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 D

Explanation

A. Mark the length to be inserted on the tube with tape: Marking the insertion length is important to ensure correct placement, but this step should occur after assessing which nare to use and preparing the client.

B. Instruct the client to hyperextend her neck: Hyperextending the neck is not recommended during NG tube insertion; instead, the client should slightly flex the neck to facilitate tube passage.

C. Place a water-based lubricant on the tip of the tube: Lubricating the tube reduces discomfort and eases insertion, but this step comes after selecting the nostril and preparing the client.

D. Compare the patency of the client’s nares: Assessing which nostril is more patent is the first priority to ensure the tube is inserted through the nare that offers the least resistance, reducing trauma and improving comfort during insertion.

A. The client holds the cane on the stronger side of their body. B. The client advances the cane forward 12.7 cm (5 in). C. The client moves their stronger leg forward first. D. The top of the cane is at the same height as the client's waist.

Correct Answer is A

Explanation

A. The client holds the cane on the stronger side of their body: Holding the cane on the stronger side improves balance and support while reducing strain on the weaker limb. It also helps coordinate movement and distribute weight more efficiently during ambulation.

B. The client advances the cane forward 12.7 cm (5 in): The cane should typically be advanced 15 to 25 cm (6 to 10 inches) forward for optimal support. Advancing it only 5 inches may provide insufficient balance assistance during walking.

C. The client moves their stronger leg forward first: The weaker leg should move forward after the cane to allow the stronger leg to support most of the weight. This pattern maximizes stability and safety during ambulation.

D. The top of the cane is at the same height as the client's waist: The cane should be level with the wrist crease when the client’s arms are relaxed at their sides, not at waist level. A cane that is too high or low can cause discomfort or improper posture.
