A nurse is assessing a client who has a pressure injury. Which of the following findings should the nurse expect as an indication the wound is healing?

A. Clean surfaces with chlorhexidine is not appropriate for Clostridium difficile (C. difficile). The recommended cleaning agent for C. difficile spores is bleach, not chlorhexidine, as bleach is effective in killing the spores.

B. Place the client in a protective environment is not necessary for C. difficile. Protective environments are typically used for clients with immunocompromised states, such as those undergoing chemotherapy or bone marrow transplants, not for clients with C. difficile.

C. Wash hands with alcohol-based hand rub is not effective for C. difficile. Alcohol-based hand sanitizers do not kill C. difficile spores. The recommended method for hand hygiene is washing with soap and water to physically remove the spores.

D. Obtain a stool specimen with gloves is the correct action. When collecting a stool specimen from a client with C. difficile, gloves should always be worn to prevent transmission of the bacteria. C. difficile is highly contagious and requires strict infection control practices.

A. Metabolic acidosis is not typically associated with excessive ingestion of antacids. Antacids, especially those containing aluminum, calcium, or magnesium, are more likely to cause alkalosis, not acidosis.

B. Respiratory acidosis is caused by impaired gas exchange (e.g., in conditions like COPD or hypoventilation) and is unrelated to antacid ingestion.

C. Metabolic alkalosis is the correct answer. Excessive ingestion of antacids, particularly those containing sodium bicarbonate or calcium carbonate, can lead to an increase in bicarbonate levels, resulting in metabolic alkalosis. Symptoms can include confusion, muscle twitching, and respiratory depression.

D. Respiratory alkalosis is caused by hyperventilation, not antacid ingestion. It results from excessive loss of carbon dioxide, which is not associated with the use of antacids.
