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.

Answer and Explanation

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 A

Explanation

Choice A reason: Eating foods at room temperature can help reduce nausea because strong odors from hot foods can increase the feeling of nausea.

Choice B reason: Increasing unsaturated fats is not specifically related to managing nausea and may not be beneficial in this context.

Choice C reason: Drinking more liquids with meals can sometimes increase nausea; it's often recommended to drink fluids between meals instead.

Choice D reason: Eating smaller meals can help manage nausea because large meals can overwhelm the digestive system when it's sensitive due to treatment.

A. Chest tube eyelets not visible B. Development of subcutaneous emphysema C. Presence of tidal fluctuation in the water seal chamber D. Continuous bubbling in the suction control chamber

Correct Answer is B

Explanation

Choice A reason: The visibility of chest tube eyelets is not typically a concern unless there is evidence that the tube is dislodged. In normal circumstances, the eyelets may not be visible, and this does not necessarily indicate a need for intervention.

Choice B reason: The development of subcutaneous emphysema, which is the presence of air in the subcutaneous tissue, can be a sign of a serious complication such as a pneumothorax. It requires immediate assessment and possible intervention to prevent further complications.

Choice C reason: Tidal fluctuation in the water seal chamber is a normal finding when a chest tube is in place. It indicates that the system is patent and functioning correctly as it reflects the pressure changes in the pleural space during respiration.

Choice D reason: Continuous bubbling in the suction control chamber may indicate an air leak in the system, which could be normal if the system is set to continuous suction. However, if the bubbling is vigorous and the system is not set to continuous suction, it may indicate a new air leak and require intervention.
