A nurse is collecting data from a client. The nurse should identify that which of the following manifestations is an indication of a candida infection?

Among the procedures listed, the placement of a central venous catheter is an invasive procedure that typically requires informed consent. This procedure involves inserting a catheter into a major vein, usually in the neck, chest, or groin, and it carries potential risks and complications that need to be explained to the client.

​​​​​​​

The other procedures listed may require consent but are typically considered less invasive, and the need for informed consent may vary depending on institutional policies, client condition, and other factors:

Administration of an iron injection using the 2-track technique: While this procedure involves the administration of medication, it is usually considered a routine injection and may not require specific informed consent.

Irrigation of a wound with antibiotic solution: This procedure involves the irrigation or cleansing of a wound with a solution, which is typically part of routine wound care. Informed consent may not be specifically required for this procedure unless there are specific circumstances or considerations.

Insertion of a nasogastric tube: Inserting a nasogastric tube is a common procedure used for various purposes, such as administering medications or feeding, or obtaining gastric contents for diagnostic purposes. Informed consent may be required depending on the circumstances, client's condition, and institutional policies, but it is generally considered a less invasive procedure compared to the placement of a central venous catheter.

Yellow patches in the mouth are a common manifestation of a candida infection, specifically oral candidiasis or thrush. Candida is a type of yeast that can overgrow in the mouth, leading to the development of creamy or yellowish-white patches on the tongue, inner cheeks, or other areas of the mouth. These patches may be accompanied by redness, soreness, and discomfort.

Hearing loss is not a common symptom of candida infection. Hearing loss can be caused by various factors, such as ear infections, fluid buildup, or damage to the auditory system, but it is not directly related to candida overgrowth.

Brittle nails can be caused by multiple factors, such as nutritional deficiencies, trauma, or certain medical conditions, but it is not a specific manifestation of a candida infection.

Night sweats can occur due to various reasons, including hormonal changes, infections, medications, or certain medical conditions, but they are not typically associated with candida infections specifically. Night sweats are not a specific or definitive indicator of a candida infection.
