The healthcare provider prescribes cefazolin 500 mg IM every 6 hours. The available vial is labeled, "Cefazolin 1 gram,”. and the instructions for reconstitution state, "For IM use, add 2.5 mL sterile water for injection to provide a total volume of 3.0 mL.”. After reconstitution, how many mL should be administered to the client? (Enter numeric value only. If rounding is required, round to the nearest tenth.).
The Correct Answer is ["1.5"]
Step 1: 1 gram = 1000 mg
Step 2: 500 mg ÷ 1000 mg = 0.5
Step 3: 0.5 × 3.0 mL = 1.5 mL

Correct Answer is B
Explanation
The PN should not prioritize bringing a glucometer to the room in this situation. The client's unresponsiveness indicates a potential medical emergency that requires immediate action, and checking blood glucose levels is not the primary concern at this moment.
Choice C rationale:
Feeling for a carotid pulse is an essential step in assessing the client's circulation. However, it is not the first priority when the client is unresponsive. The PN should focus on obtaining emergency help first to ensure timely intervention.
Choice D rationale:
Checking the blood pressure can provide valuable information about the client's condition, but it is not the most critical step when dealing with an unresponsive client. Promptly seeking emergency assistance is more important to address the immediate concern.
Correct Answer is D
Explanation
The correct answer is choice D. Don non-sterile gloves when performing direct care.
Choice A rationale:
Placing a surgical mask on the client during transport is not necessary for preventing the spread of Clostridium difficile. C. difficile is primarily spread through contact with contaminated surfaces and not through airborne transmission.
Choice B rationale:
Keeping the door closed to the client’s room at all times is not required for C. difficile infection. The focus should be on contact precautions rather than airborne precautions.
Choice C rationale:
Wearing a particulate respirator mask is not needed for C. difficile, as it is not an airborne pathogen. Standard contact precautions are sufficient.
Choice D rationale:
Donning non-sterile gloves when performing direct care is essential to prevent the spread of C. difficile. The spores can be transmitted via the hands of healthcare workers, so wearing gloves helps to minimize this risk.
