The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. The total volume after reconstitution is 2.5 mL.

After reconstitution, how many mL should be administered to the client?

(Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).

The most important intervention for the practical nurse (PN) to implement when applying an ice pack to a client is to secure a protective cover over the bag. This is essential to protect the client's skin from direct contact with the ice pack, which can cause tissue damage, frostbite, or discomfort.
Securing a protective cover, such as a thin cloth or towel, between the ice pack and the client's skin helps to create a barrier and prevent excessive cold exposure. It allows for the therapeutic benefits of the ice pack, such as reducing swelling and pain, while minimizing the risk of skin damage.
Incorrect:

A. While wrapping the bag in place for comfort is important, it is not the most critical intervention compared to ensuring the protection of the client's skin.
C. Giving directions to leave the pack in place is a general instruction for the client to follow the prescribed treatment, but it does not specifically address the importance of using a protective cover.
D. The type of ice used, whether crushed or cubed, may vary based on availability and preference, but it does not take precedence over the need to protect the client's skin with a cover.

The action the practical nurse (PN) should take in this situation is to administer a prescribed PRN (as needed) dose of analgesic.
Severe burning pain along the right side of the trunk is a common symptom of herpes zoster (shingles). Managing the client's pain is an important aspect of care to provide comfort and promote healing. Administering a prescribed PRN dose of analgesic will help alleviate the client's pain and improve their overall well-being. It is crucial to follow the client's prescribed medication regimen and provide pain relief as needed.
The other options are not the most appropriate actions in this situation:

B. Notifying the nursing supervisor of uncontrolled pain may be necessary if the client's pain persists despite appropriate interventions. However, the first step should be to administer an analgesic to address the immediate pain.
C. Giving the next prescribed dose of antiviral medication is important in the treatment of herpes zoster, but it does not directly address the client's current severe burning pain. Analgesics are specifically designed to alleviate pain symptoms.
D. Obtaining an oxygen tank for home administration is not indicated for the management of pain associated with herpes zoster. Oxygen therapy is typically used for respiratory or circulatory conditions and would not be the appropriate intervention for the client's symptom of severe burning pain.
