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: Dehydration is a concern with fever, but it is not a direct complication of hypothermia blanket therapy. It is important to ensure adequate hydration, but the primary concern with hypothermia therapy is not dehydration.
Choice B reason: Burns could occur if the hypothermia blanket malfunctions or is used improperly. However, modern devices have safety features to prevent burns, making this a less likely complication.
Choice C reason: Shivering is a natural response to cooling and can occur as the body attempts to generate heat in response to the lowered temperature from the hypothermia blanket. It can be counterproductive to the therapy and may need to be controlled with medications.
Choice D reason: Seizures are not a typical complication of hypothermia blanket therapy. While meningitis can cause seizures due to inflammation of the brain, the hypothermia blanket itself does not induce seizures.
Correct Answer is ["A","B","D"]
Explanation
Choice A reason: Blowing the nose gently is advised to prevent nosebleeds, which can be a risk due to thrombocytopenia.
Choice B reason: Lubricating lips with water-soluble ointment can prevent cracking and bleeding, which is important for a patient with thrombocytopenia.
Choice C reason: Using a straightedge razor is not recommended because it can increase the risk of cuts and bleeding. An electric razor would be safer.
Choice D reason: Brushing teeth with a soft toothbrush is recommended to prevent gum bleeding due to the low platelet count associated with thrombocytopenia.
Choice E reason: Limiting fruit consumption is not necessary for thrombocytopenia unless the patient has a specific condition that requires dietary restrictions.
