A nurse manager observes an assistive personnel (AP) incorrectly transferring a client to the bedside commode. Which of the following actions should the nurse take first?

Choice A Reason:
Telling the client that their blood alcohol level will be checked is incorrect. Threatening the client with other forms of testing may not be ethically or legally appropriate, especially if the client has refused the initial request. It's important to respect the client's autonomy and right to refuse testing.
Choice B Reason:
Informing the client that a catheter will be inserted is incorrect. Inserting a catheter against the client's will is invasive and would constitute a violation of the client's autonomy and bodily integrity. It is not an appropriate action.
Choice C Reason:
Documenting the client's refusal in their chart is correct. Documenting the client's refusal is essential for accurate record-keeping and ensures that the healthcare team is aware of the client's decision. It also helps protect the nurse and the healthcare facility in case of any legal or ethical challenges related to the client's refusal.
Choice D Reason:
Assessing the client for urinary retention is incorrect. While urinary retention may be a concern in some cases, it is not the immediate action to take when a client refuses to provide a urine sample. The priority is to respect the client's autonomy and document their refusal appropriately. If there are clinical indications or concerns about urinary retention, they can be assessed separately and addressed accordingly.

Choice A Reason:
White blood cell count (WBC) is incorrect. Melena, which is the passage of black, tarry stools, is typically associated with upper gastrointestinal bleeding rather than an infection. While changes in WBC count might occur in response to infection or inflammation, it is not the primary laboratory test to monitor in response to melena.
Choice B Reason:
Glucose is incorrect.
Glucose monitoring is important for assessing blood sugar levels, particularly in diabetic patients or those at risk of hypoglycemia or hyperglycemia. However, it is not directly related to the presence of melena, which indicates gastrointestinal bleeding.
Choice C Reason:
Blood urea nitrogen (BUN) is incorrect. Blood urea nitrogen (BUN) levels can indicate renal function and hydration status, but they are not specifically related to the presence of melena. Monitoring BUN may be relevant in other clinical contexts, such as assessing kidney function or dehydration, but it's not the primary laboratory test to monitor in response to melena.
Choice D Reason:
Hematocrit is correct. Melena indicates upper gastrointestinal bleeding, which can lead to a significant loss of blood. Monitoring the hematocrit level is crucial in this context because it helps assess the severity of bleeding and guide appropriate interventions such as blood transfusions if necessary. A decrease in hematocrit indicates a decrease in the volume of red blood cells, which reflects blood loss and the need for further evaluation and management.
