In preparing to discontinue a client's saline lock, the practical nurse (PN) notes that the client is receiving an antiplatelet medication. Which action should the PN implement?

A. C-reactive protein level:
C-reactive protein (CRP) is a marker of inflammation but does not specifically identify the causative organism of an infection. While elevated CRP can suggest infection or inflammation, it doesn't provide the necessary information for treatment.

B. Serum blood glucose (BG) level:
Serum blood glucose levels are important to monitor in diabetic patients because high glucose levels can impair healing and increase the risk of infection. However, it does not directly help identify the causative organism in this situation.

C. Serum albumin:
Serum albumin reflects nutritional status and can indicate malnutrition or poor wound healing. While it may be relevant for healing, it is not the most immediate test to evaluate for infection.

D. Culture for sensitive organisms:
Given the red, swollen wound with drainage and foul odor, a wound culture is the most appropriate first step to identify the specific infectious organism. This will guide the healthcare provider in selecting the most appropriate antibiotic treatment.

In cases of suspected child abuse, inconsistencies or discrepancies between the child's account of the injury and the caregiver's version are concerning. It raises questions about the credibility of the explanation provided by the caregiver and suggests a possible attempt to conceal the true cause of the injury. Such discrepancies may indicate that the injury was intentionally inflicted or that the child is being coerced or influenced to provide a false account.
While the other assessment findings may raise some level of concern, they are not as significant as the discrepancy between the child's and mother's versions of the injury:
A. "The mother refuses to answer questions about family history." While this behavior may raise some suspicion or cause for further investigation, it alone does not conclusively indicate child abuse. It may be related to other factors such as privacy concerns or cultural differences.
B. "The child has several abrasions on the chest and legs." While the presence of abrasions can be concerning, they alone do not provide sufficient evidence of child abuse. Children are prone to injuries and can obtain abrasions during normal play and activities.
C. "The child looks at the floor when answering the nurse's questions." This behavior may suggest shyness, anxiety, or discomfort, but it is not a definitive indicator of child abuse. Some children may exhibit such behaviors due to their personality or other factors unrelated to abuse. It is important to consider the child's overall behavior and communication patterns in conjunction with other assessment findings.
