A nurse is applying cold therapy to a client's face following oral surgery. The nurse should identify that which of the following is a therapeutic effect of cold therapy?

Increased tissue metabolism

Reduced blood coagulation

Decreased edema formation

Improved blood flow

Answer and Explanation

The Correct Answer is C

A. Increased tissue metabolism: Cold therapy slows tissue metabolism by reducing enzymatic activity and cellular function, which helps minimize inflammation and tissue damage, not increase metabolism.

B. Reduced blood coagulation: Cold therapy typically promotes vasoconstriction, which supports blood clotting rather than reducing coagulation. This effect can help control minor bleeding after surgery.

C. Decreased edema formation: Cold therapy causes vasoconstriction, which limits fluid accumulation in tissues and reduces capillary permeability, leading to less swelling and edema formation at the surgical site.

D. Improved blood flow: Cold causes vasoconstriction, which decreases blood flow temporarily. This helps limit inflammation and edema but does not enhance circulation during application.

Correct Answer is A

Explanation

A. Removing blankets from the client helps reduce external heat sources and allows body heat to dissipate, which can aid in lowering the elevated temperature. This action supports the body’s natural cooling mechanisms and provides comfort during a febrile state.

B. Placing cold packs on the axillae can help lower body temperature by cooling major blood vessels near the skin’s surface. However, this method may cause discomfort or shivering, which can paradoxically increase metabolic heat production and is less preferred than removing excess coverings.

C. Using a fan to blow air across the client promotes evaporative cooling, but if the client is shivering or chills are present, this can increase discomfort and cause the body to generate more heat. Fans are best used when the client is comfortable and not experiencing chills.

D. Giving an alcohol sponge bath is generally discouraged because alcohol is rapidly absorbed through the skin and can cause toxicity. Additionally, it can cause vasodilation, which might lead to increased heat loss and potential hypothermia if not carefully monitored.

A. Tell the client to think about something else. B. Tell the client that everything will be okay. C. Ask the client to describe their support system. D. Ask the client why they're unable to cope.

Correct Answer is C

Explanation

A. Tell the client to think about something else: Redirecting the client's thoughts without addressing their emotional distress can be dismissive. It does not support emotional processing or help the nurse assess the client’s coping needs.

B. Tell the client that everything will be okay: Offering false reassurance minimizes the client’s feelings and may hinder open communication. It does not validate their experience or help develop coping strategies.

C. Ask the client to describe their support system: Exploring the client’s support system helps assess available emotional and practical resources. This information is essential in planning appropriate interventions and enhancing coping capacity.

D. Ask the client why they're unable to cope: "Why" questions can make clients feel defensive and judged. It is more therapeutic to use open-ended questions that invite sharing without implying blame.
