Correct Answer is C
Explanation
A. Ensure the client's environment is properly cleaned and disinfected is important, but the priority action is to prevent the spread of MRSA, which is highly contagious. Contact precautions should be initiated immediately to reduce the risk of transmission to others, including healthcare staff and visitors.
B. Reapply sterile non-adhesive dressing is necessary for wound care, but it is not the most important action in this scenario. Ensuring the appropriate precautions are taken to prevent the spread of MRSA is the priority.
C. Initiate contact precautions is the most important action. MRSA is a highly contagious bacterial infection that can spread easily through contact with contaminated surfaces or individuals. By initiating contact precautions, the nurse helps to protect other patients, staff, and visitors from exposure to MRSA.
D. Teach family members how to prevent transmission of infection is important but should be done after the immediate infection control measures, such as initiating contact precautions, have been implemented. Family education can occur once the proper isolation procedures are in place.
Correct Answer is C
Explanation
A. Withhold the medication until the exact dose is available is not the best first action. The nurse should first report the discrepancy to ensure that the prescribed dose is correct and to confirm if the medication should be withheld or adjusted.
B. Calculate the dose on hand to match the prescribed dose is not appropriate. The nurse should not attempt to adjust the medication dose without confirmation from the healthcare provider or pharmacist.
C. Report a mismatch of prescribed and available doses is the correct action. The nurse should immediately report the discrepancy to the pharmacist or healthcare provider to verify the correct dose and prevent potential harm to the client.
D. Ask the pharmacist if another dose can be dispensed is an appropriate follow-up action but is secondary to reporting the mismatch first. The nurse needs to clarify the prescription and dosage before taking further steps.
