In assessing an older adult, you question his cognitive skills when you notice that

A. Assist with obtaining informed consent from the client.
Explanation: Informed consent is a critical aspect of healthcare procedures, but it requires the patient to have the capacity to understand and make decisions. In this scenario, the client is intubated and on mechanical ventilation, which might compromise their ability to communicate effectively. If the client lacks capacity, obtaining consent from the durable power of attorney (POA) is more appropriate.

B. Refer to the client's advance directive for a name.
Explanation: Advance directives, including the durable POA, provide guidance on a person's wishes for healthcare decisions when they are unable to communicate. However, the advance directive may not always specify a particular person's name for decisions related to specific medical interventions. The key consideration in this situation is to determine the current decision-making capacity and involve the appropriate decision-maker if needed.

C. Determine the client's inability to make reasonable decisions.
Explanation: This is the correct answer. In this scenario, the nurse should assess the client's capacity to make decisions. If the client lacks capacity, the durable POA can be activated to make healthcare decisions on behalf of the client. Capacity involves the ability to understand relevant information, appreciate the consequences of decisions, and communicate a choice.

D. Use the oral trail-making test to measure cognitive function.
Explanation: The oral trail-making test is a cognitive screening tool, but it may not be suitable in this critical care scenario with an intubated and mechanically ventilated patient. Moreover, the primary concern in this situation is determining the capacity to make healthcare decisions, which requires a more comprehensive evaluation than a specific cognitive function test. The focus should be on decision-making capacity rather than a cognitive assessment.

B. Provide nutritious food according to the residents' expressed food preferences.

Explanation: Offering nutritious food based on residents' preferences can enhance their satisfaction with meals, making them more likely to eat and maintain adequate nutritional intake. Taking individual preferences into account helps create a more person-centered approach to nutrition.

D. Distribute "med-pass" nutritional supplements.

Explanation: Nutritional supplements may be beneficial for residents who have difficulty meeting their nutritional needs through regular meals. "Med-pass" supplements can be distributed with medications or as a separate supplement to enhance calorie and nutrient intake, especially for those with specific dietary requirements.

The other options are not recommended:

A. Develop a seating chart for the main dining room based on the unit to facilitate a more organized and efficient meal delivery.

Explanation: While organization and efficiency are important, creating a seating chart based on the unit might not directly address the nutritional status of residents. Instead, focus should be on providing appetizing, nutritious meals and accommodating residents' preferences.

C. Replace the fluorescent lighting with candles at every table to create a cozy, restaurant-like atmosphere.

Explanation: While creating a pleasant dining environment is important, replacing fluorescent lighting with candles may not be practical or safe in a healthcare setting. Moreover, the emphasis should be on the nutritional content of the meals rather than the ambiance.
