A nurse is providing teaching at a community health fair about electrical fire prevention. Which of the following information should the nurse include in the teaching?

"Remove a plug from the socket by pulling the cord."

"Check for a tingling sensation around the cord."

"Use three-pronged grounded plugs."

"Cover extension cords with a rug."

Answer and Explanation

The Correct Answer is C

Rationale:
A. "Remove a plug from the socket by pulling the cord.": Pulling a plug out by the cord can damage the wiring and expose live electrical components, increasing the risk of electric shock or fire. The plug should always be removed by grasping the base of the plug itself to ensure safety.

B. "Check for a tingling sensation around the cord.": A tingling sensation indicates faulty wiring or electrical leakage, which poses a serious safety hazard. Rather than checking for it, individuals should immediately stop using any cord that gives off a tingling sensation and report or replace it.

C. "Use three-pronged grounded plugs.": Grounded plugs provide an essential safety feature by redirecting excess electrical current safely into the ground. This reduces the risk of electrical fires and shocks, especially in appliances with metal casings or high power consumption.

D. "Cover extension cords with a rug.": Covering cords traps heat, prevents adequate ventilation, and increases the risk of overheating and fire. Extension cords should remain uncovered and placed in areas where they will not be walked on or damaged.

Correct Answer is C

Explanation

Rationale:
A. White blood cell count 8,000/mm³ (5,000 to 10,000/mm³): A normal white blood cell count indicates that the body is not currently mounting an inflammatory or infectious response. This finding does not place the client at risk for developing a wound infection.

B. Temperature 36.8° C (98° F): A normal temperature suggests that the client is afebrile and not showing signs of infection or systemic inflammation. This finding reflects stable postoperative recovery and is not a risk factor for infection.

C. Body mass index of 32: Obesity increases the risk for surgical wound infection because excess adipose tissue has poor blood supply, impairing oxygen and nutrient delivery needed for wound healing. Additionally, increased tension on the incision site can lead to dehiscence and bacterial colonization.

D. Blood glucose 90 mg/dL (74 to 106 mg/dL): A normal blood glucose level supports effective immune function and normal wound healing. Hyperglycemia, not euglycemia, would predispose the client to infection by impairing leukocyte function.

A. A health care surrogate makes health care decisions when the client is no longer able. B. Advance directives cannot be changed once implemented. C. Assigning a health care surrogate requires legal consultation. D. A client must create a do-not-resuscitate order when completing advance directives.

Correct Answer is A

Explanation

Rationale:
A. A health care surrogate makes health care decisions when the client is no longer able: A health care surrogate, also called a health care proxy, is designated by the client to make medical decisions on their behalf if they become incapacitated.

B. Advance directives cannot be changed once implemented: Advance directives are legally binding but can be revised or revoked by the client at any time while they are competent. Flexibility allows clients to update their preferences as their health status or values change.

C. Assigning a health care surrogate requires legal consultation: While consulting an attorney can be helpful, it is not required to designate a health care surrogate. Most states allow clients to assign a surrogate using standardized forms provided by healthcare facilities or state agencies.

D. A client must create a do-not-resuscitate order when completing advance directives: Creating a DNR order is optional and only applicable if the client wishes to limit resuscitation. Advance directives encompass broader healthcare decisions beyond resuscitation preferences.
