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 B
Explanation
Choice A reason: Respiratory Alkalosis Partially Compensated is characterized by an elevated pH over 7.45 and a PaCO2 under 35 mmHg, with a compensatory acidic HCO3 under 22 mEq/L. This does not match the patient's ABG results.
Choice B reason: Respiratory Acidosis Uncompensated is indicated by an acidic pH under 7.35 and an elevated PaCO2 over 45 mmHg, with HCO3 in the normal range of 2226 mEq/L. The patient's ABG results show a low pH and high PaCO2, which aligns with this condition.
Choice C reason: Metabolic Alkalosis Partially Compensated would show a basic pH over 7.45 and a basic HCO3 over 26 mEq/L, with a compensatory acidic PaCO2 over 45 mmHg[^10^]. The patient's ABG values do not support this diagnosis.
Choice D reason: Metabolic Acidosis Uncompensated would present with an acidic pH under 7.35 and an acidic HCO3 under 22 mEq/L, with PaCO2 in the normal range of 3545 mmHg⁸. The patient's normal HCO3 level does not indicate metabolic acidosis.
Correct Answer is B
Explanation
Choice A reason: Asking about multivitamin intake is not directly relevant to GBS, as the syndrome is not known to be caused by vitamin deficiencies or related to nutritional status.
Choice B reason: A recent influenza infection is relevant because GBS is often preceded by an infection, such as a respiratory or gastrointestinal viral infection. The immune system's response to this infection may mistakenly attack peripheral nerves, leading to GBS.
Choice C reason: While travel history is important in assessing exposure to infectious diseases, it is less specific than asking about recent infections. GBS can occur after exposure to certain viruses or bacteria, which can be contracted without overseas travel.
Choice D reason: Chronic alcohol abuse is a risk factor for various neurological conditions, but it is not a typical precursor to GBS. The syndrome is more commonly associated with immune responses to infections.
