A nurse is serving on a committee that is developing infectious disease protocols. Which of the following instructions should the nurse include in the protocol for clients who have Clostridium difficile?
Disinfect hands using an alcohol-based waterless antiseptic.
Wear an N95 respirator when caring for the client.
Use diluted bleach to clean solled equipment.
Provide a room with negative-pressure airflow.
The Correct Answer is C
A. Disinfecting hands using an alcohol-based waterless antiseptic is not effective against Clostridium difficile spores. C. difficile is a bacterium that forms spores, which are resistant to alcohol-based hand sanitizers. Handwashing with soap and water is recommended for effective removal of the spores.
B. Wearing an N95 respirator is not specifically indicated for caring for clients with Clostridium difficile. The primary mode of transmission for C. difficile is fecal-oral, and standard precautions, including gloves and gowns, are usually sufficient. N95 respirators are more commonly used for airborne precautions.
C. Using diluted bleach to clean soiled equipment is the correct instruction. Clostridium difficile spores are resistant to many disinfectants, but bleach (sodium hypochlorite) is effective in killing C. difficile spores. Diluted bleach solutions are recommended for cleaning surfaces and equipment that may be contaminated with C. difficile.
D. Providing a room with negative-pressure airflow is not typically necessary for clients with Clostridium difficile. Standard precautions, including appropriate cleaning and disinfection, are generally sufficient to prevent the spread of C. difficile in healthcare settings.

Correct Answer is A
Explanation
A. Discard any remaining medication after 10 days:
This is the correct action according to the label. The label specifies that the reconstituted suspension should be discarded after 10 days, emphasizing the importance of not using the medication beyond that period for safety reasons.
B. Use 0.9% sodium chloride solution as a diluent:
The label does not mention the use of 0.9% sodium chloride solution. It specifically provides directions for adding water for reconstitution. Therefore, using sodium chloride solution is not consistent with the instructions.
C. Roll the vial gently in hands to mix the medication:
The label instructs to "Shake vigorously" to wet the powder, not to roll it gently. Shaking is the recommended method for mixing the medication according to the label.
D.Store the medication at room temperature following reconstitution:
The label clearly states that the reconstituted suspension "Must be refrigerated." Storing it at room temperature contradicts the provided instructions
Correct Answer is ["0.7"]
Explanation
To calculate the volume (mL) that the nurse should administer, we can follow these steps:
Convert the weight from pounds to kilograms.
1 lb=0.453592 kg.
66 lb×0.453592 kg/lb≈29.937 kg
Calculate the total dose using the weight and prescribed dose:
Total Dose (mg)=Dose per kg×Weight (kg)
Total Dose=0.55 mg/kg×29.937 kg≈16.465 mg
Determine the volume using the concentration of the available solution:
Volume (mL) =Total Dose (mg)/Concentration (mg/mL)
Volume=16.465mg/25 mg/mL≈ 0.6586 mL
Therefore, the nurse should administer approximately 0.7 mL of chlorpromazine for the 0.55 mg/kg IM dose, rounded to the nearest tenth.
