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: Putting on nonsterile gloves is the first action that the nurse should take before performing a wound culture. This is to protect the nurse from exposure to blood and body fluids and to prevent crosscontamination. Nonsterile gloves are sufficient for wound care as long as the wound is not sterile or infected.

Choice B reason: Gently removing the soiled dressings is the second action that the nurse should take after putting on nonsterile gloves. This is to expose the wound and prepare it for irrigation and culture. The nurse should discard the soiled dressings in a biohazard bag and observe the wound for any signs of infection, such as redness, swelling, or odor.

Choice C reason: Irrigating the wound is the third action that the nurse should take after removing the soiled dressings. This is to cleanse the wound and remove any debris or bacteria. The nurse should use sterile normal saline or an antiseptic solution as prescribed by the provider and irrigate the wound with a syringe or a spray bottle. The nurse should avoid touching the wound with the irrigation device and collect the runoff in a basin or a towel.

Choice D reason: Labeling the specimen tube is the last action that the nurse should take after irrigating the wound and obtaining the culture. This is to ensure that the specimen is correctly identified and processed by the laboratory. The nurse should label the tube with the client's name, date, time, and site of the wound. The nurse should also document the procedure and the wound assessment in the client's chart.
