A nurse in an emergency department is caring for a patient with a deep laceration on his left lower forearm. After observing standard precautions, which of the following actions should the nurse take?
Apply a tourniquet just below the elbow.
Elevate the limb and apply ice.
Clean the wound.
Apply pressure above the wound.
The Correct Answer is B
Choice A reason: Applying a tourniquet just below the elbow is not recommended as the first line of action for a deep laceration unless there is life-threatening hemorrhaging that cannot be controlled by direct pressure. Tourniquets are used as a last resort because they can cause tissue damage.
Choice B reason: Elevating the limb and applying ice can help reduce bleeding and swelling. Elevation uses gravity to help reduce blood flow to the injury, and the cold from the ice constricts blood vessels, further helping to control bleeding and reduce swelling.
Choice C reason: Cleaning the wound is important, but it should not be the first action taken. The initial focus should be on stopping the bleeding. Once bleeding is controlled, the wound can be cleaned to prevent infection.
Choice D reason: Applying pressure directly to the wound with a clean cloth or bandage is the first step in controlling bleeding. However, the question specifies applying pressure above the wound, which would not be effective in controlling bleeding from the wound itself.

Correct Answer is C
Explanation
Choice A reason: This choice is incorrect. Painless, raised purple nodules on the hard palate are not typically indicative of squamous cell carcinoma.
Choice B reason: This choice is incorrect. A small macule with a yellow-brown scale does not describe squamous cell carcinoma, which often presents as a firm nodule with a scaly crust.
Choice C reason: This is the correct choice. Squamous cell carcinoma can present as a firm nodule with a hard, scaly crust on the skin.
Choice D reason: Yellow white patches of growth on the tongue are more indicative of conditions such as oral leukoplakia, not squamous cell carcinoma.
Correct Answer is B
Explanation
Choice A reason: Tennis involves abrupt lateral movements and may not be suitable for someone with low back pain, as it can exacerbate the condition.
Choice B reason: Swimming is a low impact exercise that can help strengthen the back muscles without putting additional stress on the spine, making it an ideal choice for individuals with low back pain.
Choice C reason: The option "Custom: NUR 224G Sec 2 Blandon Final" does not refer to a specific exercise and seems to be an error or unrelated text.
Choice D reason: Rowing can be strenuous on the lower back due to the repetitive motion and the need for strong core engagement, which might not be recommended for acute low back pain.
