A nurse is educating a community group about infection control and prevention. Which of the following should the nurse include as an example of vector-borne transmission?

A. A client who has a history of MRSA will need antibiotics: Not all clients with a history of MRSA require antibiotics; treatment is only necessary if there is an active infection. Prophylactic antibiotics are not indicated solely based on past MRSA colonization or infection.

B. A client who has a history of MRSA can develop immunity to the infection: There is no immunity conferred by a past MRSA infection. Clients can be colonized or reinfected, and immunity does not prevent future transmission or infection.

C. A client who has a history of MRSA requires a protective environment: Protective environment precautions are used for immunocompromised clients to prevent them from acquiring infections, not for clients with MRSA history. MRSA requires standard and contact precautions, not protective isolation.

D. A client who has a history of MRSA can still transmit the infection: Clients with a history of MRSA may remain colonized and can transmit the bacteria to others, even if asymptomatic. Adhering to contact precautions and proper hand hygiene is essential to prevent spread within healthcare settings.

A. Atropine 4 mg IV stat: The dose of atropine is unusually high for typical adult administration, and documentation should include accurate dosing units and safety checks. Such a dose may indicate a potential medication error or require verification before administration.

B. Lorazepam 1.0 mg IV PRN every 6 hr: Using a trailing zero (1.0 mg) is unsafe because it can be misread as 10 mg, leading to overdose. Proper documentation avoids trailing zeros (e.g., 1 mg) and follows safe medication guidelines.

C. Sucralfate 1 g PO 1 hr ac: While the dose may be appropriate, abbreviations such as "ac" should be written out as "before meals" to prevent misinterpretation. Clear, unambiguous documentation is required for safe administration.

D. Enoxaparin 30 mg SC every 12 hr: This prescription uses correct dosing, route, frequency, and documentation format. It is clear, safe, and follows standard guidelines, making it the correct example of proper documentation.
