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

Answer and Explanation

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.

Explanation

A. The right upper sternal border is not the correct placement for auscultating the apical pulse. This location is more appropriate for assessing heart sounds related to the aortic valve.
B. The left upper sternal border is not the correct placement for auscultating the apical pulse.
This location is more appropriate for assessing heart sounds related to the pulmonic valve.
C. The left lower sternal border is not the correct placement for auscultating the apical pulse.
This location is more appropriate for assessing heart sounds related to the tricuspid valve.
D. 5th intercostal space, midclavicular line is the correct placement for auscultating the apical pulse. This location corresponds to the apex of the heart, which is where the apical pulse (also known as the point of maximum impulse or PMI) can be best heard.
