropriate when the client reports pain above the catheter site. This action could potentially force fluid into surrounding tissues, worsening infiltration or causing additional discomfort. It is essential to address the pain and assess the IV site before attempting to flush the saline lock again.

A) 41-year-old with hypernatremia:
Hypernatremia refers to elevated levels of sodium in the blood. While hypernatremia can lead to dehydration and electrolyte imbalances, it does not directly correlate with an increased risk of hypomagnesemia.

B) 72-year-old with chronic alcoholism:
Chronic alcoholism is a significant risk factor for hypomagnesemia. Alcohol abuse can lead to poor dietary intake of magnesium, increased renal excretion of magnesium, and impaired absorption of magnesium in the gastrointestinal tract, all contributing to magnesium deficiency.

C) 79-year-old with bone cancer:
Bone cancer does not inherently increase the risk of hypomagnesemia. However, depending on the treatment modalities and disease progression, the client may be at risk for other electrolyte imbalances or complications associated with bone cancer.

D) 46-year-old with respiratory acidosis:
Respiratory acidosis refers to an acid-base imbalance characterized by elevated levels of carbon dioxide in the blood due to impaired ventilation. While respiratory acidosis can lead to electrolyte imbalances, particularly potassium imbalances, it is not directly linked to hypomagnesemia.
