A client with renal calculi is experiencing hematuria and reports severe flank pain.
Which intervention should the nurse implement first?

Stomatitis refers to the inflammation of the mouth and oral mucosa, which can cause pain and difficulty swallowing. In the context of a client receiving chemotherapy, stomatitis is a common side effect that can occur due to the effects of chemotherapy on rapidly dividing cells, including those in the oral cavity. When a client develops stomatitis, it is important for the practical nurse (PN) to obtain information about the client's ability to swallow during a focused assessment. This is because stomatitis can significantly impact a client's ability to eat and drink comfortably, which can lead to dehydration and malnutrition. Assessing the client's ability to swallow helps determine the extent of the issue and guides appropriate interventions and support.

Let's briefly evaluate the other options:

a) Urinary output.
Urinary output is not directly related to stomatitis. Stomatitis primarily affects the oral cavity, and its impact on urinary output is minimal or nonexistent. While monitoring urinary output is important for assessing hydration status, it is not the priority in this situation.

c) Frequency of bowel movements.
The frequency of bowel movements is unrelated to stomatitis. Stomatitis primarily affects the mouth, and its presence does not directly influence bowel movements. Assessing bowel movements may be relevant for other concerns, but it is not specifically related to stomatitis.

d) Blood pressure while standing.
Blood pressure while standing, also known as orthostatic blood pressure, is not directly relevant to stomatitis. Stomatitis primarily affects the oral cavity and does not typically have a direct impact on blood pressure. Assessing blood pressure while standing may be appropriate for other health concerns, such as orthostatic hypotension, but it is not the priority in this situation.

In summary, when a client receiving chemotherapy develops stomatitis, the practical nurse should focus on assessing the client's ability to swallow as it directly relates to the impact of stomatitis on the client's nutrition and hydration.

Choice A rationale:

The client's statement, "I should avoid foods that are high in vitamin K," indicates an understanding of the medication. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-containing foods helps maintain a stable INR (International Normalized Ratio) and warfarin's effectiveness. Clients on warfarin should be educated about avoiding drastic changes in their vitamin K intake.

Choice B rationale:

Taking warfarin with food or on an empty stomach doesn't significantly impact its efficacy. Therefore, this statement is not indicative of the client's understanding of the medication.

Choice C rationale:

The statement "I should report any unusual bleeding or bruising to my provider" is important but doesn't specifically reflect an understanding of warfarin. It's a general caution for anyone taking anticoagulants.

Choice D rationale:

While it's important to avoid excessive use of medications like aspirin that can increase the risk of bleeding, this statement doesn't directly demonstrate an understanding of warfarin itself.
