A nurse is obtaining a specimen for a wound culture from a client. Which of the following actions should the nurse take?

Rotate the swab over necrotic tissue.

Obtain the sample from the outer edge of the wound.

Apply sterile gloves to remove the outer dressing.

Crush the transport medium after obtaining the specimen.

Answer and Explanation

The Correct Answer is C

c. Apply sterile gloves to remove the outer dressing.

Choice A Reason:

Rotating the swab over necrotic tissue is not recommended because necrotic tissue does not provide an accurate representation of the microorganisms present in the wound. Necrotic tissue is dead tissue, and culturing it can lead to misleading results, as it may not reflect the current state of infection or the microorganisms causing the infection.

Choice B Reason:

Obtaining the sample from the outer edge of the wound is also not ideal. The outer edge of the wound may be contaminated with skin flora or other external contaminants, which can lead to inaccurate culture results. The sample should be taken from clean, viable tissue within the wound bed to ensure accurate identification of the microorganisms present.

Choice C Reason:

Applying sterile gloves to remove the outer dressing is the correct action. This step is crucial to maintain aseptic technique and prevent contamination of the wound and the specimen. Sterile gloves help ensure that the nurse does not introduce any external microorganisms into the wound while handling the dressing.

Choice D Reason:

Crushing the transport medium after obtaining the specimen is a necessary step to activate the medium and preserve the specimen during transport to the laboratory. However, this step comes after the specimen has been collected and does not directly relate to the technique of obtaining the specimen.

Correct Answer is A

Explanation

Choice A Reason:

Airborne precautions are necessary for clients with tuberculosis (TB) because TB is an airborne disease. It is transmitted through tiny droplets released into the air when an infected person coughs, sneezes, or talks. These precautions include placing the client in a negative pressure room, using N95 respirators for healthcare workers, and ensuring the client wears a surgical mask when outside their room. These measures help prevent the spread of TB to others.

Choice B Reason:

Protective precautions, also known as reverse isolation, are used to protect immunocompromised patients from infections. These precautions are not appropriate for a client with TB, as the primary concern is preventing the spread of TB from the infected client to others, not protecting the client from external infections.

Choice C Reason:

Contact precautions are used for infections that are spread by direct or indirect contact with the patient or their environment, such as MRSA or C. difficile. TB is not spread through contact but through airborne particles, so contact precautions are not sufficient for preventing the transmission of TB.

Choice D Reason:

Droplet precautions are used for diseases that are spread through large respiratory droplets, such as influenza or pertussis. While TB is a respiratory disease, it is spread through much smaller airborne particles that can remain suspended in the air for longer periods, making airborne precautions necessary instead of droplet precautions.

A. Instruct the client to take deep, rhythmic breaths. B. Encourage the client to apply a heating pad for 2 hours at a time. C. Apply an ice pack to the client’s back for 1 hour. D. Remove distractions from the client’s room.

Correct Answer is C

Explanation

Choice A Reason:

Instructing the client to take deep, rhythmic breaths can help in managing pain by promoting relaxation and reducing muscle tension. Deep breathing exercises are a common nonpharmacological intervention for pain relief. However, for localized back pain, this method might not be as effective as applying an ice pack directly to the affected area.

Choice B Reason:

Encouraging the client to apply a heating pad for 2 hours at a time can provide relief by increasing blood flow and relaxing muscles. However, prolonged use of heat can sometimes exacerbate inflammation, especially if the pain is due to an acute injury. Therefore, it is generally recommended to alternate between heat and cold therapy.

Choice C Reason:

Applying an ice pack to the client’s back for 1 hour is effective in reducing inflammation and numbing the pain. Cold therapy is particularly useful in the initial stages of pain management as it helps to constrict blood vessels, reducing swelling and providing immediate pain relief. This method is often recommended for acute pain and injuries.

Choice D Reason:

Removing distractions from the client’s room can create a more restful environment, which may help in overall pain management. However, this action alone is unlikely to provide significant relief for localized back pain. It is more of a supportive measure rather than a primary intervention for pain relief.
