A client with paranoia is admitted to the mental health unit and immediately goes to the corner of the room and sits quietly without communicating. In approaching the client, what intervention should the practical nurse (PN) implement first?

Antiplatelet medications, such as aspirin or clopidogrel, are prescribed to prevent the formation of blood clots by inhibiting platelet aggregation. These medications can increase the risk of bleeding or prolonged bleeding time. Therefore, when removing the saline lock, applying pressure over the site for several minutes helps to minimize the risk of bleeding and promote hemostasis.
A. Leaving the saline lock in place and notifying the charge nurse may not be necessary unless there are specific concerns or complications related to the client's condition.
C. Encouraging the client to drink additional oral fluids is not directly related to the discontinuation of the saline lock and the potential risk of bleeding associated with antiplatelet medication.
D. Preparing a warm pack to apply after removing the lock is not necessary for this situation. Warm packs are typically used for comfort or to promote circulation, but they are not directly related to the risk of bleeding associated with antiplatelet medication.

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.
