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

Correct Answer is ["B","D"]
Explanation
The correct answers are Choice B and D:
Choice B: Report the appearance of the dressing to the charge nurse,
Choice D: Compress the drainage device before closing the tab.
Choice A rationale:
Documenting the appearance of the wound as inflamed is not appropriate. As a practical nurse, the immediate concern is to take action and report any concerning findings to the appropriate healthcare provider rather than just documenting it.
Choice B rationale:
Reporting the appearance of the dressing to the charge nurse is essential. The charge nurse or a more experienced healthcare provider needs to be informed of any abnormal findings or signs of infection for further evaluation and appropriate intervention.
Choice C rationale:
Removing the drainage device and applying a pressure dressing is not within the scope of practice for a practical nurse. These actions require a higher level of expertise and are typically performed by a registered nurse or healthcare provider.
Choice D rationale:
Compressing the drainage device before closing the tab is a correct action. This helps to ensure that the device is functioning properly, and there are no leaks or obstructions in the drainage system.
Choice E rationale:
Clamping the drainage tubing for the next four hours is not recommended unless specifically ordered by a healthcare provider. Clamping the drainage tubing without appropriate orders may disrupt the normal drainage process and cause complications.
Correct Answer is B
Explanation
This is the action that the PN should emphasize for the client to take before self-administration of the nasal spray because it clears the nasal passages of mucus and debris and allows for better absorption of the medication. The PN should also instruct the client to shake the botle well, tilt the head slightly forward, insert the nozzle into one nostril, close the other nostril with a finger, and press the pump while inhaling gently.
