The nurse is caring for a client who develops compartment syndrome from a severely fractured arm. The client asks the nurse why this can happen. What is the best response by the nurse?
A bone fragment has injured the nerve supply in the area.
An injured artery causes impaired arterial perfusion through the compartment.
Bleeding and swelling cause increased pressure in an area that cannot expand.
The fascia expands with injury, causing pressure on underlying nerves and muscles.
The Correct Answer is C
Choice A reason: A bone fragment has injured the nerve supply in the area is not the best response by the nurse. This may be a possible complication of a fracture, but it does not explain the mechanism of compartment syndrome. Compartment syndrome is a condition where the pressure within a closed space (such as a muscle compartment) exceeds the perfusion pressure and causes ischemia and necrosis of the tissues. A bone fragment may damage the nerve, but it does not cause increased pressure in the compartment.
Choice B reason: An injured artery causes impaired arterial perfusion through the compartment is not the best response by the nurse. This may be a possible cause of compartment syndrome, but it is not the most common one. Compartment syndrome is more often caused by venous obstruction than arterial obstruction. An injured artery may reduce the blood flow to the compartment, but it does not cause increased pressure in the compartment.
Choice C reason: Bleeding and swelling cause increased pressure in an area that cannot expand is the best response by the nurse. This is the most common cause of compartment syndrome and explains the pathophysiology of the condition. Bleeding and swelling are the result of inflammation and tissue injury that occur after a fracture. They increase the volume of fluid in the compartment, which cannot expand due to the rigid fascia that surrounds it. This leads to increased pressure in the compartment, which compresses the blood vessels, nerves, and muscles and causes ischemia and necrosis of the tissues.
Choice D reason: The fascia expands with injury, causing pressure on underlying nerves and muscles is not the best response by the nurse. This is not a correct statement, as the fascia does not expand with injury. The fascia is a tough connective tissue that encloses the muscle compartments and limits their expansion. The fascia is part of the problem, not the cause, of compartment syndrome. The fascia prevents the compartment from accommodating the increased volume of fluid and causes increased pressure in the compartment.

Correct Answer is D
Explanation
Choice A reason: Use gentle brushing and flossing techniques for clients with fragile mucosa is an important nursing intervention, but it is not the priority. Gentle brushing and flossing can help prevent plaque, gingivitis, and infection in the oral cavity, especially for clients with fragile mucosa due to dehydration, medication, or radiation. However, this intervention is not as urgent as having a suction apparatus ready at the bedside.
Choice B reason: Handle dentures with care is an important nursing intervention, but it is not the priority. Handling dentures with care can prevent damage, loss, or misplacement of the dentures, which can affect the client's comfort, appearance, and nutrition. However, this intervention is not as urgent as having a suction apparatus ready at the bedside.
Choice C reason: Position the client on one side with the head turned towards you is an important nursing intervention, but it is not the priority. Positioning the client on one side with the head turned towards you can facilitate the access and visibility of the oral cavity, as well as prevent the aspiration of saliva, blood, or debris. However, this intervention is not as effective as having a suction apparatus ready at the bedside.
Choice D reason: Have a suction apparatus ready at the bedside is the priority nursing intervention, because it can prevent the aspiration of saliva, blood, or debris, which can cause choking, pneumonia, or respiratory distress. Having a suction apparatus ready at the bedside can allow the nurse to quickly and safely remove any secretions or foreign materials from the oral cavity or the airway of the unconscious client.
Correct Answer is B
Explanation
Choice A reason: "I will use a humidifier during the winter months." is not the correct answer, because it indicates a good understanding of dry skin. Using a humidifier during the winter months is a helpful measure to prevent or treat dry skin, as it can increase the moisture level in the air, which can hydrate the skin and reduce the loss of natural oils.
Choice B reason: "I will shower every day in hot water." is the correct answer, because it indicates a need for further teaching about dry skin. Showering every day in hot water is a harmful practice that can worsen dry skin, as it can strip the skin of its natural oils, damage the skin barrier, and cause irritation and inflammation.
Choice C reason: "I will avoid tight belts." is not the correct answer, because it indicates a good understanding of dry skin. Avoiding tight belts is a helpful measure to prevent or treat dry skin, as it can reduce the friction and pressure on the skin, which can prevent skin breakdown and infection.
Choice D reason: "I will drink at least 3000 mL of water daily." is not the correct answer, because it indicates a good understanding of dry skin. Drinking at least 3000 mL of water daily is a helpful measure to prevent or treat dry skin, as it can hydrate the body and the skin, and flush out toxins and waste products.
