A nurse is reviewing the laboratory results of a client who has a pressure ulcer. The nurse should identify an elevation in which of the following laboratory values as an indication that the client has developed an infection?
RBC count
WBC count
Potassium
BUN
The Correct Answer is B
A. An elevation in the red blood cell (RBC) count is not a specific indication of infection. It primarily reflects oxygen-carrying capacity.
B. An elevation in the white blood cell (WBC) count is an indication of infection. When the body is fighting an infection, the number of white blood cells increases as part of the immune response.
C. Potassium is an electrolyte and is not a specific marker for infection. Abnormal potassium levels may indicate a variety of conditions, but they do not directly indicate infection.
D. Blood urea nitrogen (BUN) is a marker of kidney function and is not a specific indicator of infection. Elevated BUN levels can be seen in various kidney and non-kidney-related conditions.

Correct Answer is C
Explanation
A. Measuring the gastric residual is a common practice before administering enteral feedings. It helps to assess if the client's stomach is emptying properly and if there is any buildup of undigested formula. This is important in identifying delayed gastric emptying, which can lead to complications if not addressed.
B. To remove gastric acid that might cause dyspepsia is not the primary purpose of measuring gastric residual. The main concern is to assess the rate of stomach emptying.
C. To confirm the placement of the NG tube is typically done using other methods, such as pH testing or an X-ray. While aspirating stomach contents through the tube can help confirm placement, it is not the primary purpose of measuring gastric residual.
D. To determine the client's electrolyte balance is not related to the purpose of measuring gastric residual. Electrolyte balance is typically assessed through blood tests and clinical signs and symptoms.
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.
