While changing a client’s postoperative dressing, the nurse observes purulent drainage at the wound. Before reporting this finding to the healthcare provider, the nurse should note which of the client’s laboratory values?

A.

Serum blood glucose level.

B.

Culture for sensitive organisms.

C.

C-reactive protein level.

D.

Blood pH level.

Answer and Explanation

The Correct Answer is B

Choice A rationale

 

Serum blood glucose level is not directly related to the presence of purulent drainage at a wound site. While blood glucose levels can affect wound healing, they do not provide specific information about the presence of infection.

 

Choice B rationale

 

Culture for sensitive organisms is the most appropriate laboratory value to note when purulent drainage is observed. This test helps identify the specific bacteria causing the infection and determines the most effective antibiotics for treatment.

 

Choice C rationale

 

C-reactive protein (CRP) level is a marker of inflammation and can indicate the presence of an infection, but it does not provide specific information about the bacteria causing the infection.

 

Choice D rationale

 

Blood pH level is not directly related to the presence of purulent drainage at a wound site. While blood pH can be affected by severe infections, it is not a specific indicator of wound infection.

Correct Answer is C

Explanation

Choice A rationale

Palpating large joints for nodules is not the most effective technique for assessing early signs of rheumatoid arthritis (RA). Nodules typically appear in more advanced stages of RA and are not an early sign.

Choice B rationale

Observing the skin for lesions is not specific to RA. While skin lesions can be associated with other conditions, they are not a primary indicator of early RA1.

Choice C rationale

Observing the client’s fingers is crucial for detecting early signs of RA. Early RA often presents with swelling, tenderness, and stiffness in the small joints of the fingers.

Choice D rationale

Palpating the lymph nodes is not relevant for early RA assessment. Lymph node enlargement is not a typical early sign of RA1.
