A nurse is collecting a capillary blood sample from an older adult client. After puncturing the client's finger, the nurse is unable to obtain an adequate amount of blood. Which of the following actions should the nurse take?

Choice A Reason:
Setting the maximum water heater temperature to 54.4° C (130° F) is appropriate. This temperature is too high and could pose a burn risk, especially for someone with impaired vision who might not easily detect very hot water.

Choice B Reason:
Painting the edges of steps for contrast is appropriate. This measure helps increase visibility by creating a visual contrast between the edges of steps and the surrounding area, aiding the individual in identifying the steps more easily, even with reduced vision.

Choice C Reason:
Securing extension cords across walkways is inappropriate. Placing extension cords across walkways can create tripping hazards, particularly for someone with vision loss who may have difficulty seeing these obstacles.

Choice D Reason:
Using 40-watt bulbs to light hallways is inappropriate. While adequate lighting is crucial for individuals with vision impairment, using only 40-watt bulbs might not provide sufficient illumination. It's recommended to use higher-wattage bulbs or brighter lighting sources to ensure better visibility in the home.

A. Check a client's peripheral IV site for redness or swelling.
This task involves assessing the client's IV site for signs of complications. While it requires observation and reporting, it may involve some interpretation and judgment. This task is better suited for a licensed nurse.

B. Measure the intake and output of a client who has received furosemide.
Measuring intake and output is a routine task that involves quantifying the fluids a client consumes and eliminates. This is a task that can be appropriately delegated to an assistive personnel (AP) under the supervision and direction of the nurse.

C. Reinforce teaching with a client about crutch-gait walking.
Teaching requires a level of education, explanation, and clarification that goes beyond routine tasks. This is typically a nursing responsibility and should not be delegated to an AP.

D. Assess the pain level of a client who has received acetaminophen.
Pain assessment involves subjective information, and determining the appropriate response may require clinical judgment. This task is better suited for a licensed nurse.
