A nurse is attending to a patient with a wound infection.
What should the nurse do when collecting a wound-drainage specimen for culture?
Swab an area of skin away from the wound to identify the usual flora.
Irrigate the wound with an antiseptic prior to obtaining the specimen.
Cleanse the wound with 0.9% sodium chloride saline irrigation before obtaining the specimen.
Include intact skin at the wound edges in the culture.
The Correct Answer is C
Choice A rationale
Swabbing an area of skin away from the wound to identify the usual flora is not the correct action. This would not provide a representative sample of the wound infection.
Choice B rationale
Irrigating the wound with an antiseptic prior to obtaining the specimen is not the correct action. This could potentially alter the results of the culture.
Choice C rationale
Cleansing the wound with 0.9% sodium chloride saline irrigation before obtaining the specimen is the correct action. This helps to remove surface bacteria and ensures a more accurate culture result.
Choice D rationale
Including intact skin at the wound edges in the culture is not the correct action. This could contaminate the specimen with bacteria that are not part of the wound infection.

Correct Answer is ["B","C","E"]
Explanation
Choice A rationale
Albuterol does not directly decrease coughing episodes. Coughing can be a symptom of an underlying condition like asthma, which albuterol can help manage by relaxing the muscles around the airways. However, the medication itself does not have a direct effect on coughing.
Choice B rationale
Albuterol helps prevent wheezing by relaxing the muscles around the airways, allowing them to open up and making it easier to breathe. Wheezing is a common symptom of conditions like asthma, which albuterol is often used to treat.
Choice C rationale
Albuterol works by opening the airways of the lungs, making it easier to breathe. It does this by relaxing the muscles around the airways, allowing more air to flow into the lungs.
Choice D rationale
Albuterol does not stimulate the flow of mucus. While it can help manage symptoms of conditions like asthma, it does not have a direct effect on mucus production.
Choice E rationale
Albuterol does not directly reduce inflammation. It works by relaxing the muscles around the airways, which can help alleviate symptoms of conditions characterized by inflammation, such as asthma. However, the medication itself does not have anti-inflammatory properties.
Correct Answer is D
Explanation
Choice A rationale
After a total laryngectomy, patients may have difficulty swallowing fluids due to changes in the anatomy of the throat.
Choice B rationale
It is not accurate to say that it is no longer possible for the patient to choke on or aspirate food after a total laryngectomy. While the risk of aspiration is reduced because the airway and digestive tract are separated, the patient can still experience choking on food if it is not properly swallowed.
Choice C rationale
Adding a thickener to liquids can help prevent aspiration, but this is typically more relevant for patients with dysphagia or other swallowing disorders, not specifically for patients post- laryngectomy.
Choice D rationale
Tucking the chin when swallowing, also known as the chin-tuck maneuver, can help prevent aspiration by narrowing the entrance to the airway. This can be a useful technique for patients after a laryngectomy.
