A nurse is caring for a client who has a wound infection. Which of the following actions should the nurse take when obtaining a wound-drainage specimen for culture?

Irrigate the wound with an antiseptic prior to obtaining the specimen.

Include intact skin at the wound edges in the culture.

Swab an area of skin away from the wound to identify the usual flora.

Cleanse the wound with 0.9% sodium chloride saline irrigation before obtaining the specimen.

Answer and Explanation

The Correct Answer is D

A.   Irrigating the wound with an antiseptic prior to obtaining the specimen can introduce substances that may interfere with the accuracy of the culture results. Sterile saline is the preferred solution for wound irrigation.
B.   Intact skin at the wound edges should not be included in the culture. The specimen should be obtained directly from the wound bed or drainage.
C.   Swabbing an area of skin away from the wound to identify the usual flora is not appropriate for obtaining a wound drainage specimen. The culture should be taken directly from the wound site.
D.   Before obtaining a wound-drainage specimen for culture, it is important to cleanse the wound with a sterile solution, such as 0.9% sodium chloride saline irrigation. This helps remove debris and contaminants from the wound site, providing a more accurate specimen for culture.

Correct Answer is C

Explanation

A. Observing the client's respiratory status is also important, but it is an ongoing assessment rather than an immediate action.

B. Monitoring intake and output every 8 hours is important for overall fluid balance, but it is not the top priority in this situation.

C. This is crucial to prevent aspiration, which can occur if the feeding formula enters the lungs, leading to pneumonia or other serious complications. Elevating the head of the bed helps keep the esophagus above the stomach, reducing the risk of aspiration.

D. Checking residual volume every 4 to 6 hours is a part of enteral feeding care, but it is not the top priority. Monitoring respiratory status takes precedence due to the potential risk of aspiration.

A. Hypertension and crackles B. Fever and chills C. Excessive thirst and urination D. Shakiness and diaphoresis

Correct Answer is D

Explanation

a. Hypertension and crackles:

While hypertension can be associated with various conditions, such as cardiovascular diseases or stress, it is not directly related to the cessation of TPN infusion.

Crackles in the lungs are often indicative of fluid accumulation or inflammation, commonly seen in conditions like pneumonia or heart failure. They are not typically associated with the interruption of TPN infusion.

b. Fever and chills:

Fever and chills can be symptoms of infection or inflammatory processes in the body. However, they are not specifically related to the interruption of TPN infusion.

In the context of TPN cessation, the focus would be on metabolic changes rather than infectious processes.

c. Excessive thirst and urination:

Excessive thirst and urination are classic symptoms of hyperglycemia, which can occur when TPN, particularly if it contains a high glucose concentration, is abruptly interrupted.

When TPN infusion stops, there is no longer a continuous supply of glucose to the body, leading to increased blood glucose levels and subsequent polyuria (excessive urination) and polydipsia (excessive thirst) as the body tries to eliminate excess glucose.

d. Shakiness and diaphoresis:

Shakiness and diaphoresis (excessive sweating) are classic symptoms of hypoglycemia, which can occur if TPN, particularly if it contains a high concentration of insulin, is abruptly interrupted.

TPN solutions often contain glucose and insulin to maintain proper blood glucose levels. If the infusion is stopped suddenly, there may be a rapid decline in blood glucose levels, leading to hypoglycemia, which manifests as shakiness, diaphoresis, confusion, and other neuroglycopenic symptoms.
