A man has been admitted to the hospital unit with a medical diagnosis of chronic obstructive pulmonary disease (COPD). He is receiving supplemental oxygen at 2 L/min via a nasal cannula. Which positioning technique will best assist him with breathing?

Choice A reason: Wearing a gown is the correct answer, because it is the appropriate PPE for contact precautions, which are required for clients who have MRSA. MRSA is a type of bacteria that is resistant to many antibiotics and can cause serious infections in the skin, blood, lungs, or other organs. MRSA can be transmitted by direct or indirect contact with the infected wound or contaminated surfaces. Wearing a gown can protect the nurse's clothing and skin from exposure to MRSA.

Choice B reason: Wearing sterile gloves is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. Sterile gloves are used for sterile procedures, such as inserting a catheter or changing a dressing, not for routine assessments, such as checking the pulse. Wearing sterile gloves can be wasteful and unnecessary, and it does not provide adequate protection from MRSA.

Choice C reason: Wearing a PAPR mask is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. PAPR stands for powered airpurifying respirator, and it is a type of mask that filters the air and provides positive pressure to the wearer. PAPR masks are used for airborne precautions, which are required for clients who have diseases that can be spread through the air, such as tuberculosis or measles, not for clients who have MRSA.

Choice D reason: Wearing a surgical mask is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. Surgical masks are used for droplet precautions, which are required for clients who have diseases that can be spread through respiratory droplets, such as influenza or pertussis, not for clients who have MRSA.

Choice A reason: This is not the best action because encouraging range of motion can worsen the symptoms and cause more damage to the nerves and blood vessels. Range of motion is the movement of the joints and muscles through their normal extent. Range of motion can help to prevent stiffness, contractures, and muscle atrophy, but it can also increase the swelling and pressure in the affected area, which can impair the circulation and sensation.

Choice B reason: This is not the best action because applying heat to the affected hand can worsen the symptoms and cause more damage to the tissues. Heat is the transfer of thermal energy from a warmer object to a cooler one. Heat can help to relax the muscles, reduce the pain, and increase the blood flow, but it can also increase the inflammation and edema in the affected area, which can compromise the oxygen and nutrient delivery to the tissues.

Choice C reason: This is the best action because removing the cast can decrease the pressure and restore the circulation and sensation to the affected area. A cast is a rigid device that immobilizes and protects a fractured or injured body part. A cast can help to align the bones, prevent displacement, and promote healing, but it can also cause complications, such as compartment syndrome, infection, or nerve damage. Compartment syndrome is a condition where the pressure inside the muscles increases to dangerous levels, causing severe pain, reduced blood flow, and tissue death. The nurse should remove the cast immediately and notify the physician if the client shows signs of compartment syndrome, such as numbness, tingling, pallor, coolness, or swelling.

Choice D reason: This is not the best action because raising the arm above the level of the heart can worsen the symptoms and cause more damage to the nerves and blood vessels. Raising the arm above the level of the heart can help to reduce the swelling and pain in the affected area, but it can also reduce the blood flow and oxygenation to the area, which can lead to ischemia, necrosis, or gangrene. The nurse should elevate the arm at or below the level of the heart and monitor the pulse, color, temperature, and sensation of the fingers.
